Do you have LED lights that do not emit EMFs?

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 EMFs, do you have any recommendations 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

We would recommend our BR30 lamps, which we have linked below:

While we do not test for EMF, we do have very low flicker rates on these lamps (<6%) which may be of interest to you. Additionally, the 95 CRI rating will ensure that colors in your space will look natural and vibrant.

Home Lighting Design for Permanent Installation

I'm hoping to improve the lighting in my house because of our somewhat weak sunlight and short days. Are you aware of lighting designers in Washington State that are familiar with your products? I would like to install something more permanent/discrete here and would appreciate any recommendation you could offer.

Our LED strip lights sound like a great fit for your residential installation. Unfortunately, we do not have any specific lighting designers or contacts, but we would be more than happy to assist with any technical or product questions you may have.

We've linked below to our most popular LED strip light product for residential installations:

Additionally, below is a link to our configuration diagram, which may help in providing further information about the required components and other installation considerations:

Can I replace the traditional wafer lights with LED strips?

I am building a house with traditional wafer lights and I wanted to see if I can replace them with LED strips. For example, the living room is 15x17 feet and I have (12) 1100-lumen LED wafer lights. Can I replace them with 4 16' LED strips? How much output does the diffuser remove? In theory, the strips should output 28800 lumens vs 13200 for the recessed lights. I would want the strips to be equal to or greater than the wafer lights.

Based on the details provided, it sounds like our LED strip lights could be a great replacement for your LED wafer lights. Each reel of strip lights would require a dedicated power supply, such as our TRIAC Dimmable Power Supply for LED Strip, which may already be compatible with your wall dimmer. 

​The lights can be installed within our aluminum channels, which we can confirm will reduce transmission by roughly 10% if the diffusion covers are installed. Even so, the total lumen output should be far greater than the wafers currently provide. 

We have shared some LayoutMaps below which illustrate some common installation layouts and include links to the recommended products and accessories. Hopefully, the contents are helpful for your installation planning process.

Lighting from Home Office in Room with No Windows

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

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

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

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

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

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

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

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

UV LED Strip for Bedroom Lighting

I plan to have 8 feet of 365nm UV strip in each of the 4 corners of the 12 x 11-foot room. Could you advise me on what to order? 

As a primary step, it might be helpful to know that our realUV™ LED Strip Lights have a maximum combined length of 16.4 ft. Connections that are greater than 16.4 ft will result in a voltage drop and reduced output. As such, we typically recommend utilizing one dedicated power supply per full reel of realUV LED Strip Lights. 

It would appear that your installation would require two full reels, as well as two dedicated power supplies. If you would like to use wall dimmers, we would likely recommend the 12V TRIAC Dimmable Power Supply. 

In the hopes that it is useful for your installation planning, we have shared a LayoutMap diagram from our website below. This diagram features links to the connectors and power supplies that are most often recommended for installations similar to the one described. 

LayoutMaps™ - LED Strip Light Layout 7021_4C

That being said, please note that the realUV LED Strip Lights outputs light in the UV-A wavelength range, which is a weaker form of ultraviolet radiation that is found in natural daylight. As such, while there are fewer concerns than with other ultraviolet products that fall under the UV-B or UV-C wavelength ranges, we have some general safety guidelines that we would recommend following:

The ultraviolet emitters have a very high intensity when used at a very short distance, but less so at longer distances. Therefore, ensuring that people or animals do not come near the UV source can help reduce the risk of any eye safety issues. Ultraviolet energy is mostly invisible to the naked eye. It can be difficult for the vision system to recognize a high level of UV “brightness” and produce a natural response to squint or look away, in the way that natural white light would.

Do you think that I would be better off ordering 2 flood lights instead?

Generally speaking, while the realUV LED Flood Lights offer a more simple installation that requires fewer connections and power supplies, they are comparatively limited in their ability to be used with wall dimmers. 

​So long as your installation does not require fine-tuning of output or connection to wall dimmers or in-wall power supplies, you may find more benefit in using the realUV LED Flood Lights over the realUV LED Strip Lights. 

High CRI Bulbs for Outfitting House Lighting

I will need a whole bunch of good-quality bulbs. Rather than me poking through your online ordering system and hoping to pick the best options. Can you figure out suitable part numbers with a good 90+ CRI?

Based on our review, it appears that we have two products that directly match the details provided within the lighting table. We have attached links to each product below, in the hopes that it proves to be helpful.

While our A21 lightbulbs are 100W equivalent products that may also be of interest, please note that this standard has slightly larger dimensions than the more common A19 lightbulb. 

4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb 

4000K Full Spectrum E26 BR30 LED Bulb

4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulb

LED Strip Light Recommendation for Front Room Installation

I am looking to light my front room with an LED Light strip, preferably 1 power source for my front living room (79 feet total). The room has 10 feet high Barrel ceiling with a piece of trim 8’ up the wall. I wanted to run the strip around the entire room on top of the trim (5/8 inch thick) and use a diffuser strip, maybe V-shaped. There are eight 45-degree angles (the fireplace pops out 1’). Need dimmable, very bright (95+), and perhaps able to change color although the dimmable super bright white is most important. Would prefer to have it wired to a light switch on the wall and a remote to control the colors. Interested in the multicolor or just white?

Based on the details provided, it appears that the installation area would require five 16.4 ft reels of our LED Strip Light products. 

As a starting point, it might be helpful to know that our LED Strip Lights have maximum combined lengths of 16.4 ft for the 12V version, and 32.8 ft for the 24V version. As each foot of LED Strip Lights uses 5.5W, we generally recommend one dedicated power supply per full reel of product. 

For a multi-color installation, we recommend the FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, which can be combined with the DMX Dimmer and Decoder as well as a third-party DMX Controller for the adjustment of each color channel. 

If a single-color white LED Strip Light is preferable, we have many options that can be powered by the TRIAC Dimmable Power Supply and easily connected wall dimmers and smart home systems. For residential installations, we often recommend the 2700K or 3000K options of the CENTRIC HOME™ LED Strip Lights for Home & Residential. 

As can be noted in the LayoutMap below, multiple TRIAC Dimmable Power Supplies can be connected to the same dimmer so long as the maximum amperage is not exceeded. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

We will want the white only dimmable strips. As bright as we can get 24V. Looks like we will need 2 of them and will need 2 power sources. Ran into one dimmable strip. You didn’t mention the V-shaped track with a cover that disperses the light as not to see the individual LED lights. Do you carry those? If not, how wide are the LED strips?

We, unfortunately, do not have any V-shaped tracks, and we do sincerely apologize for any impact this may have on your installation planning. 

Currently, we have both the flat and corner version of the aluminum channels available, which are able to accommodate the 10mm width of our LED Strip Lights. That said, third-party manufacturers such as Klus Design appear to have many other form factor options available. 

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. 

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. 

LED Strip Light for Home/Residential Lighting

I have an old Victorian house and am thinking of installing LED light strips inside the picture rail. I prototyped this with the 2700k Centric Home strip + the FilmGrade Flicker-Free Dimmer and it works wonderfully though it's a bit yellow. 

Is there a difference between the 3000k Centric Home LED Strips and the 3200k FilmGrade White LED Strips other than the color temperature? 

As the underlying technology is identical, the only difference between the two items is the color temperatures available. Both items are also available in the same 12V and 24V options.

What is the difference between the TRIAC Dimmable Power Supply and the Centric Series Flicker-free Dimmable Power Supply? 

The TRIAC Dimmable Power Supply has an optional junction box, whereas the CENTRIC power supplies have slightly smaller dimensions. The smaller dimensions can be quite helpful for installations that have less room for wiring and power supplies, such as cabinetry installations. As a further note, the CENTRIC SERIES™ power supplies are only available in the 24V option, whereas the TRIAC Dimmable Power Supply for LED Strip is available in both 12V and 24V options.

For those power supplies, what are the mounting restrictions? I was thinking of putting them in the basement ceiling, but they would be running up against Radiant Barrier insulation that currently covers the bottom of the floor joists. 

As we are not familiar with the standard precautions that a radiant barrier installation might require, we would likely recommend reaching out to a local electrician for an informed opinion regarding safe placement. 

Do you recommend putting a fuse between the output of the power supply and the light-strip? If so, how would you calculate sizing? 

Generally speaking, adding fuses between the power supply and LED Strip Light products is not required or recommended. 

High CRI 6000K Daylight Bulb

I'm looking for a lightbulb that is a quiet, high CRI daylight bulb that just plugs into a normal household socket, and is 6000k. Do you have any recommendations for me? 

Unfortunately, we do not have any 6000K A19 lightbulbs currently available, and we do sincerely apologize for any impact this might have on your purchasing plans. 

If you would like to directly compare the two closest matches in our catalog, those being the 5600K FilmGrade™ Flicker-Free A19 LED Bulb and 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb, please feel free to take advantage of our 30-day return policy. 

Guidance on Light Type and Required Accessories for Residential Project Lighting

I would like to discuss a project we are working on for a customer and we would like to get some guidance on lighting type and required items to finish the project. 


1) 300 Linear feet of trimless recessed channel in plaster - 3 or 4 inches in size. 2) 80 Linear feet of trimless recessed channel in plaster - 2 inches in size (40 feet will be exterior wall mount).

Item# 1 Some of the area would require 2 LED strip lighting to be run in the same channel. Based on this we would need approximately 600 Linear Feet of LED strip lighting. 

For starters, it might be helpful to know that our LED Strip Light products are sold in 16.4 ft reels, and have maximum combined lengths defined by voltage (16.4 ft for 12V, 32.8 ft for 24V). As such, if any installation where lengths greater than the above is to be connected, they would require dedicated power supplies and connected wiring to the power source. 

If you require longer uninterrupted lengths for your installation, we unfortunately may not have the ideal products available. We do sincerely apologize for any impact this might have on your installation planning. 

​Further, while we currently sell the Aluminum Channels for mounting the LED Strip Light products on walls and other surfaces, we do not have plaster channels available in our catalog. 

I am attaching the plans with this email, we are planning on installing the linear lighting in the OPEN space; only rest of the rooms will have canned LED light. 

1. Family room / Kitchen - various lengths 4, 8 and 12 Foot runs

2. Great Room 4 of 16 Feet Linear light

3. Entertainment - 2 of 3 8 or 12 Feet Linear light

4. Pooja Room - 2 of 12 Feet Linear light

5. Dining Room - 2 of 12 Feet Linear light

6 Walkway Top and Bottom - 4 Feet Runs


Garage Pillars - 3 - 6 or 8 Foot 

Main Door 2 of 8 Feet runs

Though we are more than happy to recommend some products for your construction, we might recommend reaching out to a lighting designer for layout advice, as we do not specialize in planning layouts or lighting installations. 

In the hopes that it proves to be helpful, however, we have attached links to some of our LayoutMaps below, which illustrate installations where segments of LED Strip Lights are powered by multiple power supplies while connected to in-wall dimmers. These pages also list the connection accessories that are recommended, which we hope are helpful for your planning purposes. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

LayoutMaps™ - LED Strip Light Layout 3001-1B

For residential installations, we typically recommend utilizing the 2700K and 3000K color temperatures as can be noted within the guide below. As such, we would recommend the CENTRIC HOME™ LED Strip Lights for Home & Residential product, which is available in those color points in both 12V and 24V versions. 

Which LED Light Color Temperature Should I Choose?

For a list of in-wall dimmers and smart home dimmers that are compatible with our power supplies, such as the TRIAC Dimmable Power Supply, please review the following link. 

Updated Dimmer Compatibility 2021 

What is the difference between GE Reveal and your products?

I just bought a new house and will be upgrading the lights there. I'm a big GE bulb fan but recently ran into your site. Can you explain the difference between what more you provide vs GE reveal and refreshing series of lights?

By our review of the GE Reveal and Refresh lights, they appear to vary in size and features, though the voltage requirements and lumen output of these items appear to be comparable to our standard A19 lightbulbs. That being said, it appears that some of these GE products are dimmable, whereas only our filament A19 bulbs and BR30 bulbs are compatible with dimmers. 

Further, it appears that our LED lights can offer a higher CRI of 95+, whereas the GE products provide a CRI of 90. The higher CRI can be very beneficial for installations such as artwork studios, galleries, and video capture where robust color-accurate illumination is required. 

As our products are designed to be human-centric, they are created to provide full-spectrum, high-quality output that provides a high CRI to combat eye fatigue while ensuring color accuracy. Unfortunately, we have not been able to locate the full photometric reports for the GE products, which we would like to use to provide you with a comparison of the spectrum output. 

In lieu of that, we have attached a link to our full set of photometric test reports for our full spectrum lights in the hope that it proves to be useful for your product comparison. 

Can you also tell me how your light bulbs compare to the product below? It appears to have a higher CRI and R9 value.

The GE Sun-Filled LED product appears to be a new product with what appears to be an improved spectrum intended to better approximate natural daylight. In this regard, the color performance appears similar to our A19 and BR30 products (both of our products achieve 95 CRI and 80+ R9).

Unfortunately, the GE Lighting website does not provide additional information about the extended CRI values, chromaticity, or flicker performance, so we are unable to make any definitive comparisons beyond the general CRI values that their website indicates.

We appreciate your inquiry and will definitely see if we can find more information or even perform internal testing on the GE Sun-Filled product soon!

We would perhaps recommend purchasing both products to test and compare as we can offer a 30-day free return window for all of our products. (Hopefully, GE Lighting's authorized retailers offer a similar returns program, allowing you to perform these tests).

LED Lighting Recommendation for Winter-time Mood

Which of your products do you recommend for lifting people's mood during the winter time? I would guess it's one of your "Centric Daylight" products. Which color temperature is most popular for this use? 

For human-centric lighting, the most important qualities to consider are flicker-free operation, full-spectrum output, and a high CRI. These features in conjunction create lighting environments that cause less eye fatigue while providing a superior quality of illumination. 

To find which color temperatures are right for your installation, we would recommend reviewing this link. If your installation is residential, we would likely recommend the 2700K or 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb, as those are the most common color points for homes. This product, as is true with any color temperatures available in our A19 products, will feature the aforementioned high-quality output. 

Ceiling Bulbs Replacement with Daylight Color

I need more daylight! I want to replace the bulbs in my ceiling lights with 90+ LEDs at the most daylight color possible so I don’t slit my wrists. Can you recommend the best bulbs?

For recessed ceiling lighting, we often recommend our BR30 products, which feature a high CRI and full spectrum output, which will hopefully help with the cloudy northwest seasons. Based on the details provided, we would likely recommend the 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential, as this is one of the most common color temperatures for residential spaces. 

That being said, if you would like to order our cooler color temperatures (such as 4000K, 5000K, and 6500K) to compare in your new home, please feel free to take advantage of our 30-day return policy. 

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. 

High CRI Bulb for Home Lighting

I am shopping for some high CRI lights for use in my home and had some general questions. 

Is there any way to get the bulbs in 3000K that don't have the issue? 

While I can confirm that the recent batch of the 3000K bulbs has a slight green tint, the color output remains within our color quality specifications. These filament bulbs typically require ~15 minutes or so for the color tint to stabilize, after which the color tint adjusts to being neutral. 

Unfortunately, for our most discerning customers, this greener tint may be bothersome and may not meet expectations. If you receive any products from our website that do not meet your expectations, please feel free to take advantage of our 30-day return policy. 

Will your company be making a higher-wattage version of this bulb in the future? 

As far as I am aware, there are no plans to release a higher-wattage version of the filament bulb products. That said, I would be happy to share your interest in such a product with my development team for future consideration. 

Does your company have any resources or recommendations for lighting design ideas or projects? I am wanting to use strip lights and other types around the house, but I'm looking for some inspiration and ideas. 

For installation inspiration, you might find value in the product reviews posted on our LED Strip Light product pages, where our customers have shared photos and descriptions of their installations. For example, several installation photos can be found on the CENTRIC HOME™ LED Strip Lights for Home & Residential page.

I am interested in doing a horticultural lighting project. I am looking for LEDs that match the sun's natural spectrum but it is hard to find information on this online. 

Does your company have any diodes that are still good but not matching the quality that you can sell? Basically second-tier absolute series. Also if I was to find a source for chips that have the broadest spectrum, does your company have the ability to manufacture strips from the led chips for a reasonable price? 

While we do not sell individual LED components and are unable to accommodate custom product fabrication, you might alternatively be interested in our 6500K FilmGrade™ WHITE LED Strip Lights or 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail, which are both able to offer a high CRI of 95+, which is just slightly lower than the 99 CRI offered by the Absolute Series. 

Pure White LED Bulb for Residential Lighting

I found that most residential LED bulbs look somewhat orange in color. Especially at night. I find them hard to read. I want a pure white bulb but find them difficult to attain. What do you recommend, please? I would also like a high-wattage bulb 150-watt equivalent.

For a neutral white color temperature, we usually recommend the 4000K option. If it proves to be helpful, we have attached a color temperature guide from our website below. 

Which LED Light Color Temperature Should I Choose?

While we do not have a 150W equivalent currently available, you may alternatively be interested in our new 100W-equivalent 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulb. 

Can you please explain what 4000K, 5000K, and 6500K means? I appreciate your willingness to help me understand LED technology, which is somewhat difficult to understand.

Generally speaking, color temperatures (4000K, 5000K, 6500K) are measurements for the color of light being produced by a light source, measured in degrees Kelvin. 

​For example, the ‘warm orange’ tones that you referenced earlier were likely the output of ‘warm' color temperature lightbulbs, such as 2700K or 3000K. These warmer color temperatures are usually recommended for homes and residential properties.

Comparatively, the 'cool white' lights that you have likely seen in factories, large stores such as Costco, or hospitals are usually 5000K or 6500K. Offices usually use the more 'neutral' 4000K color temperature. 

In the hopes that it proves to be helpful, we have attached an image from a blog post on our website below, which displays the visible difference that the most common color temperatures would have on the same kitchen installation. As you can tell from the image, the higher degrees Kelvin, the cooler the light output becomes.

Choosing Proper Lights for Home Reno Project

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

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

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

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

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

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

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

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

LayoutMaps™ - LED Strip Light Layout 3001-1C

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

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

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

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

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

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

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

2700K vs. 3000K: Which is recommended for home and residential applications?

What’s the biggest seller between the 2700 & 3000? Do most prefer to use 2700 in bedrooms & living room, & 3000 in bathrooms, kitchen & laundry room? Is the 95 CRI best? Can they be used in enclosed ceiling fixtures? Running low on my old GE Reveal incandescent bulbs, plus would like to save on electricity. 

We have shared a blog post link below that compares the 2700K and 3000K color temperatures for home installations, which we hope proves to be helpful. 

​As CRI is a measurement comparing the quality of light output to that of natural sunlight on a scale from 0-100, we can confirm that the 95 CRI offered by our products will result in a very high quality of light output. 

Further, as the LED light bulbs contain internal circuitry which benefits from a moderate amount of airflow for heat dissipation, we do not recommend utilizing them in enclosed fixtures. 

Choosing Between 2700K and 3000K

Are y’all working on the development of your bulbs that can be used in enclosed fixtures like in my kitchen, hallways, laundry room & closets? Right now I can only use these for a bathroom vanity, a pendant light & lamps. Which is your bestseller for residential? The 2700 or 3000?

What do you recommend for use in enclosed fixtures to avoid flicker? Incandescent or halogen rather than LED that can be used in enclosed fixtures?

We are happy to confirm that we look forward to improving our flicker-free products to allow for enclosed fixture installation down the road, though we do not have an expected availability date for such a product at this time. 

We can also confirm that as many of our LED lights contain hardware and wiring that traditional halogen and incandescent bulbs do not utilize, they can malfunction when the heat being generated is not able to dissipate via a moderate amount of airflow. 

Our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential might be a great option as they can be installed within enclosed fixtures without the need for airflow.​

Our customers tend to prefer 2700K for living areas such as bedrooms, where the 3000K temperature is more commonly installed within kitchens and bathrooms. Unfortunately, we do not have any sales data on hand regarding which option is most popular overall. 

​That said, please feel free to take advantage of our 30-day return policy if you would like to order both options to make direct product comparisons.

3000K vs. 4000K BR30 Bulbs for Home and Residential Lighting

I need to purchase BR30 bulbs for my new construction home build and I am having great difficulty deciding between 3000k and 4000k on the color spectrum. I actually fear that 3k will be too yellow and 4k may be too white. 

We have attached an article below which contains tips for making an informed color temperature selection for each type of installation area. 

In short, we generally recommend 2700K for living areas and 3000K for kitchens and dining areas. The 4000K on the other hand, is usually recommended for retail areas and office spaces. 

Which LED Light Color Temperature Should I Choose?

High CRI 90+ Replacement Lights for Indoor Installation

My decorator wants me to replace my bulbs with CRI 90 or higher to improve the natural color of the room. I'm new to these bulbs and would appreciate your assistance. These are for indoor lights. 

As you consider the options in our catalog in the interim, it might be helpful to know that our products offer a CRI of 95+, which means that the quality of light output is extremely similar to full noon daylight. We have also attached a few instructional resources from our website below, which we hope prove to be useful for your purchase planning.

Which LED Light Color Temperature Should I Choose?

Home & Residential Lighting

High CRI LED Lighting

The lights I will be replacing will be in the bathroom, bedroom, and one in the kitchen above the sink. The bulbs that are in now make the walls look pink instead of light gray. I have four bulbs over the counter in the bathroom. I’m hoping to have not just better color, but good light for makeup application. The bedroom had an overhead with two bulbs.

I have two flush mounts in the kitchen and the dining room that have this piece with a bunch of little Led lights. The hallway has the same thing. I have never seen this before, so have no idea if it can be changed to just regular bulbs. I would like the bathroom and kitchen to be bright, the bedroom a little softer.

Though we, unfortunately, do not have replacements for the embedded LED light fixtures within the dining room and hallway fixtures, we do have A19 products that appear to be compatible with the bathroom, bedroom, and kitchen light fixtures.

As referenced within the previously provided article, we generally recommend utilizing 2700K for living areas such as bedrooms and hallways. For kitchen spaces and dining areas, we would instead recommend utilizing 3000K lights. 

As such, I recommend our 2700K and 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs for those spaces. That said, please note that these A19 lights are not compatible with dimmers. If you have space that might benefit from in-wall dimmers, we would then recommend the Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential light (though please be advised that this item is out of stock until August 16th). 

These products can offer not only full-spectrum light output, but also feature a high CRI of 95+. As CRI is a measurement for how similar the quality of light is to full daylight on a scale from 0-100, I believe that these lights would benefit each room with much improved high-quality output. 

LED Strip Light for Master Closet Shelving

I would like some assistance understanding which tape to use for our condo project's master closet lighting. My concern is the lighting being too bright with the number of shelves I'd like to illuminate. I can understand wanting to keep product inquiries to a minimum, but I'm getting ready to order the first (3) of (29) units, and would greatly appreciate some assistance in selecting the correct product. 

The first point of advice to comes to mind would be to reference our Lumen Estimation Calculator. By inputting the dimensions of the space as well as the purpose for the space (such as manufacturing, artwork creation, or living areas), the tool will provide a recommended quantity of products, as well as the recommended lumens for optimal illumination.

Further, it might also be helpful to know that LED strip lights can be paired with in-wall dimmers (as well as smart lighting systems) and dimmable power supplies. The combination of these products will allow for the output to be easily adjusted, which could be useful in ensuring that the master closet light output can be set to the preferred level of illumination.

We have also provided two layout diagrams below, which I hope prove to be helpful for your installation planning. These interactive diagrams contain configuration instructions as well as links to the recommended connector accessories.

Does your A19 5W LED Filament Bulb have low flicker?

I noticed this bulb, unlike the rest, doesn't mention that it is low-flicker: Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential 4002.27 Is this, too, an equally low-flicker bulb?

We can confirm that the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential product is not flicker-free as our other A19 bulbs are, and has a flicker rate of 29%.

For future reference, the flicker rates of our products can be found within the photometric reports on the respective pages. I have attached a link to this product’s photometric report below, for your review.

Ultra-High 95 CRI A19 5W LED Filament Bulb for Home & Residential Photometric Report

If the flicker-free functionality is preferred for the installation, then we would alternatively recommend any of our other A19 LED bulbs such as the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb​ which is available in the same color temperatures as the filament-style bulb referenced. 

Full-Spectrum LED Bulbs for Residential Lighting

We are looking to replace our std LED with full spectrum and have some questions regarding the correct ones to use. They will have the E26 base but would like some guidance on the other features. 

We can recommend our CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs, which are full-spectrum, use the E26 base, and are available in the most common residential color temperatures of 2700K and 3000K.

Alternatively, you may also be interested in our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which is a filament-style LED bulb that uses the E26 base, and is also able to offer full-spectrum light output. 

LED Bulbs Recommendation for Home Lighting

I'm looking to replace the existing light bulbs in the home we’re moving into. They’re A19. Can you help me understand the differences between the following: Centric Home Full Spectrum flicker-free, Centric Daylight Full Spectrum flicker-free, and FilmGrade flicker free

The applications are bedrooms, bathrooms, offices, and some common areas like a hallway, and laundry room. Some of the bulbs will go within a light fixture that has yellow glass. 

What am I looking for? Flicker-free, good-quality light. 2700K and 6500K seem too far on the color spectrum. Probably 3000K to 4000K is what we’re looking for.

Generally speaking, we find that living spaces generally benefit from 2700-3000K color temperatures, where office spaces benefit from 4000K. However, I have provided a few links below which might assist in selecting the right color temperature for each of the spaces referenced.

Which LED Light Color Temperature Should I Choose?

Guide to 2700K vs 3000K:

Guide to 4000K:

Further, as the A19 products referenced (Centric Home Full Spectrum flicker-free, Centric Daylight Full Spectrum flicker-free, FilmGrade flicker-free) are of the same family line, the primary difference will be found in the available color temperatures. As such, each offers the same high CRI and will be able to provide identical performance.

​Finally, please note that our A19 bulbs will require a moderate amount of airflow for heat dissipation. As such, we advise against use within completely enclosed fixtures, as this may cause higher than normal failure rates.

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:

LED Strip Lighting for Soffit and Kitchen Overhead Installation

I'm installing LED strips in a couple of locations and hoping you can help me select them. Can you recommend the right power supply and controller? 

1) In a soffit pointing down running along both walls in the living room (30 ft per wall) 

2)Installed overhead in the kitchen in a recessed channel instead of overhead halogen downlights. 

Our CENTRIC HOME 3000K LED strip lights sound like a great fit for the installation.

​The easiest way to test this set up would likely be a set of the following:

1) CENTRIC HOME 24V 3000K LED Strip Light

2) TRIAC dimmable 24V power supply

​Below is an installation diagram showing how this should be wired to a wall dimmer. (The setup could of course be tested without a dimmer and wired directly to a branch circuit).

Both components can of course be used in the final installation as well.

LED Strip Design for Home Security System

I am looking to redesign how home security lighting is done and add just purely aesthetic characteristics to a previously fairly unattractive security feature for the home. The short description is that I want to create windows that have motion sensor LED strips around the edges of them that could be bright enough to, for example, light up a potential intruder if they pass the window or sliding door. 

What are the options for how many lights/meter that you would recommend for something like that? And what about watts/power/lumens? Can a strip be manufactured in 90-degree angles so that it is a single strip that basically forms a picture frame?

While your LED strip application in security systems sounds very exciting, the scope of our ability to provide support for specific use cases such as this quite limited and I do apologize in advance.

As a general starting point, we would perhaps recommend using our lumen estimation calculator to determine how many lumens (and therefore feet/meters) of LED strip lights would be needed for sufficient illumination. I am no expert in security systems, but I would imagine most cameras have relatively good image quality in low-light environments as well, so perhaps the total brightness needs would be quite low, in line with a standard residential installation.

​I've linked to the lumen estimation calculator below:

​As far as motion sensors and the connectivity of it all, we would recommend researching third-party solutions as our product offerings are limited to the LED strip light and basic power supply units (without such features). 

Recommended Installation for UV Reactive Tapestry

I have a room that is roughly 130 square feet. There are 3 walls and where the 4th wall normally would be is just a transfer into my kitchen. I have a UV reactive tapestry on all sides of the room besides obviously the entrance to the kitchen where there is no wall. What setup would you recommend to effectively light all of my tapestries with good UV light? Also, would you suggest 356nm over 396nm in this situation? 

For an installation that would benefit from the most UV effect, we would recommend the 365nm version of our ultraviolet products.

Though the realUV™ LED Flood Light product is easy to install, it can take up more room than the alternative, which may not be ideal for all installations. Generally speaking, one 365nm floodlight should illuminate an area that is roughly 10x10 ft with 8.0W of UV output.

Alternatively, the realUV™ LED Strip Lights can be installed in many different ways, though it will require a dedicated power supply. Based on my estimates, I believe that one full 16.4 ft reel should be more than enough for the dimensions, as it outputs .75W of UV output per foot.

I have attached a few links below for our realUV LED Strip Light LayoutMaps, which provide detailed installation instructions, as well as links to the recommended accessories.

Waveform Lighting LayoutMaps™:

LayoutMaps™ - LED Strip Light Layout 7021_4A

LayoutMaps™ - LED Strip Light Layout 7021_4B

LayoutMaps™ - LED Strip Light Layout 7021_4D

If I used the flood light would I have to place the light in the center of the room on the ceiling? or could I put it on a wall facing the room to illuminate my art in a 10x10 room

We're happy to confirm that the floodlight should be easily installable in either method, thanks in part to the adjustable bracket.

It might also be helpful to know that the irradiance pattern will have the most concentrated output directly in front of the light. As such, you may decide to position the light such that the most important artwork is best illuminated.

LED Strip Lighting Accessories and Installation Layout

My wife and I plan to build a new home. The house includes a cathedral ceiling area 32 feet wide and 20 feet deep. We plan to illuminate the gambrel arch cathedral ceiling using Centric Home 24V DC 3000K LED Strips. Since the 20 feet is longer than the 16 feet of your strips, we plan to use two each 10 feet strips with separate power supplies for each strip and two dimmers, one for each side of the room. We want to use corner aluminum channels so the light is aimed at 45 degrees with respect to the horizontal. May I please speak with someone about the list of components I should make sure to have on my order? 

As you mention correctly, the 20 foot span is unfortunately too long for a single power supply, so I agree that the approach to "split" this into two sections of 10 feet, each with its own power supply, would be the best approach.

​Furthermore, the "corner" aluminum channels should provide you with exactly the type of 45 degree light angle and should work very well for you.

​Below are the list of items needed for this installation:

​2x PN 3004.30

2x PN 3094.096

2x PN 3061

​You may also find our configuration diagram helpful in thinking about the layout and wiring:

​We do also agree that the LED strip lights would be the optimal choice here. While traditional lamp form factors such as spots and floods are convenient and familiar, for a new home installation, the LED strip approach will provide for the "latest and greatest" in terms of efficiency and versatility.

From the side of the room where I would mount the LED strips to the apex of the ceiling is a straight line distance of 22.4 feet. Now, we would mount LED strips on both sides of the room, so there would be two strips- one on each side of the room- aiming at the apex of the ceiling. Still, given the 22.4 feet distance, will there be enough light reaching the apex to illuminate it? I do not need a "bright" illumination, but I want to avoid any dark areas on the ceiling. How do I determine what the ceiling illumination will look like?

We unfortunately do not have a good answer for you here, as the light spread would depend on the exact layout and would require complex computer simulations to provide any accurate recommendations.

​The 22.4 ft distance is quite far, and while I do not believe it will be completely dark, it may appear dark when compared to the ceiling areas closer to the LED strips.

If you have the ability to locate the LED strips closer to the center (such that they are situated closer to the point beneath the ceiling apex) that may mitigate some of the concerns you have.

It might also be helpful to know that the LED strip lights emit light at a 120 degree angle, with the most intensity at the center of that beam. This may give you an additional data point in determining to what extent the light spread would be affected by the angle of the pitched ceiling.

Suggested Color Temperature for Residential Lighting

Is there a big difference between ordering the bulbs from you all and buying bulbs from Home Depot or Lowes? 

Also, Can you tell me what kelvin temp I would need for (recessed lighting in the kitchen, living room ceiling fan, entryway chandelier, and bedrooms)?

While there are many great LED products available on the market, our products have been designed to offer a higher CRI and better color consistency than much of what you will find available at Lowes or Home Depot.

The CRI listed within our product pages represents how similar the light is in quality to that of natural sunlight. While some LED products offer a CRI of 80, products such as our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb offers flicker-free functionality and a CRI of 95+.

For living rooms and bedrooms, we generally recommend the 2700K option, whereas, for kitchens and dining areas, we would alternatively recommend the 3000K option. For recessed lighting, you might be interested in our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential products.

For more information regarding the right options for each space, I have provided a helpful blog post from our website below which might prove to be useful for your planning purposes.

Which LED Light Color Temperature Should I Choose?:

Household Bulbs for House Plants

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

Based on the details provided, there are a few different products that we might recommend depending on the preferred color temperature output.

For starters, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb product. Though these are not dimmable, they offer flicker-free performance and a high CRI. Further, the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products could look quite nice on a shelf display among plants.

We have attached a blog post link below from our website regarding color temperature selection, which might be helpful for your planning purposes.

Which LED Light Color Temperature Should I Choose?:

As our A19 bulbs will offer a very similar quality of light output, the right option might be better defined by the purpose of the space. For example, while we might recommend a 4000K option for a home office space, we would alternatively suggest a 3200K for a reading area.

I read the blog but didn't see anything about plants. Maybe I should rephrase my question. Which of your A19 bulbs has the correct spectrum and other properties to grow healthy houseplants? These plants are typical tropical varieties composed of mostly foliage, not flowering. Most prefer bright to medium indirect light. Some small 6" ish pots on a tabletop and some large floor plants. I just want to use a variety of attractive lamps that accept regular bulbs.

Though our High CRI A19 bulbs have not been specifically designed for horticulture as some of our other products have been (such as the PhotonTube™ T5HO LED Grow Light Tube for Horticulture product), I am happy to confirm that they offer an extremely similar full spectrum light output to those of our horticulture-focused products.

Regarding the right color temperature for your installation, you might find benefit in either the 4000K or 6500K options of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

While the 4000K provides an output that simulates late-season light, the 6500K option will offer light that is very similar to natural daylight and simulates the light which occurs in early-season growth periods. For an in-depth analysis of the technical benefits that our full spectrum lighting has on plant growth, we have attached a terrific blog post from our website below.

LED Linear Lighting for Bright Reading

I am 99 and my wife is 89. Our eyesight is not like it was. I find that task lighting is not good. We have a high ceiling den with a soft and decorative light string. Thinking linear LED in the soffit to project on the tray ceiling would provide good defused bright reading. 

If you could determine what color temperature you were interested in for your installation, we would be more than happy to provide a few product recommendations.

If a guide for color temperatures proves to be useful, we have provided a link to a blog post from our website below.

Which LED Light Color Temperature Should I Choose?:

For more information on getting started with the LED Strip Lights products, I have attached a second blog post from our website below.

Lighting Recommendation for Dark Apartment

I am in desperate need of lighting advice for a small, dark apartment with only one window light source per room - one in the bedroom and one in the living room. I intend to replace all light bulbs with as bright a light source as possible - including in floor & table lamps. I suffer from SAD and want to simulate as much natural light as possible. With having to be cooped up so much of the time due to the pandemic, this need has become critical. I don't know how to determine wattage but am willing to go for the brightest. 

Based on the details provided, we might recommend either the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs, or the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs.

As these products are extremely similar, and offer the same 95 CRI light quality and wattage, the primary difference can be found in the color temperatures available.

For selecting the right color temperature for your spaces, the below blog post from our website might prove to be useful: Which LED Light Color Temperature Should I Choose?

Full Spectrum and Flicker-free LED Strips for a Dark One-Bedroom Apartment

I want to put hidden lights all around the ceiling of a dark one-bedroom apartment. I like a full-spectrum LED. Please help me understand and choose the right product. 

We believe that a great first step would be utilizing our standard bulbs in the lighting fixtures in your space.

Based on the details that you provided, we believe that replacing the existing light bulbs could make a large difference at a significantly lower cost than the LED strip light products. As such, we have provided some product links below.

Due to the stated preference for lighting which is similar to direct sunlight, we recommend the 5600K color temperature option of the FilmGrade™ Flicker-Free A19 LED Bulb. 

​This product can be easily installed into standard lighting fixtures, has a 3-year warranty, and offers full spectrum lighting that will appear visually identical to that of natural sunlight.

T5 Linear Light Fixture to Replicate Sunlight for an Apartment Space

I have recently moved into an apartment that has plenty of daylight but no direct sunlight. I wonder if the NorthLux 95 linear strips, placed along the floor molding behind my couch and beaming upward would replicate sunlight? 

Based on the details provided, it sounds like the NorthLux™ 95 CRI T5 LED Linear Light Fixtures could be a great way to illuminate your space!

These products are very easy to install, require no additional accessories or power supplies, and are well-suited for washing a wall in light. Further, multiple units of this product can be daisy-chained together for convenient powering.

Dimmable Power Supply Compatible with Centric Home LED Strip Lights

I'm building a light fixture for my dining room, which is roughly 10' x 10' x 15' high (it's an open space). I've calculated that I need 1,673 lumens and that 3' of your CENTRIC HOME™ LED Strip Lights for Home & Residential will provide that. What dimmable power supply do I need (assuming I use a Lutron or Leviton wall dimmer)? 

You are correct that the 3-foot section will provide approximately 1650 lumens, which should be sufficient for your needs. Do keep in mind, however, that depending on the design of your fixture, you may want a bit more brightness depending on the orientation of the LED strip lights as well as the fixture.

​As far as connecting the LED strip lights to a dimmer switch, you will want to use our TRIAC dimmable power supply product. we've included the product link below for your reference.


Additionally, our layout map for the product may be helpful in understanding how the product can be wired to your dimmer circuit:

Can you specify one or two specific Leviton or Lutron wall dimmer switches that are compatible with my order? 

We've tested a wide range of Lutron and Leviton wall dimmers for compatibility. Some of the most popular include the Lutron DVCL-153 series, which we have linked to below:

For further reference, you may want to review our list of tested dimmers, which can be found below:

RGB LED Strip Light Solutions for Residential Lighting

I am interested in your RGB strip lighting solutions for a new home I am building. If I understand correctly, your 24V ColorSpace RGB may be a good solution for me. However I am a bit confused about a few aspects: This light strip only does one color at a time, correct? And if I connect multiple light strips together, they will all show the same color at the same time, correct? Can the strip also produce white light? If so, at what Kelvin and CRI? How many lumens/feet does this strip produce in various colors? Besides the power supply, what accessories are required for this strip light? Is a DMX controller required to control the color settings? I could not find the associated accessories on your website. Can you please show them to me?

First off, our RGB LED strips are not individually addressable. This means that the entire strip will emit one color at a time.

​Secondly, the LED strip is capable of emitting white light, but the color rendering and color temperature value precision would be inferior to a standard white LED. We would perhaps recommend our 5-in-1 LED strip as an alternative:

​The 5-in-1 LED strip light emits approximately 180 lumens per color (warm white / daylight) and has a 95 CRI rating, in addition to full RGB control. The product can be used with a DMX controller or a third-party 5-channel controller such as the one linked below:


Each 16.4 ft reel should be connected to an individual power supply. The power supply is linked below:

BR30 LED Bulbs for Residential Installations

I am very impressed with your products and I'm looking to see if buying from you would be a viable option. We are renovating our whole house and need lights for every room. We have 4" and 5" recessed lights. The kitchen, dining, and master bed and bath have 15 ft ceilings. 

Our BR30 lamps sound like a great option. The BR30 lamps have a 3.75" diameter, so they should be a nice fit for both the 4" and 5" ceiling fixtures that you have.

​We would also recommend installing enough bulbs to achieve sufficient brightness levels for your space. You may find our lumen estimation calculator helpful in determining the lumen needs:


​Finally, in choosing color temperature, the 3000K is the most popular and recommended option for residential installations. Higher color temperatures (4000K and above) can be useful for art and photo studios where daylight calibrated light is useful.

​Please see below for the 3000K product link:

LED Lights with Motion Sensor Integration for Staircase Lighting

I'm looking for help with the product and layout (motion sensor at the top and bottom). I would like to run up one side, cross over (remodeling staircase) up the other handrail, and snake thru the wall to the adjacent room with the power supply. 

We currently do not have any motion-activated products, but we do offer a range of 95 CRI LED strip lights that should be a great fit for your staircase installation. Please see below for the product link:

Additionally, we have some configuration illustrations which may help determine which components should be installed. I suspect that our Layout Map 3001-1B may be a close match to the installation you have in mind. Please see below for the link:

LED Light Bulbs Equivalent to Natural Sun/Daylight

Could you please recommend which bulbs should I purchase to have bright sun/day light? My apartment is very dark, and the buildings around block natural sunlight. I need to have the light turned on during the day and would like to have an equivalent of natural sun/daylight. 

Please see below for our CENTRIC DAYLIGHT A19 LED bulb. These lamps can be used in any standard screw-in lamp socket and will provide you with bright daylight color for your space.

We would also recommend using our lumen estimation calculator to determine how much light you will need to ensure proper brightness:

Do you have bulbs that have no blue light or flickering?

I am in the process of designing a new home. My goal is to keep blue light and flickering as close to 0 as possible. Do you have bulbs that would satisfy this request?

In the interim, the first product that comes to mind is our 2700K CENTRIC HOME™ LED Strip Lights for Home & Residential product, which is flicker-free when paired with one of our flicker-free power supplies.

Alternatively, we also offer the Lux24™ Circadian LED Bulb product which might be of interest, however, this product is unfortunately not flicker-free.

If it proves to be useful, we also have a great article on our website that discussed blue light in depth:

Blue Light, Melatonin, and Circadian Rhythms:

I am designing a home from scratch and would like to have lights that have no blue light or flickering throughout the home. 

As mentioned in the blog post, blue light can be found within most light sources, including full-spectrum lighting. However, special bulbs such as our Lux24™ Circadian LED Bulb are designed to include as little blue light as possible. Unfortunately, this product is not designed to be flicker-free.

While we are proud to offer many full spectrum lighting products that are designed to be flicker-free, the Lux24 is unique in the extremely low level of blue light emitted. As such, we may not be able to provide any other products that could be ideal for your home design, as well as the specifications mentioned.

LED Strip Lights for Living Room Installation

I'm trying to buy "CENTRIC HOME™ LED Strip Lights for Home & Residential". I'm planning to use "Aluminum Channel for LED Flex Strip - 5 PACK" Can this be set up by someone like me? And what other products do I need to purchase?

The CENTRIC HOME™ LED Strip Lights for Home & Residential product is available in both 12V and 24V. As such, it will be important to select a compatible 12V or 24V power supply, such as our FilmGrade™ DC Power Supply for LED Strip.

​It might also be valuable to know that the LED strip lights have a maximum combined length that can be powered, which varies depending on the voltage selected. For the 12V product, the maximum combined length is 16.4 ft (5 meters). For the 24V product, the maximum combined length is 32.8 ft (10 meters).

If you would like to dim the lights, you can utilize the FilmGrade™ Flicker-Free LED Dimmer product, which can be connected between the LED strip lights and the power supply.

To connect the LED strip light segments, you can combine both the Female DC Barrel Jack Plug Adapter as well as the LED Strip to the Wire product.

I have attached a link below that illustrates the configuration I have described in greater detail:

Flicker Characteristics of A19 LED Filament Bulb

I am interested in the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. I would prefer using one of your flicker-free bulbs but they cannot be dimmed. What are the flicker characteristics of this bulb? 

Our A19 filament bulbs have a measured flicker of approximately 20% at 120 Hz. This is in line with incandescent bulbs. (Our photometric reports are here). Unless you have special circumstances that require an even lower level of flicker, we do not believe that the level of flicker exhibited by this bulb would be problematic for most residential applications.

​We completely understand the need for simultaneously achieving dimmability and flicker-free output, and do hope we are able to address this market need in the near future!

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. ​

Full Spectrum BR30 Bulbs for SAD and Home Lighting

I am looking to replace our whole home can lights with full spectrum bulbs to combat SAD and boost the health of my family. We live in Oregon and have limited sunlight exposure. I am trying to decide between your Ultra High 95 CRI E26 BR30 LED Bulb in 3,000K and your Full Spectrum E26 BR30 LED Bulb in 4,000K. Are they both suitable for whole-home use? Are they both full spectrum and beneficial for light therapy/heliotherapy? 

Since both items come from the same product family, which can be noted by the shared part numbers, the full spectrum features and performance will be identical across the two items. As such, both products would be suitable for home use. The only differentiator between the two can be found in the color temperature options available.

Generally speaking, the intended purposes of different spaces or rooms can help to define the proper color temperature selection. For example, general-purpose areas might benefit from the warmer 3000K color point, whereas kitchens and work spaces might benefit from the slightly cooler 4000K option.

Our website features some excellent blog posts which I have linked to below, which could prove to be useful in your selection:

Everything You Need to Know About Full Spectrum Lighting:

We are also happy to offer a 30-day return policy if the selected items don’t work well for the space. Simply let us know which items you would like to return, and we will issue a free return label. 

Could you clarify, if the effectiveness of light therapy is the same between 3,000K and 4,000K? Or is one more effective than the other? After reading this blog post, I see “light therapy” is listed for 4,000K but not for 3,000 K. 

While both color temperature options of this product feature the same high CRI and therefore would share extremely similar health benefits, the 3000K color temperature would likely be more beneficial than the 4000K.

We have two great articles on our website that go into further detail regarding the health benefits of certain color temperatures, which could be valuable in your decision-making process.

Recommended LED Light for SAD in a Basement Apartment Installation

I would like to get something for the basement apartment that is best for mental health during the dark winter in VT. I'm sorry, but I'm finding your website totally overwhelming with all the information. Could you just recommend something? Also, I was looking at the Centric series LED bulbs, but the two I saw said they were only 10W each. That seems really dim, especially for a dark basement apartment. 

Based on the details that were provided, there are a few products that we might recommend depending on the intended use of the space.

For use within general-purpose areas of the apartment, we might recommend the 3000K FilmGrade™ Flicker-Free A19 LED Bulb or the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

For work areas, or artwork creation areas, we might recommend the 5000K option of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

Each of these product options will offer the same high CRI, which measures how similar the light spectrum output of the bulbs is to natural sunlight. These products also feature a low flicker-rate. Products with a high flicker rate, such as fluorescent lights, can cause additional eye fatigue.

​However, in the event that these bulbs are not bright enough, or wind up being not to your preference, we are happy to offer a 30 day return policy. Simply let us know which products you would like to return, and we will issue a free return label.

Recommended LED Lights for Building a Tower Floor Lamps

Building tower lamps pseudo shoji style with lighted section 34" high behind a 5.5" sheet of acrylic on all four sides. Either white or a remotely adjustable color would be kind of cool. Could you recommend your products I should look at? 

It's a bit difficult to provide exact recommendations given the unique nature of your lamps, but it does sound like our high CRI LED strips could work very well for you. The LED strips are offered in a wide range of color temperatures, all of which offer 95 CRI or higher, providing excellent color quality both highlighting the Shoji material as well as illuminating the surrounding area.

Unfortunately, we don't have any solutions for remotely controlled color temperature, though that is certainly something we would like to see implemented in the near future!

If the floor lamps are for residential and home use, we would generally recommend our 2700K and 3000K options, which I have linked to below:

For commercial or office spaces, you may want to consider a higher color temperature such as 4000K or 5000K:

LED Panel Lights for Home Office Lighting

The space my wife and I use as a home office was originally designed as a sun porch. There's a single, small fixture in the middle of the room that provides very poor lighting to our desks. I was thinking of installing a surface mount LED panel (because the ceilings are relatively low) over each desk, but it's difficult to find LED panel lighting with >80 CRI. I'm looking for something that mounts close to the ceiling, is dimmable, and relatively long (to provide even lighting across a desk).

We unfortunately do not have any LED panel lights, and the requirement for dimmability makes this quite challenging based on the offerings we currently have available.

If you're willing to forego dimmability as a requirement, our T8 LED lamps housed in an appropriate ceiling fixture, or our T5 linear fixtures, could potentially be viable solutions for you. Both are available with 95 CRI and provide excellent light quality that should work well for a home office.

​I've included product links for these products below:

High CRI 93 LED Lighting for Residential

I am interested in bulbs with at least a 93 CRI. I see that you sell them. I would like to know what would be the best bulb for my family. The new bulbs sold in stores that are supposedly 60 Watts are not bright enough. What would be recommended and why is that your choice? 

Our 95+ CRI lamps sound like a great fit for you and your family. Our most popular option for residential installations is our CENTRIC HOME A19 lamps, which are available in a 60 watt equivalent brightness. The 2700K and 3000K color options are both excellent options for home use.

Below is the product page for the CENTRIC HOME A19 bulbs:

For more information concerning color temperature, please see our article below:

The new bulbs sold in stores that are supposedly 60 Watts are not bright enough. I see you recommended your Centric Home A19 bulbs. Does this seem brighter than the 60 W bulbs I could buy at the store and if so, is that due to the CRI? Why is that your choice to recommend? How many bulbs come in 1 pack?  

The 95 CRI bulbs will most likely provide the same amount of perceived brightness as an 80 CRI bulb that also emits the same amount of brightness (i.e. 60 watts). However, because the CRI is higher, a lower amount of brightness may be sufficient for task-oriented activities, as the improved color clarity may counteract the need for additional brightness.

​We unfortunately do not have any higher brightness bulbs so this would our best recommendation. Generally, we recommend increasing the number of lamps, rather than the brightness of any individual bulb, as this can help reduce glare and improve the light distribution in a space.

The 1-pack refers to 1 bulb.

​We would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED bulbs are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. 

LED Lighting Suggestion for Small Townhome of 1200 sq ft

Could you suggest a type of LED lighting for a small townhome ~ 1200 sq ft? I have 9 led lights in my downstairs and the room takes a pink/peach hue. I have white walls and want everything crisp, but cannot find a good brand or light.

Our high CRI LED lights should be a great fit for your home.

The first step in determining your lighting needs would be to understand the amount of brightness and the number of lights needed. Based on the square footage provided, we ran some quick calculations using our lumen estimation calculator ( which suggests approximately 26,000 lumens as your target brightness level.

​We would further recommend a 3000K color temperature which will provide your residential space with a comfortable but crisp white, light.

Will it damage the Centric Home Flicker-Free A19 bulbs using a dimmable power supply?

I bought a few Centric Home A19 bulbs from you. I was looking for a power supply for these bulbs, and I bought a few dimmable ones that can go 5%, 30% & 100% on light intensity. Will that damage my bulbs?

The CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs from your order is unfortunately not compatible with dimmer products.

However, we do offer other products which are compatible with dimmers, such as the Full Spectrum E26 BR30 LED Bulbs.

Are there any known health hazards using red phosphors in the bulbs?

I am outfitting my home with waveform-led bulbs. I was wondering if your bulbs give off UV rays to the occupants. Are there any known health hazards with using red phosphors in the bulbs? I am buying PN 4011.40, PN 4002.30 PN 4011.30 I am hoping that all your lights have reduced blue spectrum and are safer than the typical LEDs at hardware stores. I know that your lights carry the CE rating but are not UL listing. 

Our bulbs do not emit any UV rays, and all emitted electromagnetic waves are longer than 430 nanometers.​There are no known health hazards with red phosphor wavelengths as their peak wavelengths are at 630 nanometers or longer.

These photometric properties apply to all of the PN 4011 and 4002 product lines. For reduced blue light output, we would generally recommend high CRI and low color temperature lamps as they will generally offer the best mix of wavelengths to reduce blue light exposure.

Do you supply recessed integrated LED CRI 95 Lights?

I will be getting 5-6 recessed ceiling lights installed in about 10 days. Kitchen being remodeled for accessibility due to vision impairment I am looking for quality recessed integrated LED CRI 95. Do they exist? Or only as bulbs? I am also looking to have the tone to be adjustable. I prefer warm when not doing a task. 

Unfortunately, we currently do not offer any integrated LED light products which match the description provided.

Do you have any A19 E26 bulbs suitable for enclosed ceiling light fixtures?

I was wondering if you have any lightbulbs suitable for enclosed ceiling light fixtures for home use -A19 E26. 

I am happy to confirm that we offer A19 filament bulb products, which are able to be used within enclosed lighting fixtures. I have attached links to the products below, for your convenience.

Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential:

Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb:

Would full-spectrum light help night worker?

My brother is in NY for a month but he has a job 7 time zones away, which means he has to start work at 2 AM (his job ends at 10:30AM). So he goes to sleep at 6 PM. I was wondering whether a full spectrum bulb in the early hours would help his biological clock. In other words, would it create a daylight-like morning for him as he works the few hours before daylight.

Our lamps are indeed designed to mimic the natural daylight spectrum, and therefore our products would be a great fit for your application. While we aren't able to make any medical claims as far as your brother's biological clock and circadian rhythms, our lamps will indeed provide a lighting environment similar to morning sunshine (especially our 4000K color temperature).

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.

Do you have E14 Lamps?

Due to decreasing availability of incandescent light bulbs your product is truly interesting. However, at least in my corner of Europe, most bedroom lamps need bulbs with E14 screws. Is there something like that available? Or maybe some convertor or smth?

Unfortunately, we do not offer any E14 lamps, but you may be able to find some adaptors in any third-party retailers like Amazon.

Dimmable 3000K (>90) CRI 3000K Strip Lights with Triac Dimmer Switches for an Open Staircase Installation

I wish to put Strip Lights on an open staircase under each tread. I need help in determining the correct method to instruct the fabricators to install wires and what combination of power supplies/dimmers to use. I have 17 treads, each will have 48" of illumination - for a total of 21M. 

I intend to have each tread individually drop wires to the basement so that I can wire them all independently (would you recommend this?). I would like to do white, dimmable strip lights with high (>90) CRI, and so I’m looking at the centric home, 3000K strip lights. What’s the best way to do this? The Triac Dimmer switches indicate 150W only – so how would I use multiple power supplies (each at ~120W) with a single dimmer?

Our CENTRIC HOME LED strip lights sound like a great fit for your staircase installation. The 3000K and 95 CRI colors will be sure to add some excellent lighting to your space while highlighting your staircase.

There are several ways the proposed installation can be accomplished. The constraint, however, will be in the power capacity limitations of our TRIAC dimmable power supplies, which are 120 watts and 96 watts, for the 12-volt and 24-volt versions, respectively. Converting that into the number of stair treads, it looks like each power supply will have enough power to cover approximately 4 stair treads (5.5 watts x 4 ft x 4 stair treads = 88 watts).

As such, you will likely need 4 or more separate LED strip runs to be able to cover the entire staircase, with each run being powered by its own TRIAC dimmable power supply. The good news is that the 4 TRIAC dimmable power supplies can be connected to a single dimmer switch so that all of the LED strip runs can be dimmed in unison. For a connectivity diagram, please see our layout diagram below:

Additionally, in connecting the separate 48" sections between the stair treads, we do offer a variety of connectors that you may find helpful. Please see below for a similar diagram but with separate LED strip segments being rejoined using our various accessories:

It's mentioned that I can use a single Triac Dimmer to control 4 dimmable power supplies. However the dimmer indicates only ~100W for LED - and each of the power supplies would be ~100W x 4 =400W total.

Your calculation and interpretation there is correct. If the dimmer manufacturer recommends only a minimum of 100 watts, we certainly would not recommend exceeding that level.

We have generally seen that many dimmers support up to 600 watts, with a list of supported dimmers located here:

We have found that dimmer manufacturers have been providing two different wattage levels for incandescent / halogen and LED / CFL systems. We are not sure what their reasoning for this is, as we believe that our dimmable LED power supplies behave similarly to dimmable incandescent loads and therefore should not be significantly different.

​To ensure safe operation, however, we would recommend following the guidance of the dimmer manufacturers as they may have their reasons for the maximum ratings.

Lightbulbs mimic the natural lighting in two regions: the Mediterranean and the British Isles.

I'm looking for lightbulbs that mimic the natural lighting in two regions: the Mediterranean and the British Isles.

Unfortunately, we don't have any bulbs that mimic a particular geographic region, but we do offer a CENTRIC DAYLIGHT A19 lamp that will work in standard light bulb sockets. The bulb offers three different color temperatures of 4000K, 5000K, and 6500K which should work well for your needs.

​Please see below and let us know if we can assist with anything else!

Will your Full Spectrum E26 BR30 LED Bulb fit in the 4" cans?

I have 4" cans ready to be installed, and I want to purchase your Full Spectrum E26 BR30 LED Bulb 4011.50. Will the bulbs fit in the 4" cans?

Our BR30 lamps have a diameter of 3.75 inches at their widest point.​Since you have 4-inch can lights, you should not have any issues. The one thing to check for, however, may be any baffles or other accessories that may obstruct the lamp if they do not allow for an opening of 3.75 inches or wider.

Do you have a 2700K version of the BR30 LED Bulb?

Your product page mentions the 2700K version of the BR30 LED Bulb, but I can't select 2700K in the Color Temperature dropdown. Do you know when the 2700K BR30 LED Bulb will be available again for purchase?

Unfortunately, we no longer offer the 2700K color temperature for our BR30 LED bulbs.

That being said, depending on your installation we might suggest our 2700K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb as an alternative. 

Here's the list of 2700K products that we currently offer:

Difference in R12 values of NorthLux 5000 bulbs and the Absolute Series 5000 strip

I was interested in purchasing a high CRI solution for a studio and noticed that there is a really big difference in R12 values between the NorthLux 5000 bulbs and the Absolute Series 5000 strip. Why is there such a big difference and what wavelength does R12 correspond to?

Depending on the underlying technology used, the R12 value can vary quite significantly.

​The R12 value corresponds to wavelengths centered at approximately 460 nm. The reason our 95 CRI products (such as our NorthLux lamps) have a lower R12 value is that they utilize a blue diode as its light engine, which creates some distortion at or around the peak blue wavelength around 450-460 nm. On the other hand, our ABSOLUTE SERIES LEDs use a violet diode as its light engine, which does not create as much distortion in the blue wavelength range as it has a peak violet wavelength of approximately 420 nm.

​We generally do not find that R12 is as critical of a color metric as R9 is, but for a color-critical studio application, the added color rendering benefit may be of interest to you.

For further reference, we would recommend the following resources:

CRI/Ra test color samples (TCS), section titled "TCS 12"ABSOLUTE SERIES™ NEW SPECTRUM LED TECHNOLOGY, reference the first spectral diagram next to section titled "What's Different With ABSOLUTE™?"

Are there any issues with UV light from using the violet Diode?

Based on a strict definition of "UV" being wavelengths less than 400 nm, our ABSOLUTE SERIES LEDs do not contain any UV.​From a purely technical perspective, however, the violet wavelengths do contain a higher amount of energy, and may present a slightly higher risk. Depending on how sensitive the artwork pieces and materials are, you may want to keep that in mind.

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

Is there a way to waterproof the 365 nm strips?

I'm interested in your 365nm strips - any idea if there's a way to waterproof those? Or would putting them into some kind of plastic sleeve block the UV produced?

Unfortunately, we are unable to assist with waterproofing. The intended usage as described is beyond the scope of what we do, as we do not offer waterproof enclosures.

We discourage the use of our products in any installations where they may come into contact with water, including submersion. Doing so introduces safety hazards, and any contact that this product has with moisture will void the warranty.

As a final note, it has been our experience that plastic sleeves do indeed block the UV being produced by the realUV™ LED strip lights.

Do you have a BR30 or PAR30 bulb that has lower blue light?

I'm looking for a BR30 or PAR30 bulb that has lower blue light. The 2700K seems to fit the bill, but I don't see it on your website anymore. Are you planning to sell more of these in 2700K?

Unfortunately, we do not have any 2700K BR30 bulbs at this time, and do not currently have plans to manufacture them.

In the event that your space would specifically benefit from the 2700K color temperature, the Ultra High 95 CRI E26 A19 5W LED Filament Bulb for Home & Residential may be an option.

However, if you require the narrower focused light output of the BR30 bulbs, we do offer the Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential in 3000K, which is a bit cooler, but similar to the 2700K color temperature specified

Does the plastic diffuser cover cut down or mitigate the 365 nm strip LED output?

I'm interested in using your 365nm strip and am wondering if the plastic diffuser cover cuts down or mitigates the LED output. I'm using this in resin curing for headlight restoration purposes. 

The plastic diffuser is likely to absorb the peak wavelengths of the 365 nm LED strip light, so for maximum efficacy, we would recommend removing the diffuser cover if at all possible.

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.

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

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

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

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

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

Do you have waterproof and high ambient operating environment capacity LED products used in the sauna?

I need waterproof and high ambient operating environment capacity to be used in the sauna.

Unfortunately we do not have any LED products that can withstand the thermal and moisture requirements for a sauna application.

Healthier lighting for dark apartments

I live in an apartment which has no natural light. I want some healthier lighting as we approach winter to brighten up my living area during the daytime. Which product would your recommend?

We're sorry to hear that you apartment doesn't get much natural light! Those winter months, especially at the northern latitudes, can definitely get dark and gloomy.

We designed our CENTRIC SERIES™ LED bulbs with a focus on full spectrum (high CRI) and flicker-free light output. We offer the CENTRIC SERIES in both the DAYLIGHT as well as HOME options, which correspond to the daytime color temperatures of 4000K, 5000K and 6500K, and popular nighttime color temperatures of 2700K and 3000K.

Since you're looking for supplemental lighting during the day, we would recommend our CENTRIC DAYLIGHT series bulbs. 5000K is our most popular as it offers a nice balance between morning sunshine (4000K) and blue sky (6500K). All of our CENTRIC SERIES LED bulbs are completely flicker-free.

If you need to determine the number of bulbs you need for a bright enough space, we recommend checking out our lumen estimation calculator. By plugging in the dimensions of your room, you will receive a general recommendation on the number of bulbs you need.

LED strip layout for cove lighting

I have a room with dimensions 15' x 15' and vaulted ceilings that go to 17'. I would like to line the perimeter of the room with LED strip lights. There is a "cove" space for lighting and I will utilize this space to install the LED strips. What layout and parts would you recommend for a dimmable setup?

Our LED strip lights sound like a great fit for an indirect lighting application. Assuming room dimensions of 15' x 15' and that you want to install LED strip lighting along the entire perimeter, this would require a total of 60 feet of LED strip lighting.

Each 16.4 reel of LED strip lights requires a separate TRIAC dimmable power supply. To cover 60 feet, you will likely want to use 4 reels and 4 power supplies. Each power supply can be connected to the same wall-dimmer as shown below:

Finally, inputting room dimensions and ceiling height into our calculator below, we can confirm that the 60 feet of LED strip will provide more than sufficient levels of brightness for all activities.

Reason for enclosed fixture ratings

What is the reason your A19 bulbs can not be used in enclosed fixtures? Why am I able to use a 60W incandescent bulb, but not your bulbs which are only rated at 10W?

Our 10W A19 lamps may not be used in an enclosed fixture. The reason is that enclosed fixtures do not provide sufficient free airflow to keep the bulbs cool, and may lead to premature failure.

Although LED bulbs emit less heat than incandescent bulbs, they are much more sensitive to heat due to the internal electronics in the LED bulb. An incandescent bulb is essentially made just of glass and a wire element coil (filament). Therefore, although a 60W incandescent bulb may work fine in an enclosed fixture and emit lots of heat, a 10W LED bulb emitting only a fraction of the heat may still be detrimental to the LED bulb because its components are much more sensitive to heat.

How many lumens do I need for my space?

Check out our Lumen Estimation Calculator

Brightness, of course, is one of the most fundamental and important aspects of an LED bulb. All of our LED bulbs are listed in lumens as well as a wattage equivalence number. It is difficult to provide any absolute answers when it comes to recommended lumens number for a given space, but you may want to consider the following three guidelines:

800 lumens = 60 watt IncandescentEvery 800 lumens gives you approximately the same amount of light as a 60W incandescent bulb. If, for example, you're trying to reproduce the brightness of 4 incandescent bulbs, make sure you have approximately 3200 lumens (4 x 800 lumens).

450 lumens = 1-ft T8 Fluorescent4-ft T8 fluorescent lamps emit approximately 3000 lumens. However, because it emits light in all directions, much of it is "lost" in the fixture. When replacing T8 fluorescent lamps with an LED solution such as LED strip lights, we recommend budgeting 450 lumens per foot as a direct replacement. For example, a 2-lamp 4-ft T8 fixture would require approximately 3600 lumens (8 x 450 lumens).

1000-3000 lumens per 100 Square FeetIf you're lighting up a new space or don't have a reference point to compare with incandescent or fluorescent lamps, you can also estimate your lighting needs by square footage. For every 100 square feet, 1000 lumens is sufficient for low-light level areas such as living rooms and lounge areas, while task-oriented spaces may require up to 3000 lumens or more.

Check out our Lumen Estimation Calculator for an interactive way to calculate the number of lumens or lamps needed for your space.

Finally, keep in mind that we offer a free returns & exchanges program. We encourage customers to test out our LED strip lights prior to installing them to make sure the brightness and color meet or exceed their expectations. As long as the LED strips are in their original condition (e.g. segments uncut, adhesive liner not removed), we will gladly accept returns and exchanges of LED strip lights. See our full return & refunds policy here.

A19 bulbs in semi-enclosed fixtures

The product page for the CENTRIC HOME™ A19 bulbs says they are not suitable for enclosed fixtures. Would they be OK to use in semi-enclosed fixtures? For example, I have some floor lamps with cone-shaped lampshades that surround the bulb. How about desk lamps with similar cone-shaped lampshades?

The 10 watt A19 lamps are not, as you correctly mention, not suitable for use in enclosed fixtures. Our definition of enclosed fixtures is defined as any fixture that completely seals off air flow from the ambient environment. The most commonly seen enclosed fixtures are those in residential ceiling fixtures, where a glass housing completely encloses the fixture base.

On the other hand, table and desk lamps that are partially enclosed will not present any issues with the enclosed fixture rating. Because these fixtures allow for sufficient free air flow, there are no concerns with respect to thermal damage and premature failure.

Which is safer - DC 12 volts or 24 volts?

Do 12 volt LED strip light systems also have lower shock risk than 24 volt? I have heard that "it's not voltage that kills, it's current" - in which case the 12 volt LED strips would appear more dangerous given that it has twice the amperage.

Generally, we believe that "shock risk" increases as the voltage increases. At a very basic level, this suggests that 12 volt LED systems would have the lowest possibility of causing an electric shock, while 24 volt would be slightly higher but still relatively low, and 120 volt line voltage would be much higher in terms of the possibility of causing an electric shock.

Shock risk, however, is not the same as the potential to cause bodily harm or injury. The zap from static electricity that you feel on a dry winter day, for example, has a very high voltage of tens of thousands of volts, but does not cause any harm due to the inherently low amount of energy (as you mention, it lacks the "current which kills").

The primary reason lower voltage systems have a lower shock risk, is simply due to the fact that low voltage systems generally lack the voltage potential to overcome the high electrical resistance in our human skin. Therefore, a 12 volt system, even one with a higher amperage rating, is seen as generally lower risk because the 12 volts is usually insufficient to penetrate skin and other objects.

Low voltage systems do have a lower risk, but that is not to say they are risk-free. Please use caution and consult with an electrician when installing any LED systems you are not familiar with.

How do I know how many bulbs I need for my space?

One of the most fundamental questions before embarking on a residential or studio lighting project is knowing how much light is enough? We've all had experiences where it's just too dim to see properly, so under-estimating the amount of light needed is an obvious concern. Installing too much light, on the other hand, can also be problematic, as this can lead to uncomfortably bright spaces and unnecessary expense.

One resource we offer at Waveform Lighting is the Lumen Estimation Calculator. This calculator will ask some basic questions about your space, such as the physical dimensions as well as the brightness needs (e.g. residential space or an art studio, or something in between?)

Based on these inputs, the calculator will provide an estimated "lumens" recommendation. This is the total amount of brightness that would be appropriate for a particular space, given the details inputted. From there, various lighting options can be explored, given the total amount of brightness required.

Mounting lights onto a window with no incoming light

I currently have a window that does not have any natural light, because it faces a wall just 1 inch away. I'm hoping to simulate natural light with one of your lighting options. What do you suggest?

Our full spectrum lighting options sound like a great solution for your situation.

In general, our 4000K or 5000K products with 95 CRI will provide you with the best simulation of natural daylight. Our CENTRIC DAYLIGHT A19 bulbs fit into standard screw-base sockets and maybe a great, straightforward option for you.

Depending on the dimensions and mounting options of your window, our T5 integrated linear fixtures may also be worth considering.

The T5 integrated linear fixture sounds great.  The inside dimension of the window is 70 inches wide and 46 inches tall.  Do you think a single 2-ft fixture will be sufficient? 

Based on these dimensions, up to three 2-ft T5 light fixtures could be used to evenly fill the space.

These 2-ft T5 light fixtures can also be daisy-chained together, which means they can all connect to a single power outlet.

Since the window faces the outside, there is some condensation on the window glass. Do you think condensation would be an issue?

Based on the information available to us, it is difficult to say with any certainty whether or not condensation would still be an issue for these fixture mounting solutions.

It may be worth investigating for the presence of moisture on or near your window, in order to have a better idea of the safety hazards which might be present. If, for example, visible water droplets are present, that would certainly be a situation where condensation would indeed be a safety concern.

Putting LED strip lights on the backs of shelves in a three section book case

I am putting lights on the backs of shelves in a three section book case. There are a total of 4 shelves on each section and a section in the middle with one shelf to light. The tape light I choose is 3000 K. The shelves each are all 30 inches with the exception of the one in the middle being 40 inches. Total length of lighting needed is 24 ft. There is about 18 in of jumpers needed between the shelves.

Would you recommend two 12 volt power supplies in 2 parallel 16 ft runs, or one 24 volt power supply in one 24 ft run wired in series?

Generally speaking, our LED strip lights are limited to 16.4 ft per run due to power supply and/or maximum run length constraints. For your installation of 24 ft, you will likely want to install two separate LED runs​, while ensuring that neither run exceeds 16.4 ft.​

Below is a link to one of our layout diagrams which you may find useful in determining the configuration and components needed for this setup:​
