What does considered to be enclosed fixture?
Some of your bulbs say " not for enclosed fixtures". What does this mean exactly? One of mine is in a ceiling fan light with a cover. Is that considered enclosed?
As long as the lamps are not completely sealed off from air flow, the fixture would not be considered enclosed. Please see below for additional information:
Flicker-free Recessed Bulbs for Enclosed Fixtures
Do you have any nonflicker bulbs that work in an enclosed fixture?
Unfortunately, we do not currently offer standard lightbulbs that are compatible with enclosed fixtures while also providing flicker-free output.
Do need to order about 40 bulbs for recessed lights? Is either of these no flicker?
For recessed lighting, we would likely recommend our BR30 bulbs such as the Ultra High 95 CRI E26 BR30 LED Bulbs for Home & Residential and the Full Spectrum E26 BR30 LED Bulbs. As previously noted, these bulbs are unfortunately not compatible with fully enclosed fixtures.
Our BR30 lamps have a flicker rate of approximately 6%. While this is not the same level as our flicker-free lamps which have a flicker rate of < 1%, these lamps are still below the 15-30% flicker rate that is commonly seen with incandescent lamps.
LED Lights for Recessed and Enclosed Fixtures
I have a few fixtures - recessed and enclosed wall lights that need bulbs. Can someone please call me to discuss the options and pros/cons of your models?
While the majority of our products are unfortunately incompatible with fully enclosed fixtures, you may alternatively be interested in our 2700K and 3000K Ultra High 95 CRI A19 5W LED Filament Bulbs. These products are compatible with both enclosed fixtures as well as damp installation areas such as powder rooms.
What about your BR30? Can I use this in a recessed can? How does the flicker rate of the BR30 compare to your centric models? For the A21, I read it’s not dimmable. If the switch has a dimmer, can I try it in the fixture or not at all? Wasn’t sure if it wouldn’t dim or if would damage the bulb.
While our BR30 lights are available and commonly used for recessed lighting, these lights are unfortunately incompatible with fully enclosed light fixtures. As such, they may not be the right match for your installation.
So long as the dimming function is not utilized, and so long as the output is set to 100%, we would not expect the A21 bulbs to encounter issues while operating within a fixture containing a dimmer. That being said, please note that activating the dimmer during operation would likely cause damage to the bulbs.
Can you recommend a light fixture for your A19 bulbs?
I just purchased a 6-pack of the bulbs below for my home office. I'm hoping to achieve that natural sunlight feel. Can you recommend either a floor lamp or overhead light fixture that works well with these bulbs?
While we unfortunately don't have any specific fixtures that we could recommend, it might be helpful to know that these items have slightly larger dimensions than standard A19 bulbs, and may not fit into all fixtures.
That being said, we can confirm that the A21 bulbs use the same E26 base as standard North American A19 bulbs, and are not expected to have compatibility issues with the standard socket.
We have attached a link to the product specification sheet below which features the measurements of the item, in the hopes that it is useful for your purchase planning process.
A21 15W LED Bulb - Specification Sheet
Do you have high CRI recessed lighting options?
Do you have any recessed lighting options? I currently have CFL recessed lighting. I would like to replace all with LED High CRI recessed lighting. Do you sell the LED retrokit that your LED bulb would fit in?
We can confirm that our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential and other B30 bulbs are available in our catalog and are designed for canned recessed lighting fixtures.
While we do not currently have other recessed lighting options available, we would be more than happy to share your interest in that format with our product team for future development.
We are also happy to confirm that our BR30 bulbs would not require any special fixtures or adapters for use with the standard E26 base used in most residential lighting fixtures.
In the event that you would like to try these items, please feel free to take advantage of our 30-day return policy. We will gladly provide you with a prepaid return label for any unneeded items from domestic orders.
LED Bulb for 6" Can with Wide Spread 40 Degree
I am working on a home remodel. I intend to install 6" round recessed can lights. I have been told by my electric supplier that the halogen bulbs I previously used in these fixtures have been discontinued and that I have to use LED bulbs.
We want to completely avoid EMF's, do you have any recommendation for bulbs? We do not need the bulbs to change on the color spectrum, would stay around 3000K.
This is the bulb I would have used if it was still available:
Philips 53W 120V Long Neck PAR30 Halogen Wide Flood
Based on the details provided, we would likely recommend our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential. We can confirm that these lightbulbs do not create any dirty electricity as rated by FCC standards for EMF emissions.
Is there an option for 4" cans? Also can I use these bulbs in any can light or do they require specific LED components.
I want to confirm the 6" bulbs you recommend do not put out electronic, magenetic or other types of radiation.
Our BR30 LED bulbs have a width of 3.75" at the widest point, and are expected to be compatible with 4" canned lighting sockets. These lights should work optimally in the standard E26 socket, and we would not expect any functionality issues or required adjustments.
We can also confirm that these lightbulbs do not create any dirty electricity as rated by FCC standards for EMF emissions.
What's the difference between the two full-spectrum avian bulbs you carry?
What is the difference between the two full-spectrum avian bulbs you carry? What fixtures do I use with them? Prefer a bendable floor lamp.
We can confirm that while the Avian A19 bulb offers flicker-free output, the Avian BR30 bulb is dimmable.
Beyond this difference, the BR30 bulbs are most commonly used in canned or recessed lighting fixtures that have a narrower beam angle than standard A19 bulbs. Further, both will utilize the same standard socket and will offer full spectrum output with a high CRI of 95+.
While we do not sell fixtures for standard lights, we can confirm that our A19 and BR30 bulbs will fit within the standard E26 base. It might be helpful to know that this E26 base is used in most common light fixtures such as lamps and floor lighting.
Are the BR30 bulbs suitable for enclosed fixtures?
Is the Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential suitable for totally enclosed fixtures?
As our BR30 LED bulbs require a moderate amount of airflow to diffuse the heat generated during operation, they are unfortunately not compatible with totally enclosed light fixtures. We do sincerely apologize for any impact this may have on your purchase planning.
Would the LED strips be installed in place of the current T8 fixtures?
NorthLux™ 95 CRI T8 LED Tube for Art & Studio 4024.50.4P. Is this lamp dimmable?
Unfortunately, none of our T8 LED Tube Light products are dimmable. For installations where dimming is helpful, we typically recommend our LED Strip Lights as alternative light sources.
How are they installed? In the diagram attachment, we are needing a high CRI above the conference table for viewing new products and comparing the color of shipments to the original color. Would the LED strips be installed in place of the current fixtures?
We can confirm that our LED Strip Lights can be used for both commercial and residential installations. Installations commonly utilize runs of the LED Strip Lights installed within the aluminum channels, which are controlled using smart home systems or wall dimmers and powered with supplies such as the 12V TRIAC Dimmable Power Supply.
For installations where color accuracy is important, we would likely recommend our D50 or D65 ABSOLUTE SERIES™ LED Flexible Strips, which can output light that is virtually indistinguishable from sunlight.
If the lights are to be installed within a retrofitted T8 fixture, our primary recommendation would be to ensure that the power supply can comfortably fit within or around the fixture. Some customers choose to utilize the cavity where the ballasts were previously held for such installation.
Can you give me a drawing of what you speak? Can’t visualize it
Though we, unfortunately, do not have precise installation schematics on file that we could provide, we have shared a few LayoutMap links below that illustrate installations using connected segments of our LED Strip Lights powered by the TRIAC Dimmable Power Supply. We do hope that these resources prove helpful for your installation planning.
The CENTRIC HOME/DAYLIGHT LED Strip Lights featured within the below links are very similar to the ABSOLUTE SERIES™ LED Flexible Strip, though the latter has barrel jack adapters on the reel ends for power connection. As such, we would recommend using the Female DC Barrel Jack Plug Adapter to connect the wiring without requiring soldering. Doing so also makes future adjustments and troubleshooting easier, as the Flex Strip can be detached.

Which of your LED bulbs is to be used in an enclosed lamp in a kitchen area?
I see you can’t use some of these in enclosed lamps, so which can you use in an enclosed lamp in a kitchen area? That would give you enough light. Also which In an enclosed lamp in a hallway?
For enclosed residential fixtures, we often recommend the 2700K or 3000K options of the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential.
These lightbulbs offer high CRI full-spectrum output and are suitable for enclosed fixtures and damp installation areas such as powder rooms and restrooms.
Compatible Light Fixtures for A19 LED Bulbs
I have just bought 2 bulbs: NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio. I want to install them to a ceiling fixture but not lose the CRI and 6500K. Do you have a list of suitable fixtures? Or any tips for how to choose fixtures to get the best out of the bulbs I've just purchased?
These lightbulbs utilize the E26 base, which is the common standard socket for lightbulb fixtures in North America.
So long as the fixture is connected to an E26 base fixture and utilizes standard North American line voltage, the product should provide the optimal output of CRI as well as an accurate color temperature.
That being said, please note that these LED lightbulbs require a moderate amount of airflow for heat dissipation. As such, we recommend utilizing a light fixture that is not entirely enclosed, so that the heat generated during operation can dissipate.
Do these lights still work optimally from INSIDE a light fixture?
For example this kind: Progress Lighting P3925-09 Close-to-Ceiling, Nickel https://amazon.com/dp/B004K5CLBW/
I hear you about ventilation - this may not be ideal for that. But what about the white translucent covering and how much of the light from the bulbs it will impact?
What kind of light fixture will allow the bulbs to give optimal light while not shining in the eyes? I want to install them on my ceiling fixture.
As our standard A19 lightbulbs are not designed for enclosed fixtures, we would not recommend pairing them with the Progress Lighting P3925-09 fixture. Further, we do not have any specific fixture manufacturers or models that we could recommend, and we do sincerely apologize for any impact this may have on your purchasing process.
Unfortunately, we do not have any information regarding the transmission levels of the materials used in the referenced fixture. For accurate transmission data, we recommend reaching out to the hardware manufacturer directly as they likely have information available regarding the average transmission levels of light sources placed within them.
As a baseline for comparison, it might be helpful to know that the clear polycarbonate material used in our LED Shop Light Fixtures is fully transparent, yet reduces the overall transmission of the light source by roughly ~10%. As such, we would suspect that an opaque enclosure would block the transmission even further.
As an alternative option to our standard A19 bulbs, we would likely recommend our 2700K or 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which are suitable for enclosed fixtures as well as damp installation areas such as bathrooms.
What does a 6% flicker rate mean?
I have a 4 lights rail fixture, currently running on 75W E27 BR reflectors. I'm looking for a flicker-free alternative. If I got it right, E26 bulbs should work, though not a perfect fit. As far as I understand, your only option is the 6% flicker bulb. What does 6% mean? that when it "flickers", it is only 6% less than full power? How is it in comparison to indecent flicker?
While the measurements between the E26 and E27 are very similar, we find that the two standards are not always compatible. We have attached a link to a blog post on the topic below, in the hopes that it proves to be helpful for your purchase planning process.
E26 vs E27 Bulbs - Interchangeable? Not Necessarily!
Generally speaking, a 6% flicker rate means that there will be a 6% relative difference in brightness between the maximum and minimum brightness output by the light source during a flicker cycle. The lower the relative difference, the less noticeable flicker usually is.
Compared to our flicker-free LED lights (such as the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb) which offer a 0% flicker rate, traditional incandescent light sources typically have a flicker rate of 15%.
I know your article about e26/e27, but I still don't understand what might happen. On this page, you wrote that you "recommend exercising caution if used with E27 fixtures." Does it mean that if the bulb work during the day, and not 24/7, it should be fine? And when will you have E27 versions of these?
When E26 and E27 bulbs and fixtures are used interchangeably, the measurement differences in the base may cause arcing to occur at the gap between the electrical connection points. This arcing may cause hazardous electrical hazards to occur, which may damage the products and void the warranty. This is the primary reason why we recommend selecting a bulb that matches the socket used by the fixture.
Can I use your lightbulbs in any light fixture that has a glass cover?
CENTRIC HOME™ Flicker-Free A19 10W LED: I want to use your bulbs in my ceiling-mounted light fixtures. They all have glass covers and are what I would consider being "enclosed", but I don't understand why your bulbs would not work in them. Am I misunderstanding your use of "enclosed" or can I really not use your lightbulbs in any light fixture that has a glass cover?
As our standard A19 LED lightbulbs contain hardware and circuitry that traditional incandescent fixtures do not, there are heat dissipation requirements that we consider during operation. If the internal components are unable to disperse heat when installed within a fully enclosed fixture, the heat will eventually build up within the product and cause performance issues.
As such, we recommend that they are used exclusively in fixtures that have at least a moderate amount of airflow, such as open-ended wall sconces or traditional open lamp fixtures.
As an alternative, you may also be interested in our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which are suitable for damp locations while offering the same high CRI of 95+ as our standard bulbs.
Will the Seagull Lighting Fixture work for the Centric Daylight T8 LED tube?
I want to change my fluorescent bulbs to LEDs. Currently, I have:
Seagull Lighting Fixture/Model 59132LE-15/120V 60hz, 64W, 0.8Amps. Use F32T8 Replacement lamps only, E192796 Suitable for damp locations/Bulb Type: 2 medium bi-pin T-8 32w/Ballast: 120v Electronic NPF ENERGY STAR Qualified Offers energy-saving fluorescent lighting.
Will they work for the Centric Daylight one, or is it different from that one? If the other instructions will NOT work, do you have instructions for the Centric one?
Based on my review of the details provided, it unfortunately does not appear that the ballast within the fixture is compatible with out T8 LED Tube Lights. If you have a specific model number for the ballast, please let us know and we would be happy to check it against the list.
That being said, we are happy to confirm that the ballast bypass instructions for direct wiring the T8 LED Tube Lights are identical across both the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light and the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. As such, please feel free to utilize the user manual featured for either product.
Avian Full Spectrum E26 BR30 LED Bulb for Birds
Do these work in a recessed lighting fixture?
We can confirm that our BR30 lightbulbs are rated for recessed lighting fixtures.
I have an aviary with 3 recessed cans in the ceiling. Would 3 of these bulbs create too much light? These fixtures are currently on a dimmable timer.
As a starting point, it might be helpful to compare the lumen output of our lights against the output of the lightbulbs currently installed in the recessed ceiling fixtures.
As each of our Avian Full Spectrum E26 BR30 LED Bulb for Birds provide 800 lumens (60W equivalent), three units would provide a total of 2400 lumens. So long as this lumen output does not greatly exceed the lights currently installed, we would not expect there to be issued with glare or over-illumination.
You may also be interested in trying our Lumen Estimation Calculator, which provides a lumen target based on the dimensions of an installation area. This tool will also provide recommendations for item quantities to meet the lumen targets, as well.
Do you have fixtures that work with your PhotonTube™ T5HO LED Grow Light?
Do you sell fixtures that will work with your PhotonTube™ T5HO LED Grow Light Tube for Horticulture? I'd like to purchase either two-tube or four-tube fixtures that will work with your bulbs when I purchase them.
Unfortunately, we do not currently have any fixtures that are designed to house the PhotonTube™ T5HO LED Grow Light Tubes for Horticulture. We would like to sincerely apologize for any impact this might have on your purchasing process.
That being said, based on my review there appear to be several T5HO fixtures options available from other online retailers such as Amazon and Home Depot.
I have several LED T5 fixtures that have L and N labeled at one end and NOP at the opposite end. I’m guessing that the L/N end is for Line and Neutral and the other end is for No Power. Will your PhotonTube Grow Light Tubes work in this kind of fixture?
Based on the details provided, it does appear that the fixture would be compatible with our T5HO lights.
As a further note, we would also recommend checking the fixture ballasts to ensure compatibility. If they are not compatible, the T5HO lights can be made compatible by rewiring the fixture to bypass the ballast.
PAR30 Bulbs for Residential and Photo Lighting
I have (6) 5" halo lights in my kitchen that I'd like to get some PAR30 bulbs for but I'm having trouble deciding on the best color temperature for the space. I'm concerned that 3000K will be too warm and wanted to get your recommendation. I'd really like to talk to someone about options because I have several different projects I'm working on beyond the kitchen and want to see what our options are.
While we do not have PAR30 products available, it might be helpful to know that we offer the 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential, which utilizes the same base and input voltage as PAR30 lights.
If you would like to try our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential in your kitchen, please note that we have a 30-day return policy. If any items from your orders wind up being unneeded, let us know and we will gladly provide you with a prepaid return label.
Can full spectrum bulbs be used in standard lamps?
Can these bulbs be used in standard lamps? Are special fixtures necessary?
Generally speaking, special fixtures are not necessary for use with our Full Spectrum lightbulb products.
That being said, we can confirm that our Full Spectrum A19 and BR30 bulbs will require non-enclosed fixtures so that a moderate amount of airflow can assist with heat dissipation. So long as the fixture is partially exposed, the lightbulbs should be able to operate properly.
Do you have a high CRI E26 base LED bulb for a three-way lamp?
Do you have a high CRI LED bulb with an E26 base that will work and not flicker in a three-way lamp? Preference would be for around 3000K and 450 lumens.
While we have not performed internal testing using our products with three-stage fixtures, some of our customers have let us know that our A19 bulbs function as expected when used within such products.
While our standard A19 bulbs have an output of 800 lumens, you may alternatively be interested in our 450-lumen Lux24™ Circadian LED Bulb. We have anecdotally found that this low-output lightbulb compliments residential installations quite nicely, though the output is not flicker-free.
For another alternative that is flicker-free, we would recommend our 600-lumen SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb.
If you would like to directly compare these options, please feel free to take advantage of our 30-day return policy, where we will provide prepaid return labels for any unneeded items.
Do you sell any fixtures suitable for residential or commercial light use?
Do you sell any fixtures suitable for residential or light commercial use (not troffer lights)? Or do we need to roll our own with the LED strips? Also, are your LED strips and/or your 4' LED tubes available for purchase in California? Are the restrictions just on the A19 bulbs, or is it on everything?
While we unfortunately do not sell integrated residential fixtures at the moment. We apologize!
Further, we can confirm that our T8 LED Tube Lights and LED Strip Lights are eligible for shipping to California. The newest versions of our A19 lights have been updated to be compliant with the California energy requirements, as well. As such, please feel to place an order containing those items at any time.
That being said, our new line of A21 bulbs, which feature doubled lumen output and slightly larger size, and currently not eligible for California shipping.
My primary motivation in using your bulbs would be to keep my circadian rhythm in sync and ward off the seasonal affective disorder. I was wondering whether or not color temperature is a consideration in that context. I realize that 3000K is a more common residential color temperature, but I'm wondering if - for maximum "daylight" benefits - I should be looking at a 4000K or higher color temperature? Would the higher color temperatures, which more closely match daylight, be a better choice for my application?
Generally speaking, we find that the quality of the light tends to make more of an impact than the color temperature. That being said, installation areas requiring maximum visibility do benefit from the cooler color temperatures from 4000K-6500K.
Based on the details provided, we might recommend trying the 4000K option and taking advantage of our 30-day return policy if they are not the right fit. Simply let us know, and we will gladly provide you with a prepaid return label for any unneeded items.
Bulb Recommendation for Traditional Track Lighting
I'm thinking a more traditional track lighting setup (ie, aluminum track, individual heads) might be a better solution than the LED strip due to the configuration of the ceiling in the space. Specifically, there is a beam that runs the length of the ceiling (serves as an engine hoist). To properly light the space. I fully anticipate the need for a track on either side of the beam.
Depending on your thoughts, perhaps I should more thoroughly explore your A19 bulb options for a solution. I have just about zero experience with track lighting, so would need to know how many heads, the interval on the track, etc etc. What strikes you as a sensible way to go?
Based on our review, we believe that your installation would be uniformly illuminated by 10 units of our BR30 lightbulbs.
From what we have found on Home Depot’s website, there appear to be several 8-ft and greater track lengths that can be interlinked to accommodate any number of BR30 track light heads. These heads can be adjusted to any location on the tracks, which we believe should help illuminate specific prints and artwork that are on the walls of the space.
We believe that utilizing five track lighting heads on each side of the ceiling support beam should provide evenly distributed light across the entire space, though you may find benefit in some fine-tuning. Hopefully, this type of installation allows you to illuminate just the portions of the walls that you would like.
If you wind up preferring our A19 or A21 bulbs instead of the BR30 lights, please let us know and we will gladly provide you with a prepaid return label so that the unneeded items can be returned to us for a refund.
I will check out Home Depot for the track pieces and see what I can configure. Just to clarify, the lighting in the two parallel tracks (ie using BR30s) will be used to illuminate the vehicle below only. I will have separate, conventional recessed lighting (two units) to light the wall where I have some artwork. So the entire focus of the track lighting is to properly illuminate the red car.
The garage floor will be roughly 9' below where the bulb on the track will be. For uniform lighting do you recommend a particular interval on the track for the BR30?
As our BR30 lights have a beam angle of 120 degrees, we typically recommend placing them no further apart than the distance between the lights and the floor or illumination target.
As the track lighting will be 9’ from the garage floor, we would recommend installing the lights upon the track no further than 9’ from each other.
Focusing on the BR30s, I think I'm pretty well ready to move on this thing.
-The ceiling is 9'3" and the range from the bulb to the target will be something less as of course it will be mounted in a head suspended from the track.
-The distance between the two parallel tracks is 142". This dimension may shrink slightly based on where the darned ceiling joists are.
-I've spaced the heads (each with a BR30 bulb) at 4' intervals on the track
I want both tracks to be dimmable in tandem, on a single circuit which I'm thinking should be pretty straightforward.
Please wade in with any thoughts on my plan of lighting the space with 10 heads (ie 5 on each track). Also, I would appreciate your insight on Kelvin. Is there a standard? Given the application (ie illuminating a red car) should I be looking at 4000? 5000? Finally, where can I find the R9 values for your BR 30 bulbs?
Based on the details provided, we might recommend the 5000K color temperature option of our Full Spectrum E26 BR30 LED Bulb.
While 4000K is a common ‘neutral white’ color point for retail and office spaces, the 5000K option can be very beneficial for installations where color accuracy is important.
Which LED Light Color Temperature Should I Choose?
Difference Between 5000K and 6500K Bulbs
Though the 4000K BR30 photometric report is currently available, we do not yet have test data for the 5000K and 6500K BR30 options.
Does Waveform recommend any one brand of these things over the other? Similarly, what specific dimmer do I want to buy that's most compatible with your Full Spectrum E26 BR30? I see many things out there referring to an R30-shaped bulb....are the BR30 and the R30 the same size?
In the track department, my understanding is I should be looking for the H spec track, which of course will necessitate I have H spec (Halo compatible) heads.
Unfortunately, we do not have any specific track lighting brands or models that we would recommend, and we do sincerely apologize for any complexity this may add to your purchase planning.
That being said, we are happy to confirm that our BR30 products are compatible with the dimming technologies used within most products on the market.
Based on our understanding, the R30 and BR30 lightbulb are largely interchangeable with fixtures as they are the same size. Further, the BR30 has a narrower beam angle due to the more directed reflector within.
Does your BR30 bulb compatible with 6” recessed cans fixture?
I have 6” recessed cans with halogen PAR38 75w bulbs. I want the light brightness and color appearance of the halogens in LED. I see you have R30 bulbs that would meet my needs. Do you also have R40? If not, will the R30 size work to my satisfaction? Or can you refer me to a company that makes an R40 that would meet my needs?
The closest product in our catalog to halogen output would be our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential. So long as the fixture utilizes the standard E26 base, we believe that our BR30 bulbs should be compatible.
That being said, we can confirm that we do not currently have BR40 bulbs available. Further, we, unfortunately, do not have any third-party products that we could recommend, and we do apologize for any impact this may have on your purchase planning.
If would like to try our BR30 bulbs for your installation, please feel free to take advantage of our 30-day return policy. Simply let us know which items are unneeded, and we will provide a prepaid return label so that the items can be returned to us for a refund.
Flicker-free with the Whitest Light Color for Kitchen Can Lighting.
I wanted to order some flicker-free bulbs. Which ones are the whitest light color? I was going to put them in my kitchen in can lighting.
Based on the details provided, we would recommend the 5000K or 6500K versions of our Full Spectrum E26 BR30 LED Bulbs. These lights are designed for recessed ceiling lighting and offer full spectrum output and a high CRI of 95+.
If you would like to try this product in the other available color temperatures, please feel free to take advantage of our 30-day return policy if any items are unneeded. Simply reach out, and we will gladly provide a prepaid return label for those products.
I have to use flicker free ones. Our home person was recommending a flicker free one that you just came out with. Do you know which one that is?
Based on the details provided, it sounds as though you may be referring to our newly launched CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulbs.
These flicker-free products are available in the 4000K, 5000K, and 6500K color temperatures, and have a greater light output of 1600 lumens compared to our BR30 and A19 bulbs which offer 800 lumens.
What does the color temperature number mean? What's the difference between them?
Generally speaking, 'color temperature' is a measurement of how 'cool' or 'warm' the light being output by a source is.
For example, residential installations such as living areas and kitchens often benefit from ‘warmer’ color temperatures that are lower on the scale, such as 2700K and 3000K.
In comparison, higher color temperatures such as 5000K or 6500K are much ‘cooler’ and mimic natural daylight. These options are often very useful for art production and industrial purposes.
As can be noted by the below post, the color temperature options benefit different installation areas due to differences in output.
Which LED Light Color Temperature Should I Choose?
Can I use 2 tubes in a 4-tube fixture?
I just bought your “centric daylight, full spectrum, flicker-free T-8 in the 4-pack. I love the color of the light, but 4-tubes make it too bright. Is it ok to just use 2 tubes in the fixture? It’s the shop light style, covered with acrylic. It hangs a couple of inches below the ceiling, NOT recessed in the ceiling. We’ve had led tube lights from Lowe’s in it for 3 years but didn’t like the warm color of the tubes we had. So can we just install two tubes?
Based on experience, we have found that most fluorescent fixtures allow for operation while only being partially filled with tube lights.
As such, utilizing only two units within your four-bulb fixture should prove to be safe for operation. That being said, we would likely recommend looking for the light fixture user guide online, likely published on the manufacturer's website, to ensure functionality.
LED Bulbs Recommendation for Art Studio Room
I am looking at lighting for an art studio room, size of approximately 11x12 ft. I think the bulbs I need are the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. For this size room, how many bulbs would be needed in a shop light fixture?
In the hopes of clarifying, it might be helpful to know that the NorthLux™ 95 CRI LED Shop Light Fixture ships with pre-installed LED lighting within, and would not require any bulbs to be installed for operation.
Based on my review of our Lumen Estimation Calculator, it appears that ~10,379 lumens would be required to evenly illuminate your studio space for artwork creation.
If the NorthLux™ 95 CRI LED Shop Light Fixture is indeed preferred, it appears that two to three shop light units would be able to meet that goal, each providing 4200 lumens.
If a third-party shop light fixture were to be used, the Lumen Estimation Calculator recommends 13 units of the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, each providing 800 lumens.
How do I configure these to hang them? Is there a fixture that holds 2 or 3 bulbs, or do I have to hang them individually?
The LED Shop Light fixture does not require any lightbulbs for functionality, as the light sources are installed within the product housing.
On the other hand, the BR30 bulbs can be used in most common residential fixtures, such as floor lamps and recessed ceiling lighting.
In the hopes that it proves to be helpful, track lighting systems are often utilized for installing BR30 lightbulbs. Based on my review, several of those fixtures appear to be available from retailers such as The Home Depot and Lowe’s.
Compatible Lighting for Recessed Cans for Art Studio
I have a small room I use for an art studio. The room size is 8 by 10. It has 9-foot ceilings and windows on two of the four walls. Installed are four overhead recessed lights for lighting on cloudy dim days and at night. I have 2 problems. One is the incorrect temperature of light, and (2) shadows on my work table from the lights above. Can you recommend bulbs/lamps for my recessed cans that will be best for the art studio and diffuse the light to minimize the shadows?
First of all, regarding the color temperature, we recommend using either 5000K or 6500K color temperature lamps under our NorthLux brand to ensure that the light color matches the natural light color coming in through your windows. For recessed light fixtures, the BR30 lamps are generally the most popular option.
We're uncertain if your current lights are for residential use (e.g. 2700K or 3000K), but a daylight-calibrated color temperature of 5000K or higher will ensure that the light appearance will match that of natural daylight.
Since you mention that you have two windows, we assume that at least one of those would not be north-facing. As such, the 5000K may be a better fit for you, rather than the 6500K. Here is an article that you may find helpful in further refining your options:
Finally, as far as the shadows and light distribution are concerned, unfortunately, the fixed positioning of the ceiling fixtures will limit our ability to address this issue directly. As an alternative, we would recommend supplementing the light from the sides of the studio space as much as possible, as this will help "fill in" any shadow spots that are cast by the overhead ceiling lights.
A simple solution might be to use our A19 lamps in a floor lamp fixture, but many of our customers have used our T5 linear fixtures which offer a more versatile installation option.
Could your LED strip lights be configured for a ceiling-mount fixtures?
I'm an artist looking at studio lighting options, and I'm leaning toward purchasing one or two of your NorthLux 5000K shop lights for my studio. But I was hoping to flush mount a fixture instead, and there aren't many great options available. I do see a lot of nice LED flush mounts elsewhere but without the essential high CRI lights that I need as an artist. Would it be possible to get a flush mount like this (link here) or one at Lowe's and replace the strips in that with your LED strips? Or (fingers crossed). Do you have any plans for a nice-looking flush mount fixture in the works?
Unfortunately virtually all LED ceiling lights are not designed with replaceable LED strips, so while we totally agree with the concept, this would not be a practical solution.
We've received numerous requests for ceiling-mount fixtures with high CRI LED light sources, and hopeful that we will be able to introduce a product line with these features in the near future.
For the time being, we would suggest the shop light fixtures (as you mentioned), our T5 linear fixtures or our T8 lamps + fixtures as the closest alternative options which would provide the high CRI you are looking for.
Will your A19 LED bulbs be compatible with bowl fixtures?
I am considering using these bulbs “CENTRIC HOME™ Flicker-Free A19 10W LED Bulb 4005C.27” in a semi-flush ceiling fixture with a large bowl, KICHLER 42025NI. In the past, I have had trouble with LED bulbs overheating and putting a plastic smell when I put them and semi-flush ceiling fixtures with bowls. Will this work, or should I avoid it?
Strictly speaking, our Centric Home A19 lamps would be suitable for use in the fixture you have as it does not appear to be considered a "completely enclosed" fixture.
It is a bit difficult to see from the fixture photos, however, whether or not the top of the fixture bowl is open. If there is another cover on the top of the fixture bowl, that may indeed block airflow, making it easier for LED lamps to overheat. Otherwise, we do believe that with sufficient airflow coming in from above, there should not be any serious concerns with respect to overheating.
What size and type of reflector and socket you'd recommend for BR30 bulbs?
I am curious about what size and type of reflector and socket you'd recommend for these BR30 lights.
Though we do not have any specific reflectors or sockets that would recommend, it might be helpful to know that our BR30 lights are compatible with all standard E26 base fixtures.
For example, would something like this work? Is that too much voltage or not enough?
Based on our review, it appears that the fixture provided would be useable with our BR30 lights as they are compatible with 120V AC, 50-60 Hz input. As such, we would not expect that any operational issues would occur when using our lights with this fixture.
I would like to figure out the ideal lighting setup for a wall in my painting studio. Currently, it's recessed in, creating a drop shadow in the top part of the wall. I am trying to figure out if I should get BR30 lights to direct from both sides (using a traditional reflector with light stands) OR mount the T8 LEDs below the recessed ceiling.
Regarding your painting studio setup, supplemental lighting from either the sides or below would be a great way to mitigate the issues with the drop shadow caused by the overhang.
As mentioned, the BR30 lamps have an E26 base and are compatible with reflector lamps such as the one linked below. These lamps on a light stand could work well for your needs.
Our A19 lamps, installed in standard floor lamp fixtures might also be an effective way to increase brightness in the studio area.
Alternatively, you may also want to consider our T5 linear fixtures, which can be mounted along the sides or even on the overhang itself. These light fixtures have the added benefit of being semi-portable when used with the magnet mounts; they can also be permanently fixed into the ceiling and wall locations using the screw mounts.
Will the BR30 LED Bulbs work outside the US?
I'm interested in "NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio" lights and I'd like to know if they would work in Israel. Electricity in Israel is 230 Volts, alternating at 50 cycles per second.
Unfortunately, the NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio are not designed for global input voltage, and we do sincerely apologize for any impact this may have on your purchasing plans.
As a primary alternative, you may be interested in the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product. These A19 bulbs are designed to be compatible with global voltage standards (90-240 V AC, 50-60 Hz) while offering a high CRI of 5+ and flicker-free output.
Though we have not been able to identify the standard lamp socket base common to Israel, it might be helpful to know that this line of products is available in both the E26 and E27 base standards.
Why your LED bulbs cannot be used in a closed fixture?
Can you explain why your bulbs cannot be used in a closed fixture? I understand that they cannot be used with a dimmer, but what about non-dimmable closed fixtures?
Our CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs contain hardware that is heat-sensitive and requires heat dissipation for safe operation. When these lights are used within open fixtures such as sconces or traditional lamps, the heat is easily able to dissipate through moderate airflow.
As an alternative, you may be interested in our A19 LED Filament Bulbs, which are suitable for fully enclosed fixtures without concern for component overheating. These lights are available in the most common color temperatures for residential installations (2400K, 2700K, and 3000K).
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.
Will the matching driver LD20W-36-C045 be compatible with D50 5000K T8 LED Tube Lights?
I am replacing bulbs that require "Matching Driver LD20W-36-C0450" Will this work?
Based on our review, it does not appear that the LD20W-36-C0450 ballast model that was shared is not among our list of compatible ballasts. When fixtures with incompatible ballasts are used with our T8 products, they will void the warranty and likely encounter early product failure.
That being said, it might be helpful to know that our T8 LED Tube Lights can be installed into fixtures by bypassing the ballast, thereby allowing for full operation. We have prepared a set of instructions for bypassing the ballasts within fluorescent fixtures, which can be found within the T8 LED Tube Light installation guide.
Which light fixture is better for an art studio?
I'm about to place an order for your T8 Fixtures. Which fixture is better for an art studio? Wrap Fixture with Prismatic Lens or Strip Fixture with Reflector?
The Strip Fixture with Reflector might be a good option for your art studio, as the reflectors on the product can assist with distributing the light output. The Wrap Fixture with Prismatic Lens was created to be a more aesthetically pleasing fixture design, though it does not necessarily add any benefit to the light output over the Strip Fixture with Reflector.
E14 and E27 Flicker-free LED Lights
I have a migraine and need flicker-free LED light bulbs (25 W and 60 W (I do not know how much that is in LED), and I need them in E14 and E27). I also need flicker-free fluorescent lamps (LED). I need a yellow light (not white or white-blue). Which of your products do you think is the best for me? I live in Sweden, how much is the shipping for just a few of your products for me to test before I buy more?
While we do not have E14 bulbs, you may alternatively be interested in our 60W-equivalent (800 lumens) E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs. These products are compatible with global voltage standards, provide flicker-free light output, and offer a high CRI of 95+.
While our T8 LED Tube Lights and LED Ready T8 Fixtures are not compatible with global voltage, we might alternatively recommend our CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures. These fixtures are compatible with 120 – 277V AC 50-60 Hz, but will likely need a wall plug adapter for use in Sweden.
Why your LED bulbs can not be used in enclosed fixtures?
Can you tell me why your bulbs can not be used in enclosed fixtures? Is it because they generate heat? I am looking for bulbs I can use in enclosed light fixtures.
We can confirm that many of our lightbulbs require moderate airflow to allow for the dissipation of heat from the internal product components.
When these products are installed within enclosed fixtures that do not allow for heat dissipation, they will experience a higher failure rate.
As alternatives, you may also be interested in our filament bulbs, such as the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which are designed to be compatible with fully enclosed fixtures.
I'm unsure if the wattage on your filament bulbs will supply enough light for our current 3 bulb 60 watt indacesant kitchen fixture. Can you provide more information on that.
We can confirm that the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential is equivalent to 40W bulbs and has a light output of 450 lumens.
What kind of fixture should I use for the Avian bulbs?
What kind of fixture should I use for the Avian bulbs? I have a Quaker Parrot that I did not realize was not getting enough sun because of our awesomely made UV-blocking windows.
We, unfortunately, do not have any specific fixture recommendations, but virtually all fixtures with an E26 base should be compatible and work fine for the application.
Please do note, however, that our lamps do not emit UV radiation, so our product may not be a great fit if UV radiation is needed.
Can I use the Centric Home A19 bulb in Ceiling Fan Light Kits?
I'm interested in using your centric home flicker free A19 10W bulbs in my new home, including in ceiling fan light kits. I see on the web page that the bulbs are not suitable for enclosed fixtures. Does that mean that these bulbs should only be in non-sealed ceiling fan light kits? Eg - glass "bowl" light kits that don't seal at the top, or shades (separate for each bulb).
The restriction on our bulbs applies to completely enclosed ceiling fixtures only, and as such, they can safely be used in ceiling fan light fixtures as long as there is at least a partial opening.
Based on your description of the ceiling fan light fixture that you currently have, we do not see any issues with the enclosed fixture limitation.
Recessed Can LED Bulbs for Basement Lighting
What could I put in my ceiling, which is currently cans? And do you have an idea for how to light "fake windows" - I've read about 2'x4' LED panels. I'd like natural-looking light in the basement.
For recessed can lighting in homes, we typically recommend the Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential.
These products are dimmable and offer a high CRI of 95+, which can make quite the difference in low-light installation areas such as basements.
Do you have pendant-type fixtures for ABSOLUTE SERIES™ LED flex strips?
I'm looking for pendant-type fixtures up to 8' to install the ABSOLUTE SERIES™ LED Flexible Strip - 99 CRI. The lights will be used for critical color printing evaluation. Is it possible to purchase a designer fixture and replace the LED strips with your LED flex strips? Do you have recommendations?
Our ABSOLUTE SERIES™ LED flex strips are a great fit for color printing evaluation! The D50 color point should be an excellent way to ensure consistent and accurate color evaluation.
From an electrical perspective, this can certainly be done, but we are unfortunately not aware of any existing pendant fixtures that are designed with LEDs that can be replaced by the end user. In addition to mechanical fit, we would also need to ensure electrical compatibility as our ABSOLUTE SERIES™ LED Flexible Strip requires 12 volts DC to operate.
(We also have a 24-volt, linear module version which you may also want to consider).
Flicker-free LED Light in E27 Fitting for Physiotherapy and Yoga Basement Room
I'm looking for basic lighting for a basement room that has been set up as a practice room for physiotherapy and yoga. The light quality is important here because there is no daylight and the physiotherapists spend many hours in this room. Can your lamps be used in a European electricity network of 40Hz and an E27 fitting? The following features are important: - Sphere or bulb shape in retro look with filaments or opal glass. - Light color 3000K or adjustable between 2700-4000K (if flicker free) - CRI of minimum 90.
Unfortunately, we do not have any products available in our catalog that directly match the details provided in your email.
The closest matches available would be the E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulb or E27 CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb, though neither are able to offer adjustable color temperatures.
Does it matter if the bulbs do not fit entirely inside the canister?
Does it matter if the bulbs do not fit entirely inside the canister? 60-watt, CRI 95, 5000k Spotlights
Generally speaking, so long as the recessed lighting bulbs can fit securely within the light socket, it should not make a large difference whether the bulb end protrudes from the canister.
That being said, please note that as our BR30 and A19 bulbs are not designed for fully enclosed fixtures, we would recommend installing them within canisters that are not fully enclosed so that airflow can assist in heat dissipation.
E26 bulbs vs E27 bulbs
My wife purchased a bedroom ceiling light from Europe with an E27 socket base. So far installing an E26 bulb in the fixture has not worked and we now believe we require a true E27 bulb. Do you sell E27 bulbs? Any recommendations?
Though the E26 and E27 base standards are very similar, some small differences in product measurements can cause E26 bulbs to be incompatible with E27 fixtures, or potentially cause performance and safety issues.
That being said, we are happy to confirm that our E26 and E27 lights are compatible with global voltage standards, which means that our A19 E27 bulbs should function properly in your European fixture while using the North American voltage standard.
As we generally recommend 2700K color temperature for living areas such as bedrooms, we would recommend the 2700K E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulb (PN4007.27).
Are Lux24 and Ultra High A19 5W LED Filament Bulb available in E27 base?
Are Lux24 and Ultra High 95 CRI A19 5W LED Filament Bulb available in E27 base? What is the difference between CentricHome 3000K and FilmGrade 3000K? What is the M/P ratio for all CentricHome, FilmGrade, and Ultra High 95 CRI A19 5W LED Filament Bulbs?
I would also like to know if there is a much smaller output and size of power supply for the LED strip available. I'm looking to modify my R7s wall lamp to use LED strips and the power supply must be small enough to fit at the back space of the housing.
We can confirm that the Lux24 and A19 Filament bulbs are not currently available with the E27 base. We apologize!
Also, the 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb and the 3000K FilmGrade™ Flicker-Free A19 LED Bulb are identical products that are provided with unique landing pages for marketing purposes.
Further, the M/P ratios for the 2700K and 3000K are 0.49 and 0.55, respectively.
Lastly, we do not have any smaller power supplies, but third-party power supplies can certainly be used as long as they meet the minimum power capacity needs of the LED strip connection. Please see below for our online calculator which you may find helpful:
For LED strips, is flicker-free operation determined by the strips themselves or by the power supply? If the power supply is, what should I look out for to go with your LED strips for flicker-free operation?
We can confirm that the flicker-free functionality is a feature defined by the power supply, rather than by the LED strip light products.
In searching for a third-party power supply that would allow for flicker-free operation, we would recommend comparing the power output against the details within our own power supply specification sheet. So long as the output is compatible, we would assume that the LED strip lights would be able to operate flicker-free.
FilmGrade™ DC Power Supply for LED Strip Specification Sheet
What is the M/P ratio for all CentricHome, FilmGrade, and Ultra High A19 5W LED Filament Bulbs?
I have some questions about A19 bulbs:
Are Lux24 and Ultra High 95 CRI A19 5W LED Filament Bulbs available in the E27 base?
The Lux24 and A19 Filament bulbs are not currently available with the E27 base. We apologize!
Difference between CentricHome 3000K and FilmGrade 3000K?
We can confirm that the 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb and the 3000K FilmGrade™ Flicker-Free A19 LED Bulb are identical products that are provided with unique landing pages for marketing purposes. We do apologize for any confusion this may have caused.
I would also like to know if there is a much smaller output and size of power supply for the LED strip available. I'm looking to modify my R7s wall lamp to use LED strips and the power supply must be small enough to fit at the back space of the housing.
We do not have any smaller power supplies, but third-party power supplies can certainly be used as long as they meet the minimum power capacity needs of the LED strip connection. Please see below for our online calculator which you may find helpful:
What is the M/P ratio for all CentricHome, FilmGrade, and Ultra High 95 CRI A19 5W LED Filament Bulbs?
The M/P ratios for the 2700K and 3000K are 0.49 and 0.55, respectively.
8-ft T12 Fluorescent Replacement for Shop/Studio Lighting
I'm very interested in replacing the lighting in my shop/studio. I have 8' T12 fluorescent lighting that I replaced with LED, and they're hurting my eyes more than fluorescents do. I was told that 2700k and the high 90s or above CRI rating possible was best. I don't see an 8' replacement on your site, just 4ft. Is that correct? I'm feeling overwhelmed and confused with this project. Could you recommend lighting options for my shop with something as close to daylight as you have? Am I better off having rows of screw-in type bulbs everywhere or do you carry strip or tube lighting that you would recommend?
First of all, I suspect that the eye strain you are experiencing may be the result of hidden flicker in the new LED lamps, rather than a color specification issue. Here is a video that explains how you would be able to detect this using an iPhone: https://www.youtube.com/watch?v=QTVjokUy2Dw
Since your fixtures are only able to accommodate 8 ft lamps, we, unfortunately, would not be able to utilize them with any of our lamps. Without having to replace the fixtures entirely, however, you may be able to use our NorthLux T5 linear fixtures as a retrofit solution (https://store.waveformlighting.com/products/northlux-95-cri-t5-led-linear-light-fixture).
The T5 linear fixtures are available in 2-ft and 4-ft lengths and can be mounted inside existing fluorescent fixtures using the included magnet mounts. These could very well "replace" the 8 ft lamps without actually needing to use the same lamp sockets, and this could also allow you to repurpose your existing fixtures as housings for the new lamps.
These are flicker-free, and have 95 CRI and 5000K / 6500K light output, ensuring excellent color accuracy that matches natural daylight.
I was actually just looking at those calculating how many it would require to at least match the lumen levels I have now. Great CRI rating, though I was looking more in the 3-400k (max) bulbs as anything higher than that is just too blue for me. I have an eye condition and no longer wear the proper contacts.
It's a 3800 sq ft area so unfortunately it's going to require a number of lights to illuminate properly.
Determining the total brightness needed is indeed a bit tricky, as sufficient brightness is very important for studio work, but having too much brightness could lead to potentially unpleasant glare effects as you've experienced. We offer a lumen calculator on our website here, which may be of interest: https://www.waveformlighting.com/lumen-calculator
Based on the 3800 square feet input, the calculator suggests approximately 150,000 lumens for your space if you are looking to reach a sufficient illumination level for studio work (80 footcandles). This would require approximately 85 of our 4-ft T5 lights to illuminate the entire space with sufficient brightness.
Of course, based on your personal preference, 80 footcandles may be too bright and intense. We could definitely cut this down to half, to 40 footcandles using 43 of the 4-ft T5 lamps, which is the generally recommended brightness level for a standard commercial or office space installation.
What's the difference between the T-5 and T-8? Is that just a matter of what fixture you have?
In addition, I also meant to ask if the daylight tube bulbs work differently than the non-daylight ones. I'm expecting to have to replace all the sockets as I have a variety of lights that would complicate things to match. I think it would be best to just replace them all and start off with matching sockets. Can I assume these plug into power directly as others do? Or do they need some sort of ballast?
The primary difference between the T8 lamps and the T5 fixtures is that the T8 lamps require a fixture to house them (typically traditional T8 fluorescent fixtures), while the T5 fixtures are an integrated LED fixture that does not require installation inside a fixture.
Generally speaking, we would recommend the T8 lamps for customers who have an existing 4-ft T8 fluorescent fixture. You mentioned that you have 8-ft fixtures, which are unfortunately not compatible. As such, we would recommend foregoing the T8 lamps unless you had plans to reinstall new T8 fluorescent fixtures.
The T5 fixtures, on the other hand, do not require a separate fixture and can be installed in virtually any location. A fluorescent ballast is not required, and the product can plug into any wall outlet or extension cord.
Our daylight/non-daylight designations relate to color temperature and do not have any bearing on the installation configuration.
Sounds like T8's may fit the bill. I'm a fabricator, so if need be I can retrofit the 8ft fixtures or fabricate new ones with new sockets. Though purchasing T8 fixtures sounds best. I think we may still have some in storage actually.
Sounds like a plan! As long as the sockets are spaced at the correct spacing to accommodate the 4-ft T8 tube lights, there shouldn't be any issues there. From a liability perspective, we do need to mention that the company's official recommendation is to only use fixtures designed specifically for 4-ft tube lights, but from an electrical standpoint there should not be any issues operating the 4-ft T8 lamps.
The "CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light" can be used with both shunted and non-shunted sockets. Please see below for the installation manual showing the various permissible wiring configurations:
What's the highest wattage available? Is 1,800 lumens the brightest 4ft T8 you carry? My 8-footers are 110w @ 8,800k per bulb, with 4 in each bank.
The only as well as the highest wattage available is 18 watts at 1800 lumens each.
For the sake of confusion would you mind forwarding me links to the T5 and T8s you're referring to?
Please see below:https://store.waveformlighting.com/products/centric-daylight-full-spectrum-flicker-free-t8-led-tube-light https://store.waveformlighting.com/products/northlux-95-cri-t5-led-linear-light-fixture
Do the T8s need a reflector-type hood to be more efficient because the light radiates out? Or do they already focus downward?
The light is emitted at a 320-degree angle. A reflector is not necessary but may help in producing a bit more "useful" brightness.
Do you have a T8 LED Tube Light to fit the Phillips UltraLume F15T8/85U fixture?
The above sounds perfect however the length needs to fit a 17" (18"?) double-tubed Fluorescent Drafting Table fixture (the classic from 20 years ago - currently using Phillips UltraLume F15T8/85U 5000K bulbs). Do you have the NorthLux™ 95 CRI T8 LED Tube for Art & Studio bulbs in a size to fit these classic lamp fixtures? I think I may shift to 6500 or order sets of 4 of each D50 and D65 for viewing prints. And will the LED work in a Fluorescent fixture?
At this time, we currently only have the 48” length of the T8 LED tube light products available in our catalog. We apologize!
That said, we can confirm that our LED tube light products function in fixtures that utilize a compatible ballast. In case it proves to be useful, we have provided a link to the compatible ballasts below.
Additionally, these lights can also be installed utilizing a ballast bypass method, in the event that the pre-installed fixture ballast is incompatible.
Compatible Ballasts List
Do you have a ceiling dimmable light that could adjust color temperature/brightness level?
Do you have a kind of ceiling dimmable light, that could adjust color temperature/brightness level, with a remote, for residential, bedrooms? I am very sensitive even to high PWM flicker frequency, do you know how many "kHz" frequencies your product works on different brightness settings?
Though we unfortunately do have any fixtures that would be capable of all referenced features, you might be interested in either the FilmGrade™ FiveSpect 5-in-1 LED Strip Lights which can emit any visible spectrum, or our FilmGrade™ HYBRID LED Strip Lights which can be tuned between tungsten and daylight color temperature output.
Regarding the flicker sensitivity, you may also be interested in the FilmGrade™ DMX LED Dimmer & Decoder with 5-Channel Output, which is capable of PWM frequency adjustment between 500Hz and 30 kHz. Additionally, it might be helpful to know that this product can be used with the above Hybrid and FiveSpect products.
We recommend utilizing a third-party controller for adjusting the output of these products, as well as a mounting channel such as the Aluminum Channel for LED Flex Strips. Further, please note that these products would likely require more manual configuration than another pre-built fixture option might allow for.
Could you tell me an average competitor product, that claims to be flicker-free, how many kHz are use in their product?
Though we're not aware of the exact flicker rate of the products offered by our competitors, we can confirm that many third-party LED products can have a flicker rate between 15-75%, which is quite high.
We have provided a link to an instructional article from our website about flicker-free technology, which we hope proves to be useful.
Flicker-Free LED Lighting: https://www.waveformlighting.com/flicker-free-led-lighting
Why are your LED bulbs not recommended for closed-light fixtures?
I just purchased 6 of your LED bulbs. Why are they not recommended for closed-light fixtures?
We can confirm that several of our products are not recommended for enclosed fixtures due to the requirement for heat dissipation.
As LED products contain heat-sensitive internal hardware components, the bulbs will require a moderate amount of airflow to function properly and prevent overheating. Comparatively, traditional incandescent bulbs do not contain any hardware or materials within the fixture that are heat sensitive.
Do your A19 bulbs work in recessed ceiling fixtures?
I was wondering if your flicker-free A19 bulbs will work in recessed ceiling fixtures. I understand they don’t work in fully enclosed fixtures but these have at least the end of the bulb exposed to the air. These fixtures would normally take floodlights but I don’t think there is a flicker-free floodlight option, correct?
We're happy to confirm that the A19 products are compatible with recessed ceiling fixtures, and are best when used within fixtures that allow for moderate airflow.
If the A19 bulbs are connected to a dimmer without utilizing the dimmer functionality, the products should function properly. When using the A19 products with dimmers, you may encounter flickering or atypical functionality.
Unfortunately, we do not have a flicker-free BR30 product available at this time.
Would it possibly lessen the hazard of installing E26 bulbs in the E27 socket at 120V?
I read with interest your blog article "E26 vs E27 Bulbs - Interchangeable? Not Necessarily!", but it left me with a question. Apparently, there are lighting fixtures sold here in the US that have E27 sockets. While your article calls out the hazards of E26 bulbs in E27 sockets at 240V, it did not comment about E26 in E27 at 120V. Would that possibly lessen the hazard?
Though the design differences are slight, the small gap present between an E26 light installed within an E27 socket base can cause arcing or hazards that are separate from any potential voltage compatibility issues that might arise.
As our E27 and E26 bulbs both are designed for global voltage standards, we can confirm that the E27 versions can be safely used within fixtures designed for European or other voltages.
For example, if a European chandelier with E27 sockets was to be used with 120V AC North American voltage standards, we would recommend using our E27 A19 bulbs, as they are capable of being used with 120V AC voltage even though the base is typically used in global fixtures.
Are the following light fixtures compatible with your T8 LED Tube Light?
Are the following light fixtures compatible with your product: CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light?
Are there better T8 light fixtures that you'd recommend to be used with your CENTRIC DAYLIGHT T8 LED bulbs?
Based on the review, it appears that the Grainger and Sustainable Supply products are not compatible, as these fixtures are designed for 96” lights, whereas our T8 products are 48".
That said, it does appear that EnviroLite would be compatible - although we do not see technical data provided for the ballast within the fixture. It may be worth reviewing to be sure that the ballast within is compatible with our T8 lights.
If it is not, we can confirm that most T8 fixtures are compatible with our lights when installed via the ballast-bypass method.
Can you suggest a LED lamp works with an overhead cubicle florescent 48" BiPIN fixture?
We do not have LED lighting installed, rather 48 in BiPIN florescent tube light overhead. I want to replace it with full spectrum type lighting because the 'normal' lamps custodial installed are not very acceptable since I'm used to working from home office streaming in natural lighting. The custodian explains the district doesn't provide a 'special' lamp however I'll need to buy it but OK for installation. Is there a smaller package of lamps you'd suggest and will these lamps work in fixtures we have?
Based on the details provided, we might first recommend checking to ensure that the lighting fixtures in your office are compatible with our T8 LED tube lights.
Further, for office lighting, we recommend the 4000K color temperature of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are available in 4-Packs and offer full-spectrum light output with a CRI of 95.
Occasionally, older fluorescent fixtures utilize electronic ballasts which are incompatible with LED products. Though we do offer illustrated guides for ballast-bypass methods for such fixtures, this process may not be feasible for all office spaces.
That being said, we have attached a link to the list of compatible ballasts below, as well as the instructions for ballast bypass wiring installation.
Tested Ballast List:

If you would like to purchase a 4-Pack of our T8 LED tube light products to check for compatibility with the fixtures in your office, please know that we are happy to offer a 30-day return policy for all orders.
Are your LED bulbs compatible with a boob light?
I'm very interested in your products, but all of the fixtures in my apartment are "boob lights" and my GE bulbs get too hot in them and die horribly. Can I use your lamps in a fully enclosed fixture, or will I have the same problem?
Based on the details provided, we might recommend the Ultra High 95 CRI A19 5W LED Filament Bulbs, or the 2400K Lux24™ Circadian LED Bulbs, as they are designed to be used within enclosed fixtures.
The other bulb products in our catalog require air flow in order to dissipate the generated heat. As such, we would not recommend these items for the enclosed fixtures mentioned.
Do you have a 2700K flicker-free bulbs for enclosed fixtures?
I'm a happy Waveform customer, but I'm looking for a flicker-free bulb that can be used in an enclosed fixture, preferably 2700k or lower. Do you have any recommendations, or do you know of any products out there that might work?
Though unfortunately not flicker-free, the closest product matches in our catalog would be the 2700K Ultra High 95 CRI A19 5W LED Filament Bulbs, or the 2400K Lux24™ Circadian LED Bulb.
Further, we do not have any third-party products we could recommend as an alternative at this time. We apologize!
Can an E26 bulb be used safely in an E27 socket at 120V?
I read this post comparing E26 and E27 bulbs and found it very informative. But there is one question I have that wasn't addressed. Can an E26 bulb be used safely in an E27 socket at 120V (I know you said no at 240V)? I ask because I have a couple of euro-made chandeliers rated for 220V that I will be installing in the United States, so it will be at 120V. What bulbs are the best fit and safest for this situation? Do you sell anything that would work?
Based on the details provided, we would instead recommend utilizing our A19 E27 bulbs for your chandeliers, as they are compatible with global voltage standards - including the North American standard of 120V AC.
As the measurements of the E26 and E27 sockets are different enough to cause some potential for electrical arcing or issues, the E27 would be safely compatible with the chandelier sockets.
Can I use LED strips to replace the bulbs in the fixtures?
I just moved into a home with a huge basement. I think each room has 6, 2x4 Fluorescent fixtures. Would one of your flicker-free strips work as a means to replace the bulbs in the fixtures? If so, what would I need per fixture to make them dimmable?
Generally, we recommend installing our T8 LED tube lights as replacement lamps for existing ceiling fixtures. I do note that you are looking for dimmability, however, and that is unfortunately not supported with our T8 lamps at this time.
Our LED strip lights could be installed in ceiling fixtures as a retrofit solution, though we, unfortunately, do not have any instructional literature or detailed guidance on accomplishing this. From an electrical standpoint, this could certainly be achieved using a combination of our TRIAC dimmable power supply with our LED strip lights.
For example, please see below for a layout diagram showing how these can be connected:
T8 LED Tubes for Seed Starting & Ballast Compatibility
Is the PhotonTube part number 4024.65.4P compatible with a Phillips Advance REB-2P32-N ballast? I found a ballast compatibility document that lists that ballast as being compatible with your part number 4020 LED tubes. Is that document now obsolete? What is the recommended T8 LED tube height range above plant seedlings? I'm considering a 4 FT 4-lamp T8 LED fixture for my plant shelves. Currently, I'm using a 2-lamp 32-watt T8 fluorescent fixture, and its underperforming.
We're happy to confirm that as our current T8 LED tube light products are of the same family line, the ballast compatibility listed within the document referenced is still current and able to be referenced.
As our T8 LED tube lights will emit a far lower amount of heat than traditional horticulture lamps, heat damage to the seedlings is less of a concern. As such, we recommend placing the lamps as close to the seedlings as possible without touching them. That said, different plants might require more precise distances from the light to receive the maximum benefit.
Is Centric Daylight T8 LED Tube compatible with Keystone Ballast fixture?
I am building a new house with a 3-car garage for detailing, so need high CRI. I have 11 linear ceiling fixtures, each for 2 T8 bulbs. Are your centric daylight 5000K compatible? Can you tell if they will be flicker-free in this fixture? They are currently using Keystone ballast, model KTEB-232RIS-1-TP-SL. The specific model is not on the tested ballast list.
Based on my review, I can confirm that the ballast provided has not previously been tested with our T8 LED products.
That being said, it does appear that the KEYSTONE KTEB-332-UV-IS-N-P ballast has been tested as compatible. If the items are of the same manufacturer product family, I do believe that they might work well!
Alternatively, as previously mentioned, the T8 LED lights can always be installed using a ballast-bypass method if the ballast is incompatible.
Do you make full spectrum LED lighting for recess can downlights?
Do you make full spectrum LED lighting for recess can downlights trim in 4" & 6"
We do not have any direct ceiling lamp replacements, but we do offer BR30 retrofit lamps which may be of interest. These have a diameter of 3.75 inches and should work well in both 4" and 6" ceiling fixtures.
Please see below for the product link below!https://store.waveformlighting.com/collections/br30-bulbs/products/ultra-high-95-cri-e26-br30-led-bulb-for-home-residential
Full Spectrum and Flicker-free LED Recessed Lights
It has been recommended that the recessed lights in my autistic son’s basement bedroom with a low ceiling be full spectrum non flicker. What would you recommend? I find LED lights generally extremely bright. Also, I’ve read that the flicker has more to do with the electricity going to the lights rather than the bulb. Should I change the very old dimmer switch?
Though we would usually recommend our BR30 products for your recessed lighting, (such as the 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential product) these items are unfortunately not flicker-free. As such, these products might not be a good fit for the installation.
I ordered 6 x CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs (2700K). It says they are not suitable for enclosed fixtures. Would they be okay for semi-enclosed? I have a couple standing lights with 3 x cones that house the bulbs. I also have the cone desk lamps.
We're happy to confirm that most semi-enclosed fixtures should be safe to use, so long as there is adequate venting for heat dissipation.
For context, unless a fixture has a way of easily dispersing the heat generated by the bulbs, the hardware within the bulbs can overheat and cause the product to encounter errors.
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.
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.
Can an E27 LED Light Bulb be safely used in an E26 fixture?
I read your article and it was very informative. In general, bulbs with an E27 designation are safe to use in E26 lamp holders, but E26 bulbs may pose an electrical safety hazard when used in E27 lamp holders and 240V AC.
Quick question: I purchased these two bulbs (LED Light Bulb 3D 220V A60, LED String Light Bulb E27). From what I read, I think they should be safe to use in the USA. I just wanted to confirm that an E27 LED Decor Light Bulb can be safely used in the USA.
In general, as long as the voltage inputs are compatible, E27 lamps can be used in E26 fixtures without any significant concerns.
That being said, we, unfortunately, cannot provide any assurances regarding products purchased from third parties and would recommend reaching out to the manufacturers of your light bulb and lighting fixture for further guidance.
Replacing an E27 with E26 Fixture
I have just read your great article on "change E26 to E27". I have 3 lamps from Europe with E27 sockets. Are the adapters reliable? Alternatively, is it a fairly easy job for an electrician to change the socket to E27?
Based on our research of the E27 to E26 adapters available locally and through online marketplaces, there appear to be many products available that could be used for your lamps. As we have not personally similarly modified any fixtures, it is difficult to say how reliable the products are.
Having recently spoken to some local electricians regarding lamp base replacement, we have been informed that the process of replacing an E27 base with an E26 base is fairly easy. The most complicated step appears to be finding an E26 base that can neatly fit the lamp socket, given the variation in lamp fixture models. Also, any required wiring adjustments should be fairly straightforward.
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.
Ceiling Fan Lights Recommendations
I'm trying to find bulbs for a ceiling fan that holds 4 bulbs. I do notice any of my lights that flicker so that's a big deal for me. Any suggestions?
I was thinking about buying a centric home with 95 bulbs but I don't know if I prefer 2700 or 3000. Can't make up my mind today but I'd be glad for some advice.
I do like some smaller shaped lights from Lowes (utilitech) but they don't seem to have them anymore. Do you make any smaller bulbs but still with a medium base?
Based on the details provided, we might recommend the 2700K or 3000K option of the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb product, which is designed to offer flicker-free functionality.
Regarding the selection between 2700K and 3000K, your choice may come down to personal preference. For living rooms and bedrooms, we generally recommend the 2700K option, whereas, for kitchens and dining areas, we would alternatively recommend the 3000K option.
It might also be helpful to know that we offer a 30-day return policy. If the color temperature selection winds up not working well for your space, simply let us know and we would be happy to issue a prepaid return label.
Regarding the bulb sizes currently available, we can confirm that we currently do not have any bulbs smaller than A19 available at this time. However, we are looking into expanding our product line within the near future, and hope to include more standard sizes.
Will 95 CRI BR30 6500K LED bulbs fit any fixtures?
I need help with proper lighting for the new salon. I know I need 6500k 90+cri. I see your artist bulbs are perfect. However, will those bulbs fit any fixtures, if not what kind do they comply with?
We are happy to confirm that our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio and NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio products are designed to fit within any fixtures that utilize the standard E26 base. For reference, the E26 base is a common standard that you would likely see in the most floor and table lamps.
As such, these products should not require any specialized fixtures for operation.
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:
For a list of the ballasts that are compatible with our T8 LED tube lights, please reference this link:
LED Lights in Overhead Soffit to Reflect Off the Ceiling
I generally sit in that recliner at the far end to read. Want to put sufficient light in the overhead soffit to reflect off the ceiling and illuminate the read. The table lamp shown is decorative the task light, barely visible by the chair, is what I use now. Has an LED bulb in it. Glares for the wife seated on the couch. It works well if I bring it down close to the read (magazine or newspaper) bulb is white.
It sounds like we have a few lighting fixtures in your space. To start, are you able to confirm what type of lamps or bulbs your fixtures can accommodate?
For example, the soffit looks like it may accommodate fluorescent fixtures, but it's a bit difficult to tell from the photo.
Similarly, are the table lamp and task light standard fixtures that use medium-screw Edison bases (E26)? (E26 is the most commonly seen, traditional screw-in lamp type with a base that is approximately 1 inch in diameter).
Once you can let us know what types of lamps may be compatible with your existing fixtures, we'll have a better idea of what options we have available for you.
Additionally, can you let us know what challenges you're facing with your existing lighting - is it the color, clarity, brightness, or a combination of these factors?
The soffit has a string of incandescent mini lights, circa 1992. We do not use the table lamp but it and the task light use standard e26 screw-in bulbs, the problem is insufficient illumination. The task light if I bring it close to the reading material will work but is ungainly and if it is set higher is not quite enough light but glares at anyone sitting on the couch. I had thought that linear LEDs in both soffits above the chair reflecting off the ceiling might work but leave that to your expertise. Using dimmers they could also provide illumination for the room. The soffit runs on three sides of the room.
We are in full agreement that improving the brightness from your soffit lighting fixture would be the best approach here to simultaneously increase brightness without causing additional glare issues.
Unfortunately, despite their ubiquity, standard light bulbs induce significant amounts of glare due to their high brightness levels from a relatively small size.
Our first thought here would be to recommend our CENTRIC HOME LED strip lights in 3000K. These LED strip lights emit approximately 450 lumens per foot, which is approximately equal in brightness to a 40-watt incandescent bulb.
It's a bit difficult to determine from your photo, but my best guess would be that your soffit is approximately 10 feet long. If you were to install the LED strip lights across the entire soffit, this would provide you with approximately 4500 lumens, or 400 watts worth of incandescent bulb brightness.
The LED strip lights could of course extend and span multiple soffits across the three sides of the room as you suggest.
The LED strip lights do require some in-wall wiring and assembly work, but I do believe that this would be an excellent option for you. Below is an example wiring diagram that shows how the LED strips can be wired to a wall dimmer:
Sometimes sitting on the end of the couch to utilize the halogen Torch which almost does the job but could be better. The new light needs to be dimmable, and maybe the color change?
Each one of the curtains is approx 6 ft across giving us approx 12 ft of the strip light. Approx 5500 lumens per your calculations. You mentioned 3000 Kelvin. Is that overly yellow for reading? Are your strip lights disabled and what dimmer do you suggest for the best performance?
Is there an approved dimmer for 3-circuit control? I note that LeGrand makes a couple although I am partial to Lutron.
I personally do not believe that 3000K is "too yellow" although that would certainly be within the realm of personal preference. Do you know what the color temperature of the lamps in your current space is, and what your thoughts on those might be? (Incandescent bulbs are typically 2700K and lower).
To cover the distances you quoted, you will likely need three sets of 16.4 ft LED strip reels, each with its own dimmable power supply. The cost estimate is as follows:
CENTRIC HOME™ LED Strip Lights for Home & Residential: $99 ea
TRIAC Dimmable Power Supply for LED Strip: $139 ea
We do not have any three-circuit control suggestions, but we do have a list of tested dimmers which are available here:
The reading lamp has a 790-lumen GE REVEAL built therein. It is I think overly bright white. If I bring it clues to the reading material it works but is glary with poor contrast and if further away not bright enough but not heavy. The soffit has a string of very old very small incandescent. I think we might try one set in the two soffits over the Chair to see how this indirect lighting works.
We believe the GE Reveal lamps use a modified 3000K spectrum. If you find the incandescent lights in the soffit to be acceptable from a color perspective (i.e. not too yellow), then 2700K could also be a good option for you.
Below is an article that might help choose between the two options:
Avian Bulb Placement and Fixtures
Would it be better to use an overhead ceiling fixture in my bird room or something closer to their cage, like a swag? Would a gradual dimming simulate natural sunrise and sunset?
We generally find that widely illuminating a large area using a ceiling fixture is preferable to close-up lighting methods, as this better simulates the effect of natural daylighting across the entire sky.
Gradual dimming would indeed also provide a better simulation of the progression of natural daylight throughout the day, although implementing an automated solution here would be some what challenging.
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.
BR30 vs A19 Bulbs for Artist Studio Space Lighting
I want to use the NorthLux 95 CRI E26 A19 LED bulbs in track lighting for a small space of 5 x 6 feet. How many bulbs would you recommend? Can you recommend a source or fixture that would be appropriate for the space?
Based on the details provided, we estimate that your 5x6 space would benefit from roughly 2,389 lumens to be properly illuminated for artwork creation.
As each of the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio products offers 800 lumens, we estimate that three bulbs could work well for the track lighting in your studio.
While there is not a specific light fixture that we could recommend, it might be helpful to know that our BR30 products are compatible with the standard E26-base track lighting systems that you might find in your local hardware stores.
Are there pros and cons to ordering the NorthLux 95 CRI E26 A19 LED Bulb instead? I see it is not dimmable, and the BR30 bulb is dimmable, but otherwise, I don't understand how they would differ in application. Can I use the E26 fixture with this also?
We're happy to confirm that the A19 bulb is compatible with E26 fixtures and that the performance will be largely the same as the BR30 bulb. The primary benefit offered by the BR30 bulbs is the narrow beam angles, which can be quite useful for track lighting systems with directional lighting.
However, if the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product winds up not working well in your space, it might be helpful to know that we have a 30-day return policy. Simply reach out to let us know, and we will issue a prepaid return label.
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:
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:https://store.waveformlighting.com/products/photonblast-led-grow-light-fixture
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:
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).
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.
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:
If the fluorescent ballast is not listed, you will want to remove or bypass the ballast from the fixture.
Choosing between T8 LED Tube and LED Strips for an Existing Electrical Boxes
I'm trying to choose between tube and strip lights and I need info on how I can hook it into my existing ceiling outlet box.
While each installation can differ, we generally recommend using our LED tube lights if there is an existing 4-ft fixture already in place. Our LED tube lights can be used without a ballast and therefore can be used without any additional electronic components.
LED strip lights, on the other hand, can provide you with some additional versatility and installation options. This approach, however, will require additional wiring and configuration, including power supply units and LED strip assembly.
I have six separate track lights on separate dimmer switches. The reasons they interest me are that they look to be very low profile and you have a 99 CRI strip light but only 95 CRI tube lights. Are there any other advantages or disadvantages I should be aware of for strips vs ubes? If I go with the strip light option, what do I need to do? How does it connect to the end feed and will the extra transformer fit inside the end feed? Will I need new dimmer switches? I currently use these(Lutron CTELV-303P-WH Skylark Contour 300W Electronic Low Voltage Single Pole / 3-Way).
Since you don't have a fluorescent fixture at all, the LED strip light option is definitely worth considering.
The challenge with installing an LED strip light in a location like this is that the existing track systems operate at a completely different voltage type and level. Typically, they are 120 volts or 12 volts AC, while the LED strip lights require 12 volts DC.
As such, the electrical wiring and systems inside the track lights will not be useful here and will need to be bypassed completely.
Below is a configuration diagram for a simple LED strip setup:
You will see the TRIAC dimmable power supply, which is the key component here that you will want to determine where you can fit this in your current installation. It is a somewhat bulky device and you will want to ensure it is installed in a location compliant to local electrical code. (Most frequently, it is installed inside of a junction box mounted inside of the wall).
The TRIAC power supply appears to be 9 inches, so it won't fit in the current electrical box in the ceiling. Could I just purchase your junction box and attach it to the ceiling? Do you sell it in white? Alternatively, I could install the TRIAC in the attic near the switches, but then it would need to feed into the current wires that run to the ceiling position. I'm thinking that those standard wires must be different than the ones needed for the DC, is that right? If so, I guess the TRIAC has to go right next to the strip lights.
We are not sure about the electrical code requirements and considerations of mounting the junction box on the ceiling, so that is something you will want to confirm before going down that path. The junction box is unfortunately not available in any other colors.
The concern with installing the TRIAC dimmable power supply far from the LED strip lights is that large distances between the power supply and LED strip lights can result in voltage drop, whereby the brightness of the LED strips become diminished by the reduction in voltage supply. Generally, we recommend keeping the LED strip sections within 32 feet of the power supply unit to reduce the impact of voltage drop.
My understanding is that your tube lights are not dimmable, is that correct?
That is correct. We agree that the LED strips would be the best option for a dimmable + flicker-free lighting solution.
Do you sell L pieces for the aluminum channel so I can turn corners with the flex strips?
Unfortunately we do not sell any "L" shaped corner pieces. The best way to accomplish this would be to solder wires directly between the LED strip segments that meet at the corner. The aluminum channels can also be cut at 45-degree angles to create a gapless 90-degree turn.
Do I need the centric series power supply rather than the triac to get flicker free?
The most recent batch of TRIAC dimmable power supplies is also now rated flicker-free. Therefore, you will be able to use the TRIAC dimmable power supply and achieve flicker-free and dimmable light output.
Do you sell a junction box that covers the centric?
We do not sell a junction box for the CENTRIC SERIES power supply. We would recommend going with the TRIAC dimmable power supply since it also provides flicker-free light output.
Can I connect two separate 8 foot strips to one power supply?
Yes, they can be connected "in parallel" - please see the blog post below:
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:
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.
Impact of the Enclosed Fixture on Light Output
What happens to the effective spectrum of a bulb if it is used in a lampshade, or in an enclosed fixture with a glass cover?
Most glass covers and lampshades have a minimal effect on the spectrum of light emitted by our products. Generally speaking, the whiter (clear/translucent) the material, the less effect it would have on the spectrum.
Unless the lampshades or covers have a significant color/tint to them, you will most likely not observe any color or spectral shifts.
Does Feiss Issen 2-Light Flush Mount Fixture compatible with your A19 Bulbs? ￼
I currently have 8 Sylvania 21942 - FO25/741/ECO T8 Fluorescent lights in my L-shaped kitchen and each leg of the L is approximately 12'x7'. Each of these bulbs is 25W, 4100K, and 1755 lumens. I'm switching out the old fixtures and replacing them with 3 Feiss Issen 2-Light Flush Mount FM504SN. It has a closed round glass shade: D: 13.5" H: 1.25" and uses 60W A19 medium incandescent bulbs. I'd like to use LEDs instead, being mindful that the light is closed, not open. Any suggestions?
Based on our review of the Feiss Issen 2-Light Flush Mount product, it appears that while otherwise compatible, the fixture is completely enclosed.
As our A19 bulbs would require a moderate amount of airflow for heat dissipation, these may not be the ideal fixtures for use with our A19 products.
However, we would be more than happy to review any other light fixtures for product compatibility.
Is the BR30 LED Bulb rated for use in recessed fixtures?
Is the “Ultra High 95 CRI BR30 LED Bulb” 4011.30/4011.40 rated for use in recessed fixtures (ceiling cans)?
The BR30 lamps can safely be used in the ceiling can fixtures as long as they are not sealed off. They are unfortunately not rated for enclosed fixture use.
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:
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.
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.
Fluorescent Fixture with Independently Controlled Bulbs
I am trying to source a fixture with multiple ballasts or a "smart" circuit to control each bulb in a T8 fixture independently. Ideally, at least 3 bulbs- 2 different wavelength blacklight bulbs and daylight. Do you know if any fixtures allow for individual control of fluorescent tubes?
Unfortunately, we do not have any specific product recommendations which offer the functionality described.
However, if you do find such a product we would be very interested to hear about your experience using it.
Can I plug the realUV LED Strip Lights into a ceiling fan fixture?
If I replace a ceiling fan, can I plug the wires into the old ceiling fan wires and have it work off the light switch?
Thank you for reaching out! Unfortunately our UV LED strip lights are not designed to be mounted into a ceiling fixture and would therefore not be an appropriate installation location.
As an alternative, we would perhaps recommend using our UV flood light, which can be plugged into a switched outlet. Please see below for the product link and let us know if you have any further questions.https://store.waveformlighting.com/products/realuv-led-flood-light
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!
What is meant by "enclosed fixture"? And why is this an issue?
You note that the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb is not suitable for use in an enclosure. Can you explain more about what you mean by an "enclosure" and why this is an issue? Is it a heat issue? I have a circular fixture with a 1/4" opening between the top and bottom plates and the center glass piece. Would this be OK?
Some of our products, including the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb, contain electrical hardware within the base of the bulbs which is heat sensitive. As such, these products are known to encounter issues when they have been installed within fixtures that do not allow for moderate airflow.
For instance, a ceiling fixture that is completely enclosed by the glass would not allow for the heat generated by the bulb to dissipate, whereas a wall sconce with an opening would more easily allow for sufficient heat dissipation.
Based on the description provided of the light fixture, you may not encounter heat issues as the fixture appears to allow for moderate airflow.
Can I hardwire the LED Shop Lights to the ceiling?
Would an electrician be able to ‘hardwire’ the Shop Lights to the ceiling replacing the regular ceiling light? I’m trying to figure out how to change the light over my work table without having cords hanging from the ceiling.
The shop lights are unfortunately not designed to be hard-wired and modifying the product is not recommended and would result in voiding the warranty.From a purely electrical standpoint, however, the fixture could be configured to be connected directly to the wiring in your ceiling/walls and would operate without any performance issues. We would recommend consulting with your electrician as well as fire and safety regulators for further guidance.
As an alternative, we would perhaps suggest installing ceiling fixtures that can house our T8 lamps, which can be used to provide the same level of light quality as shop lights.
E26 vs E27 bulbs - Are they interchangeable?
I read your blog entry on the interchangeability of E26 and E27 bulbs (https://www.waveformlighting.com/home-residential/e26-vs-e27-bulbs-are-they-interchangeable) with interest. In the Bottom Line section, you state that "E26 bulbs should not be used in E27 sockets. I live in the US, and recently received a nice lamp as a gift from a UK relative. I can swap out the wall plug relatively easily, but the bulb holder is of a strange design that's difficult to remove/replace. Since I'll only ever be using E26 bulbs here on 120V AC, from an electrical safety perspective, I should be OK, right?
While we cannot guarantee or be liable for any safety concerns, our general understanding of lamp fixture design would suggest that using your E26 lamps in an E27 fixture at 120 volts would be a lower safety concern than doing the same at 240 volts.
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:
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:
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.
Fixture Style UV LED Lighting
I have a customer looking for the following: 1st Light UV-A Nanometers: between 315-400nm Fixture Style: Can hang overhead Coverage: A minimum of 3x2 feet for testing purposes 2nd Light UV-B Nanometers: between 280-315nm Fixture Style: Can hang overhead Coverage: A minimum of 3x2 feet for testing purposes 3rd Light UV-C Nanometers: 250nm and below (the lower the better) Fixture Style: Can hang overhead Coverage: A minimum of 3x2 feet for testing purposes.
We are happy to offer the realUV™ LED Strip Light product in both 395nm, as well as 365nm. Each version of this item is available in reels of 3.2 ft (1 meter), and 16.4 ft (5 meter). We also offer the cleanUV™ UV-C LED Strip Light product, which emits 270 nanometer UVC radiation. This product is sold in a 3.2 ft (1 meter) reel.
Further, you may want to consider our realUV flood light available in 365nm and 395nm - a fixture-style that can hang overhead.
Unfortunately, it does not appear that we offer products which meet the '280-315nm' and '250nm and below' requirements requested.
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 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!
LED Light Bulbs Rated for Enclosed Light Fixtures
I am wondering if you sell any light bulbs that are rated for an enclosed light fixture.
We're happy to confirm that our Ultra High 95 CRI A19 5W LED Filament Bulbs and our Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb products are compatible with enclosed light fixtures.
Do you have a Flicker-free Dimmable Bulb Compatible with an Enclosed Fixture?
I live in an apartment with enclosed fixtures and am trying to find High CRI dimmable flicker-free bulbs that will last a semi-reasonable time in an enclosed fixture.
Unfortunately, our dimmable LED bulbs are not compatible with enclosed lighting fixtures due to the requirements for heat dissipation and airflow.
However, if the lighting fixtures are not fully-enclosed, we would be happy to recommend our Full Spectrum E26 BR30 LED Bulbs. These products feature a high CRI and are dimmable. That being said, this product is not flicker-free.
What about the filament bulbs? I know it's not flicker-free (I have some of the BR30s from my old apartment already, but these are def fully enclosed)
Yes. We can confirm that A19 filament bulbs are suitable for use in enclosed fixtures and damp locations.
LED Bulbs for Art Studio with Track Lighting System Compatibility and E26 Base Standard
I'm trying to choose between 2 of your wonderful products to light my art studio. I have 2 rows of track lights with E26 Edison sockets. I'm not sure if I should get the regular bulb (NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio) or the floodlight version (NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio).
We can confirm that both our NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio bulbs are compatible with track lighting systems that utilize the standard E26 base.
Regarding the differences between the two products, the BR30 does offer a narrower beam angle than the A19 bulb. Other customers have let us know that this feature has been beneficial for their track lighting fixtures.
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:
I am a painter and cannot simply change the bulbs. Do I need to order bulbs and a different fixture, or just buy a full fixture from you?
I am a painter with a small (about 3.5 m by 1.5 m) space where I paint. It's a sunroom and has amazing natural light, but I have been struggling to paint at night. Due to uninteresting reasons, I cannot simply change the bulbs- and I am thus going to replace the entire fixture. Do you think it would make more sense to order bulbs and a different fixture or just buy a full fixture from you?
We may recommend utilizing our bulbs within another replacement lighting fixture, as the current fixtures we offer are not dimmable.
If your replacement fixture accepts BR30 bulbs, we would be happy to recommend using our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio. We recommend this product because it has dimming capability, offers a high CRI, and emits light that is similar to daylight.
This product has two color temperature options, 5000K and 6500K. 5000K will have a neutral daylight color point, while the 6500K has a color point similar to full daylight. You may find that one option is better suited for your space than the other.
Are E26 Light Bulbs Interchangeable?
I have a fixture that came with a 14 watt E26 standard Medium base CFL bulb. Can I replace these with dimmable LED bulbs?
Based on the description provided, we believe that the following bulbs may work in your fixture, as both are dimmable and have a power consumption under 14 watts.
1. Ultra High 95 CRI E26 A19 5W LED Filament Bulb for Home & Residential
2. Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential
Can I use an E26 BR30 bulb in a recessed ceiling fixture (no covering)?
Can these bulbs be used in a typical recessed ceiling fixture? There is no cover, so the bulbs will not be fully enclosed. I really want to change the lighting and feeling down here in the basement and I'm hoping these full-spectrum lights will help.
We can confirm that the BR30 E26 LED bulbs generally fit into recessed ceiling light fixtures, so long as the fixture is designed to accommodate the E26 base.
Please note that these lights do require airflow for proper heat dissipation. So long as these bulbs are not being covered by an enclosure, they should not experience overheating.
