How Can We Help?

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.

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.

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. 

We have attached two product links below that we believe might be a great fit for your 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:

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. 

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:

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.

Below is an actual customer photo from one of our customers, courtesy of Jimmy Sig.

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.

Please see below for additional links that should help clarify:https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbshttps://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose
