48' x 1.5" Full Spectrum for Office Lighting

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

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

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

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

Lighting from Home Office in Room with No Windows

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

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

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

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

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

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

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

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

Human-Centric LED Lighting for Windowless Office

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

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

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

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

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

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

Light Recommendation for Office and Residential Lighting

Deciding between the 2700K or 3000K Centric Home and 4000K, 5000K, or 6500K Centric Daylight.

Do Lux24™ Circadian and A19 LED Filament Bulb fit in a regular socket at home? I have three ceiling fans/ lights that need a smaller base. Do any of these fit in the smaller base?

I need good lighting in an office, and a bathroom with a four-bulb fixture. I think I want a softer feeling for my eyes but also to see clearly. However, they can be so bright it is too bright. Not sure about the 2700K or 3000K centric home - It will be warmer, but will it be that healthy full-spectrum? Will it be bright enough to help me see everything and think?

Would the Lux24™ Circadian LED Bulb - 2400K works in an office? 

My bedroom has those Full-spectrum solutions/ blue Max brand candelabra lights in the ceiling fan. Most nights I avoid even turning on the light in the bedroom as I get into bed- because they are so bright. I do not have a bedside lamp. If those bulbs would fit in the ceiling fan- that takes the smaller bulbs, I would- but these don't fit into the smaller base - right?

The A19 bulbs referenced utilize the standard E26 base, which is a very common standard for home fixtures, such as lamps and recessed lighting.

The base that you are likely referring to is known as an ‘E12 candelabra base’, which we currently do not have available in our catalog. 

For offices, we recommend the 4000K color temperature. You might specifically be interested in the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb for your work area. This color temperature is cooler than the warmer 2700K options, though they will both offer full spectrum output. 

For bathroom fixtures, we would likely recommend the 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which is designed to be suitable for damp locations and can offer full-spectrum light output. 

As previously noted, the 4000K color temperature is the most common option for offices and workspaces. The 2400K is more commonly used for evening light, rather than productivity due to the very ‘warm color' output. As such, we would likely recommend the aforementioned 4000K CENTRIC DAYLIGHT™ A19 lightbulb. 

We can confirm that the 2400K Lux24 A19 lights would not be compatible with the E12 candelabra base fixture. 

Full Spectrum LED Lights for Home Office

I know about how lighting affects our circadian rhythm and how important the right light at the right time is important for our physical and Mental Health. 

Do you sell suitable ones for the UK? I would like to start with 3 light sources in the office. Then if that works well, move on to the rest of the house.

The ceiling light in the office is an LED light, so I will need to replace that with a suitable fitting, can you suggest anything? I also have a Lamp with 2 lights on it, so I can shine it in different directions.

Would you be able to suggest the best fittings to use and the Bulbs? I want the 6500k bulbs or higher if they do that.

While there are voltage standard differences between the United States and the United Kingdom, we are happy to confirm that many of our products are designed for global compatibility. 

Further, these products are available with an E27 version, as is the name for the lightbulb base that is most common in Europe. In North America, the standard E26 base has slightly different measurements and is not compatible with E27 fixtures. 

For example, we would likely recommend our 3000K E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulb as a replacement for the lightbulb within the photo provided that reads ‘A65-2D 15’ at the top of the label, as 3000K is the most commonly recommended option for offices. As you will note, this label also lists the base size of ‘E27’, as was referenced above. 

For a 6500K alternative option, you may be interested in the 6500K E27 CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb, which is also compatible with UK voltage standards. This 6500K color temperature is most common for art production and photography. 

It appears that the desk light uses both an A19 bulb, as well as a smaller E14 bulb. We, unfortunately, do not have lightbulbs available in the E14 size, though we hope to offer them sometime in the future. 

Based on our review of the ceiling fixture, it appears to be fully enclosed. As our lightbulbs require a moderate amount of airflow for heat dissipation, they would unfortunately not be compatible with this fixture. We do sincerely apologize for any inconvenience this incompatibility may cause. 

As the above products are designed for line voltage, they are not compatible with battery operation. Regarding solar power, we would recommend reaching out to a local solar expert for advice regarding your available options. 

Full Spectrum 2x4 Office Lighting for Drop Ceiling

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

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

Lighting Recommendation for my Art Home Studio Office

I'm a textile surface pattern designer and fashion designer. I work from home at my home studio office and I am in major need of new lighting. I am in a condo currently and the ceilings are about 11ft high where my lighting will need to be placed. I would like the 5000k lighting with high CRI for color matching/Pantone and painting. The only issue is I am new to figuring out what to buy. I would ideally like to buy a long 6-8ft track lighting to place on the ceiling of my studio. I want track lighting because I still want the lighting fixture to at least look nice since it is a residential condo. 

Our high CRI bulbs at 5000K sound like a great fit for your home studio office, especially for textile color reproduction accuracy.

Unfortunately, we don't have any products that would work with track lighting fixtures. we completely understand the reason for this request for aesthetic purposes, and apologize for the inconvenience! I will definitely let our product development team know of your interest.

​Currently, the closest option for a residential installation would be our BR30 lamps, which fit into standard ceiling can fixtures. Please see below for the product link:

We also offer some T5 linear lights which can be mounted onto various surfaces. This product does not require any other fixtures in our housings and can be plugged into a wall outlet directly. Below is the product link:

Natural LED light for Light Hyper-sensitivity

I have neurological vision damage and hyper-sensitivity to light or photophobia. The best light for me is a mix of natural light and a little fluorescent. I was wondering if you could recommend one of your bulb types for this type of condition.

For the reduction of eye strain, we usually recommend our flicker-free, high CRI products, such as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb. This product is also available in the 4000K color temperature, which is often recommended for office use. 

D50 vs Centric Daylight for Basement Home Office Lighting

Your company appears to be one of the best for high CRI lightbulbs. I am working on a basement-level home office with no natural light. I will be working out of this office most of the time (40+ hours a week). Your D50 5000k bulb initially caught my attention for the high CRI and R9>80. Your Centric Daylight 4000k bulbs are also appealing for a touch warmer tint. Does the Centric Daylight have a lower R9? What would you recommend for a home office? 

Generally speaking, we like to recommend the 4000K color temperature for offices and workspaces. Further, we can confirm that the 4000K Centric Daylight A19 bulb offers an R9 value of 95, whereas the D50 A19 bulb offers an R9 value of 92. 

As such, we would likely recommend the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb for your basement office. For greater output per bulb (800 vs 1600 lumens), you might also be interested in our newly launched 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulbs. 

Fluorescent Replacement for Office Space Lighting

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

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

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

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

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

Centric Daylight vs NorthLux for Home Office

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

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

​Please see below for additional information:

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

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

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

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

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

LED Strip Configurations for Office Lighting

I want to light my office with this LED strip: 


Is it possible to connect more than one strip to this power supply? 

FilmGrade™ DC Power Supply

The office is 8' x 8' and I want to build a soffit near the ceiling. I intend to line the inside of the soffit with these strips with the lights facing out into the room. I need 2x 16' strips to make it around the room. I want to use the film-grade dimmer (I have one). 

We typically recommend utilizing one power supply per 16.4 ft (5 meters) reel of LED strip light products, as the power supplies would not be able to afford sufficient power for more than one reel.

As a further consideration, the LED strip lights have a maximum combined length (defined by the hardware) of 16.4 feet. As such, powering additional lengths can lead to performance issues.

Due to this, your installation might benefit from using a second dimmer, or alternatively utilizing a single in-wall dimmer and in-wall power supplies such as the TRIAC Dimmable Power Supply for LED Strip.

We have attached a link to a layout diagram below, which we hope proves to be helpful for your installation planning. This page also contains installation suggestions and links to the recommended accessories.

LayoutMaps™ - LED Strip Light Layout 3002_3D:

LayoutMaps™ - LED Strip Light Layout 3002_3E:

So, each 16' strip would require one in-wall power supply and an in-wall dimmer?

So my setup would look like this:

(2) 16' LED strip

(2) In-wall power supply

(1) In-wall dimmer

Can you recommend a good dimmer? Will the dimming be as good and variable as the 'film-grade dimmer?

We can confirm that each reel would require a dedicated power supply. I can further confirm that the TRIAC dimmable power supply is compatible with forward-phase, ELV/reverse-phase, and MLV dimmers. 

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

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

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

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

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

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

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

T8 LED Tube Light Installation Guide: 

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

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

Flicker-free T8 LED Tubes for Vision Therapy Office Lighting

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

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

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

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

Tested Ballast List:

Product Specification Sheet:

How much LED Lights are needed for Office Lighting

I have a 12x12 home office. I’m wanting to run your LED lights (power supply, connectors) around the perimeter of the office, but I’m unsure of how many complete systems (LED lights, power supplies, connectors, etc) I need to order. From what I see the strips come in 16’ sections, and if I need to go around the entire perimeter I’d need 3, of your complete systems, but I need to how bright the three systems would be would it be better to split one or two up? The LED lights need to be dimmable. 

I've plugged the 12 x 12 foot dimensions into our lumen estimation calculator (, which suggests a total brightness of 5850 lumens for an office space (approximately 40 footcandles).

​Our LED strip lights emit 450 lumens per foot, so 14 feet would be sufficient (just short of 1 reel) to meet this brightness level.

If you plan on installing a dimmer, however, there is no such thing as being "too bright" since this can always be dialed down if needed, and having the LED strip lights installed along the entire perimeter of your office space on each side might be a nice way to provide even and well distributed lighting.

One more thing, just so I understand what I need to do to get this operational, could you please provide me with a simple diagram from power in to the LED the entire diagram of this project. Would you suggest breaking the 16' strip into 4 equal parts or even 8 equal parts and place around the perimeter. Also, can you tell me how soon you can ship once we know exactly what is needed?

Below is a simplified wiring diagram showing two 16-ft reel circuits connected to a single dimmer. In your setup, you will want to replicate this a third time for the third circuit.


​I would recommend installing the LED strips as three equal parts at 16 ft each. The reason is that if we do four equal parts (or more), that would potentially require installing four separate power supplies (or more) as each power supply is limited to powering a maximum of 16.4 ft for any given connection.

​Given the dimensions of your space, turning the corners at each 12 ft mark may be a bit of a challenge depending on the configuration of your interior. An additional diagram link below shows how the LED strip sections can be cut into shorter segments and rejoined using our various accessory items. I suspect that PN 3071 may be helpful for you when turning the corners of space.


​Below is an preliminary shopping cart I've put together for you which includes the three sets of LED strip reels and corresponding power supplies. I've also included a 10-pack of the aforementioned PN 3071 accessory.

​Our order turnaround time is typically 1-2 business days, and we do offer complimentary standard shipping which is typically delivered within a 5-10 business day timeframe. We also offer expedited shipping options for an additional charge; expedited shipping times and costs are calculated at checkout, but I would be more than happy to assist in calculating those for you if you can confirm your shipping address and cart contents.

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:

Brighter and Bluer Light for Home Office Lighting

I'm working out of my home office, I would guess the brighter and bluer I can get my room the more productive and alert I will be, no? I filled in the blanks in your lumen estimation calculator and it recommended a color temp of 3249k to 5585k. 

You are correct that increasing the blue content of a light source will generally provide increased alertness, and that 6500K would be the best color temperature option to achieve this.

​I've taken a look at the lumen estimation calculator, and it does appear that the recommended range of color temperatures would be between 3249K and 5585K if you were to stay at a lower brightness level (it looks like you entered 41 footcandles as your brightness needs).

If you did want to go with 6500K and create a comfortable space, we would recommend increasing the brightness levels to at least 50 footcandles.

The reason for this recommendation is due to the relationship between brightness and color temperature, for which we recommend ensuring that the space is optimized for. Below is an article that explores this concept in a bit more depth:

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.

LED Home Office Lighting: Best Color Temperature that Mimic Sunlight

I am trying to mimic "sunlight" in my small home office now that the days are getting shorter. The closest thing to my desired lighting that I have experienced is dental overhead lights. I recently purchased a FilmGrade A19 LED bulb, but it felt a bit cool to me. I realize that natural daylight sits in the 5600K to 6500K color range. 

1) Do you have suggestions for which of your A19 or BR30 bulbs may best fit my use case? 

2) Am I always going to find "natural daylight" options a bit too cool? Would 4000K or 5000K offer a better experience? 

Getting the correct color temperature is indeed a challenge!

​You are correct that the 5000K to 6500K range is generally considered a good match for natural daylight. 4000K is also a nice option, and you may find some useful information on our blog post here.

​One thing to keep in mind that oftentimes, natural daylight color temperatures can appear a bit blue or stark when you do not have enough brightness overall. To that end, if you have any information on the total square footage being illuminated, we may be able to provide some additional recommendations on the quantity of lamps needed to provide sufficient brightness at that color temperature.

We would perhaps recommend taking advantage of our free returns policy to test and compare the various color temperature options and lamp quantities. Once you've made your mind, just let us know and we'd be glad to pay for return shipping and refund you for any returned items. 

RGB Accent Lighting with Crown Molding for Office Lighting

I'm looking to add RGB accent LED strip lighting to about 54 ft around three walls for my office room that is 22x10. I have purchased some crown molding (Orac Decor CX190). What would you recommend? I would think I can do two separate runs from the unlit 10ft wall to help cover the existing 54 feet. But I see most strands come in 16ft lengths. 

Unfortunately, we do not offer full RGB product solutions at this time. As such, you will likely need to work with third-party suppliers to purchase a dimmer, controller and power systems.​We do offer full solutions for white LED strip lights (static color). If there is any interest here, we would be more than happy to provide product and solution recommendations.

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.

Work light for textiles application used to view texture and detail, neutral to daylight color, and good for indoor use and in a desk lamp.

Can you recommend a work light that will be good for indoor use and in a desk lamp, preferably from neutral to daylight color? I am working with textiles, so not only is color important but being able to view texture and detail.

Is there a bulb you think would work? Or is there a range in color/wattage/bulb type coated or clear that I might have success with?

We would recommend our 5000K or 6500K NorthLux 95 CRI E26 A19 LED Bulb for Art & Studio products could be great options for your desk light, so long as your light fixture can accept A19 bulbs with the E26 base.

The 5000K color temperature would be closer to the 4000K mentioned, while offering a neutral daylight color point. Alternatively, the 6500K color temperature has a light output that is similar to full daylight.

Color matching for dental office lighting

I run a dental practice and am looking for better lighting in my office. I need to be able to match tooth colors with various shades of filling material (e.g. ceramic / composite resin). The industry recommendation is to use natural daylight / sunlight as the standard. I currently have 4-ft fluorescent T8 fixtures in my office. What LED tube product would you recommend?

We can completely understand why being able to properly match tooth color to filling materials would be crucial for your practice. With your existing fluorescent lighting, there's a good chance that what appears to be a color match in the office may not actually be a match under natural lighting!

From a technical specifications perspective, we would recommend 5000K with a high CRI, as this will allow you to match natural daylight / sunlight the best.

5000K is likely the most ideal color temperature for your application, as it offers a more neutral color point compared to 4000K (morning sunshine) and 6500K (blue sky). Perhaps most importantly, the high CRI value will ensure that the tooth and filling colors you see in the office are the same colors you will see under natural lighting conditions.

Please see below for our 5000K / 95 CRI product link:

These LED tube lights include DirectWire™ technology, so you'll be able to re-lamp your existing fluorescent fixture without having to worry about re-wiring or re-configuring the ballast connection. Simply remove the fluorescent lamps, and install our LED tubes and you'll be up and running!

Finally, we offer a 30-day free returns policy on our products, so if you're unsure, we recommend testing the lamps to see how they work out for you. If they aren't what you're looking for, we will gladly pay for return shipping and provide a full refund.

LED lights to replicate natural daylight in office space

I would like to upgrade the lighting in my office space. My goal is to get lighting that's closer to natural daylight, and am hopeful that I can create a healthier lighting environment for myself and my colleagues. What lights should I get?

It sounds like the first question we would like to determine is which color temperature would work best for your needs. Since you mention a desire to get closer to natural daylight, my first suggestion would be to consider 6500K.

Keep in mind, however, that 6500K isn't for everyone. It's commonly used to truly replicate blue daylight, and is popular among our customers who use the lights for graphic arts and other applications that require a true match to natural daylight at a technical level.

In reality, most office spaces will utilize a "warmer" 4000K or 5000K color option. These colors would be closer to natural sunlight, rather than daylight, and might be a better fit, depending on your personal preferences. Here is an article comparing 5000K to 6500K that you may find helpful.

We would not recommend anything below 4000K for an office space, as these color temperatures will provide a much warmer, relaxing atmosphere that is more appropriate for a residential area.

With all color temperature options, we suggest a high CRI value of 95 or higher. A high CRI rating ensures that the spectral content, and not just the appearance, of the light source also matches natural daylight or sunlight.

Hard-wiring LED T5 linear fixtures

I'm looking to install your LED T5 linear fixtures to replace some fluorescent lamps in my office. I plan on removing the fluorescent lamps as well as the ballast. Would it be possible to hardwire this product into my fluorescent fixture?

While the product does not include any hard-wiring components and instead includes a regular two-prong plug wire, if you are able to modify the wire connection, the lamps can be connected directly to line voltage wires in a fluorescent fixture without any issues from an electrical standpoint.

You will, of course, need to ensure that the fluorescent ballast is removed or bypassed as the LED T5 linear fixtures are not compatible with any fluorescent ballasts.

For any electrical code compliance questions, we would recommend consulting an electrician for further assistance or recommendations.
