Does your NortLux T8 LED Tubes compatible with Lithonia Lighting fixture?

I'm switching from a 2-bulb T8 light fixture in my oil painting studio to a 4-bulb T8 fixture, based on the lumen recommendations (my studio space is 8.5' x 11.5'). I also film a lot of YouTube videos out of this space, and I need to improve the lighting output.

I just wanted to confirm that your NorthLux lights would be compatible with this fixture. https://www.homedepot.ca/product/lithonia-lighting-4-ft-t8-4l-32w-premium-wrap/1000730017?rrec=true

According to your lumen calculator, I actually need 5 T8 bulbs, but I'm hoping that the 4 will suffice. It'll certainly be better than just the two I have.

Our T8 LED lamps sound like a great fit for your oil painting studio installation.

​We've reviewed the Lithonia Lighting fixture, but unfortunately, we are unable to confirm if this would be compatible, due to insufficient information about the ballast contained inside the fixture. We realize it may be difficult to get additional information from a large manufacturer, but if they can provide the ballast model number, we would be able to confirm if it is on our compatible ballast list, which can be found below:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

Alternatively, our T8 LED-ready fixture may be a viable alternative, although we do realize that it is a two-lamp fixture that would fall short of the four-lamp quantity per fixture that you are looking for.

To supplement, you may also want to consider our T5 linear fixtures, which can be mounted on a variety of surfaces:

LED Strip vs Tube Lights in an existing T8 fixtures for Art Studio

I am helping my father order new lights for his art studio. We want to order LED lights to replace his T8 daylight fluorescent bulbs. We have two fixtures that hold six bulbs each. One fixture has a bad ballast that needs replacing; the other ballast was recently replaced.

I am trying to decide between T8 tube LEDs or adhesive LED strip lights. Your NorthLux 95 CRI T8 LED Tube for Art & Studio will work fine, but I will need to replace the ballast, correct? Or is there an easy workaround for that?

I heard that the tube lights waste a bit of luminosity because the light is directed upwards instead of all downward into the living (studio) area. On the contrary, strip lights are more efficient because ALL the light is directed toward the living area. So they are "brighter" and more lumens are shining directly into the living space. Correct?

If this is so, what product do you recommend for the strip lights for an art studio/gallery space? High CRI and color-accurate lighting are critical. My father is a professional portrait painter and color accuracy is (obviously!) important. 

Both our T8 LED tube lights and LED strip lights sound like a great option for your father's new art studio!

​In regards to your first question, you are correct on both the ballast as well as the "wasted" light situation. Unlike traditional fluorescent lamps, however, our T8 LED tube lights do not have a full 360 degree beam angle and are actually closer to 320 degrees, so there may be less concern with respect to wasted light.

​For an LED strip light solution, you will also want to consider the additional complexity of wiring and installation, as well as the additional component cost with power supplies and other accessories. That being said, we would perhaps recommend either our ABSOLUTE SERIES LED strip lights (99 CRI) or CENTRIC DAYLIGHT LED strip lights (95 CRI); links below:

As an alternative to LED strip lights, our T5 linear lamps could also be a viable option; we have provided a link for this product below:

Regarding tubes versus the strips, is there a noticeable difference in the amount of light received? Does each tube have one strip within it, or multiple strips? Is the wattage used the same?

The LED strip lights emit 450 lumens per foot, so this equates to approximately 1800 lumens for a 4-foot section, making this approximately equal to the 1800 lumens emitted by the 4-ft T8 lamp. The LED strip lights emit light in a narrower angle of 120 degrees, however, so they may be even better at reducing "wasted" lumens as we discussed prior.

The other advantage is that LED strip lights would provide you with the ability to quickly scale up or down the amount of brightness needed by installing multiple rows. Since the LED strips are quite narrow (less than half an inch), you would be able to install multiple rows in a fixture without worrying too much about footprint issues.

Is the T8 NorthLux light more suitable for art/gallery use than the strip options? The NorthLux is the only one in which there is text or reviews citing art studio/gallery use. I had assumed the Filmgrade White would be the best for artists and color rendition.

They all offer 95 CRI and 5000K, so we would not say that one is more suitable than the other. The product pages are shown primarily for marketing purposes, so if you're interested in the LED strip approach, that would certainly be fine.

The FilmGrade LED strip lights offer a color temperature of 5600K which is specific to the TV & film lighting industry. It is a perfectly suitable color temperature for art and gallery use, though keep in mind that it would not match any of the industry standards for printing or digital arts (D50 and D65, respectively).

I noticed that the Absolute offers less lumens (375/ft compared to 450/ft for the Centric and the NorthLux). Is the difference noticeable?

Yes, the difference would be noticeable, as the light output is approximately 15-20% less. That being said, installing multiple rows of the ABSOLUTE SERIES could be an easy way to make up for any brightness loss.

Lastly- (sorry for all the questions!)- if I order the T8 bulbs for my existing fluorescent fixtures, I can bypass the existing ballasts by connecting the incoming 120v wires to the blue/red wires that feed each of the "tombstones" that hold the T8 pins? Here's a short video showing that procedure: https://youtu.be/ts4dW8kLefY.

Yes, that would be a perfect way to ensure compatibility. we've included the installation manual for the T8 lamps below, which has information on wiring configurations:

LED Bulbs and Fixtures for Art Studio

Have looked but am unsure exactly what combination to order. Want a bank of three 4-foot. Need 90 or above CRT at least 5000 lumens

Our NorthLux products sound like a great fit for your art studio. For a quick-install solution, we would perhaps recommend our 4-ft T5 linear lamps, which can be installed and mounted onto a variety of locations.

We have included the product link below:

What I had in my old art studio was a bank of 4 – four-foot fixtures direct wired two tubes per fixture, direct wired and all connected to one main light switch. What I would like is 3- four-foot fixtures with two tubes per fixture. They will be hard-wired by an electrician and all operate on one main light switch.  

We would recommend purchasing three of our T8 LED-ready fixtures (2 lamps per fixture) along with two 4-packs of our T8 LED tube lights in 5000K.

We have included product links below. Please let me know if you have any questions!

LED Lighting for 10x12 ft Oil Painting Studio

I need to light a 10x12ft oil painting studio. Looking at your Northlux studio section I see many options in both bulbs and fluorescents. I also see 5000k or 6500K. So please help me out by recommending what I should buy and if it should be 500K or 6500 K. 

Our NorthLux LED lamps sound like a great fit for your painting studio.

We have several lamp styles, and depending on your interior layout and existing fixture locations, we would recommend different lamp types. If you can let us know if you have existing ceiling or lamp fixtures, or if this is for a new build project, we may be able to help refine your options a bit more.

In the meantime, you can get a sense of what level of brightness you will need using our lumen estimation calculator below to plug in the dimensions of your space:

https://www.waveformlighting.com/lumen-calculator

Concerning color temperature, our article below may help decide between 5000K and 6500K. In short, if you plan on incorporating natural daylight from a north-facing window, the 6500K may be a better option so that you can match this light, but if you don't intend to use any natural daylight, the 5000K may be a better option.

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

My studio is a small cabin with an interior dimension of 9x11 ft, an open ceiling that's 10 ft high in the center sloping to 8 ft walls with a ridge beam at the top. This ridge is in the center of the 11 ft axis. As for existing fixtures, I currently just hang lighting from the ridge beam and that location works fine just don't like my lighting. Existing windows are one small window facing west and 2 other small windows facing north but the ones to north are under a large overhang of about 6 ft.

I really only need one-half of the cabin lit well for painting. Glare is an oil painter's worst enemy but others didn't complain about it at all. So with the high ridge beam to mount it on do I need to be concerned? Is there anything about a LED light that would glare more than if I mounted some sort of track lighting and went with your bulbs?

In terms of the issue of glare, we have received some feedback from customers about the lack of a translucent cover on the lamps, which can result in glare when one looks directly upward at the light fixture. We believe the product review refers to this same concern.

​If we understand correctly, the primary concern with glare for painters is the reflection of the canvas, rather than the glare effect which results from looking directly at the light source. As such, we do not have any concerns about the product for your application, although it is certainly a valid concern in terms of visual comfort in the space.

Another alternative would be to utilize our T8 lamps in combination with our LED-ready fixtures. This would require some additional wiring and installation, but with our T8 lamps having a frosted cover, this may help mitigate your concerns about glare. We've included direct links to the 95 CRI / 5000K options and fixture below:

Flicker-free and T8 LED Tube Light Questions

So I’m doing research on LEDs and why some leds flicker and strobe. I see this is truly an issue as a lot of people deal with this problem. For the record, I’m talking about (visible) flickering/strobing. I know all LEDs flicker which we mostly can’t see, but causes headaches, fatigue, etc. But I’m dealing with visible flickering that driving me nuts. 

-Why does this happen with certain LEDs? 

-Will your “waveform flicker free” tube lights stop the visible flicker I’m having?

-And I’m very curious about what sets your lights apart from competitors with this “flicker-free technology”. Do you use a super high-quality driver in the bulb? 

Generally speaking, the flicker rate of often defined by the capability of the connected power supply. If the power supply is not adequately treating the power being afforded to the light source, then it will often encounter flicker. 

We are happy to confirm that our T8 LED Tube Lights offer flicker-free output due in part to the drivers within. If you would like to purchase and try these products, please feel free to take advantage of our 30-day return policy. We will gladly provide a prepaid return label for any unneeded items from domestic orders. 

I noticed that you have T8 tubes in a (non-flicker-free) and (flicker-free) but there’s no price difference. What’s the difference between them besides offering a different kelvin? Is there a time a non-flicker-free bulb has its place? 

All of our T8 lamps are flicker-free, but not all of our pages will necessarily indicate this. The underlying product, however, is the same (i.e. PN 4024), so you will see that the flicker performance is also identical.

So I currently have my fixtures rewired for double-ended power. And I see your tubes are configured to be used on single or double-end power. As I look closer there’s a problem, your spec sheet says (shunted) tombstones are required. I have non-shunted tombstones as all double-end power rewire configurations I've come across state there's no need to change the tombstones as non-shunted or shunted can be used with double-end configuration. Will this configuration not work with your bulbs? 

W have reviewed our product literature and it appears that connecting the lamps using the fixture configuration you describe is permissible using both shunted and non-shunted tombstones. Please see below, with the red square highlighting what would be your wiring method:

Do your bulbs and fixtures work on European current?

Do your bulbs and fixtures work on European current? I have fittings with electronic ballast. Will your tubes work with any type of ballast?

Most of our A19 bulbs, such as the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb, are available in the E27 base which is standard in Europe. 

Further, the power supplies that we have available for use with the LED Flex Strips can accept 100 - 277 V AC input voltage, where 230 V AC appears to be standard in Ireland. 

Further, if the model of ballast found within your fixture is not within our compatible ballast list, we would recommend bypassing the ballast so that the T8 LED Tube Lights use direct wire power. 

If the fixtures contain ballasts that are incompatible, our T8 LED Tube Lights will likely encounter damage which would void the product warranty, as those ballasts were initially intended for adjusting the power supplied to fluorescent tubes in ways that can damage LED hardware. 

Fluorescent LED Tubes Replacement

I would like to replace the fluorescent bulbs from my old grow light fixture. The bulbs are 1 3/8” in diameter and 47” long without measuring the prongs that stick out. Will your PhotonTube™ T8 LED Grow Light Tube for Horticulture fit in these old fixtures? 

Based on the dimensions provided, it appears that you are using T12 tube lights in a T12 fixture. In case it proves to be helpful, T5HO and T12 tube lights have slightly different dimensions as well as different power requirements. 

We can confirm that our PhotonTube™ T5HO LED Grow Light Tubes for Horticulture are compatible with existing 4-ft T5HO grow light fixtures & ballasts and would require ballast bypass for functionality with T8 or T12 fixtures, as illustrated within the installation guide. Unfortunately, any use with T12 fixtures without rewiring will cause hardware damage that will void the warranty due to the different power requirements. 

High CRI Lighting for Rebuilding a Studio

I am rebuilding my studio and am very excited about your high CRI lighting. Is it approved for use in Canada? My studio is 22x27 with 10 feet ceilings. I was thinking of the LED tube lighting - is this the best source?

By placing the dimensions into our Lumen Estimation Calculator, it appears that the space would be fully illuminated by 16-22 T8 LED Tube Lamps, though some of our customers prefer to illuminate just the working areas instead of the full space. 

For studio spaces we often recommend the 5000K or 6500K color temperature T8 LED Tube Lights since they can be more easily replaced if they encounter failures easier than the LED Strip Lights in our catalog can. These lights are suitable for use in Canada and are compatible with 120, 208, 240, or 277 V AC input voltages. 

While our T8 LED Tube Lights are compatible with some ballasts found within fluorescent fixtures, we recommend bypassing incompatible ballasts using the installation guide for operation. 

​Hardware damage may occur which would void the warranty if incompatible ballasts are used. As an alternative, our LED Ready T8 Fixtures do not require any rewiring for operation. 

What is the lighting difference between the two different types of your light fixtures. What are the advantages? How much area is covered by each light fixtures, and are they best to be butted against each other or allow space between? If there is space in between, what is the best distance without seeing a drop in lighting intensity? 

The primary difference between the LED Ready T8 Fixture models is that the Wrap Fixture with Prismatic Lens is designed to evenly diffuse the light, though it will reduce overall transmission by roughly 10%. This diffusion is also slightly more aesthetically pleasing than the Strip Fixture with Reflector. 

​Comparatively, the Strip Fixture with Reflector can be quite helpful for better dispersing the light in a space and directing light downward. This fixture also maximizes the total light output, and would not encounter any transmission loss as the Wrap Fixture with Prismatic Lens will. 

We generally recommend spacing the light sources evenly throughout a space to create a uniform light distribution, although we do not have a specific rule for the distance between the light fixture units. We do apologize for any impact this may have on your purchase planning. 

Is the NorthLux T8 LED Tube dimmable for an art studio?

Converting the room into a studio and was wondering if the NorthLux T8 95 CRI is dimmable and if can it be put on a dimmable switch.

Unfortunately, our T8 LED Tube Lights are not dimmable, and we do sincerely apologize for any impact this may have on your purchase planning process. That being said, we would be happy to share your interest in that feature with our product team for future development consideration. 

You might alternatively be interested in our LED Strip Light products, which are compatible with wall dimmers when utilizing our in-wall power supplies such as the TRIAC Dimmable Power Supply. Many of our customers like to illuminate their rooms by placing those items within our easily-installed aluminum channels at the ceiling line or on cornices. 

Fluorescent Replacement Lighting for Photo Gallery

About the Northlux 5000ºK LED tubes, what accounts for the difference I measured in CCT, and what is on the spec sheet?

Our official specification for the 5000 K LED tube lights is 5000 K plus or minus 180 K. The variation between what you measured and what is shown on our photometric report is likely caused by inherent color variation between lamps and lamp batches, as well as variations in measurement equipment, calibration, and precision.

We would expect that your spectrophotometer would also show variations between measurements, likely on the order of 25-50 K between measurements of the same lamp. Likewise, our photometric report showing 5064 K represents a single measurement only; repeated measurements of the same lamp would also likely show variation.

Also, R12 seems a little low. The spec sheet and what I measured both say 75. I noticed that the specs for R12 for the 5000ºK LED strip and what I measured are 91. Is this caused by batch-to-batch variation, or does the color of the glass in the tube have any effect? Do you use the same LEDs in all your lights?

Similar to color temperature, R12 can also vary significantly between lamps as well as measurement devices. The spectral reflection and absorption properties of the LED tube glass also play a role and are taken into consideration by utilizing different phosphor recipes for the underlying LEDs depending on the final product type (e.g. LED strip vs LED tube vs LED linear lamps).

Our end goal, however, remains the same with 95+ CRI and as tight of a color tolerance as possible.

6500K Natural North Light for Studio Room

I will be ordering 3 Northlux 96 CRI LED shop light fixtures from you.

Do I order for north light windowless art studio room

6500K light? Do I order the Centric daylight full spectrum FLICKER FREE T8 LED tube light or the Northlux 95 CRI T8 LED tube? Does the Northlux 95 for art studio flicker?

For my windowless art studio, I am purchasing three Northlux light fixtures from you. Do I order the CENTRIC DAYLIGHT full spectrum FLICKER FREE tube lights or the NORTHLUX 95 CRI T8 LED tubes?

By placing the dimensions into our Lumen Estimation Calculator, the space would be evenly illuminated with eight T8 LED Tube Lights. It could also be illuminated with four strategically-placed T8 LED Tube Lights if only the working areas require illumination. 

For artwork creation spaces where north-facing daylight is helpful, we generally recommend the 6500K NorthLux™ 95 CRI T8 LED Tube for Art & Studio. These lights provide full spectrum output and feature a high CRI of 95+. 

​Further, we can confirm that both the CENTRIC DAYLIGHT™ and NorthLux™ T8 LED Tube Lights are flicker-free. In case it proves to be helpful, the T8 LED Tube Light listings are identical products that are provided with unique landing pages for marketing purposes. As such, the 6500K option of either listing will provide identical output. 

It might also be helpful to know that not all fluorescent fixtures are compatible with T8 LED Tube Lights. While the ballasts within some models are compatible, incompatible models would require rewiring to bypass the ballast for a direct wire connection. 

We have shared a link below comparing the two options for artwork creation. If you would like to directly compare these options, please feel free to take advantage of our 30-day return policy. We will gladly provide prepaid return labels for any domestic orders within 30 days of delivery. 

Difference Between 5000K and 6500K Bulbs

T12 LED Tube Replacement for Barn Lighting

Right now, my barn is set up with Philips 37282-1, F96T12/DX/ALTO, Single Pin T12, 75 Watt, 6500 Kelvin, 4500 Lumens. I am looking for a possible LED to replace them with that would also simulate sunlight for the animals kept there. I have 25 double-tube fixtures. Any information and recommendations would be welcome.

While we do not have T12 LED products currently available, our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights are usable in T12 fixtures when bypassing the ballast to utilize line voltage. In case it proves to be helpful, the instructions for this process are within the T8 LED Tube Light product user manual. That being said, our T8 LED Tube Lights provide 1600 lumens each, which is less than the 4500 lumens provided by the current products. 

If you would prefer to utilize LED Strip Lights, we might alternatively recommend utilizing the 6500K FilmGrade™ WHITE LED Strip Lights, which are able to provide 450 lumens per foot. These lights are often installed within aluminum channels and can be powered using a matching voltage power supply, such as the FilmGrade™ DC Power Supply for LED Strip or the TRIAC Dimmable Power Supply. 

For an option that provides a closer simulation of natural daylight, we would alternatively recommend our 6500K ABSOLUTE SERIES™ LED Flexible Strips. Though more expensive per unit than the above FilmGrade LED Strip Lights, this item features a much higher CRI of 99, which is virtually indistinguishable from daylight. 

What's the difference between Centric, Northlux, and D50 T8 LED Tube Lights

I'm looking to retrofit an entire building and have several questions, is this form the easiest way to ask? What's the difference between Centric, Northlux, and D50, particularly when I can get the "same" part number from each product: 4025.50?

As a starting point, we can confirm that the T8 LED Tube Lights are identical products that are provided with unique landing pages for marketing purposes, which is why they use the shared part number. As such, identical output can be expected from the 5000K color point of each listing, and we do apologize for any confusion this may have caused. 

As a further note, it might be helpful to know that not all ballasts within fluorescent fixtures are among our compatibility list. If they are not, we recommend following the instructions within the user manual to bypass the ballast for direct-wire power. 

​We alternatively sell our own line of T8 LED Fixtures which are compatible with LED power requirements and would not require any rewiring or ballast bypass for operation. 

Flicker-free and Dimmable T8 or T12 Fixtures

Looking for fixtures that will continue to be the most cost-effective moving forward. Expecting we will add multiple drivers for several light series. Looking for drivers to run multiple lights with a high refresh rate, of 1000 megahertz? So as not to notice flicker when dimming. 

Though we do not have T12 tube lights or fixtures available, we are happy to confirm that our T8 LED Tube Lights and LED Ready T8 Fixtures can provide full-spectrum, flicker-free output without requiring ballasts or drivers for operation. These T8 LED Tube Lights are 48", provide a high CRI of 95+, and utilize the G13 base (Medium Bi-pin). 

That being said, please note that our T8 LED Tube Lights and Fixtures are unfortunately not dimmable nor compatible with dimmers. As such, they may not be the ideal light sources based on the installation requirements provided.

Do you have high CRI smart LED recessed lights?

Do you make high CRI smart/hub LED recessed lights? Ideally, that is dimmable with an adjustable color temp. Do you have any recessed options? Or are you aware of any high CRI recessed options on the market?

Unfortunately, we do not have any products in our catalog which match the details provided, and we would like to sincerely apologize for any impact this may have on your purchase planning. 

As of this moment, we do not have any recessed lighting fixtures available. The closest match in our catalog would be the LED Ready T8 Fixtures, which are designed for use with our T8 LED Tube Lights, though these fixtures are installed upon the ceiling surface rather than recessed within. 

Unfortunately, we do not have any specific alternate products on the market that we could recommend. 

LED Bulbs for Avian Lighting

We are a large wildlife rehabilitation organization. We have several large indoor rehab rooms that we house many species from songbirds to doves to raptors. I would like to know if you have tubes vs. bulbs.

We are happy to confirm that we have several avian products available in our catalog, such as the Avian Full Spectrum E26 BR30 LED Bulb for Birds and the Avian Full Spectrum E26 A19 LED Bulb for Birds. 

Though not specifically marketed for avian installations, we also have the 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights available which utilize the same full spectrum high CRI LED technology. 

​While our T8 LED Tube Lights are compatible with some ballasts used within fluorescent fixtures, it might be helpful to know that the ballast bypass process illustrated within the user guide can be used to make any T8 fixture compatible. As an alternative, you may also be interested in our LED Ready T8 Fixtures, which would not require any rewiring for compatibility. 

48' x 1.5" Full Spectrum for Office Lighting

I need 48' x 1.5" full spectrum lights for my office

Based on the dimensions provided, it sounds like the fixture currently in the office space utilizes T12 tube lights. If you would like to continue using the T12 fixture with a new set of T8 LED Tube Lights, it will require a ballast bypass to be compatible with our T8 LED Tube Lights. 

As a general note, it might be helpful to know that older fluorescent fixtures contain ballasts that are not compatible with the energy requirements of LED technology. And while our T8 LED Tube Lights are compatible with some T8 fixture ballasts, any connection to operating T12 ballasts will cause hardware damage and void the product warranty. 

If you would like to rewire your fixtures to bypass the ballast in favor of a direct wire connection, we would recommend our 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. This color temperature is most commonly recommended for office installations such as yours. 

Fluorescents (EIKO lights) Replacement for Painting Studio

I have a small painting studio, about 11' x 12'. I currently have two compact fluorescents (CRAPPY CRI) EIKO lights overhead that is about 85W each. I'm looking to replace them with your excellent bulbs. I can install a T8 fixture but am not sure how many I need, or which color bulbs to get for sure. I want a balanced light so I'm thinking probably 5,000K. Maybe a mixture? Also, do I just need two bulbs? Would four be too much for this small space? 

Based on my use of the Lumen Estimation Calculator, we would likely recommend utilizing four of our 1800 lumen T8 LED Tube Lights for your studio space. We generally like to recommend the 5000K color temperature option for artwork creation as it produces a neutral, balanced white color which is great for color-critical installations. 

If you utilize a third-party fluorescent fixture, it might be helpful to know that older fixtures often used ballasts for power adjustment. As not all ballasts are within our compatibility list, we generally recommend rewiring the fixtures to bypass the ballasts. This process is fairly straightforward and is featured within the T8 user manual. 

We hope that our high CRI T8 Tube Lights are a great match for your studio! 

T8 LED Tube Light to T12 Fixture Installation Guide

I just ordered 24 color-matching 4 ft led tubes. I am putting them in T12 fixtures. Can you send instructions for wiring 

We have shared a link for the T8 LED Tube Light user manual below, which contains the ballast bypass instructions.

Facelift Lighting Dental Office

We are a dental office bursting at the seams. We have had to move our marketer and another person into the basement. We've built a room there, but there are no windows. I would like to make the room as brightly lit as possible with tons of windows. I'm hoping for advice on how to do this. There is one light fixture in the center of the ceiling, and I want the biggest, worst light fixture with the very best full-spectrum/therapy-type bulbs in it for him.

Also, we'd like to replace all of our fluorescent bulbs with something that is both better for our team members as well as for color matching (for veneers and crowns, etc).

If you would like to let us know what the dimensions of the basement area are, we would be happy to plug those into our Lumen Estimation Calculator to see what the recommended illumination target would be. ​

In the interim, we would likely recommend our D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) for the office lighting, which provides full-spectrum light with a high CRI of 95+ and are designed with color-critical installations in mind. These tube lights are compatible with many types of fixtures, though the fixtures may need to be rewired for ballast bypass if they do not contain a compatible ballast. 

If you would prefer to utilize a new fixture, you may be interested in our newly launched T8 fixtures, including the LED-Ready T8 Tube Light Fixture - Wrap Fixture with Prismatic Lens. ​As our fixtures are designed with LED technology in mind, they would not require any rewiring for operation. 

Replacement for Daylight fluorescent bulbs

I was wondering if you could help us with trying to specify the correct LED solution to replace the daylight fluorescent bulbs we are currently using at our live animal shows. We would love to switch to LEDs, but since we are judging the animals on the color and quality of their fur we need to be as consistent as possible between the LEDs and the old fluorescents that are the current industry standard. 

The bulbs we currently use for the shows are Philips F96T 12/DX Alto and GE F96DX which are both 8' long. Our show table is usually 16'-24' long and we are trying to get a consistent, even light across the length, hence using the 8' bulbs. 

For my own use, I'm looking at ordering a pack of your Centric Daylight T8 tube lights to try out, but I'm not sure that 4' long bulbs would be ideal for the long show lights. The strip lights seem ideal as they would give us lots of flexibility on storage and set up, but I'm not sure that they would give us the same even, more diffuse light that the linear bulbs do. Currently, the bulbs are 28" above the table. 

Though we were unable to locate any details about the GE F96DX, based on my review of the Philips F96T 12/DX Alto product it appears that each 8 ft tube light provides 4200 lumens (525 lumens per foot) with a CRI of 90. 

The primary recommendation that comes to mind as an alternative is our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. Though these provide a lower 1800 lumens per 4 ft tube (450 lumens per foot), they also provide a greater CRI of 95+. That said, please note that these lights are not compatible with all ballasts found in T8 fixtures, and may require rewiring to bypass the ballasts. 

The second option would be our FilmGrade™ WHITE LED Strip Lights, which feature the same lumens per foot and CRI as the above product. The primary benefit of the LED Strip Lights is that one full 16.4 ft reel can be powered using a single power supply such as our FilmGrade™ DC Power Supply for LED Strip or TRIAC Dimmable Power Supply (for more permanent installations). These items can be installed within the aluminum channels, which feature a diffusion panel for uniform light distribution. 

As the above products would feature a substantially higher CRI than the currently utilized Philips and GE products, we might recommend purchasing an initial test order containing one unit of our 2 ft or 4 ft 6500K CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures to test on your show table to ensure that the color quality matches the industry standard. 

These T5 Linear Light Fixtures utilize the same LED technology as the above products, though they would not require any additional connectors or power supplies for operation. These fixtures can also be daisy-chained (or interlocked) together for a maximum length of 70 feet, which may make them a good third option for your show table installation. 

Ultra High 95 CRI 6500K T8 LED Tube Photometric Report

Is there any available testing report for Ultra High 95 CRI 6500K T8 LED Tube for Jewelry & Display?

We have shared a link to the photometric report for the 6500K Ultra High 95 CRI 6500K T8 LED Tube for Jewelry & Display below, for your reference.

Lighting from Home Office in Room with No Windows

I’ll probably want to change some lighting in my studio, too, at some time. I bought what I have from you but not sure you had the stick ceiling lights then. To me, they're fluorescent with one of those clear coverings. 

I checked our basement wall color on your site, an aqua, and I believe it came up to 97%. I’m into LRV so watch for that when picking paint colors. 

There are no windows. The ceiling is white with a sheen. The bottom half of the walls are wood, stained grey. Not a grey that would be my choice now since it’s on the warmer side…flooring is the same. 

The height is 7.5”. I can give you the other measurements later as they’re upstairs in my studio at the moment. 

Our first thought is to explore looking into replacing the fluorescent lamps while retaining the fixtures that are already in place. This would be the most straightforward way to immediately improve the lighting quality in your son's room.

​Specifically, our CENTRIC DAYLIGHT T8 LED tube lights would be a great option for such a replacement:

If you can confirm if the fixture is a 4-ft, T8, or T12 fixture, that would allow us to confirm if our lamps are compatible.

If not, we'll want to look into other options such as replacement bulbs for floor lamps and fixtures - see below:

Recessed LED Light for an Art Studio

I would like to talk to someone about adding lights to my art studio. I have an electrician scheduled, but he doesn't seem to know much about this subject. I was planning on putting in recessed LED lights but am now wondering what you would recommend.

Though we do not have recessed lighting fixture options, we would be happy to provide you with some product recommendations if you would like to share some details about your studio with us. For example, it would be helpful to know the size of the space, including the ceiling height. 

For a simple installation, you may be interested in our NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio, which are designed to be installed within recessed canned ceiling lighting. 

If you would like to utilize ceiling fixtures using a direct-wire connection, we might recommend our newly-launched LED-Ready T8 Fixtures, which are designed to be compatible with our T8 LED Tube Lights. 

If installing LED Strip Lights in the cornices of your walls is more beneficial for even illumination, we would likely recommend our 5000K 24V CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail, or our 6500K 24V FilmGrade™ WHITE LED Strip Lights. 

I have measured my art studio (which is actually a bedroom) and it is 13’7” long, 10’3” wide, and 8’ tall. There are 9” open bookshelves on one of the 10’ wide walls and two windows that face West. There is one light in the middle of the room.

I was thinking about putting in 4 flat recessed LED lights in the four corners of the room. Probably 2–3 feet away from the walls. 

I’m assuming the Northlux 95 fits in the older style of recessed cans which in the past have been quite large. But I don’t really know. Can you tell me what size can (dimensions) I would need?

And I don’t know how the other options would work. I have forwarded your email response to my electrician, but I haven’t heard back from him.

I am an oil painter and consequently need not only good lighting but accurate lightning.

We have attached an image that lists the dimensions of our NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio in millimeters, which we hope is helpful for your canned lighting installation planning.

These lights should fit into any standard E26 base, though please feel free to take advantage of our 30-day return policy in the event that they wind up not being the right fit. We will gladly provide you with a prepaid return label for any unneeded items. 

Based on my use of our Lumen Estimation Calculator, it appears that a room of the dimensions provided would benefit from 11,095 lumens for thorough illumination, though each space varies depending on the needs of the illumination target. As each of our BR30 bulbs provides 800 lumens, your space may benefit from additional light sources, such as the aforementioned products or the NorthLux™ 95 CRI T5 LED Linear Light Fixtures. 

The NorthLux™ 95 CRI T5 LED Linear Light Fixtures do not require additional power supplies or accessories, and can be easily installed on many different surfaces using the included magnets and metal clips, which can be useful for installations that benefit from a moveable light source.

Would the LED strips be installed in place of the current T8 fixtures?

NorthLux™ 95 CRI T8 LED Tube for Art & Studio 4024.50.4P. Is this lamp dimmable?

Unfortunately, none of our T8 LED Tube Light products are dimmable. For installations where dimming is helpful, we typically recommend our LED Strip Lights as alternative light sources. 

How are they installed? In the diagram attachment, we are needing a high CRI above the conference table for viewing new products and comparing the color of shipments to the original color. Would the LED strips be installed in place of the current fixtures? 

We can confirm that our LED Strip Lights can be used for both commercial and residential installations. Installations commonly utilize runs of the LED Strip Lights installed within the aluminum channels, which are controlled using smart home systems or wall dimmers and powered with supplies such as the 12V TRIAC Dimmable Power Supply. 

For installations where color accuracy is important, we would likely recommend our D50 or D65 ABSOLUTE SERIES™ LED Flexible Strips, which can output light that is virtually indistinguishable from sunlight. 

If the lights are to be installed within a retrofitted T8 fixture, our primary recommendation would be to ensure that the power supply can comfortably fit within or around the fixture. Some customers choose to utilize the cavity where the ballasts were previously held for such installation. 

Can you give me a drawing of what you speak? Can’t visualize it 

Though we, unfortunately, do not have precise installation schematics on file that we could provide, we have shared a few LayoutMap links below that illustrate installations using connected segments of our LED Strip Lights powered by the TRIAC Dimmable Power Supply. We do hope that these resources prove helpful for your installation planning. 

​The CENTRIC HOME/DAYLIGHT LED Strip Lights featured within the below links are very similar to the ABSOLUTE SERIES™ LED Flexible Strip, though the latter has barrel jack adapters on the reel ends for power connection. As such, we would recommend using the Female DC Barrel Jack Plug Adapter to connect the wiring without requiring soldering. Doing so also makes future adjustments and troubleshooting easier, as the Flex Strip can be detached.

Should I remove the warning sticker on NorthLux T8 tube bulbs upon installation?

Connected to the Wago connectors in your 4’ fixture successfully. This may be a naive question, but do I remove the printed clear plastic stickers on the tubes (NorthLux™ 95 CRI T8 LED Tube) - the ones giving warnings and technical info, or just leave them on while using the lights? 

After speaking with my product team, it appears that the stickers are intended to remain on the products so that the ETL marking and other product details can be identified in the future. These stickers are located on the underside of the products so that they won't limit the light output in any way. 

Color Accurate T8 LED Tube Light for Photography Lighting

I design and build photography stations for the pre-loved clothing industry, for these fully enclosed units I have been using Quasar T8 and T12 tubes, I have had several failures and I am looking to change my supplier, can you please advise if your tubes are color accurate such that all tubes will give an identical color rendition, even if different batches are used. Do you supply mountings of any kind or would I just use generic mounting clips? 

We are happy to confirm that our lighting products undergo strict testing to ensure that they can uniformly illuminate with very little tolerance for variability. 

If they prove to be helpful, we have provided a link to our set of product photometric reports below. Included in this link are the reports for our 5000K and 6500K T8 LED Tube Light products, which we often recommend for installations where accurate color calibration is important. 

5000K NorthLux™ 95 CRI T8 LED Tube for Art & Studio - Report

6500K NorthLux™ 95 CRI T8 LED Tube for Art & Studio - Report

Further, the T8 LED Tube Lights utilize the G13 Medium Bi-Pin fixture power connection. 

Does your T8 LED Tube compatible with Australian power specifications?

We have currently taken a lease in a new office, which is currently undergoing some minor work. We are photographers and we plan to use the office space for color-accurate post-production work. We won't be photographing in the space. To reduce any color cast, we are currently repainting the walls to a neutral tone. Further, the current fluorescent lights produce a biased tone, which we would like to eliminate. 

Would you know whether you're LED tubes are compatible with Australian power specifications? Secondly, for our purpose I came across three options on your website; the Centric Daylight, NorthLux & D50 5000k T8 LED Tube. Could you advise which one better suits our needs? 

We can confirm that our T8 LED Tube Light products are compatible with 120 – 277V AC (50-60 Hz). According to our review of the line voltage in Australia, this appears to be compatible. 

As a final note, we can confirm that the NorthLux™ 95 CRI T8 LED Tube for Art & Studio, CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light, and D50 5000K T8 LED Tube Lights for Color Matching are identical products which are provided unique landing pages for marketing purposes. 

The only differentiator between each of the product pages is the available color temperature options, and we do sincerely apologize for any confusion this may have caused. Due to this, the 5000K or 6500K options will provide identical full-spectrum light output. 

​That said, it might be helpful to know that these T8 LED Tube Lights have not received compatibility testing with ballasts that may be in Australian fluorescent fixtures. As such, we would recommend using the installation guide to bypass the ballasts. 

​Please note that when these products are used with unsupported ballasts, they may encounter performance issues that will void the product warranty due to the difference in power requirements. 

T8 LED Light Bulb Recommendation for Printing Studio

I am re-lighting my workspace and trying to decide between the Northlux 5000k T8 replacement bulbs and the D50 5000K T8 LED Tubes. Could you tell me what the difference is between them? We are a printing studio and have to evaluate photographs and paintings for color reproduction.

As a starting point, it might be helpful to know that the D50 5000K T8 LED Tube Lights for Color Matching and NorthLux™ 95 CRI T8 LED Tube for Art & Studio are identical products that are provided with unique landing pages for marketing purposes. 

The above can be noted by the shared part number on the product page (4024.50) As such, identical ISO D50 calibrated light output can be expected from both of the above 5000K options. We do sincerely apologize for any confusion that the product pages may have caused. 

Fluorescent Bulbs Replacement for Dental Operator's Lighting

High CRI is a top priority. Shade matching is critical for dental work. Currently have two fixtures per operatory. Does each fixture have two 8ft fluorescent bulbs (32ft of fluorescent total)? Suggestions for an LED upgrade? 

Based on the details provided, we would recommend purchasing our 48” D50 5000K T8 LED Tube Lights for Color Matching as well as our LED-Ready T8 Fixtures. 

These lights are designed with color-critical installations in mind, offering a high CRI of 95+ and full spectrum output. Further, they are fully compatible with the fixtures without requiring rewiring or ballast bypass, unlike many third-party T8 fixtures. 

Do you have any options to replace bulbs in the existing T12 for 48" and 96"? Intending to use for operatory with the dual purpose of shade match and general lighting. What is the difference between D50 and D65?

While T12 fixtures are incompatible with the power requirements of T8 products, this obstacle can be overcome by rewiring the fixtures to bypass the ballast. This process will prevent the ballast from damaging the T8 lights. 

The instructions for this process can be found in the product user manual, which we have provided a link to below. We have also attached a guide to an article describing the differences between the D50 and D65 standards, which we hope is helpful for your purchase planning. 

T8 LED Tube Light - User Manual

Difference Between 5000K and 6500K Bulbs (ISO D50 & D65)

I better understand 50 v 65 now. Am I correct to think 5000k is the best for a dental operator?

Our 8ft fixtures have plunger-type connectors. Is there a D50 LED to retrofit this? Planning to bypass the ballast.

Based on the conversations that we have had with labs and other medical offices where color calibration is important, it does appear that the D50 color point is the most popular option for ensuring color accuracy. 

Regarding the connectors, it might be helpful to know that our T8 LED Tube Lights use the G13 base (Medium Bi-pin). As such, they may not be compatible with the fixtures in your office. If you would like to provide us with some photographs of the base connection within the fixture before ordering, we would be happy to review them to ensure compatibility. 

As a final note, our T8 LED Tube Light products are not compatible with all ballasts found within T8 fixtures. Before installation, we would recommend checking the compatibility list and bypassing the ballasts if they are not supported. 

Will the Seagull Lighting Fixture work for the Centric Daylight T8 LED tube?

I want to change my fluorescent bulbs to LEDs. Currently, I have:

Seagull Lighting Fixture/Model 59132LE-15/120V 60hz, 64W, 0.8Amps. Use F32T8 Replacement lamps only, E192796 Suitable for damp locations/Bulb Type: 2 medium bi-pin T-8 32w/Ballast: 120v Electronic NPF ENERGY STAR Qualified Offers energy-saving fluorescent lighting.

Will they work for the Centric Daylight one, or is it different from that one? If the other instructions will NOT work, do you have instructions for the Centric one?

Based on my review of the details provided, it unfortunately does not appear that the ballast within the fixture is compatible with out T8 LED Tube Lights. If you have a specific model number for the ballast, please let us know and we would be happy to check it against the list. 

That being said, we are happy to confirm that the ballast bypass instructions for direct wiring the T8 LED Tube Lights are identical across both the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light and the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. As such, please feel free to utilize the user manual featured for either product. 

Would the T8 LED tube be compatible with British T8 fixtures?

I'm based in London, England. I was interested in the T8 LED daylight tubes for artists. Do you sell your products in the UK? Also, would the T8s be compatible with British T8 fixtures? Assuming you do sell to the UK, roughly how long would it take to deliver? 

We are happy to confirm that our T8 LED Tube Lights are compatible with 120-240V AC, 50-60 Hz input voltage, and can be shipped to the United Kingdom without delay. 

As our ballast compatibility list is centered around fixtures sold in the United States, please note that any ballasts found within your T8 fixtures are likely not featured in our compatibility list, which would cause performance issues and may void the product warranty if installed. 

That being said, we have prepared a set of simple instructions for bypassing the ballast with a direct-wire connection, which will allow for optimal product operation. 

I haven't actually gotten the T8 fixtures yet. So would it make more sense to purchase the fixtures from you too, (and would that have conversion implications for wiring them up in a UK system?). 

It was brought to our attention that the LED-Ready T8 Fixtures are designed for the voltage standards of North America and have not been tested for use with United Kingdom voltage standards. 

Given this, we would likely recommend purchasing an option that is locally sourced and capable of utilizing the local voltage. While we stand by each of our products, we would prefer to avoid recommending the purchase of any items that may not be fully usable in your region.

When an alternative T8 light fixture is purchased, we would recommend bypassing the ballast as illustrated within the product user manual for direct-wire connection. This is due to the fact that our T8 LED Tube Lights are unlikely to be compatible with the ballasts designed for flourescent fixtures in the United Kingdom. 

In which case, I'll get the T8 tubes from you and get the T8 batten fittings over here (and do the bypass). Just to double check, will the American T8 tubes actually fit the British T8 batten fittings?

Based on our previous conversations with customers using these lights internationally, We have not encountered instances where our 48” T8 LED Tube Lights have been incompatible with UK fixtures. 

That being said, we would strongly recommend reviewing the electrical specifications section within the product specification sheet and confirming compatibility with local hardware stores or electricians. 

Flicker-free T8 LED Tube Lights Recommendations

I have a small motorcycle repair shop and replaced all my fluorescent bulbs in 2017 with Kobi Electric T8-F4-1540-RMV K6P2 LED T8 Rewire 15W 1800lm frosted 4ft tubes. 

The light output was superior to the old tubes, and I was very happy with them until recently. I noticed I was getting eye strain to the point where I started wearing a cap, and then I started getting a "car-sick" feeling shortly after I entered the shop. 

You have many tubes to choose from, and the CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Light looks to be what I'm looking for, but I wanted to confirm this and am open to other suggestions.

Based on the details provided, it seems that our full-spectrum flicker-free T8 LED Tube Lights would be a great option for reducing the eyestrain in your repair shop. For your industrial installation, we would recommend the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. 

In the hopes that it proves to be helpful for your installation planning, please note that the ballasts found in most fluorescent fixtures are not compatible with the power requirements of our LED T8 Tube Lights. 

As such, we would recommend checking the compatibility sheet to ensure functionality. If the ballast within the fixture is not listed, we then recommend rewiring the fixture for a ballast-bypass direct connection so that they operate without issue. When T8 LED Tube Lights are used with incompatible ballasts, they may encounter issues that will void the warranty. 

LED Lighting for Birds

I was hoping to order LED lights for birds that are not individual light bulbs but either strips or tube lights. Do you have anything like that for birds? 

While not specifically marketed for birds, we are happy to confirm that the same LED technology found within our avian A19 and BR30 lightbulbs can also be found in our T8 LED Tube Lights and LED Strip Light products. 

As such, you may be interested in our 4000K and 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are designed to be compatible with our newly launched LED Ready T8 Fixtures. 

For an LED Strip Light option, we might recommend either the 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail or the 6500K FilmGrade™ WHITE LED Strip Lights in 12V or 24V. These lights can be mounted within channels, paired with in-wall dimmers, and powered with DC power supplies or in-wall power supplies

Can I surface mount the LED Shop Light Fixture?

Can I surface mount these fixtures on the bottom of the floor joists exposed in my basement?

As the LED Shop Light Fixtures are designed for hook and chain mounting rather than surface mounting, they may not be the ideal product for your installation. We do sincerely apologize for any impact this may have on your purchase planning. 

For alternative options, we might recommend our recently launched LED Ready T8 Fixtures, which are designed to be compatible with our T8 LED Tube Light products. 

As a further option, you may also be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixtures. While these products utilize DC power cables for operation, they can be easily mounted to several types of surfaces using the included brackets and accessories. 

T8-style Fixtures with Flicker-free Lighting for Video Production Studio

I'm designing a video production studio and am trying to find T8-style fixtures with flicker-free bulbs to use as fill lights. Do you have customers that have used your products for video production before? Flicker is evil, of course, but there are other qualities of LED lights that can impact video recording. 

We are happy to confirm that several of our products, such as the film & photography line products, are designed with video and photo capture in mind. Our T8 LED Tube Light products are also flicker-free so long as they are paired with a compatible ballast or rewired for ballast bypass and also offer a high CRI of 95+ as well as full spectrum output. 

For your installation, we might specifically recommend our new line of LED-Ready T8 Fixtures. These fixtures do not contain the problematic ballasts that many retrofit fixtures utilize and are compatible with our NorthLux™ 95 CRI T8 LED Tubes for Art & Studio without requiring rewiring. 

Ceiling Mount Light Recommendation for Workshop

I moved into a new workshop with 12-foot ceilings. Currently, it is lit by 8-foot fluorescent fixtures, which are not quite bright enough and have a horrible color rendering. I need help navigating your catalog to determine what the best solution is. I'd like to flush-mount new lights to the ceiling; do you have an option for this with direct wiring?

While we do not have any 8’ fluorescent tube lights that we could provide lighting options for, we do have several options which could be a great match for your new workshop. 

Our primary recommendation would be our newly launched line of LED Ready T8 Fixtures, which are designed for line voltage and are compatible with our High-CRI T8 LED Tube Lights. For this installation type, we would likely recommend the NorthLux™ 95 CRI T8 LED Tube for Art & Studio in the 5000K or 6500K option. 

As a secondary recommendation, you may alternatively be interested in ceiling-mounting lengths of our LED Strip Lights within our line of aluminum channels. These products can be paired with in-wall power supplies and wall dimmers, and are available in a wide variety of color temperatures.  

For the Fixtures, do you recommend the prismatic lens or reflector if I want the most light hitting the work surfaces?

For an installation where the maximum lumen output is preferred, we would recommend the LED-Ready T8 Tube Light Fixture - Strip Fixture with Reflector. 

​While the prismatic lens is helpful for diffusing light, the lens also reduces overall light transmission by roughly 10%. As such, only 90% of the light being provided by the T8 lights can pass through the prismatic lens and onto the work surfaces. 

Do you have an idea of how much light (brightness) I can expect from each pair of the 2 T8 LED tubes? Specifically how they will compare to the pair of 8ft fluorescent lights that I have now? I'm wondering if I can replace these 8ft Paris with your 4ft pairs or if I need to double up and purchase twice as many 4ft pairs and rewire the ceiling, a step and expense I'd like to avoid if possible. 

Any reason you recommend the Northlux instead of the Flicker Free Centric tubes? Flicker Free seems like a very useful feature for the little bit of photography I do.

As the lumen output differs from product to product, we are unfortunately not aware of the specific output that your 8-foot T8 fixtures might provide. That being said, we can confirm that our T8 LED Tube Light products provide 1800 lumens per unit. As such, an installation using four-4 foot T8 LED Tube Lights would provide a combined 7200 lumens. 

As a final note, we can also confirm that the NorthLux and Centric T8 LED Tube Lights are identical products that are provided with unique landing pages for marketing purposes. As such, identical flicker-free output can be expected from both product lines. 

95 CRI LED Lights for Art Studio

My wife ordered and received NorthLux 95 CRI T8 tubes. She thought we would just find a fixture. We are in new construction and therefore do not have existing old fluorescent fixtures and they cannot be bought. The tubes were recommended by lots of artists. Do you have a fixture for this type of LED that gives this “artist” light? We need 2 sets of 4 ft linked together with each set linked to the other. Need to know if they can be hard-wired and if are they wired from the end; and does it matter which end? 

We are happy to confirm that the T8 LED Tube Lights in our catalog are compatible with our newly-launched LED Ready T8 Fixtures. These new fixtures can be direct-wired to line voltage and do not require any rewiring or adjustment for functionality as some older fluorescent fixtures might. 

As an alternative, you may also be interested in our NorthLux™ 95 CRI LED Shop Light Fixtures. These products are integrated fixtures that do not require T8 lights or other for functionality and can be daisy-chained to a shared DC power source. That being said, please note that these fixtures are unfortunately not designed for line voltage. 

Can the LED Ready T8 Fixtures be daisy-chained? I am considering the two options you listed.

I would be placing lights on two beams running parallel and would like 8 feet on each beam which means linking two 4-foot fixtures. Can I jump over from one beam fixture to the other beam fixture and does the jump wiring have to be on a certain end? There are no diagrams indicating how this might be done.

Finally, do the T5 fixtures have similar artist LED light as the T8 fixture and what is the difference in getting one or the other?

Unfortunately, the LED Ready T8 Fixtures cannot be daisy-chained, as they only have one set of input wires and do not have output wires or receptacles. 

We can confirm that the NorthLux™ 95 CRI T5 LED Linear Light Fixtures are available, and are designed with art and studio installations in mind. 

This item is different from our T8 LED Tube Lights in that it is an integrated fixture that operates with a DC power plug. These fixtures can also be daisy-chained using the included C7 power cable, and provide full spectrum light output with a CRI of 95+. Comparatively, the LED Ready T8 Fixtures are designed for line voltage and ceiling installation, and require the T8 LED Lights for operation. 

The T5 fixture is being integrated and the DC power plug does not seem to fit with the hard-wired electrical my contractor has installed. Do you sell the 95 CRI T5 LED tubes without the fixture? If so I can look for a different fixture that I could put your lights in.

Our T5 Linear Light Fixtures are only designed for use with DC outlet power. We apologize! 

As a further clarification, the T5 Linear Light Fixtures are not sold separately from the fixture. 

Based on the details provided, it seems that the best option might be the aforementioned LED Ready T8 Fixtures as well as the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. 

As another alternative, you may also be interested in using our LED Flex Strips which can be installed within Aluminum Channels and powered using direct wire as a TRIAC Dimmable Power Supply. 

Do you have fixtures that work with your PhotonTube™ T5HO LED Grow Light?

Do you sell fixtures that will work with your PhotonTube™ T5HO LED Grow Light Tube for Horticulture? I'd like to purchase either two-tube or four-tube fixtures that will work with your bulbs when I purchase them. 

Unfortunately, we do not currently have any fixtures that are designed to house the PhotonTube™ T5HO LED Grow Light Tubes for Horticulture. We would like to sincerely apologize for any impact this might have on your purchasing process. 

That being said, based on my review there appear to be several T5HO fixtures options available from other online retailers such as Amazon and Home Depot. 

I have several LED T5 fixtures that have L and N labeled at one end and NOP at the opposite end. I’m guessing that the L/N end is for Line and Neutral and the other end is for No Power. Will your PhotonTube Grow Light Tubes work in this kind of fixture?

Based on the details provided, it does appear that the fixture would be compatible with our T5HO lights. 

As a further note, we would also recommend checking the fixture ballasts to ensure compatibility. If they are not compatible, the T5HO lights can be made compatible by rewiring the fixture to bypass the ballast. 

36" LED Tube Light for Birds

I’m looking for a 36" tube LED that has 5000K to 5700K with a CRI of 90+ at 12 volts if possible.

While we do not have any 36” tube lights available, you might alternatively be interested in our LED Ready T8 Fixtures, which are compatible with our 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights.

For a different option that would not require an additional fixture, we would recommend our 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixtures. These products can be easily mounted to surfaces, offer a high CRI of 95+, and would only require access to a wall outlet for power. 

Do you know the foot candles of a 2-light fixture would produce using T8 LED bulbs?

I'm looking at the Photon T8 LED Grow Light Tubes for Horticulture. I have a 2 tier grow light for houseplants (live in an apartment with trees to the south and an overhang entry to the north.) I currently have the two 40-watt T8 fluorescent bulbs that came with it, but they have been in there about 1 3/4 years, so now it's definitely time to replace the bulbs. Are the Photon LED 4000K good for flowering? Do you know the footcandles that a 2-light fixture would produce using these bulbs? Are these brighter than a 40-watt T8 fluorescent bulb?

Our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light provides 1800 lumens of output, which is equivalent to 32W fluorescent lamps.

For a more complete answer regarding the operating temperature of the LED lighting about the spacing between plants and fixtures, it might be helpful to know that we measure an average temperature rise of 54°F (30°C) over ambient temperatures when the LED products are operating. 

​Hopefully, this average temperature rise helps identify the ideal distance between the plants and the light fixture, based on the relative heat sensitivity of the plants being grown. 

Flicker-free and Low Dirty Electricity Light to Convert 4" T12 Fluorescent Fixture

Looking for low dirty electricity, low flicker, and soft white type of color temp option to convert an existing 4' mag. ballast fluorescent fixture w/ T12 bulbs. What would you recommend? 

When using our T8 LED products in a T12 fixture, we strongly recommend rewiring the fixture so that the ballast is bypassed. The instructions for the ballast bypass process are illustrated within the T8 LED Tube Light product specification sheet. 

​When the ballast has not been bypassed in lieu of a direct-wire connection, electrical hazards may occur which will damage the hardware and void the product warranty. 

​While we would typically recommend the 3000K color temperature for soft white output, we unfortunately do not have T8 LED Tube Lights available in that color point. As an alternative, you may be interested in our 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. 

​These products are also compatible with our newly launched line of LED Ready T8 Fixtures, which would require no rewiring or ballast to bypass. As a further note, we can confirm that our products do not create ‘dirty electricity’ as defined by the FCC. 

T8 LED Lighting for Painting Studio

I’m a professional painter who typically does paintings in the 5’ or 6’ square size range. My studio has 9 1/2’ ceilings. I’m thinking of using your 5000K, CRI 95, R9 4ft LED tube lights and your $85.- 4ft shop-light fixture. I have a few questions.

How does that sound? I can of course adjust the length of the chains I use when hanging the fixture from the ceiling, and move the painting on my easel more under the light or further back.

The installation as described sounds like a terrific option for illuminating your canvas! As a further note, we can confirm that the BR30 lights can conveniently fit within clamp fixtures for directional lighting. 

Does your reflector fixture sound best for me (angled slightly away towards the canvas surface so as not to come in my eyes as I observe the painting from a distance) ? or would you recommend your fixture with the diffuser cover? 

Unless the prismatic diffusion of the light output is required for your installation, we would likely recommend the LED-Ready T8 Tube Light Fixture - Strip Fixture with Reflector. 

Does the diffuser fixture (# 4501) reduce the light output a lot? Does it affect the CRI or R values? 

We can confirm that the prismatic lens will cause a ~10% transmission drop in the total lumens being output, though this transmission reduction is not expected to affect the CRI or R values. 

I wasn’t able to see R values for Northlux 95 CRI BR30 bulbs (#4011.5). Can you provide those? Do you sell a fixture for that bulb? 

We, unfortunately, do not yet have the photometric report available for the 5000K NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, though I expect this report to be uploaded to our website within the near future. 

I see the (#4011.5) bulb is dimmable. How about the Northlux 95 CRI T8 LED Tubes (#4024. bulbs using your (#4502) fixture? Can I dim them with that fixture? If yes, how does dimming affect the CRI and R values of the light?

Generally speaking, our T8 LED Tube Lights are not compatible with dimmable fixtures, and we do sincerely apologize for any impact this may have on your purchase planning. 

D50 T8 LED Tube Light Color Matching for Print Studio

I have a color print studio. The viewing wall is 16 feet wide and is lit now by 16 GE Chroma 50 T12 bulbs in four 4-foot fluorescent fixtures without diffusers (bare bulbs). They are rated at 2250 lumens. Total lumens 36000 and the light is very even. The D50 5000K T8 LED Tube Lights for Color Matching are rated on your website at 1800 lumens, which would be a total of 28800 lumens. My question is how would the lighting effect for judging the prints compare? Is 2250 vs 1800 lumens a true measure of the light output? 

We can confirm that the lumens listed on the product pages are a measurement of the total light being output in all directions by the light source. 

​While the quality and accuracy of the light output are measured in CRI and other metrics, you may find that the lower overall lumens may result in the reduced total illumination of your installation area.

As an alternative, we might recommend increasing the quantity of T8 LED Tube Lights by using additional fixtures in order to meet your illumination target. 

Further, it might be helpful to know that our T8 LED Tube Light products are not compatible with the ballasts within T12 fixtures. 

In the event that you install our products within the T12 fixtures, we recommend bypassing the ballast to utilize a direct wire configuration as illustrated within our product user guide. Please note that use with incompatible ballasts will cause damage to the hardware, and will void the warranty. 

Do you sell any fixtures suitable for residential or commercial light use?

Do you sell any fixtures suitable for residential or light commercial use (not troffer lights)? Or do we need to roll our own with the LED strips? Also, are your LED strips and/or your 4' LED tubes available for purchase in California? Are the restrictions just on the A19 bulbs, or is it on everything? 

While we unfortunately do not sell integrated residential fixtures at the moment. We apologize!

Further, we can confirm that our T8 LED Tube Lights and LED Strip Lights are eligible for shipping to California. The newest versions of our A19 lights have been updated to be compliant with the California energy requirements, as well. As such, please feel to place an order containing those items at any time. 

That being said, our new line of A21 bulbs, which feature doubled lumen output and slightly larger size, and currently not eligible for California shipping. 

My primary motivation in using your bulbs would be to keep my circadian rhythm in sync and ward off the seasonal affective disorder. I was wondering whether or not color temperature is a consideration in that context. I realize that 3000K is a more common residential color temperature, but I'm wondering if - for maximum "daylight" benefits - I should be looking at a 4000K or higher color temperature? Would the higher color temperatures, which more closely match daylight, be a better choice for my application?

Generally speaking, we find that the quality of the light tends to make more of an impact than the color temperature. That being said, installation areas requiring maximum visibility do benefit from the cooler color temperatures from 4000K-6500K. 

Based on the details provided, we might recommend trying the 4000K option and taking advantage of our 30-day return policy if they are not the right fit. Simply let us know, and we will gladly provide you with a prepaid return label for any unneeded items. 

High CRI Color Matching T8 Fixture for Dental Treatment

I need energy efficiency (over the life of the "bulb") to use in dental treatment where color matching is critical to customer service. Currently, using a color-corrected F8 fluorescent I see that the life of light varies as well as the warranty. Does wiring using the existing ballast versus 120V affect the CRI or life of the bulb or cost?

Based on the details provided, we would likely recommend our D50 5000K T8 LED Tube Lights for Color Matching. These lights are calibrated to the D50 standard for color-critical installations and offer a high CRI of 95+. 

It might be helpful to know that many fixtures utilize ballasts that are not compatible with LED power requirements, although they can be bypassed for full functionality. When used with incompatible ballasts, performance issues will likely be encountered that will dramatically shorten the product lifetime and will void the warranty. 

That being said, we can confirm that using direct wiring, if necessary, would not affect the cost or lifetime of the product compared to use with compatible ballasts. 

What is the difference between the NorthLux and the Centric Daylight? The Centric is rated for 50,000 hours and the NorthLux is 10,000. Is that correct? Both have the CRI of > 95 in the description line. I did not go through the spectrum analysis but I assume there is a difference there, but one lasting 5 times longer. Should I consider the Northlux in the area where color matching is done and the adjacent hallway the centric daylight both at 5K?  

The D50 5000K T8 LED Tube Lights for Color Matching have strict color maintenance requirements as defined by ISO 3664. As such, the 10,000 hours define the lifetime where the output aligns with ISO D50 compliance for color matching installations, whereas the 50,000 hours lifetime is in regards to general lighting.

Color Corrective LED Lamps for Graphic Application

I have a graphic that is using F32TSXLSPX50 HL lamps and would like to go LED. I would like an A/B direct wire lamp if it's available. 

Based on my review, the closest match to the F32TSXLSPX50 lights within our catalog would be the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, though the GE product provides 3000 lumens versus our T8 products which offer 1600 lumens. 

Before submitting your order, we strongly recommend ensuring that the ballasts within your pre-existing T8 fixtures are compatible with our lights. To this end, we suggest purchasing a 4-Pack of the product in the desired color temperature to ensure functionality before submitting the larger order. 

When these lights are used with incompatible ballasts, the product warranty will be void and functionality issues are likely to be encountered. If the ballasts are not compatible, we would recommend bypassing the ballast for the unencumbered functionality of the lights.

Flicker Free Dimmable Replacement LED Bulbs

One of our clients recently remodeled one of their office spaces and is having problems with flicker. Do you offer a dimmable, flicker-free LED replacement lamp? Have any of your products been tested for compatibility with Douglas Lighting Controls? 

Based on the details provided, it appears that you might be referring to our T8 LED Tube Light products, which are unfortunately not compatible with dimming technology. 

While we might normally recommend our Full Spectrum E26 BR30 LED Bulbs for recessed office lighting as an alternative, these products are not flicker-free. We do sincerely apologize for any impact that the above may have on your purchase planning. 

We continue to explore flicker-free options for our client's office space. Your website states that you have flicker free replacement bulbs. Do you have any other flicker free lighting options? We would like to replace these fixtures with flicker free fixtures. 

Based on the details provided, it appears that the closest match in our catalog would be the LED-Ready T8 Fixtures, which are compatible with our T8 LED Tube Lights. 

I have a couple of questions regarding the Centric Series Flicker Free- Non-Dimmable Power Supply.

Can this power supply be used to drive any led fixture or does it need to be used with your Ultra High CRI White Led strip? Used in combination with the Centric Series Flicker Free Non-Dimmable Power Supply are the Waveform CENTRIC HOME LED Strip Lights flicker-free? If so, could you please supply me with the spec sheet that shows the flicker index and percentage?

We can confirm that the CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip is compatible with the LED Strip Lights in our catalog of matching voltage.

We can also confirm that the CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip will afford connected LED Strip Lights with flicker-free output. Our available photometric reports can be found on our Photometric Test Reports page, which we hope is helpful for your installation planning.

While some of the tests list the flicker rate, many of those tests were performed using the FilmGrade™ DC Power Supply for LED Strip, which uses similar technology as our CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip. 

​

Can I use 2 tubes in a 4-tube fixture?

I just bought your “centric daylight, full spectrum, flicker-free T-8 in the 4-pack. I love the color of the light, but 4-tubes make it too bright. Is it ok to just use 2 tubes in the fixture? It’s the shop light style, covered with acrylic. It hangs a couple of inches below the ceiling, NOT recessed in the ceiling. We’ve had led tube lights from Lowe’s in it for 3 years but didn’t like the warm color of the tubes we had. So can we just install two tubes? 

Based on experience, we have found that most fluorescent fixtures allow for operation while only being partially filled with tube lights. 

As such, utilizing only two units within your four-bulb fixture should prove to be safe for operation. That being said, we would likely recommend looking for the light fixture user guide online, likely published on the manufacturer's website, to ensure functionality. 

LED Bulbs Recommendation for Art Studio Room

I am looking at lighting for an art studio room, size of approximately 11x12 ft. I think the bulbs I need are the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. For this size room, how many bulbs would be needed in a shop light fixture?

In the hopes of clarifying, it might be helpful to know that the NorthLux™ 95 CRI LED Shop Light Fixture ships with pre-installed LED lighting within, and would not require any bulbs to be installed for operation. 

Based on my review of our Lumen Estimation Calculator, it appears that ~10,379 lumens would be required to evenly illuminate your studio space for artwork creation. 

If the NorthLux™ 95 CRI LED Shop Light Fixture is indeed preferred, it appears that two to three shop light units would be able to meet that goal, each providing 4200 lumens. 

If a third-party shop light fixture were to be used, the Lumen Estimation Calculator recommends 13 units of the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, each providing 800 lumens. 

How do I configure these to hang them? Is there a fixture that holds 2 or 3 bulbs, or do I have to hang them individually?

The LED Shop Light fixture does not require any lightbulbs for functionality, as the light sources are installed within the product housing.

On the other hand, the BR30 bulbs can be used in most common residential fixtures, such as floor lamps and recessed ceiling lighting. 

In the hopes that it proves to be helpful, track lighting systems are often utilized for installing BR30 lightbulbs. Based on my review, several of those fixtures appear to be available from retailers such as The Home Depot and Lowe’s. 

Would the T8 LED bulb still work if the ballasts were to fail?

It states that the T8 tubs can be installed with existing ballasts. If the ballasts were to fail, would the bulb still work? 

Generally speaking, if a compatible ballast encounters a failure when connected, we would not expect any damage to occur. Instead, we believe that the T8 LED Tube Lights would shut off, rather than be affected by any surge from the ballasts. 

If that failure occurs, we recommend bypassing the ballast using a direct-wire configuration and removing the ballast from the fixture.

Recommended Lighting for Paint Booth

I have purchased some lights from you guys in the past and I’ve been very happy with the service and products and would like to continue patronizing you. That being said, I’m constructing a paint booth. What kind of lighting would you recommend? I want light from overhead as well as from the sides so I have really good 365-degree lighting around every project. 

In the interim, we might recommend installing our LED strip light products on the cornices of each wall within the 45° corner mounting channels for evenly distributed output throughout the booth. That said, this advice may change depending on the dimensions provided for the installation area. 

FYI, it’s a paint booth. It’s roughly 10’ wide x 6’ deep and 8’ high. I may make it fully enclosed, but for now, and for the sake of simplicity, let’s say it has an open face. 

Based on my review of the Lumen Estimation Calculator, it appears that the 10x6x8’ area would be evenly illuminated for fine manufacturing and detail purposes with 6,038 lumens. This lumen target could be reached by using four units of our T8 LED Tube Lights or 14 ft of LED Strip Lights. 

From the photo that you provided, it appears that the paint booth has two openings for T8 fixtures. If it does, we might recommend our 5000K or 6500K NorthLux™ 95 CRI T8 LED Tube for Art & Studio products, which are calibrated for color accuracy. 

These T8 LED Tube Lights are also designed to be compatible with our newly launched LED Ready T8 LED Fixtures, which do not utilize ballasts that many retrofit fixtures use. For reference, older fixtures often utilize ballasts that are incompatible with the power requirements of LED technology.

As a secondary recommendation, one or two of the 16.4 ft (5 meters) reels of the 5000K (D50-calibrated) or 6500K (D65-calibrated) ABSOLUTE SERIES™ LED Flexible Strip could be utilized, which would be able to replicate natural daylight with a CRI of 99. 

We imagine that one or two reels could be installed upon the wall cornices of the paint booth within the 45° corner aluminum channels for even light distribution. 

We have attached a few LayoutMaps below, which illustrate the many configuration options that are possible with the aforementioned LED Strip Lights. We do hope these are useful for your installation planning.

Human-Centric LED Lighting for Windowless Office

I work in a windowless office and am considering buying lighting from you. Would I buy the long strip bulbs for the ceiling lights? Or would I buy a floor lamp and bulbs? I've been looking at daylight-simulating desk lamps but they look too big for my desk. I have autoimmune and other health issues and already have the diet dialed, hoping to hit from all angles whilst still having to be employed full-time. 

 As far as your question of whether to go with ceiling lights or floor lamps + bulbs, we think both options would work well, and it would ultimately be up to you and your preferences for how and where to install the lights.

Starting with the floor lamp + bulb option, we think this would be the easiest and simplest setup, which wouldn't require any electrical work. Our A19 and A21 lamps are classic screw-in bulbs, so all you would need to do is purchase the floor lamp fixture of your choice and then install our lamps. If your office space is rented, the floor lamp would be portable and you would be able to take the lamp setup with you to any future location as well.

Ceiling lights will be a bit more complicated, as you will need to do some electrical work to get the fixtures wired up. One method would be to purchase our T8 lamps and install them in our T8 fixture. The advantage here would be that the light fixture will be ceiling-mounted, so it won't take up any floor space at all. Additionally, if the fixture is positioned above your workspace, this may allow you to have more direct and evenly distributed lighting (as opposed to a floor lamp in just one corner of the room).

Another option that might be a compromise between the two would be our T5 linear fixtures. These fixtures can be screw-mounted or magnet-mounted onto a variety of surfaces. This might give you both the flexibility of a semi-permanent installation while keeping the fixtures away from the floor.

All of these options offer flicker-free light output and provide full spectrum light, so they should all be a great fit for your needs; as mentioned it will ultimately come down to your personal preferences as far as installation method and location are concerned.

Lighting Option for Basement Painting Studio

I am trying to improve my basement painting studio lighting, and your brand came highly recommended. I am leaning towards 5000K and would like something flicker-free, ideally. I am trying to decide if I should get the Northlux bulbs or the Centric Daylight full spectrum bulbs for my inset ceiling cans. Can you explain the difference between the two for me? I also need to get some supplementary lights as tubes or something similar that don’t drop too far down from the ceiling.

We can confirm that the CENTRIC DAYLIGHT and NorthLux A19 bulbs are identical products that are provided with unique landing pages for marketing purposes, as can be noted by the shared part numbers. As such, identical output can be expected from each product, and we do sincerely apologize for any confusion this may have caused. 

For the ceiling tube lights, you may be interested in our NorthLux™ 95 CRI T8 LED Tube for Art & Studio, which is designed to be compatible with our LED Ready T8 Fixtures. 

As a further option, the NorthLux™ 95 CRI T5 LED Linear Light Fixtures are integrated lighting units that can be easily installed on different surfaces for convenient lighting adjustment. 

Can you recommend a light fixture for T8 LED Tube?

I am interested in your NorthLux T8 LED Tube for my Painting studio. Will you recommend a light fixture to purchase for This? 'My room is 16' x 27', Ceiling height is 13'. I am also interested in adding track lighting and using your bulbs. Any recommendations on where to buy the track lights? This is a new construction. 

While we do not have any specific third-party options to recommend, you may be interested in our LED Ready T8 Fixtures, which are designed to be compatible with our T8 LED lamps. 

We would recommend contacting an electrician to confirm that these fixtures are compliant with local zoning laws regarding new construction. Many regions have specific rules for the fixtures in new construction, which an expert will likely be able to assist with.

If you were to use a third-party option, we would recommend checking to ensure that the fixtures contain ballasts that are compatible. And if they are not, those incompatible fixtures can be rewired for ballast bypass. 

For your track lighting system, we would recommend our 5000K or 6500K NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio products, which are able to provide full-spectrum light with a high CRI of 95+. While we do not have any track lighting fixtures to recommend, there appear to be several options available from Home Depot. 

Are the NorthLux T8 5000k LED bulbs dimmable?

We can confirm that our T8 LED Tube Lights are not compatible with dimmers. We apologize!

Florescent Tube Replacement for Phillips F30T12/CW/RS 30-att

Could you please recommend a replacement for my lights? The bulb is a Phillips F30T12/CW/RS 30-watt. I'm not sure if there's a suitable replacement, or if I should replace the fixture entirely- in any case, I could use some product recommendations. 

Based on my review of the Phillips F30T12/CW/RS, it, unfortunately, appears that we do not have any compatible 36” T12 alternatives available. 

Currently, our catalog contains 48” T5 and T8 LED Tube Lights, which would not be compatible with any 36” T12 fixtures. We do sincerely apologize for any impact this may have on your purchase planning. 

As an alternative, you may be interested in our 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are compatible with our line of LED-Ready T8 Fixtures. Unlike older fluorescent fixtures, our line of T8 fixtures does not contain the types of ballasts that are often incompatible with LED power requirements. 

I have a maximum width of 47", which I think will be just a touch too short for the waveform fixtures. Is there a recommended third-party fixture I could use? If not, what's the next option- may be strips? I'm not sure which components I would need. I have two of these single-bulb fluorescent fixtures in a roughly 47x47" box.

Based on the details provided, it seems as though the preexisting fixture would not accommodate the 48" T8 LED Tube Lights. 

We can confirm that our T8 LED Tube Lights can function within any T8 fixture, though they may not be compatible with the ballasts that are often found in those older fixtures. These ballasts were meant to regulate the voltage for fluorescent tube operation in ways that our LED technology is not always compatible with. 

If the fixtures are confirmed to contain incompatible ballasts, these fixtures can be rewired to bypass the ballast to allow for full LED functionality and operation.

If you would prefer to retrofit the fixture to utilize the LED Strip Lights, you might be able to rewire it to utilize a compatible TRIAC Dimmable Power Supply for LED Strip. ​

Is there a minimum distance between the high CRI fluorescent bulb and the work surface?

Is there a minimum distance between the high CRI fluorescent bulb and the work surface? Will your fluorescent bulbs work in an existing dimmable fluorescent fixture?

Generally speaking, we do not advise any particular minimum distance between the light source and the target. Though we can confirm that the overall lux will reduce the further the light source is from the work surface due to dispersion. 

Unfortunately, our T8 LED Tube Lights are not compatible with dimmable fixtures, and we do apologize for any impact this may have on your purchase planning. 

As alternatives that are dimmable, you may be interested in our LED Strip Lights such as the 5000K CENTRIC DAYLIGHT™ LED Strip Lights and 5000K ABSOLUTE SERIES™ LED Flexible Strip.

Lighting Recommendation for Painting Studio

I’m interested in purchasing strip or bulb LED tube lights and fixtures from you— something that can light a 400 sq foot space w only a glass garage door as the source of daylight. I hope to find something in the 4500k range, with a high CRI. 

As a primary recommendation, you may be interested in our FilmGrade™ HYBRID LED Strip Lights, which can be calibrated to achieve any color temperature between 3200K and 6500K. 

For an easier installation that would require less wiring, you might be interested in our 4000K or 5000K options, such as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are designed to be compatible with our LED-Ready T8 Fixtures. 

You might also be interested in our CENTRIC DAYLIGHT™ 95 CRI LED Shop Light Fixture, which is designed for easy installation using the included hook and chain. This integrated fixture has been very popular with artists who utilize garages or other areas as studio spaces, due to the easy installation. 

Are any or all of these lights dimmable?

The products that we shared are unfortunately not dimmable. If dimmable products are preferable, we might alternatively recommend the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, or an installation that utilizes our LED Strip Lights. 

The LED Strip Lights can be mounted to ceiling or other surfaces by using the Aluminum Channel for LED Flex Strip, and powered using either in-wall power supplies or standard DC power. These products can also be controlled using the majority of standard in-wall dimmers, such as Lutron and others. 

If it proves to be helpful, we have attached a few LayoutMap links below which illustrate LED Strip Light installation options. Each diagram contains installation descriptions, as well as links to each of the recommended connecters and power supplies. 

LayoutMaps™ - LED Strip Light Layout 3001-1A

LayoutMaps™ - LED Strip Light Layout 3001-1B

LayoutMaps™ - LED Strip Light Layout 3002_2B

I’d like to know if you have a tube light structure that’s LED and also dimmable. Do the strips work in the first hanging fixture you sent?

Unfortunately, we do not have any fixtures which are flicker-free and dimmable at this time. We do sincerely apologize for any impact this may have on your purchasing plans. 

As a further note, the LED Shop Light fixtures shared in my initial reply are designed with pre-attached LED lighting products within. As such, no additional lighting products are required for operation. 

Are the LED shop light fixtures flicker free? Space is a total of 400 sq ft. Could the fixture be hung upside down so that it bounces off the ceiling as opposed to being hung as overhead lights?

We can confirm that the LED Shop Light Fixtures are indeed flicker-free.

While these fixtures could be installed in such a fashion that they shine directly upwards for indirect lighting, they are designed to be hung from the included hook and chain. 

Based on the dimensions provided, it appears that the space would be evenly illuminated for artwork creation with 31,451 lumens. This target could be reached with seven of the LED Shop Light fixtures, which each output 4,200 lumens. 

As an alternative, the target could also be reached using 18 units of the T8 LED Tube Light products, which are designed to be compatible with our LED Ready T8 Fixtures. 

Do you have overhead mountable fixtures/bulbs for art studio lighting?

I’m looking for overhead mountable fixtures/bulbs to light my 600-square-foot studio space. I’m looking for full spectrum, daylight, bulbs. What do you recommend? 

As a primary recommendation for art studio lighting, we would recommend our LED-Ready T8 Tube Light Fixtures and NorthLux™ 95 CRI T8 LED Tube for Art & Studio. These products are available in the most common color temperatures for artwork spaces (5000K & 6500K) and offer full spectrum output. 

If you would prefer to utilize fixtures that would not require hardwiring, we might alternatively recommend the NorthLux™ 95 CRI LED Shop Light Fixture, which can be easily installed from ceilings using the included chain and hook. 

For lighting installations where a mobile light source would be beneficial, you may also be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixture, which can be attached to different mounting surfaces using the included clips and magnets while offering the same high-quality light output as the above products. 

T8 LED Light Fixture for Commercial Kitchen Application

For a new commercial kitchen application, can you recommend the proper/best fixture for your T8 4K tubes? 

We usually recommend the LED-Ready T8 Tube Light Fixtures for use with our T8 LED Tube Lights. Unlike other T8 fixtures which often contain ballasts that are incompatible with LED power requirements, these items are designed for plug-and-play operation. 

For any new construction, we recommend getting in touch with a local expert who would be able to inform you of any electrical compliance issues that might arise from using these products before installation, due to the variation in local and regional electrical codes. 

Ceiling Mount Lights Bird Room Lighting

We are in the process of building a new 18'X23' interior bird room for our sanctuary, and I am looking for ceiling mount lighting that is appropriate for our parrot flock. After researching your site, I am looking to purchase four (4) LED Ready T8 tube fixtures, and eight (8) Centric Daylight 6500k flicker-free bulbs - and I want to be sure what I am purchasing is compatible with my needs. 

Based on our Lumen Estimation Calculator, we have received a recommendation of 14,336 lumens for the 18’ x 23’ space, which can be accomplished with eight units of our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. As each T8 LED Tube Light provides 1800 lumens, it would appear that the item quantities listed in your email can provide sufficient illumination to your bird room. 

Will the matching driver LD20W-36-C045 be compatible with D50 5000K T8 LED Tube Lights?

I am replacing bulbs that require "Matching Driver LD20W-36-C0450" Will this work?

Based on our review, it does not appear that the LD20W-36-C0450 ballast model that was shared is not among our list of compatible ballasts. When fixtures with incompatible ballasts are used with our T8 products, they will void the warranty and likely encounter early product failure.

That being said, it might be helpful to know that our T8 LED Tube Lights can be installed into fixtures by bypassing the ballast, thereby allowing for full operation. We have prepared a set of instructions for bypassing the ballasts within fluorescent fixtures, which can be found within the T8 LED Tube Light installation guide. 

Flicker-free T8 LED Tube Lights

I'm trying to figure out a few lighting questions about how to get non-flicker LEDs- tube lights, ceiling fixtures, and vanity. I can't tell from your tube lights if they are non-flickers. 

We are happy to confirm that all of the T8 LED Tube Lights products in our catalog offer flicker-free light output. 

Can you explain to me how to connect the tube lights without a fluorescent ballast, for them to be flicker-free? They are not on a dimmer.

My fixtures have slots for 4 tubes, but I'd like to only use 2 tube lights in each. The fixture allows for a very diffuse light so having fewer tubes just means less brightness, not weird gaps. Is that possible with your tube lights?

Do you sell T3, 90+ CRI, and flicker-free bulbs? I couldn't find any on your site. If you don't, can you point me to somewhere that does?

For the ceiling lights, I'm looking for E26 dimmable and flicker-free, 95 CRI. Some 2700, some 3000, some 4000

I'm considering this integrated LED fan&light fixture that doesn't give me specs on the integrated led, so I'm wary. It's the first time I've considered a fixture like this, and it looks neat but I don't want to end up with flicker and low CRI, but I have no way of telling. Are there any fixture makers of integrated LEDs that you know of that incorporate high CRI and are flicker-free?

We have prepared a set of instructions for bypassing the ballasts within fluorescent fixtures, which can be found within the T8 LED Tube Light installation guide. 

Unfortunately, we do not currently sell T3 light products, and we do apologize for any impact this might have on your purchase planning. That being said, a few options appear to be available from Home Depot and other marketplaces, based on my brief search. 

Based on the fixture description provided, it appears that our T8 LED tube Lights should function properly within the fixture, so long as the ballast has been bypassed if necessary. Most fluorescent fixtures that we are familiar with allow for operation even if not all T8 spaces are utilized. 

For your ceiling lights, we would likely recommend our CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs, which are available in the 2700K, 3000K, and 4000K color temperature options. 

We are not aware of any specialty lighting fixture makers who specialize in flicker-free high CRI light output. Those types of fixtures are generally outside of our expertise, and we do apologize. 

8-ft fluorescent LED Tubes Replacement for Art Studio

I am an artist so I'm happy to learn about your products for use in my art studio. I have read quite a bit about your NorthLux LED products but I'm still not sure how many fixtures I would need to purchase to replace what I now have. My current setup is three 8ft fluorescent fixtures installed end to end equalling a 24 ft run. Each fixture holds two tubes. I have 6 fluorescent tubes spanning 24 feet installed on my art studio ceiling. I am looking at your Northlux 95 CRI LED 4 ft Shop Light fixture.

In order to adequately replace the fluorescent fixtures, it might be helpful to know what the listed lumen output of each existing tube light is. 

With that information available, we can easily recommend a quantity of LED Shop Light Fixtures in order to match that lumen output to provide your studio with adequate illumination. 

For example, four fluorescent tubes which output 2000 lumens each would be easily replaced with two NorthLux™ 95 CRI LED Shop Light Fixtures, which each output 4200 lumens. 

High CRI LED Lights for Art Studio

What is most economical for lighting 350 sq ft studio with students working and 8.5' ceilings?

We would likely recommend our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio or NorthLux™ 95 CRI T8 LED Tube for Art & Studio products, which are designed to provide high-CRI output for studio spaces and artwork creation. 

Full Spectrum 2x4 Office Lighting for Drop Ceiling

I need to speak to someone about full spectrum lighting for an office to fit in a 2x4 ceiling grid.

While we do not currently have any direct 2X4 recessed office light product matches in our catalog, you might alternatively be interested in our LED Ready T8 Fixtures and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights for your installation. Our T8 LED Tube Lights offer a high CRI of 95+ and are available in the 4000K color temperature options most commonly recommended for office lighting. 

LED Light Option for Sculpture Studio

We are a group of sculptors and we're setting up a studio. The celling is about 18 feet overhead and there's one skylight off center. The space is rectangular. The sculptors are arranged around the model. Important consideration are ample light and no chatter or multiple cast shadows. We're thinkin to mimic the skylight by putting the lighting in the skylight box and have light that would yield similar to more or less obtain a similar quality. 

If that direct north-facing daylight is to be simulated for the studio space, we would recommend the 6500K color temperature option. The 5000K color point option can also be helpful for installations where a neutral daylight color is preferred. 

For an installation that would occupy the perimeter of a skylight, you might be interested in our 6500K FilmGrade™ WHITE LED Strip Lights, which can be easily mounted within aluminum channels and powered via in-wall LED drivers and dimmers. 

If integrated fixtures are preferable, you may alternatively be interested in our NorthLux™ 95 CRI LED Shop Light Fixtures, T8 LED Tube Lights or T8 Fixtures. That said, please note that these products are not dimmable, and may not be the ideal products for a studio space that requires adjustable light output. 

For your installation planning, we recommend inputting the dimensions of the space into our Lumen Estimation Calculator, which will provide you with a total lumen suggestion as well as product recommendations to meet the lumen goal. 

T8 LED Tube for Avian Lighting

I am trying to install full spectrum lighting for my Aviaries. I want to have LED tube lighting if possible.

While not specifically marketed for aviary installations, we would likely recommend our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, as they utilize the same technology and color temperature as our Avian Full Spectrum Lighting.

These products are also designed to be compatible with our newly launched LED-Ready T8 Fixtures, as well as fixtures using either compatible or incompatible ballasts.

Will the prismatic wrap on the fixture allow the full spectrum to come through? Or should I go with the one with the reflector?

While we can confirm that there is a slight reduction in light transmission through the prismatic lens (~10%), there would not be any change to the spectrum of light that passes through the prismatic lens. 

LED Lamps for Horticulture Algae Growth

I'm wanting to illuminate 6 research incubator cabinets for microalgae culture growth. Cabinets are 800mm x 670mm area x 670 high. Your PhotonPanels look almost ideal, but dimensions will lead to some dead space and we are trying to maximize uniformity of illumination across the cabinet. Do you have any capacity to custom-size panels? e.g 750 x 650? I am using this setup for laboratory research inside temperature-controlled incubators. I searched through more than a hundred different setups before selecting these parts from Waveform, so I hope that this review might benefit other scientists looking for LED equipment that actually belongs in a lab." 

Unfortunately, we cannot do custom LED panels at this time.

On the other hand, we do believe that our existing PhotonPanel with dimensions of 560 x 280 mm could be purposed to fit in your cabinets.

​While the configuration may be a bit awkward with the dead space you mention if the distance between the panels and the illumination target is 670 mm, the light distribution should actually be quite dispersed and there should not be any significant issues with uneven illumination.

​This is because the LEDs emit light at a 120-degree beam angle, which ensures that the light spreads out quite a bit as you increase the distance from the panel.

Custom Strip for Fluorescent Fixtures Replacement

I was wondering if it is feasible to create a custom strip array for a ceiling to replace fluorescent fixtures.

While we are unable to accommodate custom product fabrication at this time, we would be more than happy to tell you more about our currently available catalog of products.

For example, you might alternatively be interested in our FilmGrade™ FiveSpect 5-in-1 LED Strip Lights or LED-Ready T8 Tube Light Fixtures, the latter of which are designed to utilize our LED T8 Tube Lights. 

Health LED Lighting Fixtures

What products do you have so I can evaluate their application in my remodeling? I have an electrician who can follow up to address specs/tech matters.

Our Full Spectrum E26 BR30 LED Bulbs are a great option for recessed lighting, though they are not flicker-free as our A19 and A21 LED bulbs are. 

While we do not sell integrated recessed light fixtures, you might alternatively be interested in our ceiling-mounted LED-Ready T8 Tube Light Fixtures, which are designed to be compatible with our flicker-free CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. 

T8 LED Tube Light with High CRI for Dental Office

I'm looking to replace our current fluorescent T8s with LED T8s (high CRI). Noticed you have a few types of T8s that appear to fit our needs, however, I'm wondering which model you would recommend for a dental office where color matching and lighting comfort are important. 

For installations where color matching is a priority, we generally recommend the D50 5000K T8 LED Tube Lights for Color Matching. We also recommend checking to ensure that the ballasts within the preexisting T8 light fixtures are compatible, to ensure optimal functionality. 

Based on what I read on the spec sheet, is it correct to assume that I can just install the D50 tubes into the fixtures without removing the ballast and have the option to rewire in the future (remove ballast) if I choose to? If so, that would be awesome because it would allow us to try out the D50 tubes and, if all goes well, we can schedule a day for the electrician to come in to remove the ballasts from all our fixtures and rewire. All our fixtures currently have electronic ballasts (Philips Advance ICN-4P32-N and ICN2P32-N). Are these ballasts compatible?

We are happy to confirm that the fixtures can be rewired for ballast bypass if the lamps are incompatible with the ballasts within. 

Based on our review of our compatibility list, it does appear that our T8 lamps are compatible with the PHILIPS-ADVANCE ICN-2P32-N ballasts, though we do not see the ICN-4P32-N model listed. 

Table Tennis Court Lighting Solution

What would you recommend to light a pro-level table tennis court? It is 20ft X 40ft with a 20ft ceiling height. Optimum clear resolution of the ball is paramount. It is traveling 40 to as much as 70 miles per hour and struck every 1/3 to 1/2 second. 

Based on the details provided, we would recommend one of our flicker-free products for the uniform lighting of the ball and court during play and video capture. 

If you would like to let us know more details about the preferred lighting fixtures for your court, as well as let us know whether the court is planned to be indoors or outdoors, we would be happy to provide you with a few product recommendations. 

In the interim, our Lumen Estimation Calculator might be helpful for your installation planning. 

Will your T8 tubes operate in a single-ended fixture?

We are happy to confirm that our T8 LED Tube Lights can be installed within single-ended and double-ended fixtures. That said, we do encourage customers to ensure that the fixtures contain compatible ballasts to ensure full functionality, though the fixtures can also be installed via ballast bypass.

​As an alternative, you may also be interested in our recently launched LED-ready T8 Tube Light Fixtures. These fixtures are compatible with our T8 LED lights and do not require any rewiring or ballast considerations. 

We have attached a link to the product installation guide below, which includes details regards each installation method.

T8 LED Tube Light Installation Guide

Can I use your products with 230V and 50Hz inputs?

Do all of your products support 230V and 50Hz? I live in a country where the gride provides ~220-240V, 50Hz. Can I use your products with these inputs?

We can confirm that many of our products, such as the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb, are compatible with global voltage standards (AC90-240V/50-60Hz). That said, we recommend ensuring that the products utilize a compatible base before ordering. 

The voltage compatibility of each product should be listed within the product description as well as within the specification sheets available on each product page.

I decided to upgrade my home setup with 6500K lighting with +90 CRI, so if you could please help me choose the right light bulb or light tube that can fit the voltage and frequency I have, I would be grateful. Additionally, do you sell lighting fixtures for your products? If not can you recommend me a good brand I can purchase it online.

You might be interested in the 6500K NorthLux™ 95 CRI T5 LED Linear Light Fixtures, which are compatible with 120 – 277V AC 50-60 Hz. That said, an adapter for local DC plug standards might be required for your usage. 

As a ceiling-mounted T8 LED Tube Light option, we recently launched the LED Ready T8 Fixtures which are also compatible with our 6500K T8 LED Tube Lights and 120 – 277V AC 50-60 Hz input voltage.

T8 LED Tube Compatible Fixtures

I’ve been debating buying a shop hood/ballast locally and putting your lights in them, but when I look at the light ballasts that are confirmed to work and it just lists the ballast’s technical number. What I need is a brand name for the hood so that when I go to Costco/Lowe’s/etc I know which ones to buy.

If you hope to find a compatible fixture for our T8 lights, you might be interested in our LED-Ready T8 Tube Light Fixtures. 

These products are designed without ballasts so that the T8 LED lights are fully compatible without requiring a ballast bypass or the confirmation of compatible ballast models within the fixtures. 

Would the LED Ready T8 Tube Light Fixtures work with other T8 tube lights or only yours? They are pretty expensive since they don’t include lights, that's why I was looking for shop hoods/ballasts that were from somewhere else to combine with your lights. Do you know any brands that would work the T8 LED Tube lights? 

Also, can you tell me a bit about the prismatic lens on that Tube Light fixture-it is giving me institutional vibes but having diffused/scattered bright light would be nice?

We're happy to confirm that our T8 LED Fixtures are compatible with third-party T8 lamps, so long as they are single-ended direct wire lamps. 

This is because not all third-party T8 lamps offer 3-in-1 compatibility. That said, we, unfortunately, do not have any third-party options that we could recommend at this time. 

We can also confirm that the diffusor cover can prevent hot spots by evenly dispersing the light output. These diffusers can be helpful for installations where even output is required.

Studio Lighting 1962 Home with Unfinished Basement

Could you please calculate and advise on which fixtures to light the 21’ x 26’ x 8 high basements with exposed rafters? I would like to use this space as my art studio. There is a single very small glass block window 15” x 20”. 

By using the lumen estimation calculator, we received a similar 42,931 lumen estimate recommendation for your space based on the dimensions. 

It might also be helpful to know that the referenced NorthLux™ 95 CRI T5 LED Linear Light Fixtures are not usually installed as ceiling lighting due to their usage of DC power via wall plug for operation. 

If in-wall power and wall switches are preferred for the basement lights, you might alternatively be interested in our LED Ready T8 LED Fixtures and NorthLux™ 95 CRI T8 LED Tube for Art & Studio. By my estimation, the 42,931 lumen suggestion can be reached with 24 of the aforementioned T8 lamps. 

Do you have a 4-inch T12 LED Tube Light?

We have a drop ceiling that has 9' x 4’. Fixtures each containing 2 40-watt fluorescent bulbs (18 total needed). I’d like to get the ones that are soft white (a step down from the brightest) powered at both ends and bypass the ballast.

We would recommend our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. The closest color temperature to ‘soft white’ (usually 2700K-3000K) available is the 4000K option. 

If the ballast within the fixture has not yet been bypassed, we have attached a link to an installation guide below, which illustrates the process.

T8 LED Tube Light Installation Guide

Which LED Light Color Temperature Should I Choose?

If you would like to make a direct comparison ahead of submitting the larger T8 order, you might be interested in purchasing some of our A19 bulbs in those color temperatures and using our 30-day return policy once you’ve determined which color point is best for your space.

T8 LED Tube Light for Filming

I'm looking for a large order of T8 tubes I can place into existing fixtures for filming. The film lighting tab doesn't recommend premade tube choices. I just wanted to confirm, would you recommend the NorthLux tubes for such a use rather than the Centric Daylight ones? 

As the Northlux and Centric T8 LED Tube Lights are from the same product family, the only difference can be found in the available color temperatures. Beyond that, identical performance and output can be expected from each. 

For your installation, it might also be helpful to know that some fluorescent fixtures utilize ballasts that are not always compatible with LED technology. As such, we would recommend checking to ensure that your ballasts are compatible. If not, these lights can also be installed in ways that bypass the ballasts entirely. 

​We also have our own LED-Ready T8 LED Fixtures, which might be of interest. 

Just looking to buy now and noticed that the lights are listed as non-dimmable. Will they not dim at all or is there the possibility to dim a little depending on the power supply as is often the case with other LEDs?

We can confirm that the T8 Tube Lights and T8 LED Fixtures are not dimmable. 

When these products are provided with less input voltage than they are designed to expect, they can encounter performance issues that can damage the internal components. 

​This is different than the LED Strip Lights, which utilize a dimmer between the power supply and product, whereas in-wall dimmers adjust the voltage provided to the internal power supply of the fixture and lights.

Is the NorthLux 95 CRI LED Shop Light Fixture Dimmable?

Is this fixture dimmable? Can it be hard-wired, rather than plug? Can they be flush mounted to the ceiling, like at a junction box? 

We can confirm that as the LED Shop Light fixture is intended for DC-plug power and wall hanging via the included hook and chain, it, unfortunately, is not compatible with flush mounting and hard-wiring. 

Additionally, this product is not dimmable, and we do apologize for any impact this might have on your purchasing process. 

That said, you might also be interested in our new LED-Ready T8 Fixtures, which are designed for both direct wiring and flush-mounting to ceilings. Further, these lights are designed to be compatible with our High CRI T8 LED Tube Lights.

As an additional benefit, the T8 LED Tube Lights can be easily replaced in the event of a malfunction, whereas the LED Strip Lights are affixed to the Shop Light Fixtures. 

Replacement T8 LED Tube for T12 Fluorescents Fixture

I'm interested in the NorthLux T8 95 CRI LED tubes. Am I understanding correctly that these can be used in fixtures that now have T12 fluorescent bulbs, as long as the ballast in the fixtures is removed? Is there any advantage to replacing the fixtures?

We can confirm that our T8 LED Tube Light products are compatible with T12 fixtures, so long as the ballast within the fixture has been bypassed. We have provided a link to the installation guide below, which contains several ballast-bypass options. 

Generally speaking, so long as the fixture can utilize compatible line voltage, we would not foresee any non-cosmetic advantages to replacing the light fixture. 

Flicker-Free T8 LED Tube Installation Guide

Does your NorthLux Shop Light Fixture support flush mounting and hard wiring?

Does your Northlux shop light support flush mounting and hard wiring? Is there an adapter that allows daisy chaining by directly connecting one unit to an immediately adjacent (touching) unit instead of by a cable that would effectively force some separation? 

We can confirm that the LED Shop Light fixtures are designed for hanging installations, and are not designed to support flush-mounting or hard-wiring. 

​Additionally, we do not have connecter accessories available that might allow for directly interlocked the shop lights, and we do apologize for any impact this might have on your purchase planning. 

As an alternative, you might be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixtures, which are designed for interlocking, daisy-chained power, and can be flush-mounted using the included screws or magnet brackets. 

Do you have daisy chain cables longer than 12”? (Up to 20’)? Do you have adapters to hardwire the units?

We currently do not have longer daisy chain cords available, though it might be helpful to know that standard three-prong plug extension cords are compatible with the daisy-chaining of the LED Shop Light Fixtures. 

Additionally, we unfortunately do not sell adapters or kits for hardwiring the LED Shop Light Fixtures. We apologize!

As an alternative, you might be interested in our LED Ready T8 LED Fixtures, which are designed for ceiling mounting and direct-wire connection. These fixtures are designed to be compatible with T8 LED Tube lights, which have the benefit of being easy to replace in the event of a malfunction, compared to the shop light fixtures which utilize affixed, non-replaceable lights. 

Best LED Tube Lighting for Interior Design Studio

I need lights to go above work tables for selecting paint and fabrics. Please advise 4 ft fixtures.

Based on the details provided, we recommend the 5000K NorthLux™ 95 CRI T8 LED Tube for Art & Studio products, as it is D50 calibrated for color matching and proof viewing. 

That said, you may also be interested in the 6500K option (calibrated for D65) if you hope to match colors based on natural daylight. 

In case it proves to be helpful, I have attached articles comparing the two options below. 

What is D50 for graphic arts & printing?

What is D65 and what is it used for?

Choosing Proper Lights for Home Reno Project

I am doing a home reno project that is including renovating two bathrooms and the kitchen. Could you help me figure out which of your products is right for me and let me know product availability? Full-spectrum, flicker-free, low EMF are my desired features for lighting.

Ceiling fixtures: I will have two of these installed (one already is): Sputnik chandelier

For the Sputnik chandelier, we would recommend the dimmable 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. The 3000K color temperature is the most common option for kitchens and dining areas. 

Under-cabinet task lighting (four zones): I'm looking for a permanent power supply installation of strip lighting instead of each zone lighting having to take up a wall plug. 

For the under-cabinet kitchen zones, I would recommend the 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential with the Aluminum Channel for LED Flex Strip and TRIAC dimmable power supply. 

Please note that these 12V LED strip light products have a maximum combined length of 16.4 feet, meaning that connected lengths greater than that will experience diminished output.

As such, if the under-cabinet zones are to utilize greater than 16.4 feet of product, we would recommend utilizing a second dedicated reel of LED strip lights paired with a dedicated dimmable power supply. 

As can be noted in the below LayoutMap, multiple power supplies, and LED strip lights can be connected to the same dimmer. Our power supplies are also compatible with smart home dimmers. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

If you would like to provide us with a rough layout of the under-cabinet installation areas, I would be more than happy to provide a recommended parts list and order quantity. 

High hats: My licensed electrician is supplying these. He said he can choose styles that take bulbs instead of LED light covers, but he knows nothing about flicker-free, full-spectrum lighting.

For dimmable lightbulbs that would be compatible with a partially or fully enclosed high-hat fixture, we would recommend the 3000K Ultra High 95 CRI A19 5W LED Filament Bulb. 

Bathrooms: I've gotten this wall fixture for both bathrooms: Maxim Lighting Essentials 4-Light polished chrome bath vanity light.

Based on our review of the fixture, I would recommend the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, as it is suitable for enclosed fixtures as well as use in damp locations such as bathrooms. We usually recommend 2700K or 3000K for those areas. 

Garage: I currently have a ceiling fixture that uses florescent bulbs. 48". I don't spend a lot of time out there and am not sure I want to spend extra for specialty bulbs. 

For the garage fluorescent fixture, we would recommend our 5000K NorthLux™ 95 CRI T8 LED Tube for Art & Studio. Before purchase, we recommend checking to ensure that if a ballast is utilized within the fixtures, it is compatible with our LED tube lights. If not, these lights can also be installed using a ballast-bypass method. 

As a final note, please feel free to take advantage of our 30-day return policy if items within your purchase aren’t quite the right fit. For the LED strip lights, we are happy to accept them as returns so long as they have not been cut or altered. 

6500K LED Lighting for Dental Office Remodel

I'm interested in color correct 6500 Kelvin LED lighting for a dropdown ceiling in a 3000 sq ft dental office remodel.

In the interim, you may be interested in our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light, which is available in the 6500K color temperature and provides full-spectrum high CRI light output. 

You might also find value in our Lumen Estimation Calculator, which can provide recommend quantities of light products based on the dimensions of the office. 

Fluorescent Replacement for Office Space Lighting

We are moving offices, and I am searching for lighting to replace our current fluorescents. We are looking for human-centered lighting that will create a better work environment for our employees. The space needs lighting that totals 108,000 lumens. However, we already have purchased some hanging pendants that account for 24,000 lumens. As a result, we are looking for additional lighting to account for another 84,000 lumens. At this time, we are thinking that hanging linear lights would be the best option. I have looked at your Northlux Light Fixtures as an option. What would you recommend? Could you point me in the right direction for products and provide me with an estimate?

Though the NorthLux™ 95 CRI T5 LED Linear Light Fixtures are easily mountable and provide high-quality light, they are not usually used for office spaces as they are not dimmable, and require DC-plugs for power. 

These limitations can be detractors for customers who intend to connect the lights to utilize in-wall power, or for customers who want to be able to adjust the output using a wall dimmer or smart dimmer system. These same considerations are true for our NorthLux™ 95 CRI LED Shop Light Fixtures, which also rely on DC plugs. 

As an alternative, you might be interested in our NorthLux™ 95 CRI T8 LED Tube for Art & Studio, as they can be installed within T8 fixtures as well as easily replaced if the individual lights encounter any malfunction. 

​For an installation where utilizing dimming and in-wall power are preferred, we would recommend the 99 CRI ABSOLUTE SERIES™ LED Flexible Strip Lights. These products can be ceiling-mounted within channels and are able to offer our highest quality of light output. 

Do you have a 48-inch bulb for standard 4-ft LED fixtures?

Do you make a 48-inch bulb that I can use in standard four-foot LED fixtures for my birds? 

Based on the details provided, we would recommend our 6500K NorthLux™ 95 CRI T8 LED Tube for Art & Studio, which is designed to fit F32T8 4-ft (48 inches) fluorescent lamps. 

For reference, the 6500K option is the same color temperature as found in our Avian line of products. Additionally, it might be helpful to ensure that the T8 fixtures to be utilized are compatible. 

Though many older units utilized ballasts that are not compatible with the power requirements of LED products, those fixtures can be adjusted to accommodate our products through 'ballast bypass'. Instructions for this process can be found in the below installation guide. 

T8 LED Tube Light Installation Guide

PhotonTube vs FilmGrade Strips: Do the strips output a similar amount of photons?

I have a question regarding the output of the FilmGrade Strip in 6500K vs your T5 PhotonTube in 6500K. Do the strips output a similar amount of photons (par, ppf, or lumen) as the T5 Tube configuration? Are they the same diodes? 

We can confirm that the 4-ft PhotonTube™ T5HO LED Grow Light Tubes have an output of 48 umols/sec, which translates to 2087 lumens. This means that one 6500K T5HO Tube Light will have the same output as 4.63 feet of the 6500K FilmGrade™ WHITE LED Strip Lights (which output 450 lumens per foot). As such, the output will be fairly similar by length. 

We can confirm that the PhotonTube™ T5HO LED Grow Light Tubes utilize the 2835 LED size. 

In the event that they prove to be useful, we have attached links to both the 'Lumens to PPF' and 'PPF to Lumens' calculator tools from our website below. 

Convert PPF to Lumens - Online Calculator

How T8 LED tube light products are compatible with many fluorescent fixtures?

Reading a lot about r&r fluorescent 4' bulbs. I have some confusing thoughts, where and how is 120V AC step down to a DC or small AC voltage? Also, is there a better connection than the " tombstone" type? I have a constant problem with them and that may be the main reason to switch to LED. 

We are happy to confirm that our T8 LED tube light products are compatible with many fluorescent fixtures due to the internal hardware which converts the electricity from AC to DC. 

As voltage drop is often caused by large distances between the power supply and light product, or alternatively due to the improper gauge of wiring being used, we would not assume that our T8 LED Tube Lights would be affected by them when installed within a compatible fixture. 

Additionally, we can confirm that we have not heard of any drawbacks to the tombstone connector versus other options. For better insight regarding the fluorescent tube light connector options, we would recommend reaching out to a lighting specialist or hardware store. In the interim, we can confirm that our T8 LED tube lights only utilize the tombstone connectors. 

Do you have fixtures that would use your LED Strip Lights?

I am remodeling a dental office. I am looking for options for general lighting in the treatment areas. The rooms have drywall ceilings that are 7 feet 8 in. I would like to have a 1' x 4'' LED panel that has CRI of 95 and 5000K temp. Your LED options seem to meet that requirement, but I'm having trouble finding a fixture that would work. It would need to be surface mounted in this situation. Do you know of a fixture that might work that uses your LEDs?

As we currently do not have LED panel products available in our catalog, you might alternatively be interested in our T8 LED tube lights which feature the same LED technology. 

You may also consider our LED-Ready T8 Fixtures, which are designed to be ballast-free and LED-ready for office installations. 

Lighting Options for Photography and Reptile Habitat Needs

I'm currently researching lighting options for a home addition that's currently in process at our primary residence. This is essentially a shop that's 30x20, but CRI and overall brightness are critical. I'm a breeder of high-end Leopard geckos (reptiles), and accurate photography (color representation) is an absolute must. I can only assume that I should be targeting a CRI of 90 or higher. With my photography, I tend to err more on the side of daylight or cooler about Kelvin and have a strong distaste for what I would consider 'warm' lighting.

We are happy to confirm that we have several products available which could be a great match for your photography and reptile habitat needs. Further, we can also confirm that the vast majority of our products offer a CRI higher than 95. 

As a starting point, you may find value in our Lumen Estimation Calculator tool. By inputting the dimensions of the room including ceiling height, as well as selecting the primary use of the room, the tool can suggest a total lumen output and suggest the number of products required to meet the illumination goal. 

In the interim, we might recommend the NorthLux line of products, which are designed with photography and capture in mind. You may also be interested in our 99 CRI Absolute Series products, which offer D50 and D65 light that is virtually indistinguishable from full daylight. 

Dimmable and Flicker-free Lighting for Video/Photo Studio

I'm a videographer and I'm in the process of helping our contractor to convert an existing office space into several small video/photo studios as well as multi-person editing suite. 

Our needs are for the studio lighting to be daylight balanced (ideally 5600K), dimmable, and flicker free. 

1) Would this power supply allow flicker-free dimming using a standard wall dimmer from your dimmer compatibility list (e.g. LUTRON SCL-153PR-WH, LUTRON DVCL-153PR-WH) or would it require your FilmGrade Flicker-Free LED Dimmer?

2) Are your aluminum channels suitable for being suspended from a ceiling rather than directly mounted to a flat surface? If so, do you have any guidance on how that might be done? If not, are there any fixtures that you could recommend that are compatible to be fitted with your LED strips?

3) Finally, do you have any suggestions for how LED strips might be incorporated into a drop ceiling? 

We are happy to confirm that both of the referenced Lutron models have been tested as compatible with our power supplies. For a full list of compatible dimmers, please reference the document linked below. 

We can also confirm that we have not had any experience with suspending the aluminum channels from the ceiling as a lighting installation before. As such, we unfortunately might not have any helpful advice for this installation type. 

​As an alternative, you may be interested to know that our T8 LED tube lights feature the same LED technology as the LED strip lights. Further, we are introducing a line of LED-ready T8 fixtures that are designed for office and workspace installations.

We have also provided a link below to our Lumen Estimation Calculator tool, which can be helpful for determining the lumen requirements for different spaces.

Lighting Solution for Color Matching and Custom Picture Framing Presentations

I am seeking a solution for our color matching along with our custom picture framing presentation areas. I am looking for a lighting solution for two areas of concern. Number 1 is a color-matching room as I would call it. The size is 10 ft x 10 ft which currently has a 2 ft x 4 ft fluorescent lighting that would serve as a neutral light area. I would be color-proofing original Artwork to my calibrated monitor and my printed images. The second is two sales presentation tables for picture framing designs that I would like to place a fixture over so that we have a neutral color cast over this area. The tables are approx. 4ft x 8ft sections.

By entering the dimensions of the color matching room into our Lumen Estimation Calculator, we estimate that the area would be fully illuminated for artwork and capture by ~7,963 lumens. We entered 8 ft as the ceiling height in my process, though you will likely find value in adjusting this to receive a more accurate estimate. 

For this space, we would recommend 5-6 units of the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product. These T8 tube lights offer 1800 lumens per tube light, as well as a CRI of 95+. If the fluorescent fixtures being utilized contain ballasts, we would recommend checking our compatibility list to ensure compatibility. 

For the presentation tables, you may be interested in the 5000K or 6500K NorthLux™ 95 CRI LED Shop Light Fixture product, which offers 4500 lumens per unit and is easy to install utilizing the included chain and hook. 

As an alternative, you may also be interested in the ABSOLUTE SERIES™ LED Flexible Strip product, which has a CRI of 99, making them virtually indistinguishable from daylight. This item is available in both the D50 and D65 ISO standards and can be installed within ceiling-mounted channels, and paired with a wall dimmer via the in-wall TRIAC dimmable power supply. 

I have yet to progress further on this project and I am looking to expand my needs for this project. We have needed to reorganize the lighting area to a larger footprint 30’ x 26’ x 9’. I have attached a photo of the area and specifically the trusses that I hope to use to attach the lighting to. The trusses run the length of 30’ and there are 4 runs in total at 6’ apart. 

Since my main focus will be to properly evaluate a scanned piece of Artwork to what is printed the less color shift lighting brings the better. I look to your recommendation to best achieve this goal. Can you recommend a lighting package for this area?

For installations that require precise color accuracy, we usually recommend our D50 and D65 ABSOLUTE SERIES™ LED Flexible Strips. These products can offer a 99 CRI, and provide light output that is virtually indistinguishable from daylight. 

​As you will note from the review section of the above product page, several of our customers have found success in using this product for art production and photo capture. We certainly hope that this product is helpful for your installation as well! 

In the hopes that they prove to be helpful, we have attached the photometric reports for each version below:

D50 ABSOLUTE SERIES™ LED Flexible Strip 

D65 ABSOLUTE SERIES™ LED Flexible Strip 

Would you have some install photos to see how these would be installed? Would these just get attached to the trusses and left exposed or I have seen on your website there is a trim package but would the covers affect the light in any way?

Unfortunately, we do not have any installation photos readily available that we could share. We apologize!

We usually recommend installing the LED Strip Lights into channels, such as our flat Aluminum Channel for LED Flex Strips. 

​When installed within the channels, the light products can be easily adjusted or replaced if outages occur with more ease than if they were attached directly to trusses. These channels will also help to protect the LED light products from dust and residue that might cause operational issues in the future. 

The light covers will reduce the overall transmission by roughly ~10% as most polycarbonate diffusion panels will, though the color temperature and spectrum of output would not be expected to change.

8-ft T12 Fluorescent Replacement for Shop/Studio Lighting

I'm very interested in replacing the lighting in my shop/studio. I have 8' T12 fluorescent lighting that I replaced with LED, and they're hurting my eyes more than fluorescents do. I was told that 2700k and the high 90s or above CRI rating possible was best. I don't see an 8' replacement on your site, just 4ft. Is that correct? I'm feeling overwhelmed and confused with this project. Could you recommend lighting options for my shop with something as close to daylight as you have? Am I better off having rows of screw-in type bulbs everywhere or do you carry strip or tube lighting that you would recommend? 

First of all, I suspect that the eye strain you are experiencing may be the result of hidden flicker in the new LED lamps, rather than a color specification issue. Here is a video that explains how you would be able to detect this using an iPhone: https://www.youtube.com/watch?v=QTVjokUy2Dw

Since your fixtures are only able to accommodate 8 ft lamps, we, unfortunately, would not be able to utilize them with any of our lamps. Without having to replace the fixtures entirely, however, you may be able to use our NorthLux T5 linear fixtures as a retrofit solution (https://store.waveformlighting.com/products/northlux-95-cri-t5-led-linear-light-fixture).

​The T5 linear fixtures are available in 2-ft and 4-ft lengths and can be mounted inside existing fluorescent fixtures using the included magnet mounts. These could very well "replace" the 8 ft lamps without actually needing to use the same lamp sockets, and this could also allow you to repurpose your existing fixtures as housings for the new lamps.

​These are flicker-free, and have 95 CRI and 5000K / 6500K light output, ensuring excellent color accuracy that matches natural daylight.

I was actually just looking at those calculating how many it would require to at least match the lumen levels I have now. Great CRI rating, though I was looking more in the 3-400k (max) bulbs as anything higher than that is just too blue for me. I have an eye condition and no longer wear the proper contacts. 

It's a 3800 sq ft area so unfortunately it's going to require a number of lights to illuminate properly. 

Determining the total brightness needed is indeed a bit tricky, as sufficient brightness is very important for studio work, but having too much brightness could lead to potentially unpleasant glare effects as you've experienced. We offer a lumen calculator on our website here, which may be of interest: https://www.waveformlighting.com/lumen-calculator

Based on the 3800 square feet input, the calculator suggests approximately 150,000 lumens for your space if you are looking to reach a sufficient illumination level for studio work (80 footcandles). This would require approximately 85 of our 4-ft T5 lights to illuminate the entire space with sufficient brightness.

Of course, based on your personal preference, 80 footcandles may be too bright and intense. We could definitely cut this down to half, to 40 footcandles using 43 of the 4-ft T5 lamps, which is the generally recommended brightness level for a standard commercial or office space installation. 

What's the difference between the T-5 and T-8? Is that just a matter of what fixture you have? 

In addition, I also meant to ask if the daylight tube bulbs work differently than the non-daylight ones. I'm expecting to have to replace all the sockets as I have a variety of lights that would complicate things to match. I think it would be best to just replace them all and start off with matching sockets. Can I assume these plug into power directly as others do? Or do they need some sort of ballast?

The primary difference between the T8 lamps and the T5 fixtures is that the T8 lamps require a fixture to house them (typically traditional T8 fluorescent fixtures), while the T5 fixtures are an integrated LED fixture that does not require installation inside a fixture.

​Generally speaking, we would recommend the T8 lamps for customers who have an existing 4-ft T8 fluorescent fixture. You mentioned that you have 8-ft fixtures, which are unfortunately not compatible. As such, we would recommend foregoing the T8 lamps unless you had plans to reinstall new T8 fluorescent fixtures.

​The T5 fixtures, on the other hand, do not require a separate fixture and can be installed in virtually any location. A fluorescent ballast is not required, and the product can plug into any wall outlet or extension cord.

​Our daylight/non-daylight designations relate to color temperature and do not have any bearing on the installation configuration.

Sounds like T8's may fit the bill. I'm a fabricator, so if need be I can retrofit the 8ft fixtures or fabricate new ones with new sockets. Though purchasing T8 fixtures sounds best. I think we may still have some in storage actually. 

Sounds like a plan! As long as the sockets are spaced at the correct spacing to accommodate the 4-ft T8 tube lights, there shouldn't be any issues there. From a liability perspective, we do need to mention that the company's official recommendation is to only use fixtures designed specifically for 4-ft tube lights, but from an electrical standpoint there should not be any issues operating the 4-ft T8 lamps.

The "CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light" can be used with both shunted and non-shunted sockets. Please see below for the installation manual showing the various permissible wiring configurations:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

What's the highest wattage available? Is 1,800 lumens the brightest 4ft T8 you carry? My 8-footers are 110w @ 8,800k per bulb, with 4 in each bank. 

The only as well as the highest wattage available is 18 watts at 1800 lumens each.

For the sake of confusion would you mind forwarding me links to the T5 and T8s you're referring to? 

Please see below:

Do the T8s need a reflector-type hood to be more efficient because the light radiates out? Or do they already focus downward? 

The light is emitted at a 320-degree angle. A reflector is not necessary but may help in producing a bit more "useful" brightness.

Diffusion difference between T8 LED Tube, Shop Light, and T5 Linear Fixture

I am a fine art photographer who is evaluating large prints that will ultimately be shown in museums and galleries and private residences. I'm having a difficult time understanding the differences between the NorthLux™ 95 CRI T8 LED Tube for Art & Studio in 5000k and the D50 5000K T8 LED Tube Lights for Color Matching. Is the light output different between these two options? I am not needing any sort of specific ISO spec, just looking for the best quality of light for the application. Also, I am curious about the differences in diffusion between the bare tube, the T5 linear light fixture, and the shop light. Is there any noticeable difference in the quality of light- ie more even diffusion from the linear or shop light? 

For starters, we can confirm that the 5000K NorthLux™ 95 CRI T8 LED Tube for Art & Studio and the D50 5000K T8 LED Tube Lights for Color Matching are identical products that are provided with unique landing pages for marketing purposes. As such, the performance can be expected to be identical across both items, though we do apologize for any confusion this may have caused.

Also, we're not sure that we can provide any applicable metrics or specifications on this, but it would seem to me that the diffusion performance of the T8 LED lamps would be best, followed by the T5 linear fixtures, and finally the shop light fixtures.

The reason for this is that the T8 lamps, by definition, have a 1-inch diameter and this allows for the light to spread out from a larger surface area compared to the T5 lamps, which have only a 5/8 inch diameter. The shop lights do not have any diffusers on them, and all light is directed downwards from the fixture. As such, if glare and "hotspots" are of concern, we would not recommend the shop lights for your installation.

​Compared to the T5 fixtures, the downside of the T8 lamps would be that you would need a separate fixture, but if you are looking for the softest, most diffuse light source, the T8 lamps would be our recommendation.

Do you have a T8 LED Tube Light to fit the Phillips UltraLume F15T8/85U fixture?

The above sounds perfect however the length needs to fit a 17" (18"?) double-tubed Fluorescent Drafting Table fixture (the classic from 20 years ago - currently using Phillips UltraLume F15T8/85U 5000K bulbs). Do you have the NorthLux™ 95 CRI T8 LED Tube for Art & Studio bulbs in a size to fit these classic lamp fixtures? I think I may shift to 6500 or order sets of 4 of each D50 and D65 for viewing prints. And will the LED work in a Fluorescent fixture? 

At this time, we currently only have the 48” length of the T8 LED tube light products available in our catalog. We apologize!

That said, we can confirm that our LED tube light products function in fixtures that utilize a compatible ballast. In case it proves to be useful, we have provided a link to the compatible ballasts below. 

Additionally, these lights can also be installed utilizing a ballast bypass method, in the event that the pre-installed fixture ballast is incompatible. 

Compatible Ballasts List

LED Lighting for Painting and Palette

I'm always in search of "perfect" lighting for the longest time. I have been using a combination of many things. I have incandescent fluorescents with a CRI index of 95 (I think). I've been using them in combination with Solux bulbs. I wanted to ask you what lighting you have that would be good for my studio setup. I require a lot of light, from the ceiling, on my canvas, and my palette. 

If you would like to utilize the highest CRI for your artwork creation, we might recommend the ABSOLUTE SERIES™ LED Flexible Strip product, which features a CRI of 99, making it virtually indistinguishable from natural daylight. Additionally, it might be helpful to know that this product is available in both the D50 and D65 ISO standards, which many of our customers find useful for artwork creation.

The Absolute Series LED strip lights can be installed within wall-mounted channels and can be powered either through a DC power supply or paired with an in-wall dimmer and in-wall TRIAC dimmable power supply.

This is not for display. It is lighting for painting and palette.

If the installation is meant for artwork creation such as painting rather than simply display, we would likely still recommend the Absolute Series of LED strip lights. Additionally, it might be helpful to know that many of our customers have chosen to replace their fluorescent fixtures or track lighting with the Absolute Series LED due to the high CRI output, which can be beneficial for artwork creation.

Alternatively, you may also be interested in the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product for your fluorescent fixtures, though please be advised that the T8 lights are not compatible with all ballasts found within fluorescent fixtures.

As such, we would strongly recommend confirming compatibility using the ballast compatibility list, which I have attached below.

T8 LED Tube Light Ballast Compatibility List: https://www.waveformlighting.com/files/CD4020.txt

So, my setup is a bank of six 4-foot T12 incandescent fluorescents with a purported 94 CRI. I also have two Solex diffused bulbs and a Solex on my palette. I need a lot of light.

If you have a set light output in mind, we would recommend reviewing our Lumen Estimation Calculator tool, which we have provided a link to below. This tool is designed to recommend precise lumen output when the dimensions and purposes of the space are entered. I do hope that it proves to be useful for your installation planning!

Lumen Estimation Calculator: https://www.waveformlighting.com/lumen-calculator

High CRI LED Light for Paint Booth Lighting

I am looking to replace some lighting in a paint booth for spraying finishes on wood products. Looking for high CRI and possibly 5000k or 6500k for the ability to see colors well. What would recommend? These are 4' t12 fluorescent bulbs now but I'm willing to change or build any sort of panel needed to replace them.

Though our T8 LED tube light products are likely incompatible with the ballast and power output of the T12 fixtures, we are happy to confirm that our NorthLux™ 95 CRI T8 LED Tube for Art & Studio product is available in both 5000K and 6500K, and could to be a great option for your paint booth if you were to utilize T8 fixtures.

As such, you may be also interested to know that we have LED-Ready T8 tube light fixtures, which are designed to be compatible with our T8 LED tube lights without needing to consider potential ballast compatibility issues. 

Additionally, you may also be interested in the ABSOLUTE SERIES™ LED Flexible Strip product, which has a CRI of 99, making it virtually indistinguishable from daylight, and is available in both the D50 and D65 ISO standards.

The LED strip lights can be installed within wall-mounted channels and can be powered either through a DC power source or paired with a wall dimmer and in-wall TRIAC dimmable power supply.

I am actually interested in the absolute series and I was curious about the spread of light as far as putting out an even dispersion of light. If I put 4 strips 4' long evenly spaced in a fixture that had 4, 4' fluorescent tubes would be a similar spread of light and possibly brighter overall? Also, would I need one power supply per 16' of the absolute series strips?

To confirm whether the output would be sufficient, we would recommend comparing the lumen output of each of the preexisting T8 tube lights with the below information. As the Absolute Series LED Strip Lights have a lumen output of 375 lumens per foot, that would mean that each 4-foot section would output 1500 lumens. 

​If you were to compare the 1500 lumens with the existing T8 light output (which should be listed on the outside of the tube light), then we would then have a better idea of the comparative output. Additionally, we can confirm that we generally recommend utilizing one dedicated power supply per 16.4-foot reel of the LED Strip Light products.

Flicker Rate of T8 LED Tube Light

Do you have the "Flicker % or Flicker Index" spec, or some other flicker spec, for "CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light" 4000K .. similar to what's listed for your A19 flicker free bulbs? 

We are happy to confirm that the T8 LED tube lights in our catalog offer a <1% flicker rate, and a flicker index of 0.00 when connected to a fixture that utilizes a compatible ballast or utilizing a direct-wire connection.

Flicker-Free T8 LED Tube Light

I am trying to use these lights for my film studio, where I shoot high-speed video at around 1000 frames per second. Would this work for this type of application? Can I use a standard LED T8 light fixture for these bulbs and still get a "flicker-free effect?"What is meant by "Flicker-free" when connected without a fluorescent ballast?

We are happy to confirm that our flicker-free lights, such as the T8 LED tube lights, can refresh at a higher rate than would be noticeable in a 1000 fps capture.

Generally speaking, most older fluorescent tube light fixtures utilized a ballast within them to regulate the power being supplied to the lights. As this is no longer necessary for LED products such as ours that contain internal transformers, some older ballasts are incompatible and can cause performance issues such as flickering.

As such, before ordering, it may be worth ensuring that the ballast within your fixture is within the compatibility list. If they are not, it might be helpful to know that we are looking forward to releasing our own line of LED-Ready tube light fixtures within the next month or so. 

​Additionally, fixtures with ballasts can still be used without lights when a ballast-bypass installation type is used, which is illustrated within the below product installation guide.

 So if I were to use my own lighting fixture (a none waveform fixture) for the "Flicker-Free T8 LED Tube Light" I would need to make sure the ballast in the fixture is on the compatibility list.

That's correct! Though it may be helpful to know that the fixtures linked are integrated and do not require any lights to be installed. These are different from the upcoming line of LED-Ready T8 tube light fixtures, which can utilize our T8 LED tube lights.

Can you recommend any lighting fixture you know has the proper ballast for the "Flicker-Free T8 LED Tube Light?"

Unfortunately, we do not have any specific fixture models that we could recommend at this time. We apologize! 

If I wanted to get the Flicker-Free A19 10W LED Bulb, could I use a standard e26 or e27 socket and still remain flicker-free?

We are happy to confirm that the internal hardware of the A19 bulbs will allow for flicker-free functionality when installed within a matching E26 or E27 base. We have also attached a blog post below which describes the hardware and voltage differences between the two sockets, which may prove to be useful.

E26 vs E27 Bulbs - Interchangeable? Not Necessarily!: https://www.waveformlighting.com/home-residential/e26-vs-e27-bulbs-are-they-interchangeable

Do the " Flicker-Free T8 LED Tube Lights" have single-ended or double-ended power? Can they operate in a single and double lamp fixture configuration?

We are happy to confirm that our T8 LED tube lights can be installed and powered using either single or double-ended power configuration.

As such, please feel free to utilize them within compatible fixtures that utilize either of the above "UL Type B" installation types. The available configurations for that type can be found in the installation guide, which I have provided a link to below.

Flicker-Free T8 LED Tube Installation Guide

What is the difference between the NorthLux™ 95 CRI T5 LED Linear Light Fixture and the D50 5000K T5 LED Linear Light Fixture for Color Matching?

We can confirm that the two products are identical, though they are provided with unique landing pages for marketing purposes. This can be noted by the shared part number, though I do apologize for any confusion this may have caused.

Are both of these lights flicker-free? What is the PWM frequency of these LEDs?

Yes! Both products offer a <1% flicker rate and a 20kHz frequency.

If they are flicker-free, can I use third-party daisy chain cords, accessories, extension cords, etc., and still get a flicker-free effect?

Yes, the flicker-free functionality should be preserved when utilizing a compatible third-party C8 plug cable.

How many units can be daisy-chained into a single outlet?

A total of 70 feet (21 meters) of the linear light fixtures can be safely daisy-chained together.

What do you mean by a <1% flicker rate? At 20kHz frequency, would that mean I can shoot video at a maximum of 40,000 frames per second before seeing the flicker?  

We typically say that our products have a flicker percentage of less than one percent in marketing materials, though the actual flicker rate of our flicker-free products is 0%, with a 0.00 flicker index when tested.

We have attached a link to the spectrum test report for one of our flicker-free A19 bulbs below, for your reference. Upon review of the last page, you will see an example of our test data showing a 0% flicker rate. You will also see that the flicker index is 0.00, as there is an extremely minute variability between the maximum and minimum light output per hertz cycle. As such, we would not expect any visible flicker at that capture rate. 

​

LED Tube Light for Slow Motion Video

We are moving into a 30k+ sq ft facility here over the next few months and are looking to outfit the space with "flicker-free" LED tube lights. We are a baseball development company that utilizes high-speed video regularly and in a perfect world. We would be able to shoot 1000 fps anywhere in the facility, given that the lighting was outfitted correctly. Would love to hear your thoughts on the matter. 

We are happy to confirm that our flicker-free T8 LED tube light products operate with a refresh rate that is much higher than the referenced 1000 frames per second capture rate for filming. As such, they could be a great match for your installation purposes.

That being said, it would be worth confirming whether our T8 LED tube light products are compatible with the preferred lighting fixture ballasts to be installed in the new space to ensure optimal functionality prior to ordering.

If the ballast within the fixtures is not on the compatibility list, we would then recommend either identifying an alternative compatible fixture or looking into the available ballast-bypass installation methods listed in the product installation guide.

​In the interim, you may be interested in our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are available in both 5000K and 6500K, which are commonly recommended for industrial settings.

Our main concern is outfitting our space with true "flicker-free" lighting systems to ensure 1000 FPS comes out in the highest quality possible for content purposes.

If you can make some recommendations accordingly in regards to outfitting our whole space with this type of light would be greatly appreciated and a general quote for the bulbs as well. In addition what would be the most compatible fixture to ensure proper performance of the lighting system.

Upon review, our primary recommendation will be to ensure that the fixtures contain compatible ballasts.

If the ballasts are incompatible, then they may experience flickering, sub-optimal operation, or failure to operate. As such, we strongly recommend comparing the ballasts within those ballasts with the compatibility guide. 

It appears that you are currently utilizing a series of 6500K color temperature tube lights. As such, we would suggest our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product.

We also recommend comparing the lumen output of the preexisting fluorescent tubes to ours in order to ensure that the current quantity of light fixtures emitting light at that output level would be sufficient for any industrial or capture purposes. If our T8 lights emit fewer lumens than the existing fixtures, we would then suggest installing additional fixtures.

Finally, we also recommend getting in touch with a local lighting designer in order to ensure that the entire building and work areas are sufficiently and evenly illuminated by the T8 lights.

Do you have a Light that is compatible with Columbia LCAT 22?

Do you have a Light that is compatible with Columbia LCAT 22, which is healthy to be under all day, and give "outdoor" lighting?

Based upon a quick search, it appears that the Columbia LCAT 22 has integrated LEDs that cannot be removed or replaced. As such, you will likely need to replace the entire fixture in order to modify the light properties of the existing setup.

The closest option we would recommend would be our T8 LED lamps (link below) which require a traditional fluorescent fixture. 

Centric Daylight vs NorthLux for Home Office

For a 5000k bulb, is there any difference between the Centric Daylight and Northlux brands? There are different write-ups, but most of the specs seem the same. Northlux doesn't mention flicker free but I assume it is? Also, do you have any sort of discount for purchasing an 8-pack of either? And lastly, and plans to support dimming? 

The CENTRIC DAYLIGHT and NorthLux lamps differ slightly in their chromaticity specifications. Generally, the NorthLux lamps will provide a higher level of chromaticity precision and may be beneficial for any color-critical tasks. Both are fully flicker-free. 

​Please see below for additional information:

https://www.waveformlighting.com/knowledgebase/what-is-the-difference-between-centric-daylight-5000k-6500k-and-d50-northlux?src=pse

​We unfortunately do not have any discounts or pricing configurations apart from our 1-pack and 6-pack quantities and apologize for any inconvenience.

I'm wanting to order some of these T8 bulbs for my home office. It's primarily a computer-based office. I might occasionally do some painting here in the future. My main concern is eye strain. Is there a color temperature/variant you'd recommend for a home office for computer work?

​It sounds like our 4000K or 5000K version of the CENTRIC DAYLIGHT T8 lamps would be a nice fit for your needs. The 4000K will provide a warmer, softer daylight color (similar to morning sunshine) which will provide a bright lighting environment without being overly blue or stark, especially during evening hours.

5000K may be preferred if you are looking for a color that is better natural daylight color. If your home office gets lots of natural daylight, for example, the 5000K may be a better match, especially for painting and other artwork. Unless you have north-facing windows and need a perfect match to north-facing natural daylight, we would not recommend 6500K.

As far as eye strain is concerned, all of these color temperatures offer flicker-free light output and are spectrally calibrated with a 95 CRI rating, so in theory, none of them should cause any issues unless you find natural daylight itself to also cause eye strain issues. Historically, fluorescent lamps have induced lots of flicker with a poorly calibrated daylight spectrum, so I totally understand the concerns, however, and 4000K may be the most comfortable light color, especially for evening use.

Are there better T8 light fixtures that you'd recommend to be used with your CENTRIC DAYLIGHT T8 LED bulbs?

Based on the review, it appears that the Grainger and Sustainable Supply products are not compatible, as these fixtures are designed for 96” lights, whereas our T8 products are 48".

That said, it does appear that EnviroLite would be compatible - although we do not see technical data provided for the ballast within the fixture. It may be worth reviewing to be sure that the ballast within is compatible with our T8 lights. 

If it is not, we can confirm that most T8 fixtures are compatible with our lights when installed via the ballast-bypass method.

High CRI 90 3000 lumens and 4000K Panels for Downlighting

Looking for roughly 3000 lumens per light with 4000K and High CRI panels or something that will work in a drop ceiling. 

We can confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights offer 1800 lumens per unit. Based on the details provided, we would recommend the 4000K version of this high-CRI product as the closest match within our product catalog.

Does the NorthLux 95 CRI LED Shop Light Fixture come in 6' lengths?

I am currently building a home with an art studio above the garage. I am interested in the NorthLux™ 95 CRI LED Shop Light Fixture. Do they come in 6' lengths? Can they be hardwired so that you don't have to pull the chain each time? I am also trying to decide between 5000 and 6500 leaning towards 5000. I am a Fine Art Photographer and an abstract acrylic painter. 

Unfortunately, the LED shop light fixtures are not available in other sizes at this time. Further, these products are not designed to be hard-wired, though I can confirm that multiple units can be daisy-chained together to utilize a single power source.

As an alternative, it might be helpful to know that we are soon to release a T8 LED tube light fixture, which is designed for hard wiring and ceiling mounting. This fixture would be compatible with our high-CRI T8 LED tube lights, which are also available in 5000K and 6500K. Though I currently do not have a specific launch date, I expect that it will be available in May.

Regarding the preferred color temperature, I have attached a link from our blog below, which describes the benefits of each for studio work.

Difference Between 5000K and 6500K Bulbs: https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Can you suggest a LED lamp works with an overhead cubicle florescent 48" BiPIN fixture?

We do not have LED lighting installed, rather 48 in BiPIN florescent tube light overhead. I want to replace it with full spectrum type lighting because the 'normal' lamps custodial installed are not very acceptable since I'm used to working from home office streaming in natural lighting. The custodian explains the district doesn't provide a 'special' lamp however I'll need to buy it but OK for installation. Is there a smaller package of lamps you'd suggest and will these lamps work in fixtures we have?

Based on the details provided, we might first recommend checking to ensure that the lighting fixtures in your office are compatible with our T8 LED tube lights. 

​Further, for office lighting, we recommend the 4000K color temperature of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are available in 4-Packs and offer full-spectrum light output with a CRI of 95.

Occasionally, older fluorescent fixtures utilize electronic ballasts which are incompatible with LED products. Though we do offer illustrated guides for ballast-bypass methods for such fixtures, this process may not be feasible for all office spaces.

That being said, we have attached a link to the list of compatible ballasts below, as well as the instructions for ballast bypass wiring installation.

If you would like to purchase a 4-Pack of our T8 LED tube light products to check for compatibility with the fixtures in your office, please know that we are happy to offer a 30-day return policy for all orders.

Do you recommend LED Strips or Tubes for an Office Space?

I will be working in a very small 8’ x 10’ office space, an enclosed room with no windows. This is not an art studio, just office space but lighting is so important to me.

Do you recommend LED strips or tubes? I suspect they may prefer to use tubes, but willing to advocate for strips if you strongly recommend that. If we go with tubes which fixtures do you recommend? Looks like your LED tubes are compatible with any T8-type fixture, but I am not familiar with ballasts and so forth. Better to get without the ballast? What k rating would you recommend?

As our T8 LED tube lights use the same LED light emitters as the LED strip lights, the selection between the two generally comes down to preference. While the LED strip lights can be installed in many more configurations (such as within channels or fixtures), they do require accessories and power supplies.

Alternatively, the T8 LED tube lights are easy to replace and configure while offering the same quality of light and high CRI. The downside to the T8 LED tube lights is that they, unlike the strips, are not compatible with dimmers.

Though we do not have any specific T8 fixtures to recommend at this time, a key term that might be helpful in your search is ‘LED ready’, as these products do not contain ballasts. Based on my review, it appears that Home Depot has many LED Ready fixtures available. That said, the ballast bypass installation method referenced in the below guide allows for any T8 fixture to be usable with our tube lights.

For office lighting, we generally recommend 4000K as it offers a neutral, balanced white color that isn’t too cool or warm.

T8 LED Tube Light Installation Guide: https://www.waveformlighting.com/datasheets/UM_4020.pdf 

If two light LED-ready tube fixture is installed is it possible to have only one light in the fixture? Or must there be two lights in the fixture to make it work? The bottom line here is if two tubes would be overpowering could I take one out and possibly augment with some of your lamp bulbs more at desk level?

The answer would depend on the electrical layout of the fixture, though we generally assume that LED Ready T8 fixtures are designed such that a single light should work without needing a second to be installed.

T8 LED Tubes for Seed Starting & Ballast Compatibility

Is the PhotonTube part number 4024.65.4P compatible with a Phillips Advance REB-2P32-N ballast? I found a ballast compatibility document that lists that ballast as being compatible with your part number 4020 LED tubes. Is that document now obsolete? What is the recommended T8 LED tube height range above plant seedlings? I'm considering a 4 FT 4-lamp T8 LED fixture for my plant shelves. Currently, I'm using a 2-lamp 32-watt T8 fluorescent fixture, and its underperforming.

We're happy to confirm that as our current T8 LED tube light products are of the same family line, the ballast compatibility listed within the document referenced is still current and able to be referenced. 

​As our T8 LED tube lights will emit a far lower amount of heat than traditional horticulture lamps, heat damage to the seedlings is less of a concern. As such, we recommend placing the lamps as close to the seedlings as possible without touching them. That said, different plants might require more precise distances from the light to receive the maximum benefit.

Is Centric Daylight T8 LED Tube compatible with Keystone Ballast fixture?

I am building a new house with a 3-car garage for detailing, so need high CRI. I have 11 linear ceiling fixtures, each for 2 T8 bulbs. Are your centric daylight 5000K compatible? Can you tell if they will be flicker-free in this fixture? They are currently using Keystone ballast, model KTEB-232RIS-1-TP-SL. The specific model is not on the tested ballast list.

Based on my review, I can confirm that the ballast provided has not previously been tested with our T8 LED products.

That being said, it does appear that the KEYSTONE KTEB-332-UV-IS-N-P ballast has been tested as compatible. If the items are of the same manufacturer product family, I do believe that they might work well!

Alternatively, as previously mentioned, the T8 LED lights can always be installed using a ballast-bypass method if the ballast is incompatible.

Does your T5HO Grow Light Tube Compatible with SunBlaster T5HO Fixtures?

I have 4' Sunblaster T5HO self-ballasted fixtures. Are your tubes compatible with these? They were not on the list of compatible brands, but the FAQ for tubes indicates they are compatible in ANY T8HO fixture, which is not T5HOs. 

Do your tubes retain CRI value throughout their life? Is that the 3 years you posted for other tubes? 

Based on the details provided, it does appear that the PhotonTube™ T5HO LED Grow Light Tube for Horticulture would be compatible with the SunBlaster fixture that was mentioned. However, if you find the products to be incompatible for any reason, please let us know and we would be happy to assist with returning your order.

Though the T5H0 fixture will exhibit a slightly reduced output throughout the lifetime, the CRI will not reduce during the lifetime use of the product. 

Light Fixture for PhotonTube T8 LED Grow Lights

I am inquiring about where/what type of light/lamp I can purchase that would hold your 48” Photon tube LED ”grow” tubes. I am also hoping you can clarify the statement about being able to interchange them with fluorescent tubes, either with or without removing the ballast. 

The key term to look for when selecting compatible T5 or T8 fixtures that do not require ballast adjustment is ‘LED Ready’. LED Ready fixtures are typically designed without ballasts and allow for the T5 or T8 products to be immediately functional. Based on my review, there appear to be several T5 and T8 fixtures available from online marketplaces.

As older fluorescent light fixtures often utilize ballasts, there can be instances where the LED retrofit lights (such as ours) are incompatible with the ballast hardware. In these instances, we recommend a ballast-bypass, which allows for the lights to be directly powered by the wiring in your space.

I have attached a link below for the product specification sheet, which illustrates the ballast-bypass configuration.

Product specification sheet: https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

My understanding is your photontubes replicate the sunlight spectrum and are good to use on seedlings, is this correct? Are there fixtures you can recommend that work with these (not sure you are allowed to do that), or alternatively is there anything that I should be on the lookout for with regards to purchasing?

One other question, what is the area (sq. footage?) that 2 lights (2 bulbs) would illuminate if at about a 4 inch distance from its subject? 

We can confirm that our 6500K PhotonTube™ T8 LED products are designed to output light that closely simulates daylight to benefit seedling growth.

Though we do not have any fixtures to recommend at this time, we would be more than happy to check any fixtures that you are considering for compatibility. Regarding the square foot light output, I would be more than happy to confirm the technical details with my team. As soon as I have received confirmation, I will plan to let you know right away.

It might also be helpful to know that we offer a 30-day return policy for all orders. In the event that these products don’t work well for your installation, just reach out and we will gladly issue a prepaid return label.

Difference between Centric and NorthLux Products

Would you be able to let me know if there is any difference between the Centric bulbs and NorthLux bulbs with the same color temperature? I noticed that there are a number of products where there are Centrix and NorthLux bulbs with the same CCT, wattage, and price, and online pictures. I'm curious as to whether the products differ in some way. 

We can confirm that some products, such as the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) are actually identical items that are given unique landing pages for marketing purposes. 

​By comparison, though the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED product is of the same family line, the 5000K color temperature does not conform to the D50 color standard as the above products do.

We do apologize for any confusion this might cause in your order planning. As a general note, identical products can be noted by the shared part number. For the above D50 products, that number is PN4005.D50. In these instances, the functionality and performance will be identical, though the color temperatures available might change.

Are there fixtures available without ballast built-in?

Are fixtures available without ballast built-in or should I just purchase a fixture w/ ballast and bypass?

Based on our review of marketplaces such as Home Depot and Amazon, there appear to be several models available which are labeled “LED Ready”. Generally speaking, “LED Ready” T8 fixtures will not include the ballast, and should not require any wiring adjustment or ballast bypass.

What is the difference between the Centric Daylight 5000K and Northlux 5000k bulbs?

What is the difference between the Centric Daylight 5000K and Northlux 5000k bulbs? What is the R9 rating for the Centric Daylight 5000k bulb? Also, do the 5000k bulbs give off a blue hue to them? 

The difference between the CENTRIC DAYLIGHT and NorthLux bulbs is that the NorthLux bulbs are calibrated to the D50 and D65 color standards which may be crucial for certain visual tasks. Both feature 95+ CRI and R9 values of 80+.

The 5000K lamps could certainly be perceived as being blue, especially during evening hours, and compared to incandescent and other warm white LED lamps. 

Here is an article going over some aspects of 6500K lamps, many of which would also apply to 5000K lamps:

LED Tube Light for Photo Print Studio

I need an LED tube bulb that is guaranteed not to go below 400nm (a photo print studio); any thoughts?

We are happy to confirm that our T8 LED Tube Light products, such as the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product, will not emit UV wavelengths. As can be noted in the product spectrum test report below, the spectral distribution trails off before the 400nm wavelength.

T8 and T5HO Daisy-Chaining Set-up for Wire Shelving

I'm looking to direct wire either T8 or T5HO tubes(4ft), but am having trouble figuring out the best way to set them up for wire shelving racks. Ideally, I'd love to have them daisy-chained between each shelf, similar to these orchid lights. I'd prefer Waveform Lighting for the high CRI, so I'm looking into T8/T5HO sockets that can be plugged onto both ends and then into either a power source or daisy chained to the next light. Do you have any suggestions, or can you tell me whether this is possible with your 100W power supply? 

Though we generally do not utilize our T8 LED tube light products within a daisy-chain installation, we believe that these products would be compatible with the connector that was referenced so long as the 'UL Type B' installation method illustrated within the T8 product sheet is utilized. 

​Regarding powering these products, we would recommend utilizing 120-277V AC. As such, the 100W power supply would be incompatible.

Flicker-free T8 LED Tubes for Vision Therapy Office Lighting

We are a vision therapy institute that sees patients recovering from traumatic brain injury. One of the symptoms of post-traumatic vision syndrome is an extreme sensitivity to light. Our office has regular fluorescent ballasts. We're looking for a solution with a lower flicker rate and a warmer color temperature. Will purchasing your T8 tubes solve for our flicker rate issues or will we see flicker at the same rate as the current fluorescents? 

Based on the details provided, we might recommend our 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product for your office installation. 

​While we can confirm that this product offers flicker-free performance, it might be helpful to know that some tube light fixtures contain pre-installed ballasts which are incompatible. When these products are installed within fixtures that may have not been designed for LED products, they are more likely to exhibit compatibility issues.

However, we do offer an illustrated guide to the alternative ballast-bypass installation methods, as well as a guide for the ballasts which have been tested for compatibility. For your reference, we have included both links below.

Tested Ballast List: https://www.waveformlighting.com/files/CD4020.txt

F40T12 48" Fluorescent Replacement for Bathroom Lighting

I need to get a replacement for the F40T12 48" natural light fluorescent in the bathroom. My wife liked the LED lights I purchased from you in the past. 

While we only sell T8 LED tube light products, we're happy to confirm that our T8 lamps can be used in your existing T12 fixture with the T12 fluorescent ballast removed or bypassed.

You may refer to the installation guide below. 

ballast-bypass installation method described within the product guide.

Do you offer the T8 LED Tube Lights in a 59-inch (150 cm)?

I am very interested in this product for my Print Studio (D50 5000K T8 LED Tube Lights for Color Matching) but my sockets are 59 inches (150cm) wide. Do you offer this product in this size or only in 48 inches (120cm)? I'm also interested in this Product (NorthLux™ 95 CRI LED Shop Light Fixture) Did this has a clear cover in front of the LED or has it a matte cover so that it does not dazzle strongly and is somewhat softer?

Unfortunately, our T8 LED tube lights are only available in the 48-inch length at this time. For now, we don't have immediate plans to offer additional product sizes. We apologize for any impact this might have on your planning purposes.

However, we're happy to confirm that the newest batch of the NorthLux™ 95 CRI LED Shop Light Fixtures will ship with an installed frosted diffuser cover. 

Recommended High CRI LED Lights for Art Gallery Lighting

I am a member of an artist-run art gallery. We have a new gallery space and would like to know what kind of lighting you recommend which would give us full spectrum color. We will want spots and perhaps tube lighting, all dimmable if possible. An architect friend recommended we get high CRI lights, at least in the 90s.

Based on the details provided, we might recommend our dimmable Full Spectrum E26 BR30 LED Bulbs. These BR30 products can provide a great full-spectrum high-CRI solution for track lighting systems.​

Regarding our tube light options, you might be interested in our NorthLux™ 95 CRI T8 LED Tube for Art & Studio product. Though these T8 LED tube lights are unfortunately not dimmable, they do offer a CRI of 95+ while being compatible with many fluorescent T8 fixtures.

LED Horticultural Lights

I'm interested in purchasing 200 units of your "PhotonTube™ T8 LED Grow Light Tube for Horticulture" LEDs. It is for a Caribbean-based trial strawberry plant factory (1/20 the final order size) and from the photos I can see that these lights have been tested with this crop. What discounts are available for orders at this volume? What can you tell me about its performance with strawberries? What technical support can you offer in selecting the correct drivers and connections for my system?

We can confirm that we are able to offer volume discounts, which are determined by quantity per order, per product. As such, an order containing 200 units of the PhotonTube™ T8 LED Grow Light Tube for Horticulture product would qualify for a 6% discount.

Unfortunately, we are unable to provide any data on how the use of these lights might impact strawberry farming, as we generally do not perform diverse horticulture product testing in-house. However, we can confirm that the high CRI output of these products will closely resemble that of natural daylight.

Regarding technical support and compatible drivers and fixtures, we would be more than happy to review any provided fixtures in order to check for compatibility. Generally speaking, T8 tube light fixtures that do not contain a ballast, or are advertised as ‘LED Ready’, will be the most compatible with these products.

Difference between NorthLux and D50 T8 LED Tube Lights

I am wondering if you could help me with a few questions about specific products of yours: 

NorthLux™ 95 CRI T8 LED Tube for Art & Studio & D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) What is the main difference between these two lights? I'd get them in 6500k. Are they both near daylight quality? They are for my workshop. I'd like it as close to daylight as possible. 

Regarding the 2 above lights, what is the footprint size of the light the fixtures emit? How many square feet of light would each tube emit? 

I see that you offer the same quality lights but in a T5 fixture. What is the square footage of light emitted for the T5 fixtures with CRI95? 

We can confirm that the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product and the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) are identical products which are provided unique landing pages for marketing purposes. This can be noted by the shared part number of both products. We would like to sincerely apologize for any confusion that this might have caused.

As the footprint size of the light output generally scales depending on the area that the light is filling, it would be difficult to know what the footcandle measurement would be without knowing the dimensions of the space. As such, our lumen estimation calculator tool might prove to be helpful for your planning purposes. By inputting the dimensions and selecting the planned purpose of the space, our web tool will assist in suggesting the right quantity of lighting products to meet your ideal output.

In the interim, we can confirm that each of the products has an 1800-lumen output. Further, the 6500K color temperature option is designed to emit light that is extremely similar to north-facing daylight. Alternatively, our 2ft NorthLux™ 95 CRI T5 LED Linear Light Fixtures have a lumen output of 900, whereas the 4 ft fixtures will have an output of 1800 lumens.

Compatible Lighting Fixture with T8 LED bulbs for Growing Plants

I want to know what kind of portable fixtures I can use for T8 bulbs for growing plants. I do not want to direct wire them.

We're happy to confirm that our T8 LED tube lights are compatible with many fixtures which do not utilize direct wire installation. However, it might be helpful to know that some fixtures utilize ballasts that may not be compatible with LED lighting.

To select a compatible lighting fixture, we might recommend searching for the term ‘LED Ready’, as that generally denotes compatibility with retrofit T8 style LED lights. Based on my review of third-party storefronts, it appears that there are several available through markets such as Amazon and Home Depot. However, we, unfortunately, do not have any specific models that we can recommend at this time.

The specification sheets for our T8 LED tube lights also include instructions for alternative installation methods, which might prove to be helpful: 

https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

For a list of the ballasts that are compatible with our T8 LED tube lights, please reference this link: 

https://www.waveformlighting.com/files/CD4020.txt

What should the Lux be for the 6000K T8 Grow Light?

What should the Lux be for the 6k T8 grow light? I'm curious if the light fixture I bought for the bulbs is sufficient. And if it's not sufficient what fixture do you recommend?

We can confirm that the PhotonTube™ T5HO LED Grow Light Tube for Horticulture product has an output of 1800 lumens per unit.

Household Bulbs for House Plants

I'm trying to find a regular household-type bulb that would be great for daily use and house plants. I'd like to use adjustable arm table lamps, or pendants to light single plants or a small display and match temp to all other bulbs in the home. I'll change all if necessary. 

Based on the details provided, there are a few different products that we might recommend depending on the preferred color temperature output.

For starters, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb product. Though these are not dimmable, they offer flicker-free performance and a high CRI. Further, the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products could look quite nice on a shelf display among plants.

We have attached a blog post link below from our website regarding color temperature selection, which might be helpful for your planning purposes.

Which LED Light Color Temperature Should I Choose?: https://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose

As our A19 bulbs will offer a very similar quality of light output, the right option might be better defined by the purpose of the space. For example, while we might recommend a 4000K option for a home office space, we would alternatively suggest a 3200K for a reading area.

I read the blog but didn't see anything about plants. Maybe I should rephrase my question. Which of your A19 bulbs has the correct spectrum and other properties to grow healthy houseplants? These plants are typical tropical varieties composed of mostly foliage, not flowering. Most prefer bright to medium indirect light. Some small 6" ish pots on a tabletop and some large floor plants. I just want to use a variety of attractive lamps that accept regular bulbs.

Though our High CRI A19 bulbs have not been specifically designed for horticulture as some of our other products have been (such as the PhotonTube™ T5HO LED Grow Light Tube for Horticulture product), I am happy to confirm that they offer an extremely similar full spectrum light output to those of our horticulture-focused products.

Regarding the right color temperature for your installation, you might find benefit in either the 4000K or 6500K options of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

While the 4000K provides an output that simulates late-season light, the 6500K option will offer light that is very similar to natural daylight and simulates the light which occurs in early-season growth periods. For an in-depth analysis of the technical benefits that our full spectrum lighting has on plant growth, we have attached a terrific blog post from our website below.

Full Spectrum LED Lighting for Big Aviary and Horticulture

I would like to confirm that your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light can be used for lighting in my indoor aviary (dimensions: 80" H, 86" L, and 62" D). I cannot use the Full Spectrum BR30 LED Bulbs 4000K / 5000K / 6500K as I would need several of them and my ceiling is glass (the aviary is inside the sunroom). If my assumption is correct, can the tubes be plugged in or are they only hard-wired? I can only plug them in based on my setup. If there is no plug-in version of the tubes, are there alternative LED strips I can use that are full-spectrum? Finally, are the horticulture tubes hardwired or can they be plugged?

We can confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights are compatible with 4 ft fluorescent tube light fixtures which utilize the G13 base.

However, it might be helpful to know that these lights are not compatible with all ballasts present within fluorescent fixtures. Generally speaking, product incompatibility with ballast models may cause flickering, or a lack of functionality. For a full list of ballasts that have been tested as compatible, please review this link: https://www.waveformlighting.com/files/CD4020.txt

For further instructions regarding the installation methods available for these lights, we have provided a link to the product specification sheet below.

Product specification sheet: https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

If you would like to let us know which light fixture models you intend to use for the indoor aviary, we would also be more than happy to check to see if they are compatible with these lights.

Circadian Rhythm LEDs for Pharmacy Lighting

I'm looking to get lighting into my pharmacy in the most circadian rhythm-conscious manner. 

Based on the details provided, there are a few different products that we might recommend - such as the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product.

If you would like to let us know more about the light fixtures that you intend to utilize in the pharmacy, as well as the dimensions of the space, we would be more than happy to provide further product recommendations.

If it proves to be helpful for your planning purposes, we have a terrific post on our website regarding the selection of lighting color temperature options.

Which LED Light Color Temperature Should I Choose?: https://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose

Vapor Proof Casing for Filming Activities

I'm looking to outfit the work areas of our ship (the EV NAUTILUS) to better accommodate filming activities that occur over the year. I was considering the Centric Daylight bulbs (~48) but can you recommend a ballast-free vapor-proof housing to accompany it? At least IP65 is a deal. 

Our CENTRIC DAYLIGHT T8 LED lamps sound like a great fit for filming purposes!

​While we completely understand the need for a vapor-proof fixture that is pre-configured without a fluorescent ballast, unfortunately, we are unaware of any specific manufacturers or suppliers who may have such a product.

We do know that many of our customers who are looking for standard indoor lighting fixtures can find compatible fixtures by searching for "LED ready" fixtures - the "LED ready" marketing term typically suggests that the fixtures are pre-wired without a ballast inside.

We're not sure about the commercial availability of "LED-ready vapor proof fixtures," however, that would be my suggestion for where to start.

Alternatively, if you do have any existing fluorescent vapor-proof fixtures, from an electrical standpoint there should not be any issues removing or bypassing the ballast to ensure they are compatible with our lamps.

T8 LED Tube Light for Art Studio

I'm trying to find the best way to light a small studio. I came across your website and I think I'm interested in the Northlux 95 CRI T8. I'm having trouble locating a shop-style plugin/pull cord light fixture where I could use these bulbs. Do you have any recommendations on a specific light fixture or would you point me in a different direction using alternate bulbs for my situation? I currently don't have any hard-wired 4ft fixtures in my studio.

It is indeed a bit difficult to locate compatible fixtures as those available today are still configured for fluorescent lamps, which will almost always include a fluorescent ballast which may or may not cause compatibility issues.

​One tip we've had other customers have success with is searching online for "LED ready" T8 fixtures, which are configured without ballast and can accommodate our LED tube lights directly.

Artist Space Lighting

I'm an artist and want help in picking the right lighting for my studio. I think NorthLux™ 95 CRI LED Shop Light 5000K is the best choice, but I'd like to double-check. I see that it's back-ordered, when could I receive it? 

Our NorthLux line of products is indeed a great option for studio lighting!

Please tell me about other lighting that's good for an artist studio. The room is 10x12' with no natural light. Ceiling is about 8' high. I need great light over my table ,but if I can light the whole room that's even better.

Our options here would depend on the lighting fixture you would like to use.

​For example, we have some T8 LED tube lights which would require a 4-ft fixture to house the lamps. Alternatively, our A19 lamps will fit in standard screw-in lamp fixtures (E26).

​I have included the relevant product links below. If you can let me know a bit more about what you have in mind in terms of fixtures, please let us know and I'd be glad to assist.

T8 LED Tubes Lighting for Dental Office Operatories

I am interested in new lighting for my dental office operatories. My lighting needs have a very high level of color matching. Existing fixtures are approximately 20+-year-old fluorescent recessed troffers. I use T12 CRI 90 5000k bulb. Each fixture uses four 48" bulbs. I would like to improve my color-match lighting. What do you recommend? Do you have LED bulbs that will work in my existing fixtures? Do you recommend LED over fluorescent bulbs? 

Based on the details provided, we might recommend our D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product, as it is designed to be compatible with the D50 global standard for color-critical applications.

Regarding fixtures, we can confirm that these items are not compatible with all ballasts which are pre-installed within fluorescent T8 fixtures. However, we have compiled a list of tested ballasts, and include instructions on how to install these tube lights via ballast bypass methods on the product sheet.

As most fluorescent tube lights have a CRI of 80, the light output will likely wash out some colors. However, as our LED tube lights have a CRI of 95+, your office will benefit from much improved light output.

Does Centric Daylight T8 LED Tube Compatible with PLT Solutions Fixture?

I'm interested in buying these tubes because I can get them in 4000K. I need to buy fixtures though. I want them to be corded with a pull chain. I found these online - PLT Solutions (PLT-11668). Can you tell me if this fixture will be compatible? 

Based on our review of the product link provided, we are happy to confirm that the fixture appears to be compatible with our CENTRIC DAYLIGHT™ Full Spectrum T8 LED Tube Lights.

Full Spectrum LED Lighting for Grocery Store Installation

I'm an architect looking for lighting that mimics daylight as closely as possible for a grocery store installation.

PhotonTube T8 LED Tubes Replacement

I'd like to replace some standard T8 fluorescent lights with your PhotonTube T8 bulbs (4-pack). I'm pretty sure my lamps have an electronic ballast.

Our PhotonTube T8 LED tube lamps can be used in existing fixtures, as long as they have their ballasts removed, or their ballast is listed on the compatible ballast list shown on the user manual page below:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

​Since you mention that your fixture already contains an electronic ballast, you will want to check for compatibility before installing our lamps.

Recommendation for Starting Seeds Indoors

My wife starts vegetable seeds indoors in a north-facing kitchen garden window before planting outdoors. We are now looking to upgrade to LED grow lights. The lights can hang about 16" maximum above the seedlings. Would 1 PhotonBlast fixture be sufficient per shelf and also would 4000k or 6500k be best for starting seeds?

In my experience, the PhotonBlast should be a great fit for your needs!​In my setup, I had two PhotonBlast fixtures for a 48" x 18" wire shelf. Since your shelf is smaller at 50" x 10", you may be able to get away with just one fixture, but two fixtures would provide you with a bit more high-intensity light which can be helpful to prevent "leggy" seedlings, especially if you are growing high-density microgreens or similar crops.​The PhotonBlast fixture is approximately 48 inches long so this should provide sufficient coverage across the 50-inch shelf. Additionally, the 6500K should be a good option for seedlings, as this approximates noon daylight and should help promote vigorous leafy growth.

Centric Daylight vs Northlux

Which 95 CRI T8 LED Tube light is better? We are filming videos. Our other studio lights are 5500K but I am thinking the 5000K can work. They would be replacing the current ceiling lights which are quite warm. I was interested in the flicker-free Centric but the Northlux is advertised as studio lighting. Are there potential flicker issues with the Northlux? 

Our NorthLux T8 LED tube lights should work quite well for your needs! They are also flicker-free but not listed as such, since flicker is generally not a concern for most of our visual arts studio customers.

​On the other hand, we completely understand the concerns you have concerning flicker and on-camera use. As such, as an additional layer of assurance of flicker-free performance, we would recommend installing these lamps in a ballast-bypass configuration so that any flicker or other interference from electronic ballasts is not introduced into the light output stream.

We also do find that many TV/cinematography lighting systems are calibrated to 5500K / 5600K, however, the NorthLux 5000K should be a similar match, and the 95 CRI color accuracy should be a great fit for the film.

Ballast compatibility for PhotonTube T8 LED Grow Light Tube for Horticulture

The list identified in the pdf document is rather limited, so I am wondering if it will work with others. Specifically, whether it will work with these two ballasts: E2324IX-120 ballast and GE432-120RES-DIY ballast? I have some fixtures with each of these currently. I understand they will work in ballast bypass but I am interested in knowing if they will work plug and play without re-wiring the ballasts. 

Based on my review of our supported ballast list, it appears that the GE432-120RES ballast is likely compatible with our products. Though the product ID stem ‘-DIY’ is not listed, this may not be enough of a product difference for the ballast to be incompatible.

Unfortunately, the E2324IX-120 ballast does not appear to be listed among the compatible units. However, there is a chance that it is functional, but not internally tested as officially compatible.

Proper LED Products for Art Studio Lighting

I am an artist and have been on a long quest for proper lighting for my easel that will not distort colors. I have an east-facing window. I have read through much of your fantastic website, which is well done and very informative. I have a few questions:

Noting that I have an east-facing (not north) light source and think I would like the dimmable NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio Edison bulbs would you recommend the 5000k or the 6500K?

​Both color temperatures should work well for your needs; however, 6500K is generally a better fit for north-facing windows. As such, you may prefer the 5000K for your east-facing window setup. 

​Please see below for additional insights from our blog:

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

​What would 800 lumens equate to in incandescent wats? I couldn’t find a scale to show me how lumen output compares to incandescent wats, which is what I am used to when comparing light brightness. If I get two of these which are 800 lumen or 60W halogen will these give me essentially 1600 lumens on my painting surface (depending on the distance of course)?

​800 lumens is approximately equal to a 60-watt incandescent bulb. You are exactly right that two bulbs would add up directly to 1600 lumens and provide twice the brightness.

​Do keep in mind, though, that incandescent lamps emit a much warmer 2700K color tone, so it can be a bit difficult to compare brightness when discussing daylight-calibrated bulbs. Nonetheless, it is certainly a good ballpark estimate when it comes to relative brightness levels!

​There are so many different light sources to consider when creating a painting: reference source (photo, print, iPad, computer, life), natural outside light (weather dependent), studio light (intensity, color, placement including projection on both paintings and palette), photographing final work for publication and giclee printing, and gallery or home viewing of the finished painting. I read on your site that a device’s screen can emit blue light. So, is it probable that this is the first point where color can become distorted?

​That is exactly right - most digital displays will be calibrated to D65 (6500K) but of course, depending on the level of sophistication and quality, the calibration may or may not be accurate. Even natural daylight, as you mention, can change depending on the weather and season, so that can be difficult to navigate as well.

​That is where high-quality studio lighting comes in and can provide some consistency and accuracy. I have seen some customers even block out their windows and replace them with our lamps because the natural lighting was too inconsistent due to changing weather and time of day. Ironically, the only way to ensure consistent lighting would be to only use a high-quality, full-spectrum artificial light source, day and night.​

​If an artist is working primarily from an iPad should they choose the 6500K light because it matches the blue light from the iPad or goes with the 5000K because it will color compensate?

​Unfortunately, it does not seem that Apple likes to publish technical data about their iPad product and I was unable to confirm if their screens are calibrated to D65 (6500K). That being said, I believe almost all digital displays are calibrated to D65, so there is a strong likelihood that the iPad product line is also D65 calibrated.

​If so, the 6500K light source will be a better match to the iPad, since as you mentioned correctly, the 5000K will be a bit "warmer."

​(Here is some additional information on D65: https://www.waveformlighting.com/color-matching/what-is-d65-and-what-is-it-used-for)

​So many questions, but your team seems to have the technical expertise to answer them and for the various combinations of light. If these bulbs and your recommendations turn out to be the Holy Grail of Art Studio lighting, I would like to share it or see it as a feature article or workshop with my local, national, and international art society membership because many artists seem to struggle with this lighting issue because it is such a science complicated by the ever-changing variety of bulbs and diverse lighting comparison scales. Also, would you have any discounts available for our membership? 

We would be honored to have you share your experience working with our products! As a general policy, we do not offer any group or membership discounts, but I would be more than happy to share the opportunity with our team at that time.

Are the NorthLux 95 CRI T8 LED Tube Bulbs Dimmable? 

Are these NorthLux™ 95 CRI T8 LED Tube dimmable? Are you aware of any clamp-on, swing arm, or drafting table-style fixtures that would accept this 4' T8 bulb? I have a large 63" wide drafting table which I use for drawing/painting. I am looking for two clamp-on swing-arm style lamps which I can position on each side of my table to illuminate the whole surface evenly with one of your 5000k high CRI lamps. But am having difficulty finding the right fixture/lamp combination. 

Unfortunately, the NorthLux™ 95 CRI T8 LED Tube for Art & Studio products is not compatible with dimmers. Though we would love to recommend a compatible lighting fixture for your drafting table, we are unaware of any products which match the description provided at this time.

That being said, our NorthLux™ 95 CRI T5 LED Linear Light Fixtures might be of interest to you as well. Though these products are also not dimmable, they can be conveniently installed, are available in 5000K, and do not require fixtures or power supplies for functionality.

Please feel free to reach out if we can provide any further product information or recommendations, and we would be glad to help!

For your T5 Linear Fixture, how would you propose those be installed for my application? Do you have compatible clamp/swing arms to hold two or three in a desk lamp configuration? Or some other way to hold and manipulate them for drafting table use?

As the linear light fixtures can be linked together end-to-end to share one power supply, I imagine that a connected set could be mounted together as one length to an adjustable swing arm above the drafting table. 

​If a stable arm was found, we believe that the included mounting accessories could make such an installation easily re-configurable. Unfortunately, we do not have a specific clamp or swing arm that we could recommend.

However, you might also be interested in installing a length of LED strip lights onto a fixture above your drafting table. These products are compatible with dimmers and can be mounted within fixtures such as our Aluminum Channel for LED Flex Strip products. I have linked to a great article from our website below, which explains how to get started with LED strip light products.

LED Strip Lights - Everything you need to know before you buy: https://www.waveformlighting.com/led-strip-lights

How is the CRI of the LED strips affected when mounted inside the channel with the diffuser? 

Based on our experience, the diffusers do not affect the CRI values of the products mounted within. Further, we have found that the effect that this diffusor will have on color temperature is small, likely resulting in a difference of +/- 25 kelvin.

Choosing LED Lighting Allowed for TBI Conditions

I respond poorly to conventional LED lighting. As far as I can tell, my traumatic brain injury causes a response, not unlike that of an epileptic to the flashing of LEDs. The problem could be in the cold blue of the lights used in many commercial settings, or simply the intensity. Can you direct me to articles that will help me understand the problem — and choose bulbs? I am starting with a shop space and I am concerned that the 5000k fixtures you offer will be too white for my eyes. 

Our research and development for our products is generally limited in scope to the technical performance of the LED lighting system, so when it comes to their efficacy in a medical context, our data and ability to provide definitive answers is quite limited.

That being said, I do believe that you are definitely on the right track when attempting to determine the source of symptoms caused by LED lamps.

I have seen most studies link the flicker produced by artificial lighting to detrimental health effects, while the concern with blue light seems generally centered on circadian rhythm disruption.

Natural sunlight is essentially a flicker-free, 100 CRI light source that has a color temperature of 5000K or higher (depending on the season, time of day, etc). Does exposure to natural daylight produce those symptoms for you? If not, I would suspect the issue is more likely related to flicker, rather than color temperature and intensity.

In addressing your lamp configuration question, you are correct that installing our tube lights in a fixture will require some considerations to ensure fixture compatibility. One search that may yield some results is "LED ready T8 fixtures" as these fixtures are built and assembled without any ballast inside.

We are also looking to launch a line of LED ready T8 fixtures in the coming weeks so that could be an option as well.

Photophobia can be a real problem for some people with TBI, so they use sunglasses outside and in most indoor spaces. Somehow, most LEDs seems brighter than outdoor light to my eye, or to my brain. It may be that flicker creates irritation and calls my attention to the lights.

With your input, I am more confident that your 5000k shop lights will work for the space I have in mind. I will start with enough fixtures to test my response to them. I will also look into LED ready fixtures (that will support your 4000k bulbs).

​Your observation that most LEDs seem brighter than outdoor light is very much valid and I suspect the nuanced difference is due to the way in which the light is distributed.

​A single 800 lumen daylight bulb may produce far less light than natural daylight (i.e. "brightness") but the way in which the light is emitted from a very concentrated 1-2 inch sphere is quite unnatural and will most certainly appear brighter to the human eye. Contrast this with natural daylight, where the light falls down from an entire diffused dome of light, aka "the sky," and you can see why our eyes would react differently.

In short, the way in which the light is installed and distributed in your room may also have an effect on your perception and reaction to the lighting environment. For this reason, wall-washing and cove lighting (indirect lighting methods which bounce the light off of interior surfaces) are popular options that can provide a more comfortable space.

Shop Lighting for Auto Detailing

Would like to talk with someone regarding lighting for a shop for paint correction and also for home lighting fixtures we have.

Our 95 CRI LED products sound like a great fit for auto detailing.

​Our most popular product for such locations is our NorthLux shop light product, which I have linked to below:

Depending on whether or not you have existing T8 fixtures, our NorthLux T8 lamps may also be a good fit:

LED Bulbs Products for Color Control in Photography

I photograph (multi-shot/PS stitched) original art and maps for large-format reproduction. Have you gotten any feedback on the best product, bulb, or strip for better color control? I have fabricated light fixtures in the past and would appreciate advice on recommended reflector specs.

Based on the details provided, there are a few products that we might recommend.

For example, in the event that you were to utilize traditional E26 lamp fixtures, we might recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product.

However, if you were hoping to utilize traditional tube light fixtures, we might recommend the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product.

For more information regarding the D50 standard, this article from our website might prove to be useful:

Does the T8 LED Grow Lights compatible with T12 fixtures?

I am looking to purchase the T8 LED Grow Lights for my kitchen. I just wanted to ensure these would be compatible with the current fixture. Currently, my kitchen is lit by 4 Philips f40t12/CW supreme 40-watt bulbs. I believe this to be a T12 bulb. I've heard T8 and T12 are supposed to be interchangeable. However, I was unsure if the ballast capable of powering the current T12s might be too much voltage for these T8 grow lights I'm looking to replace them with. Would the T8 LED grow lights work as a replacement for the Philips f40t12/cw supreme? Ad if not, do you have a suitable grow light replacement for a T12? 

The T8 LED lamps will fit mechanically in your current T12 fixture, but the T12 fluorescent ballasts will need to be removed and/or bypassed.

​Instructions for how to perform the fixture rewiring can be found in the instructional manual below:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

​If you were interested in purchasing a new fixture all together, you may also be interested in our PhotonBlast fixture, which I have provided a link to below:

​

LED Grow Lighting for Garden Seed Starting

I've been looking at a number of LED lights for garden seed starting. I have a shelving unit 60"w 24"D and would like to purchase the appropriate number of light fixtures for each shelf and the correct 4000K or 6500K. What do you suggest? 

Our PhotonBlast fixtures are a great option for seedling growth in a vertical shelf unit. Each fixture is approximately 48" long, so even though your shelf width is a bit wider, the angular light distribution should provide sufficient coverage at the ends as well.

We would recommend perhaps 2-4 fixtures per shelf to provide sufficient coverage across the entire 60 x 24 inch surface. In my experience, it is always important to provide sufficient brightness during the seedling stage to prevent seedlings from getting "leggy" so that might be good to keep in mind.

We offer the product in both 4000K and 6500K (link below) and generally, 6500K works best for seedling growth, although I have also seen successful seedling growth with 4000K.

NorthLux 95 CRI T8 LED Tube for Painting Studio

I'm setting up my painting studio where I create realistic works, and I am looking at using your NorthLux™ 95 CRI T8 LED Tube for Art & Studio. What do I use to hook them up to? Do I purchase one for fluorescents and remove the ballast? A wraparound will look nicer than bulbs, but does it affect the CRI? Also, I have to purchase 4 from you, but I believe 2 will be enough for my space; the room is approx 13' x 15', with a double Easterly window and a single Southerly one. 

Our NorthLux T8 LED lamps sound like a great option for your art studio! As you mention correctly, these T8 lamps require a 4-ft fixture housing. Most fixtures that are available today do indeed have fluorescent ballast, so we would recommend removing the ballast and rewiring the fixture to ensure compatibility. Once the ballast is removed, the T8 lamps can be installed directly.

As long as the diffuser cover in the fixture is transparent or semi-transparent (as opposed to having a colored tint), there should be no effect on the light quality and will not pose any problems from a color accuracy perspective.

​Finally, I've plugged the dimensions of your space into the lumen estimation calculator which you can find at the link below:

https://www.waveformlighting.com/lumen-calculator

The suggested brightness level to achieve 80 footcandles (recommended for art studios) is 15,722 lumens. Based on this lumen output target, we would recommend up to nine of our T8 lamps. (Your initial estimate for just two lamps may have been based on lower brightness needs in line with a residential space).

Is the 1800-lumen of T8 LED Tube for one lamp?

I need to know that 1800 lumens output using 18W power consumption is meant for 1 pc, or 4 pcs. / LED tube No rthLux ™ 95 CRI T8 for Art & Studio. I need lighting for an art studio measuring 3m x 4m ceiling height of 2.8m. What do you recommend? 

The 1800-lumen measurement is for one lamp.

I plugged the dimensions of your art studio space (converted to feet: 10 x 13 x 9 ft) and received a result of 10,589 lumens as the recommended brightness for your space.

Since each of the 4-ft lamps emits 1800 lumens, you will want approximately 6 lamps to provide sufficient brightness.

Using just four lamps would provide you with 7200 lumens, which will be an acceptable level of brightness for most tasks, but perhaps for more visually intensive tasks, you may want to increase the brightness as our calculator tool suggests.

Recommended quantity of LED Lights in building an Art Studio

I am building an art studio. It is 3000 square feet. I am dividing it into two distinct spaces: the shop with a full complement of woodworking machinery, and a clean studio for drawing, painting, and other quiet work. 

I have calculated that I need 16 of PN:4025. Is this the proper fixture and quantity?

​I've run these numbers in our lumen estimation calculator and received a recommended brightness level of approximately 65,000 lumens. Since each of our PN 4025 shop light fixtures emits 4200 lumens, my math also works out to approximately 16 lamps, which lines up perfectly with your calculations.

​Is there an alternate fixture for the purpose?

​I do not believe that any other fixture options would be superior, except for our T5 linear fixtures, if these are perhaps a more preferred option from an aesthetic or layout perspective. I have included the link to the product below:

​Similarly, we offer a T8 LED tube light which can be used in traditional fluorescent fixtures. It does sound like you are building a new structure, such that utilizing previous-generation fluorescent fixtures would not make much sense unless you had a particular reason for doing so.

​The color quality at 5000K / 6500K and 95 CRI are identical across all of these options so that should not affect the decision in terms of form factor.

​Now on to the shop side of the studio. I am not sure of the lighting level appropriate for a woodworking space. Is it 30fc (simple manufacturing and industrial) or 40fc (like a classroom)? I have been planning on using 25 at 4000-lumen LED fixtures made by Hyperikon. These lights are 84 CRI and produce 40fc over the area. They are under $20/fixture. Is there justification for purchasing your lighting for the shop side of my studio instead of theirs?

​This is a bit difficult for us to provide any definitive guidance on the 30 or 40 footcandles would depend on the exact level of precision needed, as well as the type of wood, along with personal preference on brightness.

​It is certainly possible that 30-footcandles just don't provide enough brightness, but I would not think that going with 40-footcandles would be "too bright" (i.e. uncomfortable) by any means, so the worst-case scenario here would be that we are over-specifying in terms of brightness.

​As with the brightness question, the higher CRI rating may or may not be necessary depending on the type of woodworking. Some of our customers find that the ability to make very critical color observations during woodworking (perhaps during staining or other visually demanding processes) justifies the additional cost. On the other hand, if color accuracy is less of a concern, I would perhaps recommend staying with the 84 CRI fixtures as that would be more than enough to simply "see" what you are doing and complete basic tasks.

​Do I have a good amount of light coverage, or would I need more? 

I'm not sure what the dimensions of your woodshop will be, but the 25x Hyperikon fixtures would provide you with 100,000 lumens which would be sufficient for approximately 2200 square feet of coverage.

Do you have a 4-ft full spectrum bulb suitable for T12 fixtures?

I have two 4-ft spectrum bulbs that are getting old they are fluorescent (TRU LIGHT ULTRA F40T 12TLU). I don't know if I need a fixture or not.

It appears that you currently have a T12 fluorescent lamp in a 4-ft T12 fixture. The good news is that our T8 lamps will fit in your existing fixtures, but the existing fluorescent ballast will need to be removed or bypassed.

​Once the ballast removal or bypass is complete, you will be able to use our T8 LED tube lights in the same fixture. 

Does the NorthLux 95 CRI LED Shop Light Fixture come with the tube lights?

Does the Northlux 95 CRI LED Shop Light Fixture 4025.50 come with the tube lights already? How many lights are on the fixture and which replacement lights do I order? 

Yes. We can confirm that the NorthLux™ 95 CRI LED Shop Light Fixture is an integrated product that contains the lighting units pre-installed. This product is designed with two lengths of applied lighting products within the housing and does not utilize traditional T8 tube lighting.

After the warranty is up after 3 years and the lights go bad, are the lights replaceable? If so which ones? 

The lighting units within the fixture are unfortunately not replaceable, as they are designed to be fully integrated into the product housing. As such, if the lights within the product fail, the full unit would require replacement.

If a fixture with swappable lighting units is preferred, we might recommend utilizing a third-party T8 light fixture with our LED tube light products such as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light. These products also feature a 3-year warranty and can be easily replaced if they experience failure or malfunction.

What is the benefit of purchasing the lighting units that are built into the fixture over purchasing a light fixture with swappable lighting units? I notice you have both. I'm trying to decide which one is best for me. I'm an artist and need good overhead lighting.

Our T8 LED tube light fixtures can be beneficial for installations where a customer prefers to use pre-existing retrofit fluorescent fixtures. For some spaces such as offices or rental areas, replacing ceiling lighting is more difficult than simply replacing the lighting within the fixtures.

Further, some customers prefer to have the flexibility of changing the color temperatures of the lights within the fixtures.

Alternatively, some customers prefer to have a dedicated color temperature light that can be easily installed and replaced as a whole unit. Customers who are working in garages, studios, and other retrofit areas might prefer such a product that allows for flexibility without installing a permanent fixture.

Is any retrofitting required for T8 LED Grow Light Tube installation?

I want to use the PhotonTube™ T8 LED Grow Light Tube in a fluorescent fixture. Is any retrofitting required, or do I merely use this bulb as a replacement without re-wiring/ballast changes? 

Our T8 LED tube lights can fit into all fluorescent fixtures that are 4 ft in length. So, if you can confirm that your existing fluorescent fixture is 4 ft in length, we can be quite certain that our T8 LED tube lights will fit!

​In terms of the electrical connections, you will want to check if the fluorescent fixture has a ballast inside. If the fluorescent fixture contains a fluorescent ballast, you will want to check that it is listed on our list of fluorescent ballasts, which can be found at the link below: 

https://www.waveformlighting.com/datasheets/UM_4024.pdf

If the fluorescent ballast is not listed, you will want to remove or bypass the ballast from the fixture.

Choosing between Shop Light Fixtures and T8 LED Tubes for Art Studio Lighting

I’m a painter looking for shop lights for my art studio, and I’m trying to decide between purchasing your Northlux 95 CRI LED Shop Light Fixtures or your NorthLux 95 CRI T8 LED Tubes for Art & Studio. I have several questions: 

In terms of lighting an art studio, do you recommend one of these options over the other? Is there a difference in the quality of light they provide?

Our daylight color temperature products are a great fit for an art studio, and generally speaking, all products under our "NorthLux" brand would be an excellent fit.

As you mention, however, many of the lighting requirements for artwork and other applications, such as studio photography, do overlap quite a bit. As such, you may see several of our products which are listed on separate product pages even though the underlying product is the same. (Please see my response to your question below about the CENTRIC DAYLIGH vs NorthLux, for example).

And if you recommend I purchase the LED tubes, is there a hanging fixture you recommend that will work well with them?

​We don't have any specific recommendations, and it is a bit difficult to locate compatible fixtures since many fixtures available on the market today are geared towards fluorescent lamps and not LED lamps.

Our LED lamps can be used with fluorescent fixtures as long as they either contain a compatible fluorescent ballast, or the fluorescent ballast is bypassed.

​We would recommend performing a search for "LED ready" fluorescent fixtures or consider the shop-light style LED fixtures you mention below.

Does the Northlux 95 CRI LED Shop Light Fixture have a frosted cover on it? Or is the cover clear, exposing the LED strips?

Our previous batch of shop light fixtures did not have a frosted cover, so the photos you see on the website will also reflect this and show the individual LED diodes. Our new batches, however, have a frosted cover, allowing for a more diffused and distributed light output.

What is the difference between your Centric Daylight and Northlux lines? Would the Centric Daylight tube lights also work well in an art studio?

​Both the CENTRIC DAYLIGHT and NorthLux product lines have the same underlying technical specifications. As mentioned above, these product markets have identical or very similar lighting requirements and the products can be used for either application.

The best way to confirm whether products are identical or not would be to check the part numbers listed under the product name on each product page.

I noticed that the Centric Daylight tube lights are flicker-free, which sounds great. Do the Northlux lights have a flicker? 

​The NorthLux lamps are also flicker-free, so that would be a nice benefit for an art studio as well (even though we are not actively marketing it as such at the moment).

If I order the light fixtures now, will the ones I receive have the frosted cover? In case it makes a difference, I plan on getting a six-pack of the 5000k ones. 

Yes, any orders placed now or in the future for the NorthLux shop light fixtures (5000K) will have the frosted cover on them.

Just to clarify, is the entire NorthLux line of products flicker-free, including the shop light fixtures?

The new 5000K fixtures are both flicker-free and have a frosted cover.

In case the shop light fixtures don't work out for me, is it possible for Waveform Lighting to schedule a pickup for the return from my home? I'm located in California. 

We offer free return shipping via a pre-paid USPS Priority Mail shipping label. USPS offers complimentary pickup at most residences so if this works for you, we should not have any issues accommodating the pickup request!

Is it safe to plug the shop light fixtures into an extension cord, even when daisy-chaining multiple fixtures? My studio ceiling is very high and the 60-inch power cable won't reach any outlets without an extension cord.  

Yes, as long as you do not exceed the amperage rating on the extension cord, you should not have any issues. The amperage is calculated based on the individual amperage ratings of each fixture (0.4 amps) multiplied by the number of fixtures you plan on daisy-chaining.

For example, four fixtures would have an amperage of 1.6 amps (0.4 amps x 4 fixtures) so you will want to make sure the extension cable has a rating that exceeds 1.6 amps.

Replacement T8 LED Tube Light Output Equivalent

I'm looking for replacement tubes for my kitchen light, which currently has 4x 2900 lumen 40W T12 fluorescent tubes. I'd like to purchase your 48" CENTRIC DAYLIGHT Tubes, however at 1800 Lumens and 320 light distribution angle, I am concerned they won't be bright enough. However, the spec sheet says they are comparable to a 40W bulb. Since there is only one light fixture, and I do not intend to add another, I need clarification on the bulb brightness before I can make this purchase.

We can confirm that our T8 LED tube light products offer an output of 1800 lumens per light. As such, it does appear that the output may be less than your current tube lights.

However, please note that we offer a 30-day return policy. If these items wind up not working well for your space, simply let us know and we would be happy to issue a prepaid return label so that they can be returned for a refund.

Choosing between T8 LED Tube and LED Strips for an Existing Electrical Boxes

I'm trying to choose between tube and strip lights and I need info on how I can hook it into my existing ceiling outlet box. 

While each installation can differ, we generally recommend using our LED tube lights if there is an existing 4-ft fixture already in place. Our LED tube lights can be used without a ballast and therefore can be used without any additional electronic components.

LED strip lights, on the other hand, can provide you with some additional versatility and installation options. This approach, however, will require additional wiring and configuration, including power supply units and LED strip assembly.

I have six separate track lights on separate dimmer switches. The reasons they interest me are that they look to be very low profile and you have a 99 CRI strip light but only 95 CRI tube lights. Are there any other advantages or disadvantages I should be aware of for strips vs ubes? If I go with the strip light option, what do I need to do? How does it connect to the end feed and will the extra transformer fit inside the end feed? Will I need new dimmer switches? I currently use these(Lutron CTELV-303P-WH Skylark Contour 300W Electronic Low Voltage Single Pole / 3-Way).

Since you don't have a fluorescent fixture at all, the LED strip light option is definitely worth considering.

The challenge with installing an LED strip light in a location like this is that the existing track systems operate at a completely different voltage type and level. Typically, they are 120 volts or 12 volts AC, while the LED strip lights require 12 volts DC.

As such, the electrical wiring and systems inside the track lights will not be useful here and will need to be bypassed completely.

Below is a configuration diagram for a simple LED strip setup:

You will see the TRIAC dimmable power supply, which is the key component here that you will want to determine where you can fit this in your current installation. It is a somewhat bulky device and you will want to ensure it is installed in a location compliant to local electrical code. (Most frequently, it is installed inside of a junction box mounted inside of the wall).

The TRIAC power supply appears to be 9 inches, so it won't fit in the current electrical box in the ceiling. Could I just purchase your junction box and attach it to the ceiling? Do you sell it in white? Alternatively, I could install the TRIAC in the attic near the switches, but then it would need to feed into the current wires that run to the ceiling position. I'm thinking that those standard wires must be different than the ones needed for the DC, is that right? If so, I guess the TRIAC has to go right next to the strip lights. 

We are not sure about the electrical code requirements and considerations of mounting the junction box on the ceiling, so that is something you will want to confirm before going down that path. The junction box is unfortunately not available in any other colors.

The concern with installing the TRIAC dimmable power supply far from the LED strip lights is that large distances between the power supply and LED strip lights can result in voltage drop, whereby the brightness of the LED strips become diminished by the reduction in voltage supply. Generally, we recommend keeping the LED strip sections within 32 feet of the power supply unit to reduce the impact of voltage drop.

My understanding is that your tube lights are not dimmable, is that correct? 

That is correct. We agree that the LED strips would be the best option for a dimmable + flicker-free lighting solution.

​Do you sell L pieces for the aluminum channel so I can turn corners with the flex strips?

Unfortunately we do not sell any "L" shaped corner pieces. The best way to accomplish this would be to solder wires directly between the LED strip segments that meet at the corner. The aluminum channels can also be cut at 45-degree angles to create a gapless 90-degree turn.

​Do I need the centric series power supply rather than the triac to get flicker free? 

​The most recent batch of TRIAC dimmable power supplies is also now rated flicker-free. Therefore, you will be able to use the TRIAC dimmable power supply and achieve flicker-free and dimmable light output.

​Do you sell a junction box that covers the centric? 

​We do not sell a junction box for the CENTRIC SERIES power supply. We would recommend going with the TRIAC dimmable power supply since it also provides flicker-free light output.

Can I connect two separate 8 foot strips to one power supply? 

Yes, they can be connected "in parallel" - please see the blog post below:

https://www.waveformlighting.com/home-residential/connecting-led-strips-in-series-vs-parallel

I'm just about ready to order the absolute strip. I'm still trying to decide on whether to go with 6500k or 5000k. What connector will I need for that? 

Both the 5000K and 6500K should be good options for you. Here is an article, in case you haven't had a chance to yet see it, that might help you make a more informed decision one way or another:

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Once the LED strip is cut, it cannot be re-joined using the pre-mounted female DC cables. They can be re-joined using the PN 3071 accessory that you have correctly identified.

Full Spectrum LED Lights for Home Gym and Film Studio

I am converting a barn into a home gym that will also be used as a film studio to create content. I've been told that full-spectrum LED lights would be ideal. Hoping you can guide me to determine if your products are right, and which ones to choose. 

Based on the details that were provided for your gym and studio space, there are a few products that we might recommend. We would be more than happy to provide further details and advice about each product mentioned upon request, as well.

For example, we sell the NorthLux™ 95 CRI LED Shop Light Fixture, which is a great option for installations where non-permanent lighting options are preferred, as it can be easily re-arranged and mounted using the included hanging chains and hooks. This integrated product requires no accessories and can be daisy-chained with other units, but it is unfortunately not compatible with dimmers.

If you would prefer to utilize new T8 tube light fixtures in your space to have the benefit of easily swappable lighting, we might recommend the NorthLux™ 95 CRI T8 LED Tube for Art & Studio products.

Further, we also offer our LED strip light products. As an overview, these products are sold in reels and are compatible with in-wall power connections and wall dimmers. These strip lights can be configured in multiple ways and can be mounted using products such as our aluminum channels. These lights are also compatible with third-party lighting systems such as Lutron Caseta.

For more information regarding our LED strip lights, we have attached an article from our website below.

LED Strip Lights: Everything you need to know before you buy: https://www.waveformlighting.com/led-strip-lights

By using our lumen estimation calculator tool, we estimate that the space described would be fully illuminated by 18,821 lumens. As each product emits a different amount of light, we might recommend either 5 LED shop light fixtures (at 4200 lumens emitted per fixture), 11 T8 LED tube lights (at 1800 lumens emitted per light), or 42 feet of LED strip lights (which emit 450 lumens per foot) for your space as options.

5000K Lighting for Oil Painting Studio

I just found your website and would like to purchase an LED tube light for my oil painting studio, but noticed that your NorthLux™ 95 CRI LED Shop Light Fixture is sold out until 2-1-21. This sounds like the best option for me, but could you recommend an alternative? I'm noticing that you have T8 bulbs that would work with a regular fluorescent fixture. Could you point me to a fixture that would work well with these bulbs? Or is the NorthLux™ 95 CRI LED Shop Light Fixture a much better solution because of the diffuser and the integrated LED tubes? I'm interested in 5000K, but maybe you could suggest why I would want to go to 6500K?

We can confirm that our LED Shop Light Fixture is a great option for your lighting needs. You may take advantage of our 30-day return policy if you would like to try the product in your studio.

We can also confirm that our T8 LED tube light products can be utilized in any existing T8 fixture, though we do recommend installing these products within fixtures that do not utilize ballast or bypass the ballast entirely. More information about these installation types can be found on our T8 product specification sheet, which I have linked below.

Specification sheet link: https://www.waveformlighting.com/datasheets/UM_4020.pdf

We also have a terrific article on our website which describes the differences between 5000K and 6500K in detail, which might prove to be useful in your planning.

Difference Between 5000K and 6500K Bulbs: https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Do you sell 5000K light bulbs for track lighting? See attached image. I probably need to get you some sort of code off the bulb itself. See attached image.

Based off of the photo that was shared, it appears that the lights within your track system are BR30 bulbs​.

We're happy to confirm that we sell the 5000K Full Spectrum E26 BR30 LED Bulb products, which are often installed within similar track lighting systems. This product also features compatibility with dimmers.

T8 LED Tube Lights for Grow Shelf Installation

Can you please let me know your answers to the 3 questions below? We need to order 8 of these tubes today to make sure we can use them in time for our project. 1) How many lumens? 2) Are there instructions for ballast removal & wiring that come with this item? 3) For a 22" x 48" growing platform, will four tubes provide enough light? 

Our T8 LED tube lights sound like a great option for your grow shelf installation. Below are answers to your questions:

1) How many lumens?

Each lamp puts out 1800 lumens.

2) Are there instructions for ballast removal & wiring that come with this item?

Yes, an instruction sheet will be included in the product, and can also be located at the link below:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

3) For a 22" x 48" growing platform, will four tubes provide enough light?

​For most plant types and early-stage growth, the four lamps would be the minimum we would recommend. Ideally, we generally recommend installing 100 watts or more for sufficient coverage. At 18 watts per lamp, this would work out to six lamps or more per shelf.

​As an alternative, we may also recommend our PhotonBlast fixture. Two of these lamps can provide nice coverage of a 22 x 48 shelf. Please see below for the product link:

T8 Full Spectrum LED Lights for Automotive Paint Booth

I own an auto body shop and I just bought a new paint booth and was researching lights. It has 10 light fixtures which take 4 bulbs each. It requires T8 bulbs(4ft). From my research, I think I should buy full spectrum 5000K bulbs. What product do you think fits my needs? 

Based on the details provided, we believe that the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product could be a great option for your paint booth.

The 5000K color temperature option is what we generally recommend for industrial installations and color evaluation purposes, which can be noted in the article below:

Which LED Light Color Temperature Should I Choose: https://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose

However, please note that we are happy to offer a 30-day return policy. If the 5000K option winds up not working for your space, simply let us know and we will issue a prepaid return label.

Photon Series Full Spectrum LED Grow Lights for Horticulture

I am trying to order (2)- Photon 2000 Series Full Spectrum LED Grow Lights. I can't seem to find them on your website.

We regret to inform you that the Photon 2000 Series product is currently discontinued.

We, unfortunately, don't have anything similar, but the closest options for horticulture would be our PhotonBlast, PhotonTube and our PhotonPanel products. Please see the product links below:

LED Tube vs Strip Lights: Which should I choose?

I'm trying to choose between LED Tube and Strip Lights, and I need info on how I can hook it into my existing ceiling outlet box. 

While each installation can differ, we generally recommend using our LED tube lights if there is an existing 4-ft fixture already in place. Our LED tube lights can be used without a ballast and therefore can be used without any additional electronic components.

LED strip lights, on the other hand, can provide you with some additional versatility and installation options. This approach, however, will require additional wiring and configuration, including power supply units and LED strip assembly.

I actually have six separate tracks on separate dimmer switches. They connect to the ceiling wiring through the standard round plastic end feed box that is recessed into the ceiling. Are there any other advantages or disadvantages I should be aware of for strips vs tubes?

If I go with the strip light option, what do I need to do? How does it connect to the end feed and will the extra transformer fit inside the end feed? Will I need new dimmer switches? I currently use these (Lutron CTELV-303P-WH Skylark Contour 300W Electronic Low Voltage Single Pole / 3-Way).

Since you don't have a fluorescent fixture at all, the LED strip light option is definitely worth considering.

The challenge with installing an LED strip light in a location like this is that the existing track systems operate at a completely different voltage type and level. Typically, they are 120 volts or 12 volts AC, while the LED strip lights require 12 volts DC.

As such, the electrical wiring and systems inside the track lights will not be useful here and will need to be bypassed completely.

Below is a configuration diagram for a simple LED strip setup:

https://www.waveformlighting.com/layoutmaps/3001_1A

You will see the TRIAC dimmable power supply, which is the key component here that you will want to determine where you can fit this in your current installation. It is a somewhat bulky device and you will want to ensure it is installed in a location compliant to local electrical code. (Most frequently, it is installed inside of a junction box mounted inside of the wall).

The TRIAC power supply appears to be 9 inches, so it won't fit in the current electrical box in the ceiling. Could I just purchase your junction box and attach it to the ceiling? Do you sell it in white?

Alternatively, I could install the TRIAC in the attic near the switches, but then it would need to feed into the current wires that run to the ceiling position. I'm thinking that those standard wires must be different than the ones needed for the DC, is that right? If so, I guess the TRIAC has to go right next to the strip lights. 

Do you all plan to offer tube lights with 99 CRI soon?

We're not sure about the electrical code requirements and considerations of mounting the junction box on the ceiling, so that is something you will want to confirm before going down that path. The junction box is unfortunately not available in any other colors.

The concern with installing the TRIAC dimmable power supply far from the LED strip lights is that large distances between the power supply and LED strip lights can result in voltage drop, whereby the brightness of the LED strips become diminished by the reduction in voltage supply. Generally, we recommend keeping the LED strip sections within 32 feet of the power supply unit to reduce the impact of voltage drop.

​We are hoping to be able to incorporate our 99 CRI LED technology in our LED tube lights in the future, but we do not have any firm release dates on that at this time.

Do your T8 tubes directly go into T12 fixtures as replacements?

Do your T8 tubes directly go into T12 fixtures as replacements? How are the Sidewinder bias strips daisy chained? Are there connectors supplied, and is soldering required?

It sounds like you currently have 4-ft T12 fluorescent lamps. If so, our T8 LED tube lights can be used in the same fixture, as long as the ballast is either bypassed or completely removed. (The new T8 LED tube lights are NOT compatible with T12 fluorescent ballasts, and should be wired directly to line voltage).

For further instructions on installation and wiring, please reference our installation manual:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

As far as the SideWinder product is concerned, located on each end of the LED strip reel is one male DC jack and one female DC jack. As such, no special components or accessories are needed if you are looking to simply daisy-chain the LED strip light reels in an extended run.

NorthLux T8 LED Tube Lights for Art Studio

I presently have fluorescent tubes in my art studio I have 2 ceiling flush-mounted units, each with 4 fluorescent bulbs of 40 watts each. How many of your LED tubes do I need to replace the light of 8 fluorescent 40-watt tubes? Also, can I install these new LED tubes into the fluorescent unit that houses 4 tubes and has a ballast? I do not want to use the ballast anymore as it is over 30 years old and hums make the fluorescent lights flicker.

Our NorthLux T8 LED tube lights sound like a great fit for your lighting upgrade project.

It sounds like you currently have 4-ft T12 fluorescent lamps. If so, our T8 LED tube lights can be used in the same fixture, as long as the ballast is either bypassed, or completely removed. (The new T8 LED tube lights are NOT compatible with T12 fluorescent ballasts, and should be wired directly to line voltage).

Since you mention that the existing ballasts are old and in need of replacement, hopefully this should not be too much of an inconvenience. Additionally, the flicker-free feature of our LED T8 lamps should provide you with a very nice improvement in the lighting environment.

For further instructions on installation and wiring, please reference our installation manual:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

In terms of brightness, each one of our T8 LED tubes will produce the same or slightly more light than a T12 fluorescent tube. As such, if you felt that the existing 8 fluorescent tubes provided you with sufficient brightness, a one-to-one replacement with 8 of our T8 LED tube lights should be a good starting point.

Recommended LED Lights for Breeding Dogs

I have breeding dogs in 5 x 5-foot dog kennels in a shop with 20-foot ceilings, which have 4ft 4 bulb lighting across the whole ceiling. The room is approximately 60 ft x 72 ft with the kennels occupying about 20 x 30 ft long along one wall. What lights should I use? Should I install a light shield over the tops of the kennels to defer the ceiling lights when the shop is being used regularly on our farm? Is this going to have a noticeable effect considering the ceiling lights? 

While lighting applications for animal health are beyond the scope of our expertise, we would be more than happy to assist with general recommendations for creating a lighting environment that best mimics natural light.

We would perhaps suggest starting with a target illumination level of 150 footcandles. This would require approximately 3700 lumens per 5 x 5 ft kennel.

Our most popular product is our flicker-free T8 LED tube lights. These lamps can be housed in 4-ft lamp fixtures and feature flicker-free, full-spectrum light output at 95 CRI. Please see below for the product link:

Each lamp emits 1800 lumens, so for each kennel, you will want to use two or more lamps per kennel.

Alternatively, our BR30 lamps can also be used if you have standard, circular ceiling fixtures:

These lamps emit 800 lumens each, so you will want to use approximately 5 lamps per kennel.

Are your LED Bulbs compatible with American Fluorescent Fixtures?

The light fixture I have for this size tube is made by American Fluorescent. Just wondering if this fixture might have proven to be compatible with your light since the list was made.

We're happy to confirm that our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products is compatible with enclosed light fixtures. However, our other A19 bulbs will require a moderate amount of airflow and heat dissipation which the enclosed fixture may be unable to provide.

We can also confirm that our T8 LED tube lights are compatible with existing T8 fixtures. However, our T8 LED tube lights may not be compatible with the ballasts within all fixtures. Below is a link that contains the list of compatible ballasts.

Tested ballasts: https://www.waveformlighting.com/files/CD4020.txt

If the ballasts are not compatible, there are alternative installation methods described within the product specification sheet, such as ballast bypass, which could prove to be valuable.

I was more interested in the A19 Bulbs, and I see in your description that they cannot be used in enclosed fixtures (Centric Daylight, NorthLuz, and D50).

Unfortunately, each of the products listed requires some amount of enclosure airflow so that the heat generated by the bulb can dissipate.

Without adequate heat dissipation, the electronic components within the LED products can be prone to error.

Are the NorthLux T8 LED Tube Lights compatible with new T8 fixtures?

I will be purchasing new fixtures for the studio I'm renovating. They will be 4' long, with two lamp fixtures each. My question is: Can the NorthLux T8 Tubes be used in newly bought LED wired/ready T8 fixtures instead of using the tubes as a retrofit for existing T8 fluorescent fixtures? 

We're happy to confirm that the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product is compatible with new T8 fixtures as well as older retrofitted fluorescent fixtures.

Listed below are three fixtures I'm considering (cost and ease of purchase being the two main deciders). But if there is a recommendation you can make outside of these three fixtures I'm all ears!

Maxlite LSS2XT8USE4803 75303, Nicor 10395EB, Lithonia C 2 32 120 GESB

Using your online lumen calculator, I come up with 19 lamps needed for my 400 sq ft space (ceilings are 8 ' high). So I am looking to do 10 fixtures in this case.

After some review, it appears that each of the lighting fixtures provided is compatible with our NorthLux™ 95 CRI T8 LED Tube for Art & Studio product.

However, it might be helpful to know that the Lithonia and Nicor products utilize ballasts, which can cause some performance issues if the ballasts are not compatible. That being said, there are instructions for installing our tube lights into ballast fixtures using a ballast-bypass method, which is described on the product specification sheet.

Here is a link to our list of compatible ballasts: https://www.waveformlighting.com/files/CD4020.txt

Further, the Maxlite fixture does not appear to utilize a ballast, though the instruction manual for the product does state that it is only compatible with “MaxLite LxxT8SE4xx lamps”. You may want to check with the manufacturer to see if that information is accurate.

Is there a way to cross reference that list with actual fixtures that have those listed ballasts installed in them? When I Googled some of the listed ballasts all I got were web pages for the actual ballasts, not the ballasts as installed in fixtures. 

While such a tool would certainly be helpful, unfortunately we do not currently have a way to cross-reference compatible ballasts and light fixtures. We apologize!

Dimmable T8 LED Tube Lights for Art Studio Lighting

I am interested in the CRI 95 5000K Northlux LED Tube, but I need a dimmable one if possible. 

Unfortunately, our T8 LED tube light products are not compatible with dimmers.

However, our LED Strip Light products are compatible with dimmers and could prove to be a valuable alternative depending on your installation.

I decided to, for now, purchase several packs of the 4000K CRI 95 Centric Daylight Bulbs. What is the R rating for these bulbs?

We have attached the photometric report for the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs below, which lists the R values.

Photometric report link: https://www.waveformlighting.com/photometrics/TR_4005.40.pdf

Choosing LED Northlux vs Centric Daylight for Painting Studio

I have a question about choosing Northlux 95 CRI bulbs vs the Centric daylight full spectrum bulbs either in 5000K. 

I am using these lights in a painting studio so I'm looking for high as possible color quality as can be. I also read your site said if I care more about a CRI I should use a fluorescent fixture choosing one of those bulbs above which fixture below would suggest for my situation and how many fixtures of each would you suggest to obtain the ideal illuminated result in the painting studio? Further information to give more background in my situation. I have a 12" x 16" space with 15-foot ceilings and I will be making work on both 12-foot walls as well as one 16-foot wall. 

The primary difference between the 5000K A19 bulbs can be found in the CIE D50 standard which the NorthLux product was designed to be compliant with. This is an international color standard which many find value in, due to the low amount of variability in light spectrum output across compliant products.

Here is a great blog post from our website which explains this standard further, which might be helpful: https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

However, in the event that you would prefer to utilize a T8 LED tube light fixture, I am happy to confirm that both fixtures provided appear to be compatible with our products.

The two LED tube light products that I recommend for your studio are the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000), and the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. The D50 5000K option has a higher R9 rating than the NorthLux (95 vs 91), which could be beneficial for working with color.

Based on my calculations using our lumen estimation calculator, it appears that your space would benefit from 15,981 total lumens. As each of the T8 LED tube lights emits 1800 lumens, we recommend 9 lamps in order to sufficiently illuminate the space.

Do you have a commercial high-bay/suspended-type lights?

We are building an addition to our brewery and would like to know if there are commercial high-bay/suspended-type lights for a taproom and brewery space.

Our high CRI and full spectrum lamps sound like. a great option for lighting up a brewery and providing a high-end lighting atmosphere.

For high-bay installations, the first aspect would be to consider what type of fixture you would like to utilize for the space. If, for example, you have existing T8 fixtures, our T8 LED lamps may be a great option for such retrofit applications: https://store.waveformlighting.com/products/centric-daylight-full-spectrum-flicker-free-t8-led-tube-light

Alternatively, if you do not have any fixtures in place (or if this is for a new build), you may want to consider our hanging shoplight fixtures or our integrated T5 fixtures. These products have LEDs integrated into the fixture, so there is no need to purchase the fixture and lamps separately. Please see below for additional product information:

Difference between the NorthLux and D50

I am interested in purchasing some light bulbs for a fixture being installed in my studio to supplement our North light window into the evening hours. I am looking at the NorthLux and D50 bulbs and wondering what the distinctions between the two bulbs are. It seems the NorthLux is best suited to our needs, however, our electrician is recommending the D50. 

Our NorthLux products are offered in both 5000K and 6500K. The 6500K color option is likely to be an excellent match for the natural light you currently have coming in from your north-facing window. Some visual artists and other professionals do prefer 5000K as it provides a bit less blue and is a more neutral color point.

For additional insights into the difference between these two color temperatures, please see below:

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Our NorthLux products in 5000K are actually the same product as the D50, and the products are listed on multiple product pages for marketing purposes. We do apologize for any confusion caused!

LED Panel Lights for Home Office Lighting

The space my wife and I use as a home office was originally designed as a sun porch. There's a single, small fixture in the middle of the room that provides very poor lighting to our desks. I was thinking of installing a surface mount LED panel (because the ceilings are relatively low) over each desk, but it's difficult to find LED panel lighting with >80 CRI. I'm looking for something that mounts close to the ceiling, is dimmable, and relatively long (to provide even lighting across a desk).

We unfortunately do not have any LED panel lights, and the requirement for dimmability makes this quite challenging based on the offerings we currently have available.

If you're willing to forego dimmability as a requirement, our T8 LED lamps housed in an appropriate ceiling fixture, or our T5 linear fixtures, could potentially be viable solutions for you. Both are available with 95 CRI and provide excellent light quality that should work well for a home office.

​I've included product links for these products below:

Can I order six of the T8 LED Tube Light?

I need six, 48" full-spectrum tubes to replace florescent bulbs. Can I get six? Does it matter if the fixture has a ballast?

While we're happy to confirm that our full spectrum T8 LED tube light products are 48” in length, these products are currently only sold in quantities of 4-Packs and 24-Packs.

As such, we are unfortunately unable to fulfill an order containing only six units of these products.

However, we can confirm that our products are compatible with many ballast models. I have attached a link below, which lists the ballasts which have been tested and are compatible with our T8 LED tube light products.

Compatible ballast list: https://www.waveformlighting.com/files/CD4020.txt

That being said, we have found that our T8 LED tube light products typically work best when installed within fixtures that have had the ballasts removed, or when they are installed using the ballast-bypass method. The below link provides instructions on this process, in the event that it proves to be useful.

Product specification sheet: https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

D50 T8 LED Tube Lights for Color-Matching

We are looking for D50 Daylights for our color-matching table for printing and Packaging film checking. With the currently installed daylights we are facing an issue with online approval of our printing substrate through video calls there is flickering in the video and the other person on the video call is not able to see the substrate. Same problem we are not facing with normal light. So we are looking for such day lights which work fine with video transfer.

Currently, we use fluorescent tubes with electronic ballast of 36 watts, lengths of 1200mm, and 5000K. 

Based on the 5000K and 1200 mm length specifications, I've determined that our T8 D50 lamps are the best option for your needs. Please see below for the product link:

​We will also need to check for electronic ballast compatibility. The ballast must be listed on our list of compatible ballasts (found here: https://www.waveformlighting.com/datasheets/UM_4024.pdf) for safe operation. If the ballast is not listed, you will need to perform some fixture modifications to remove or bypass the ballast altogether.

I want to confirm about the flicking issue we are facing with the existing light at the time of video calls will not be there with this T8 D50 lamps please advise. For electronic ballast, we can bypass if your LED lamp is not required the same.

Yes, these lamps are flicker-free when used without a fluorescent ballast (including an electronic ballast bypass). This would include video conferencing applications.

Please provide the datasheet for the light Certified that the provided light is D50 lights.

We have attached a link to the product photometric report below, which displays the full product light output technical details.

High CRI LED lighting for Photographic Printmaking

I am a professional printmaker for photographers who sell their work in galleries. I also produce prints for museum exhibits and corporate photography installations. I am building a new print-making studio. I would like high CRI lighting for my print viewing/color-correcting area. I need 5000K Hi CRI (95 or higher) for color correcting as well as 2700K and 3000K high CRI to view prints for how they will look under gallery or museum lighting. I would prefer to have one light source to be able to produce all three color temperatures. Each color temperature would be used one at a time. Which of your products would work best for my application?

Our high CRI LED lighting offerings sound like a great fit for both the color viewing (D50 / 5000K) as well as gallery/museum lighting conditions (2700K/3000K).

​Unfortunately, we do not offer any products that feature the ability to switch between those color points, so we would instead recommend installing separate lamps for each of the color points needed.

​For the D50 / 5000K color point, our line of NorthLux or D50 products will work well for your needs. For example, please see below for our A19, T8 lamp or T5 fixture options:

Our 2700K and 3000K are a bit more limited in form factors. Below is our A19 and BR30 lamp option:

If you can let us know a bit more about the lighting installation in terms of fixtures and location, we'd be glad to assist with some additional recommendations and guidance!

Will your T-8 NorthLux 95 CRI LED tubes operate with a dimmable ballast allowing me to dim the output and still maintain the same color temperature and color rendering index?

Unfortunately our T8 LED lamps are not dimmable, and will not work with a dimmable ballast. Sorry for the bad news!

Will my existing fixtures work with NorthLux™ 95 CRI T8 LED Tube Lights?

I'm an artist and I need better lights for my studio. I currently have 8 fluorescent bulbs that measure 47" from end to end. The NorthLux sounds perfect but I need to know exactly what I need in order to use them. Will my existing fixtures work or will I have to replace them? 

The first thing to check is to ensure that our 4-ft T8 lamps will physically fit in your fixture. If your current lamps measure 47" (hopefully 48" if you include the pins), that sounds like we're definitely in the ballpark!

​If you can provide additional photos or model numbers of the current lamps, that should be helpful for us to confirm. A common designation, which would affirm physical fit, would be "F32T8".

We will next want to confirm electrical compatibility. Our T8 lamps can be used in fixtures without rewiring anything, if the fluorescent ballast used in the fixture is listed on our compatible ballast list. The compatible ballast list can be found in the instruction manual below:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

Should the ballast model not be listed on our compatible ballast list, the fixture will need to be rewired to bypass the ballast completely. Additional connectivity diagrams are also shown on the instruction manual posted above.

Below is the photo of what I have. I put these lights up sometime in the early 90s so everything is quite old. I see the code F40T12 which is not what you specified (F32T8) so something tells me I'm going to have to replace everything. 

The F40T12 is an older, larger lamp compared to the F32T8, but the length and pin connection are identical, so the good news is that the existing fixture will physically accommodate our T8 LED lamps.

​The (slightly) bad news is that the F40T12 fluorescent lamps use a different type of ballast technology that our lamps are not compatible with. This means that the existing fixture will need to be rewired such that the fluorescent ballast is completely removed, or bypassed.

The fixture will need to be rewired according to the diagrams shown in the installation manual, which I have linked to below:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

If you are not familiar with or are uncomfortable with rewiring your fixture, we would recommend working with an electrician to get that complete.

The fixtures I have are really old and were pretty cheap to begin with. Would it make more sense to just take them out and get new ones? If so, could you point me to ones that you would recommend? 

From a safety and performance perspective, old fixtures are generally not a problem, unless you are seeing some significant corrosion or other signs of fixture degradation.​If, however, for aesthetics or other reasons you are looking to replace the fixtures completely, that can also be an option for sure.​It can be a bit tricky to identify new compatible fixtures, however, as many are still sold with fluorescent ballasts inside, and we have no way to guarantee compatibility since fixture manufacturers will often swap out the ballast inside the fixture without advance notice.

We wish we had a list of tested fixtures, but unfortunately we do not have any at this time. A search for "LED ready T8 fixtures" online may yield some results for fixtures which specifically do not have the fluorescent ballast pre-installed. Our lamps should be fully and immediately compatible with fixtures that have this designation.

How about these? LED Ready High Bay

We've reviewed the specs for PLT-20023, and while we have not tested this product, I believe this should work well with our T8 LED lamps.​The "single ended direct-wire" and T8 4-ft length specifications are the key specs, both of which are a match with ours.​

Do you offer 8ft T8 LED Tube Bulbs with the same color of (5000K or 6500K)?

Still trying to come up with a solution for lighting this studio space. I’m afraid the LED strips are going to be problematic as installation. I think the T-8 LED bulbs might be better, and more reliable overall. My calculations to achieve 126K-plus luminous would require 60 4-ft tubes at 12 feet up. Any chance you can offer 8ft. tubes with the same color spec ( 5000K or 6500K )? Also, are standard fluorescent bi-tube or quad-tube fixtures compatible?

While we currently do not offer 8 ft T8 LED tube light products at this time, I would be more than happy to let my product team know of your interest in the form factor for future consideration.

Further, our 4 ft T8 LED tube lights will unfortunately not work within bi-tube or quad-tube fixtures. Generally speaking, unless the light fixtures are 4 ft in length, our products cannot physically fit within them.

Though we may not have the precise products that you described available.

 If we wanted to create ten rows of 6 each end to end or 3 rows of 6 pairs each, would that be feasible? 

As long as the T8 lamp fixtures can accommodate 4-ft tube lights, they can be configured in any layout, including 10 rows of 6 lamps, or 3 rows of 12 lamps.

Generally, it would help distribute the light most evenly if the lamp fixtures are placed as equally distributed as possible.

Will the PhotonTube™ T8 LED Grow Light Tube be effective for Cannabis to Grow in a Grow Tent?

Will this fixture be effective for cannabis to grow in a grow tent? PhotonTube™ T8 LED Grow Light Tube for Horticulture. What intensity would be best?

Our PhotonTubes are generally best suited for seedling growth, as it provides even and diffused soft light intensity.

​For a grow tent, we would recommend our PhotonPanel instead, for which you can find details below:

Full Spectrum LED Light for Car Repair/Restoration

30 ft. X 40 ft. with 12 ft. ceiling. All white inside. Used for car repair/restoration. Need light to reach under car lift. Did I do the calculator right? 120,000 lumens? The full spectrum is nice. 

I have attached the store links below for the products which were discussed during the call. If you could provide further details about the space, we would be more than happy to provide some more specific product recommendations as well as product quantity suggestions.

The NorthLux™ 95 CRI LED Shop Light Fixture was the primary product which was discussed. Although this item is currently back-ordered until February, this integrated fixture can be easily hung using the included chains and hooks. This product can also be daisy-chained together for easy installation.

In the event that you would prefer to use mounted ceiling fixtures which utilize tube lighting, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product.

For the installation which was described, we recommend the 5000K color temperature option. The light which would be emitted by 5000K light sources would be neutral, balanced, and very similar to natural daylight.

Difference between D50 and Centric Daylight

What is the difference between the D50 and the Centric Daylight?

While both the D50 and CENTRIC DAYLIGHT products offer a 5000K color temperature, the D50 products are calibrated to a specific ISO color point for color viewing applications. For more information, please see below:

Would your Full spectrum LED T8 Tube leads be a better choice to protect vision?

I read an article about how LED lighting is real bad for your vision. I think because of too much blue light. Would your full spectrum leads be a better choice to protect vision?

Lights which feature a low CRI, as well as a high flicker rate, can be detrimental by causing excess fatigue to our eyes.

Alternatively, products such as ours which emit light which closely resembles that of natural light, and feature a high CRI and low flicker-rate, should not cause nearly as much eye fatigue.

The blog on our website feature several in-depth posts which further explain the safety of LED lights, as well as the details regarding full spectrum lighting. I have provided several blog post links below, which might prove to be useful.

Full Spectrum Flicker-Free T8 LED Tube Light for Fluorescent Replacement

I am looking to replace our light table fluorescent tubes with your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. In this situation where one is working on top of the lights would we order the 5000 or 6500K lamps? Also, these Mainline Tables have fluorescent dimmers, would this work with your lamps? 

Without knowing more about light table usage, the color temperature selection may come down to personal preference and comfort. The 5000K color point lamps will emit more of a cool warm light, while the 6500K color point lamps will emit light similar to direct full sunlight.

Below is the related article which may help with your question.https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

However, if you find one option to be preferable over the other, simply let us know and we would be happy to issue a return label for a full refund under our 30-day return policy.

Unfortunately, our T8 LED tube light products are not compatible with dimmers, which would include the dimmer on your light table.

High CRI T8 LED Tube Lights for a Print Company

I am working for a print company and I am looking to switch out the old fluorescent T8 bulbs with LEDs. Around the press, it is important to have a light that is as close to daylight as possible so that the pressman can accurately gauge how the colors are coming out and make adjustments as needed. I am wondering what the best bulbs for this application would be. I am assuming that a bulb with a high CRI would be best but any ideas on what would work best would be appreciated. 

Our high CRI T8 LED lamps sound like a great fit for the application. You are absolutely right that high color rendering (CRI) would be very important in your installation in order to ensure that color appearances can be judged accurately against a daylight color standard.

Specifically, we find that most of our customers in printing industries strive to adhere to the ISO D50 standards, which defines a very particular color point for natural daylight calibrated to 5000K. Below is some additional information on D50 which you may find useful:

https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

​Below is our T8 LED tube light product which is calibrated to the ISO D50 standard:

These lamps will fit in standard 4-ft fluorescent fixtures, and the fixtures do not require any further modifications as long as the fluorescent ballast is listed as a compatible product here.

Will I be able to double end direct wire these bulbs. We have been replacing the old fluorescent bulbs in the building with LED and have been going the direct wire route. I would prefer to keep these the same as all the others so there is no confusion if anything has to be changed. 

The lamps are indeed compatible with double-ended direct wire configurations. Furthermore, they can be used with both shunted and non-shunted tombstones, so we should be covered with whatever wiring configuration you already have in place. (We wholeheartedly agree that maintaining consistency across all of the fixtures is a great idea from a safety and maintenance perspective!)

​I've linked to our installation manual below, which includes instructions on permissible wiring configurations:

​https://www.waveformlighting.com/datasheets/UM_4024.pdf

The ballast is quite old and is not listed on your compatible ballast list. I've attached a picture of the ballast in hopes that you could let me know if the bulbs will work with our setup. As well the fixture has safety starters for each bulb which I assume should be removed before the LEDs are put in, is that correct?

You are correct that the ballast is not listed on a compatible ballast list, and as such, unfortunately this would not be a permissible installation method and would void the warranty on the product.

You are also correct that the safety starters would need to be removed.

We completely understand the desire to go with a plug-and-play installation, and regret that we are unable to support use with the older fluorescent ballast model.

We would perhaps recommend rewiring a single fixture first to test out our lamps, and if you and your employees are happy with the light color, accuracy and brightness, proceed with the rewiring work for the remaining fixtures.

LED Lights for Windowless Office Lighting

I want to create a work environment where I do not fatigue my eyes or tire. The office is 180 sq. ft with no windows, so I want it to be brightened up. The walls are light white/greyish. Dull current fluorescent lighting has been depressing and makes me feel tired. I also only need 9 T8 48" 5000K 95 CRI tubes.

Our CENTRIC DAYLIGHT T8 LED lamps sound like a great fit for your windowless office. The 95 CRI will ensure that the light quality matches that of natural daylight, while the flicker-free light output could be a nice, added benefit if eye fatigue is a concern.

Light Fixtures for Wall Wash Lighting in Dropped Ceiling

I am designing lighting for artwork in my remodel. I have to use a dropped ceiling so I need lights that can be installed in the ceiling. I can only find light bulbs. Do you sell light fixtures to be installed in ceilings to light up artwork?

Unfortunately, we do not currently sell light fixtures which can be installed directly into ceilings.

However, we do sell T8 LED tube lights, such as the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product, which are designed to be installed within ceiling light fixtures.

T8 LED Tube Lights and Shop Light Fixture for Art Studio

I am building a brand new studio for my art practice and I have been recommended your NorthLux™ 95 CRI T8 LED Tube for Art & Studio. Please could you advise on the light fixtures I should be looking at? I see that you say any T8 fitting will work but do you have any ones you prefer that work the best with your tubes, I am looking at a suspended 4ft system that will run in a line. 

We can confirm that our T8 LED tube lights will indeed function in any fixtures which utilize the G13 Medium Bi-Pin connection style.

While we do not have any specific light fixture recommendations, we do recommend installing the T8 LED tube lights within fixtures that do not use florescent ballasts, as the ballasts may cause issues depending on the model.

In case they prove to be useful, I have provided links below for the ballast-bypass installation instructions, as well as the list of supported ballasts.

Installation instructions: https://www.waveformlighting.com/datasheets/UM_4020.pdf

Tested ballast list: https://www.waveformlighting.com/files/CD4020.txt

I want to know if your NorthLux™ 95 CRI LED Shop Light Fixture has the same light output and color as the tubes, can they be joined or held together in a line (probably 4) and can they be hardwired so I can switch all on together vs hang cords?

We can confirm that the NorthLux™ 95 CRI LED Shop Light Fixtures feature the ability to be daisy-chained together using the included cord.

However, as the product comes with a wire and plug already installed within the unit, it cannot be hardwired without modification.

T8 LED Tube Light for Bathroom Installation

Our apartment has weird florescent fixtures in the bathroom. For replacements, we were told to order Sunlite T8 High Performance Medium Bi-Pin (G13) Base Straight Tube Light Bulb, 25W/3500K which is horrible. I am considering ordering CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Light in 5000K. The fixture is for a 48 inch bulb. Will these work in a bathroom? Also, two of the fixtures are for 24 inch bulbs. Do you have the T8 in 24 inches?

Our CENTRIC DAYLIGHT lamps sound like a nice alternative for what you are looking for.​Our lamps are 48" in length and should therefore be a great fit for your bathroom fixture. The lamps are rated for damp location use and there should similarly not be any issues in terms of the installation location.​We do offer the lamp in a 4000K color temperature option as well, which may be a more optimal color temperature for a bathroom location for residential installations.

We unfortunately do not have any 24" bulbs at this time. We're sorry for the inconvenience!

Do you have a D50 5000K and 4000K in 90+ CRI?

We are interested in your D50 5000K model 4026.2F.50 light fixture, T8 tubes model 4024.50.4P, or perhaps the Flexible Strip 7101.50 mounted to the aluminum channel and quite possibly a combination of all. Key is D50 5000K 90+ CRI. Also looking for something similar in 4000K

​The ABSOLUTE SERIES is not available in 4000K, but the T8 lamps and T5 integrated fixtures are available in 4000K. The part numbers are 4024.40 and 4026.2F.40, respectively.

We are concerned about UV and IR from the above lamps. I realize output in these regions would be low, but is there a way to quantify what level is considered damaging to artwork, photographs, documents, etc.

We do not have any data on hand for this, but I would expect that this can certainly be quantified in irradiance units (e.g. mw/cm2) accompanied by a wavelength range (e.g. UV-A), or 340-400 nm). If your customer has any specific requirements in terms of irradiance, that would be very helpful for us to verify compliance; if not, a starting point may be showing them our photometric reports which show essentially no energy emission in the UV and IR regions.

T8 LED Tube Lights for Avian Applications

I see you have specific bulbs for avian applications! Is/are any of your led tube bulbs good for this application as well? I have tube style fluorescent bulbs in my bird room currently! I just want to make sure that your tube style won’t be bad for my birds?

We're happy to confirm that our T8 LED tube light products, such as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, offer extremely similar high CRI values as our avian bulbs. As such, both products feature great spectral coverage.

CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light for Paint Shop Application

We are updating the lighting in our paint shop and your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light seems like a perfect retrofit. The most important thing is that the paint colors appear inside as close to the way they appear outside. I wanted to check in and see if these are the bulbs that you would recommend, and if you would suggest 4000K, 5000k, or 6500k. Based on your write-ups the 6500k seems like the most appropriate - but I always like to check in with the pros! 

Based on the description provided, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light in the 6500K color temperature option. The light which is emitted by the 6500K tube lights will be extremely similar to that of full daylight.

That being said, please note that we offer a 30 day return policy for all orders. In the event that you decide on a different color temperature after installation, please let us know and we will gladly issue a return label.

Are NorthLux™ 95 CRI T8 LED Tube for Art & Studio Dimmable?

Are these dimmable? NORTHLUX 95 CRI T8 LED

Unfortunately, the NorthLux™ 95 CRI T8 LED products are not compatible with dimmers.

Just need to know which LED lamps you have that are dimmable and are at least 5000K

We can recommend our Full Spectrum E26 BR30 LED Bulb product, which is dimmable and available in the 5000K color temperature.

Here is the product link:https://store.waveformlighting.com/collections/br30-bulbs/products/full-spectrum-e26-br30-led-bulb?variant=29404004253798

PhotonBlast™ LED Grow Light Fixture for Horticultural Lighting Installation

It's not clear, but is this product sold as two fixtures in one or one grow light fixture? One photograph shows two light fixtures in the gallery of images (second and third from the left). In addition, the other fixture does not appear to have a chain linked to it.

We can confirm that the PhotonBlast™ LED Grow Light Fixture product is indeed sold as one lighting fixture unit, rather than two. Each shipment of this product will also include the hanging hooks.

Can you confirm if two of these fixtures will be necessary for a shelf 48 inches wide? I am wondering if one fixture is enough if I am choosing to grow orchids like Paphiopedilum and Phalaenopsis that do not need high light levels like other more sun loving genera.

The answer may depend on the ideal lumen output required for the orchids which you have mentioned. For reference, one unit of the PhotonBlast™ LED Grow Light Fixture will have a lumen output of 4200.

Generally, one of our PhotonBlast fixtures is equivalent to approximately two 4-ft T5HO lamps (54 watts).​One key difference, however, is that the PhotonBlast product features a 95 CRI, which indicates that it provides a much more complete spectrum than a traditional fluorescent T5HO lamp, and this may provide you with far better growth, even at the same brightness level.

I am still weighing what would work since you sell 4000K and 6500K. The trouble is that I do want to raise vegetable and flower seedlings later next year so I need to weigh my options.

Low-light orchids - 1200-2000 fc (12,900-21,500 lumens)

Medium-light orchids - 2000-3000 fc (21,500-32,300 lumens)

High-light orchids - 3000 fc. (32,300 lumens)

Orchid growers use a mix of two 6,500 Kelvin and 3,000 Kelvin bulbs in a 4-tube fixture and 4,000K bulbs would provide roughly the same type of light. I'm guessing that I need only one 4000 K bulb?

In almost all cases, mixing lamp colors is not an optimal situation, and is only done when a mid-point color option is not otherwise available. As such, I would not foresee any issues whatsoever with selecting a single color temperature for your installation.

The midpoint between 3000K and 6500K is approximately 4750K, so our 4000K would be a closer match for what you are looking for. In my experience, 4000K works well for microgreen seedling growth so I would imagine this would work well for orchid seedlings as well.

It's a bit difficult to comment on the footcandle and lumen values, as the two metrics refer to different things (illuminance and light output, respectively) and will depend on a variety of factors such as fixture orientation and distance from the plants. As mentioned in a prior email, we believe that each of the PhotonBlast fixtures can be thought of as a replacement for two T5HO lamps.

Your instructions for hanging the light fixtures (Photon LED) using the S chain are poorly written and unclear.

I have not been able to determine from the PR photos for the product how they were hung - the S hook is different in one picture from the other picture showing it hung from the shelving.

I've reviewed the product literature and have confirmed that the hanging hook chain used in the grow light shelving photos is indeed the same hook chain, but installed in a modified manner.​Specifically, the hook is inserted into the other end of the hanging chain in order to create a loop. This loop is then used to suspend the fixture from the wire shelf shown in the photo. Below is an annotated photo.

LED Tube Lights Fluorescent Replacement Installation

If I have Type A bulbs that are designed for use with a ballast system, will they still function correctly in a non-ballast environment? Can they be connected as if they are Type B, or will the lack of ballast create problems?

Is there an easy way to tell if the lamp is single-ended? Should I assume they are all double-ended unless otherwise marked?

We are certainly in agreement that removing the fluorescent ballast is an excellent idea, especially given the compatibility and potential safety concerns that you experienced.

By definition, UL Type A lamps will require a fluorescent ballast to operate, so once the fluorescent ballast have been removed, you will not be able to use the UL Type A lamps in those fixtures anymore.

That being said, some products, such as Waveform Lighting's T8 LED tubes, can be used in both ballast and non-ballast fixtures. In terms of the UL Type nomenclature, they are considered UL Type A+B.

If you've been able to confirm that your lamps are UL Type B (ballast-bypass), you will need to confirm with the manufacturer or product marking to see whether those lamps are designed for single-ended or double-ended installation. All single-ended installations will use non-shunted lampholders, while double-ended installations may be shunted or non-shunted.

Do you have a high CRI T8 replacement in a 2-foot length?

I see you have a T8 CRI in a 4-foot tube. I am looking for a direct replacement for 2-foot T8 Fluorescents in the Studio. We need a total of 8 lamps for now. Do you have a suitable product? 

Unfortunately, we do not sell T8 LED lamps in the 2-ft length at this time.

Recommended Fixture for CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Lights

I need a fixture that holds four CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Lights. What do you recommend? 

Our CENTRIC DAYLIGHT T8 lamps will fit into virtually all 4-ft fluorescent fixtures. Generally, they will work best without a fluorescent ballast, and as such we would recommend avoiding any fixtures that have fluorescent ballasts already installed. Since it sounds like you are looking for a new fixture to install, you may want to specifically search for four-lamp fixtures without any fluorescent ballasts pre-installed.While we do not have any specific fixture recommendations, we would recommend doing a search for "LED ready" T8 4-ft fixtures, as this will ensure that any new fixture you purchase will not contain any fluorescent ballasts, which can cause additional compatibility issues.

Is this light single or double ended?

The lamps can be used in both single and double ended fixtures.

For your reference, below is the installation guide which shows wiring and additional details for both single and double ended installations:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

Disposal of LED fixtures with integrated LED tube light

I am interested in replacing fluorescent shop light fixtures with LED fixtures. How does one dispose of the LED fixture with integrated LED tubes at the end of its use?

While the specific laws and regulations may depend on your local authorities, integrated LED fixtures are typically considered universal waste and will require a special disposal process.

Please see below for a detailed write up on this topic:

https://www.waveformlighting.com/home-residential/are-led-lamps-considered-universal-waste-how-to-dispose-of-led-lamps-properly

Here is a link to the federal regulations which have a very broad definition of "lamps":

https://www.ecfr.gov/cgi-bin/text-idx?SID=0501d91ec562faafa833c60c2404d806&mc=true&node=pt40.27.273&rgn=div5#se40.29.273_15

Are the NorthLux™ 95 CRI T8 LED Tubes dimmable?

I purchased 2 4-packs of the Northlux T8 5000k and installed them into t-8 fluorescent fixtures. We have five fixtures running next to each other in our office/photography printing space. The color is perfect! But they are too bright. We took out one bulb from each fixture but still too bright. Would these bulbs be dimmable?

Unfortunately, the NorthLux™ LED T8 products are not dimmable. That being said, we do have a few recommendations which might help.

For example, prismatic diffusers are commonly used with tube light fixtures and can assist in softening the light output.

Do the 4000K lights give the same color accuracy as the 5000K? Also, does re-wiring the fixtures (as opposed to just using the existing fluorescent ballasts) make any visible difference?

The 4000K and 5000K color temperature T8 LED lights that we offer feature the same 95 CRI. This 95 CRI allows for colors to appear vibrant and natural under both color temperature options.

Regarding re-wiring the fixtures, this typically does not make a visible difference in the perceived brightness emitted by the T8 LED bulbs.

Our electrician noticed that the new bulbs above got hot fairly quickly, which seems weird for LED bulbs. Would re-wiring the T8 fluorescent fixtures eliminate this?

Regarding the heat output, a small amount of heat generated by the lamps is normal, but if it is more than warm to the touch, this may potentially indicate a ballast compatibility issue.

We recommend either removing the ballast from the fixtures or alternatively installing the tube lights via a ballast bypass, as this will eliminate any potential compatibility issues between our lamps and the ballast. Instructions for this process can be found at the link below.

https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

Are the NorthLux™ 95 CRI T8 LED Tube and FilmGrade™ White LED Strip Lights flicker-free for shooting video?

I’m wondering if two of your products are flicker-free for shooting video:NorthLux™ 95 CRI T8 LED Tube for Art & Studio flicker-free for shooting on video? & FilmGrade™ WHITE LED Strip Lights

We can confirm that both our FilmGrade™ WHITE LED Strip Lights and the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product mentioned is flicker-free.

If a light isn’t mounted in a ballast, is there another solution in which I’d be able to operate a bank of lights of a switch in a similar way to a typical shop-light setup?

For installing our T8 LED tube lights into fixtures, such as ‘shop light’ style fixtures, we generally recommend that the fluorescent ballast is removed. Alternatively, these bulbs can be installed using the ballast-bypass method.

The instructions for both installation options can be found in the link below.

https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

Alternatively, the FilmGrade™ WHITE LED Strip Lights can also be mounted within lengths of our flat Aluminum Channel for LED Flex Strip products.

Do you have a 3K version of PN 4024? Will this go into a T12 fixture?

Do you have a 3000K version of PN 4024? Also, will this go into a T12 fixture?

Unfortunately, we do not offer the Full Spectrum T8 LED Tube products in the 3000K color temperature. However, I would be more than happy to pass along your interest in this item to our product team.

Both T8 and T12 lamps utilize the same G13 (Medium Bi-pin) base. Therefore, if the T12 fixtures you have are designed for 4-ft T12 fluorescent tubes, our T8 LED tube lights, which are also 4-ft in length, will also fit in the same fixture.

That being said, our T8 LED tube lights are only compatible with the electronic ballast models listed in the installation guide below.

If the ballast used in your fixture is not on our list, we would recommend removing or bypassing the ballast in your fixture. The same T8 LED tube lights are also compatible with ballast-bypass installations, which are illustrated on page two of the installation guide.

Do you have a high CRI 48" 5000k T8 LED tubes replacement with no PWM flicker?

I am currently looking for replacement 48" 5000k T8 LED tubes for my office. I want something with a high CRI and also no PWM flicker. I see your company has two listings. "CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light" and "NorthLux™ 95 CRI T8 LED Tube for Art & Studio" Is there a difference between the two? How "Flicker-Free" are they?

Our 5000K high CRI, flicker-free LED tube lights sound like a great fit for your office space!

As mentioned, the two products that have the same part number listing are indeed the same product. They have been listed on separate product pages for marketing purposes, and we do apologize for the confusion caused.

Our T8 lamps do not use PWM as they are not designed to be dimmable. As such, their flicker % is kept to below 2%. (All PWM dimming systems have a 100% flicker rate). In addition to photometric testing, we also periodically perform tests using a smartphone's slow motion video capture mode and can confirm that we do not observe any flashing behaviors associated with non flicker-free lamps.

Also, our test report for T8 LED tube light in 6500K shows the measured flicker values of 2% and a flicker index of 0.00. The electronics of the 5000K are the same and we would expect similar, if not identical, flicker metrics.

One additional factor to consider would be whether or not a fluorescent ballast is installed and used in the current T8 fixture. For our lamps, eliminating the fluorescent ballast can be a sure-fire way to ensure that the ballast is not introducing any extra voltage or current fluctuations that can lead to additional flicker.

Lighting up a garage with no windows

I am looking to light up a garage with no windows. It is horrendously hot here in the summer and I want to be able to work in my garage with the doors closed, with the air-conditioning on. Looking into high CRI lighting so that it is nicer in there with good quality light.

The summer heat issue is totally understandable and it sounds like high CRI lighting is definitely a great solution!

For starters, LED lights emit far less heat than fluorescent and incandescent lamps, so regardless of which LED product you ultimately install, you will certainly be helping to keep your garage cooler, and you'll also be able to double-dip on electricity savings as your air-conditioning unit will not need to work as hard.

For garage lighting installations, our 95 CRI LED shop lights have been some of the most popular. Below is an actual installation from one of our customers, courtesy of Mike Fitzpatrick from Liquid Audio.

The LED shop lights are designed to be hung using the included hanging chains, and plug into any electrical outlet, so these are a great option if you're looking for some highly focused light output without having to perform any wiring work. The daisy-chain capability of these lights may also be an added benefit.

Another option would be our 95 CRI T5 linear fixtures. These fixtures also plug into any electrical outlet and can be daisy chained, but are designed to be mounted directly using the included screw or magnet mounts. In terms of aesthetics and installation, these offer a more slim and compact footprint.

Finally, if you have existing fluorescent lamp fixtures, our 95 CRI T8 LED lamps may be the most straightforward and low-cost solution. These lamps can be used to directly replace the 4-ft fluorescent lamps currently in your fixture. You'll see approximately the same quantity of light (brightness) but you'll immediately notice the improvement in the quality of light!

This is a great option if you already have the fixtures, as you won't need to perform any extra installation or rewiring work (unless the fluorescent ballast is not compatible with our lamps), keeping both fixture and labor costs down. The added benefit is that if you already have fluorescent lamps in place, you'll have a rough idea of the light distribution and brightness so you won't need to worry as much about fixture placement and modifications.

Do your T8 LED tube lights work with electronic ballasts?

Question: Are your T8 LED lamps compatible with electronic ballasts?

Our T8 LED tube lights are compatible with the electronic ballast models listed in the installation guide below.

If the ballast used in your fixture is not on our list, we would recommend removing or bypassing the ballast in your fixture. The same T8 LED tube lights are also compatible with ballast-bypass installations, which are illustrated on page two of the installation guide.

Replacing fluorescent lighting for art studio

We have an art studio which currently uses fluorescent lighting. I'm doing research on what to replace those with. I see that you have non-flicker LED tubes that fit into fluorescent fixtures.

However if I'm understanding correctly, these will flicker if put into the old fluorescent fixture?

Not necessarily. The lamps we designed are guaranteed to be flicker-free when used in a fluorescent fixture without a fluorescent ballast. The lamps can be used with existing fluorescent ballasts, but the flicker-rate would then depend on the fluorescent ballast and therefore we would no longer be able to guarantee flicker-free operation.​

Also I'm not sure what the difference is between 4000, 5000 or 6500K? What would best match for what is currently being used?

The difference between 4000K, 5000K and 6500K refers to the color temperature. The best match would depend on what color temperature rating was used prior. Generally, 5000K and 6500K are the best options for an art studio.
