Recommended High CRI LED Lights for Art Gallery Lighting

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

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

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

Full Spectrum Clip-on Magnifying Light for Painting Studio

I need to buy a flexible clip-on magnifying light with full spectrum light for my painting studio. I was investigating some products that claim to have different levels of lighting. I read a lot on this site as I was not convinced that they provided the full spectrum needed for painting art. I like what I saw on your site but where do I get the fixtures that will accommodate your bulbs?

Based on our review of the best-selling magnifying LED lights for painting on Amazon, it appears that the majority of the results utilize embedded SMD LED panels that surround the product viewing lens. As such, it does not appear that our products could be installed within the majority of these items.

However, we are happy to offer several alternate lighting products which our customers have utilized within their studio spaces, including the NorthLux™ 95 CRI T5 LED Linear Light Fixtures, and the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio product. That being said, neither of these products is directly comparable to the magnifying LED light mentioned.

Full Spectrum LED Lighting for Big Aviary and Horticulture

I would like to confirm that your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light can be used for lighting in my indoor aviary (dimensions: 80" H, 86" L, and 62" D). I cannot use the Full Spectrum BR30 LED Bulbs 4000K / 5000K / 6500K as I would need several of them and my ceiling is glass (the aviary is inside the sunroom). If my assumption is correct, can the tubes be plugged in or are they only hard-wired? I can only plug them in based on my setup. If there is no plug-in version of the tubes, are there alternative LED strips I can use that are full-spectrum? Finally, are the horticulture tubes hardwired or can they be plugged?

We can confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights are compatible with 4 ft fluorescent tube light fixtures which utilize the G13 base.

However, it might be helpful to know that these lights are not compatible with all ballasts present within fluorescent fixtures. Generally speaking, product incompatibility with ballast models may cause flickering, or a lack of functionality. For a full list of ballasts that have been tested as compatible, please review this link:

For further instructions regarding the installation methods available for these lights, we have provided a link to the product specification sheet below.

Product specification sheet:

If you would like to let us know which light fixture models you intend to use for the indoor aviary, we would also be more than happy to check to see if they are compatible with these lights.

Full Spectrum LED Lighting for Grocery Store Installation

I'm an architect looking for lighting that mimics daylight as closely as possible for a grocery store installation. 

We have attached two product links below that we believe might be a great fit for your grocery store installation.

As mentioned, please feel free to take advantage of our 30-day return policy for your order. If the products wind up not working well in the space, simply let us know and we would be happy to promptly issue a prepaid return label.

Everything You Need to Know About Full Spectrum Lighting:

Full Spectrum LED Lights for Imaging Applications

I am currently looking into purchasing a full-spectrum light source to use in imaging and was wondering if you had any recommendations. Also, would it be possible to adjust the intensity? 

One of the most popular product options we've seen has been our T5 linear lamps, which can be installed quite easily in a variety of locations. These lamps feature 95 CRI which provides full spectrum and excellent color accuracy, features which are essential for accurate imaging applications.

Our D50 product in particular meets the ISO 3664 standards for color accuracy and should be a great option for your needs. Please see below for the product link:

The only downside is that these T5 lamps cannot be dimmed, so you will need to be able to work with a fixed brightness level.

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.

Full Spectrum LED Lights for Home Gym and Film Studio

I am converting a barn into a home gym that will also be used as a film studio to create content. I've been told that full-spectrum LED lights would be ideal. Hoping you can guide me to determine if your products are right, and which ones to choose. 

Based on the details that were provided for your gym and studio space, there are a few products that we might recommend. We would be more than happy to provide further details and advice about each product mentioned upon request, as well.

For example, we sell the NorthLux™ 95 CRI LED Shop Light Fixture, which is a great option for installations where non-permanent lighting options are preferred, as it can be easily re-arranged and mounted using the included hanging chains and hooks. This integrated product requires no accessories and can be daisy-chained with other units, but it is unfortunately not compatible with dimmers.

If you would prefer to utilize new T8 tube light fixtures in your space to have the benefit of easily swappable lighting, we might recommend the NorthLux™ 95 CRI T8 LED Tube for Art & Studio products.

Further, we also offer our LED strip light products. As an overview, these products are sold in reels and are compatible with in-wall power connections and wall dimmers. These strip lights can be configured in multiple ways and can be mounted using products such as our aluminum channels. These lights are also compatible with third-party lighting systems such as Lutron Caseta.

For more information regarding our LED strip lights, we have attached an article from our website below.

LED Strip Lights: Everything you need to know before you buy:

By using our lumen estimation calculator tool, we estimate that the space described would be fully illuminated by 18,821 lumens. As each product emits a different amount of light, we might recommend either 5 LED shop light fixtures (at 4200 lumens emitted per fixture), 11 T8 LED tube lights (at 1800 lumens emitted per light), or 42 feet of LED strip lights (which emit 450 lumens per foot) for your space as options.

Does the Avian A19 LED Bulb need to be installed closely to birds for full-spectrum light benefits?

Does this light bulb need to be right over my conure cage and perching area are can it be used in the light fixture in the ceiling in the room he is in? I saw some other lights have to be really close to birds for them to get the benefits of the full spectrum light- but they also can cause burning to the bird's eyes from being close.

We do not have a specific requirement as far as distance away, but in general, we recommend installing a larger quantity of bulbs located far away, rather than a fewer quantity installed very close.

The overall goal would be to replicate natural daylight, which actually "rains down" from a very wide 180-degree dome (i.e. the sky).

T8 Full Spectrum LED Lights for Automotive Paint Booth

I own an auto body shop and I just bought a new paint booth and was researching lights. It has 10 light fixtures which take 4 bulbs each. It requires T8 bulbs(4ft). From my research, I think I should buy full spectrum 5000K bulbs. What product do you think fits my needs? 

Based on the details provided, we believe that the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product could be a great option for your paint booth.

The 5000K color temperature option is what we generally recommend for industrial installations and color evaluation purposes, which can be noted in the article below:

Which LED Light Color Temperature Should I Choose:

However, please note that we are happy to offer a 30-day return policy. If the 5000K option winds up not working for your space, simply let us know and we will issue a prepaid return label.

Do you offer full-spectrum LED lights that contain UV-A?

I was wondering whether you sell any full spectrum lights that also contain UVA.

Unfortunately, we do not currently sell UV-A products that also offer full spectrum output at this time. We apologize!

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:

Blue Light, Melatonin, and Circadian Rhythms:

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.

Blue Light, Melatonin, and Circadian Rhythms:

Difference Between the BR30 Bulbs

Other than color temperature, what is the difference between the Ultra High, Full Spectrum, and the NorthLux 95 CRI BR30 LED Bulb? I'm about to move into a large studio condo and am considering my lighting options. In my previous places, I've used SoLux 4700k 12V MR16 halogens and loved their light, but they are not compatible with our fixtures. 

We can confirm that the color temperature options available are the only differences between the three products referenced, as they are of the same product family. This can be noted by the shared part number on each product page.

However, each product offers the same benefits of full spectrum, high CRI lighting, as well as a low flicker rate.

We do apologize for any confusion which may have arisen, as these products are displayed on multiple pages for marketing purposes.

LED Grow Lights for under-cabinet and herbs and sprout seeds

I remodeled my kitchen and want perfect under-cabinet LED low profile strips but I want to grow herbs and sprout seeds on my kitchen counter, so am looking for full spectrum as close to daylight bright lighting. Which accessories do I choose of yours to build the perfect lighting in (4) 24” lengths and one 18” length? I have a dedicated switch on the wall to control them.

Based on the details provided, we can recommend our 5000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail products. The 5000K light which is emitted by this product will be very similar to that of natural, bright daylight. 

To connect the individual LED strip light segments, we recommend the Solderless Connector for Single Color LED Strip products.

When this product is paired with the 12V TRIAC Dimmable Power Supply for LED Strip, it can be adjusted and controlled using a wall dimmer product.

Here is a LayoutMap which illustrates this configuration, which might prove to be useful.

LayoutMaps™ - LED Strip Light Layout 3001-1B:

We also offer the Aluminum Channel for LED Flex Strip products which can be used for easily mounting the LED strip lights. However, the lengths currently available may be too long for the LED strip light lengths that were described. As far as we can tell, one 16.4 ft reel of the LED strip lights, as well as one unit of the dimmable power supply, should be sufficient for your installation.

Full Spectrum LED Light for Car Repair/Restoration

30 ft. X 40 ft. with 12 ft. ceiling. All white inside. Used for car repair/restoration. Need light to reach under car lift. Did I do the calculator right? 120,000 lumens? The full spectrum is nice. 

I have attached the store links below for the products which were discussed during the call. If you could provide further details about the space, we would be more than happy to provide some more specific product recommendations as well as product quantity suggestions.

The NorthLux™ 95 CRI LED Shop Light Fixture was the primary product which was discussed. Although this item is currently back-ordered until February, this integrated fixture can be easily hung using the included chains and hooks. This product can also be daisy-chained together for easy installation.

In the event that you would prefer to use mounted ceiling fixtures which utilize tube lighting, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product.

For the installation which was described, we recommend the 5000K color temperature option. The light which would be emitted by 5000K light sources would be neutral, balanced, and very similar to natural daylight.

LED Lights to Stimulate Daylight for Winter Depression

I am looking for a lamp that simulates daylight as accurately as possible to combat my winter depression. 

I'm not sure exactly which light fixtures are being used in my house. They appear to be standard spot lights. I sincerely doubt there is anything special about them. I am looking for a colour temperature of about 5000K - 6500K.

I'm interested in your full-spectrum products. Whatever reproduces the spectrum of sunlight must be the best. Let's take the LED strip as the starting point and figure out a solution around that. I would also like it to be dimmable if possible.

The closest measurement I can get is 13 metres for my small room and 30 for my large room.

Based on your needs, it seems as though the ABSOLUTE SERIES LEDs at 6500K would be the best fit for you. From a spectral and chromaticity standpoint, this is the product that most closely resembles natural daylight at noontime, and should be an excellent choice.

​To address some of your questions about the technical aspects of the product:

The ABSOLUTE SERIES LEDs utilize a novel approach to generating white light. Specifically, it uses a 420 nm wavelength die to excite three different phosphors (blue, green & red) across the visible spectrum.A standard LED will typically use a 455 nm wavelength die to excite two different phosphors (green & red).Because the ABSOLUTE SERIES uses the lower wavelength die in conjunction with the blue phosphor, it provides far better energy coverage across the blue wavelength range. This should be very helpful in ensuring that sufficient levels of blue energy are present in the light source, just as there is in natural daylight.One quick way to numerically confirm this is through the CRI R12 metric, for which the ABSOLUTE SERIES scores 90+, compared to our standard LED lines which only score in the 70+ range despite having a 95 CRI rating. Additional information on the product line can be referenced here.

Regarding the power supply, we can confirm that the ABSOLUTE SERIES™ LED Flexible Strip product would require a DC power supply for every 16.4 ft (5 meter) of length, such as our 12V FilmGrade™ DC Power Supply for LED Strip. Our DC power supply is compatible with global input voltages (100 - 240V AC, 50-60Hz), though you may require an additional wall socket adapter. 

​Further, the ABSOLUTE SERIES™ LED Flexible Strip product can be paired with the FilmGrade™ Flicker-Free LED Dimmer product for additional dimming capability. 

Depending on your installation, we might also recommend placing the LED strip lights within an enclosure which features a diffusor, such as our Aluminum Channel for LED Flex Strip product, which is available in 'flat' and 'corner' options.

​For a detailed illustration of the configuration options available for this product, the below links may prove to be useful:

LayoutMaps™ - LED Strip Light Layout 3002_3D:

LayoutMaps™ - LED Strip Light Layout 3002_3E:

It is going to be pretty difficult to install a power supply for every 5 metres of strip. If I run a strip around my whole room, I'm going to have a huge number of power supplies everywhere. Is there some way to hide them?

Unfortunately, we don't have a proper recommendation to hide the power supplies. However, the cords for the DC Power Supply products are of a decent length, and could be helpful in hiding the power supply some distance from the LED strip lights.

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).

Ultra High 95 CRI A19 5W LED vs CENTRIC HOME A19 10W LED Bulb

I need a single bulb that's around 400 lumens and 2700K, so I was looking at your Ultra High 95 CRI A19 5W LED. However, the description does NOT mention that it is flicker-free nor does it mention that it's full-spectrum (while your CENTRIC HOME A19 10W LED Bulb does mention these traits). Is the 5W a lower-quality product? Or is it just fewer lumens?

I can confirm that the 2700K Ultra High 95 CRI A19 5W LED Filament Bulb features the same high CRI of 95+ as the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb. As such, both products are considered to be full-spectrum.

However, the Ultra High 95 CRI A19 bulb does not offer the same flicker-free performance as the CENTRIC HOME™ bulbs. The flicker-rate of the Ultra High 95 CRI A19 bulb is similar to that of traditional incandescent bulbs.

The benefits offered by the Ultra High 95 CRI A19 bulbs can be found in the warmer color temperatures available, as well as the compatibility with dimmers. In contrast, the CENTRIC HOME™ is not dimmable.

Difference between Northlux and Full Spectrum BR30 Bulbs.

Could you please tell me what differences to expect between a 5000K Northlux BR30 bulb and a 5000K Full Spectrum BR30 bulb? 

The NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio lights is the same product as the Full Spectrum E26 BR30 LED Bulbs. As such, there are no differences between the two products.

We do apologize for any confusion caused as the product is shown on multiple pages for marketing purposes. This can be noted by the shared part number listed in the item description for both products.

Light Color Spectrum Behind a Prism

I'm doing research for an art installation. With your lights, if I put the behind a prism, will it diffract the entire color spectrum to see the rainbows?

Because our products are designed with a CRI higher than 95, it means that they provide full spectral coverage and emit full spectrum light which is extremely similar to the spectrum of natural daylight.

As such, if our lighting products are placed behind a prism, the light refracted by the prism should produce an effect similar to what you would see with natural daylight.

Full Spectrum Strip Lights for Bathroom Installation

I am in the middle of a master bathroom renovation. Are the 4000k Centric Daylight strips full-spectrum? If not, is there any custom strip that can be made or can you recommend any other product or manufacturer for my application?

We can confirm that the 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail product feature an ultra high 95 CRI, offering a full spectrum of light output which is extremely similar to that of natural daylight.

In case it proves to be useful for your installation planning, further information regarding CRI and full spectrum can be found at the links below.

Full Spectrum Lighting:


Full Spectrum E26 BR30 LED Bulb Specs and R9 value

I would like to know the specs (including R9 value) for your Full Spectrum E26 BR30 LED Bulb.

For our 3000K and 4000K, our recently measured R9 values were 90 and 97, respectively. Please let us know if we can assist with anything else!

Recommendation for Full-Spectrum Bird Room Lighting

I breed birds, primarily finches, in a 12' x'20' room with 8-ft. ceilings. Currently, the room is lit by two 4-ft. 2-tube LED ceiling-mounted fixtures which are hard-wired on a single circuit controlled by a wall switch/timer. I want to switch to full-spectrum lighting and it looks like your channel-enclosed strip lighting is a good option. Need help in making the right selections, preferably from someone familiar with birds.

Our LED products sound like a great fit for your space, and we look forward to working with you to help improve the lighting in your space, particularly concerning avian health.

Generally, our approach to avian lighting is to recommend lighting that best matches natural daylight at a spectral level, as that is typically what birds expect and need from a lighting perspective.

​For your installation, we would have to recommend our flicker-free full-spectrum LED tube lights. Our CENTRIC DAYLIGHT LED tube lights feature 95 CRI and can be used in existing 4-ft fixtures, and maybe a great way to immediately convert the lighting in your space to flicker-free and full spectrum lighting, without any need for extensive fixture reconfiguration.

Please see our product link below:

Does your full-spectrum fluorescent fixtures 5000K can be used for avian applications?

I've been using full spectrum fluorescent fixtures with 5000K and 90+ CRI, and am considering ordering from your 98 CRI products for my parrots. Do you know if your LEDs can be used for this purpose? There doesn't seem to be much literature out there on replacing full-spectrum fluorescents in aviaries with comparably rated LEDs.

Our high CRI LED products sound like a great way to enhance your existing fluorescent lighting products for avian applications.​Our 95+ CRI rating indicates that our lamps do an excellent job of recreating natural daylight, which is something that fluorescent lamps struggle to do (the highest CRI values are generally 90 for fluorescent lamps).​The one difference, however, is that LED lamps generally do not include UV radiation. Some research indicates that birds can benefit from UV radiation, so if that is a concern, you may want to be aware of that when considering LED lamps.

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.

Difference between natural "daylight" vs natural "sunlight"

I see that you characterize the difference between 4000K/5000K and 6500K bulbs as being similar to the difference between natural daylight and natural sunlight. I'm still unclear on what the difference is between daylight and sunlight?

Daylight would be the clear, bluish light coming in through a north facing window. No direct sunshine coming in, just the light from the crisp, blue sky.

Sunlight, on the other hand, has a warmer, yellower quality to it -  imagine the soft, early morning sun rays streaming in through your windows.

Some of our customers prefer the warmer "sunshine" look of our lights (4000K/5000K) while others prefer a crisper, whiter "daylight" look (6500K). Unless you are working in an industrial or color-critical environment, this decision is completely up to you and a matter of personal preference!

With respect to color temperature selection, you might find the following infographic useful:

LED lights to replicate natural daylight in office space

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

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

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

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

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

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

Check out our infographic on color temperature selection below:

How to "warm up" my office with better lighting

My office currently has bright fluorescent lighting that feels dark and cold. I want to “warm up” the office with lighting  that will provide a warm and homey atmosphere. What full-spectrum lamps should I purchase?

It sounds like what you are looking for are warmer color temperature bulbs. For residential applications, we typically recommend color temperatures below 3000K. Although you are located in an office setting, since you're trying to replicate a similar, more relaxing atmosphere, we would recommend installing residential bulbs in your office.

For example, here is a 3000K bulb that might work well for your needs:

Also, make sure that the lighting has high CRI (95 CRI) to ensure that the colors in your space appear natural and accurate.

The term "full spectrum" is commonly associated with "healthier light" that can help provide supplemental light, especially during the darker winter seasons. Keep in mind, however, that full spectrum lights are designed with higher color temperatures (4000K - 6500K) that replicate natural daylight. These color temperatures generally do not produce a relaxing, calming environment. Instead, they are more commonly used to provide an energetic and vibrant atmosphere.

What color temperature best approximates natural sunshine?

For those who spend lots of time indoors, installing LED lights that mimic natural light may be a top priority.

The color temperature of natural light can be difficult to pinpoint as it can range from 4000K to 6500K or higher, depending on the time of day, weather, latitude and season.

If you're after the warmer feel of natural sunshine (as opposed to daylight), 4000K may be a great option for you. 4000K can be described as early-morning or late-afternoon sunshine that comes in through a south-facing window.

5000K and higher color temperatures are also close approximations of natural light, but they are more aligned with natural daylight, rather than natural sunlight. Think of a more neutral, white light coming in from a north-facing window on an overcast day.

See below for a photo except from our CENTRIC DAYLIGHT A19 bulb product page:

Flicker-free full-spectrum lighting for autism?

We have been reading that flicker-free and full-spectrum lighting might help with autism. What would you recommend?

We currently do not have any internal data or testing to verify this, and our lamps are neither approved nor marketed for treating any medical conditions or disorders.

On the other hand, there are several published studies which have linked stroboscopic flicker to autistic behavior, along with a range of other symptoms such as seizures, fatigue, eye strain. Flicker-free lighting may be an effective approach to reduce or eliminate the amount of flicker present in an indoor space and assist in promoting a healthier lighting environment.

The link between full-spectrum lighting and autism appears to be less established. Full spectrum lighting is a relatively vague marketing term, but the general idea behind it would suggest that a full-spectrum lamp provides a light spectrum that better approximates natural daylight. As such, the use of high CRI lamps (a better way to quantify "fullness spectrum") may be an effective way to introduce lighting that more closely resembles natural daylight, especially during daytime hours.

Waveform Lighting offers both flicker-free and 95 CRI LED lamps which may be an excellent options to consider. See below for our CENTRIC DAYLIGHT products, which can be used in a variety of residential or commercial (as well as classrooms and offices) locations:
