  • Product Overview

    Waveform Lighting's CENTRIC™ line of LED lights provides lighting that centers around you. CENTRIC DAYLIGHT™ T5 linear light fixtures provide light output that is free of optical flicker and a full spectrum color that approximates that of natural daylight. If you are looking for more natural daylight but are limited by geography, season or window placement, these lights will give you light that is both healthy and energizing.

    Flicker-free light output means that the rays of light emitted by the bulb are constant and uninterrupted, so you can rest assured knowing that the negative health effects such as headaches, fatigue and eye strain - previously associated with artificial lighting such as fluorescent lights and early LED bulbs - are eliminated.

    The CENTRIC DAYLIGHT™ T5 LED linear light fixtures are integrated light fixtures that operate from any standard AC 120 - 277 volt power outlet. No need to worry about fixture compatibility, ballasts, drivers or anything else - simply plug the lamp in and you'll be up and running in seconds!

    Included are accessories for mounting via magnets or screws, allowing for installation in a wide variety of locations such as trusses, crossbeams, rafters or old fixtures for general area lighting, or under wall-cabinets or inside workstation fixtures for task-oriented and localized lighting.

Choose Your Daylight


Our CENTRIC DAYLIGHT™ lights are offered in a range of color temperatures. 4000K provides a warmer, softer white that matches the shade of morning sunshine. 5000K has a more balanced, noon sunlight color, while 6500K provides a crisp, high-energy light similar to what you would see from a north-facing window.

All color options provide 95 CRI, full spectrum light that very closely matches natural light.

Flicker-Free & Healthy


Some LED lights will produce rapid flicker or pulses that aren't immediately visible to the naked eye, which can cause headaches, nausea and eye strain. Our CENTRIC SERIES™ products include additional electrical circuitry to achieve a truly flicker-free light output that produces a comfortable and stable light level. Learn more about flicker here, or watch our video demonstration below.

Full Spectrum & 95 CRI

CENTRIC DAYLIGHT products offer true full spectrum light, as measured by the Color Rendering Index (CRI) and CRI R9 metrics. With a 95 CRI, 80+ R9 rating, our lamps offer the closest reproduction of natural light in the industry.

  • Frequently Asked Questions

    • What is the difference between 4000K, 5000K and 6500K?

      These color temperature options correspond to the various shades of natural light. 4000K is similar to the warmer and softer shade of morning sunshine. 5000K approximates the bright sun during mid-day, while 6500K is most similar to the crisp, blue color of the sky.

      The choice between these colors is completely up to you! There is no correct answer, and this is a question of preference.

      Regardless of your choice, all color options feature 95 CRI and flicker-free light output, which will provide you with all of the benefits of full-spectrum light.

      Below are some articles that go into further detail:

      Difference Between 5000K and 6500K

      4 Things to Consider Before Buying 6500K Bulbs

      Still not sure? Take advantage of our 30 day free-returns policy to try out the different colors. If you don't like it, simply let us know and we'll send over a return label.

    • Do these bulbs emit blue light?

      Yes, they do!

      You may have read or heard about the concerns regarding the blue light hazard. Excessive blue light exposure during evening hours is certainly a concern, but blue light is an essential and important part of our daily lives, as it is extremely abundant in natural daylight (the blue sky!) and an important signal to our bodies and circadian rhythms.

      CENTRIC DAYLIGHT™ lights are the industry's best approximation of natural daylight (95 CRI), and therefore contain similar relative levels of blue light in the spectrum as natural light.

      You can think of these lights as mini suns that you can turn on and off at the flip of a switch. If you are concerned about blue light during evening hours and the potential impact on your sleep, we would not recommend using these bulbs at night when the actual sun has already set.

      During the daytime, however, these lights are an excellent way to supplement or substitute for natural light.

    • How many lights should I install in my space?

      We generally recommend installing 1 ft worth (450 lumens) of these linear lights for every 5 square feet of space. Simply divide the square footage of your space by 5 to get the number of bulbs needed. For example, a 80 square foot area would require 80 divided by 5, or 16 feet of linear lights. A 4-pack of our 4-ft light fixtures would be a perfect fit for an installation location of this size.

      While this may seem like a lot of brightness, do keep in mind that daylight color temperatures generally require a higher level of brightness for comfort due to a phenomenon described by the Kruithof curve.

    • Are these bulbs good for visual arts, scientific or industrial applications?

      These bulbs are a great fit for many applications that require a simulation of natural daylight.

      For technical or visual arts applications that depend on visual assessment and a closer adherence to international standards such as D50 and D65, we recommend our NorthLux™ Series A19 LED lamps.

    • Are these lights dimmable?

      Unfortunately, these lights are not dimmable. This means that they cannot be used on any electrical circuit which has a dimmer installed, even if you keep the dimmer at the maximum setting at all times.

    • Do these lights emit any UV radiation?

      These lights do not emit any ultraviolet radiation. The light output covers the entire visible spectrum between 420 nanometers and 800 nanometers, but does not go below (UV-A) or above (infrared).

    • Do I need a separate light fixture for this product?

      These T5 linear light fixtures do not require any other housing or light fixtures for use. Simply mount them using the included magnets or screws, and plug the fixture into a standard wall outlet.

    • What is the voltage range of these lights? Can they be used overseas?


      The voltage range of this product is AC 90-240V and 50-60 Hz, which covers all global voltages. As such, they can safely be used internationally without any issues. The internal circuitry adjusts for the input voltage automatically, and does not affect the light output or performance of the lamp. The light fixtures use a standard North American two-prong plug, so international locations may require a plug adapter.

Great Color Rendering

My wife uses this CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixture to brighten her Art studio. The light distribution & color rendering is outstanding, it made a huge difference in perception of color as she painted. The unit is light and easy to install. A couple if things to pay attention to: the power cable is quite short and the magnetic fixture clips are a bit weak to securely anchor the fixture. The regular clips work great. Also, working at night under a 6500K light will keep you awake, that may be a bad thing, but if you are working on a deadline it is helpful.

June Brought
Love these lights ! Great service !

I got two 5000K tube lights for the work area in my kitchen ; the full spectrum aspect of these bulbs is apparent ...not too blue, not too yellow, and no flickering. Easy to install. The first shipment was lost in transit, and Waveform sent out new ones immediately when I emailed them with the tracking info. Highly recommend.

beautiful light

Lovely light -- thank you.

works as advertised

works as advertised. But would be even better (i) if the color temperature and brightness were adjustable and (ii) if the max lumens were even higher.

Note that the higher lumen version is twice as long as the lower lumen one!

A simple, versatile solution

These have been a quick and easy way to add light to the dark spots in my home. Over and under kitchen cabinets, behind the lip on my wall unit, replacing old fluorescent fixtures in the closets... There are many possibilities. Attach a small piece of metal to potential mounting locations in your room with 3M Command strips, clip the included magnetic attachment to the fixture, and now you've got a sturdy, yet easily repositionable line of high-quality light. It takes very little thought and time to get an excellent result: find dark spot, place fixture.

Here are some photos of a temporary mount I tossed together while testing different lighting positions. Definitely an amateur's work, but hopefully you can see 1) the dramatic improvement and 2) how easy and non-destructive it is to put up and take down.

Great lights for the office!

Purchased 1 to test now coming back for batches of 5 as we expand

Excellent lights, excellent service

After ordering substandard lights from other companies, I stumbled upon waveform. I purchased 6500k lights for growing microgreens. I used 2 Rows of lights for every rack that grows my 1010 trays of greens. Since installing these lights, I haven’t lost any microgreens. They are a little bright in my kitchen but I taped cardboard on my racks to shield my eyes.
The customer service is the best I have found. After I contacted them with a faulty light, they immediately sent a replacement. I had a faulty light with a different company and never heard back from them. The other company I worked with, the owner seemed annoyed by all my questions. This company answered all my questions with kindness and respect.

What I also love about these lights is that when you daisy chain them, the light is continuous.
The only improvements I’d like to see is longer cords and the daisy chain connector to not be installed on each light. I’d like the ability to always have the on/off switch facing me.
A master on/off switch would also come in handy for those long strings of daisy chained lights. None of these are deal breakers for me because over time, I plan to purchase more lights to replace the substandard ones I had purchased before these.

You get what you pay for. These lights are worth the cost!

Very nice lighting

Bought two (4000K and 5000K) to help us plan lighting for new home. Very pleasant. Look forward to living with them in several locations in our new home. Am frustrated they aren't dimmable. And I don't understand their short cords. (We've been running our two samples on a 12' household extension cord for several weeks, and they seem unaffected.)

In addition, I really appreciate waveformlighting.com; very informative and well written. Thanks.

Cara Beasley
Fantastic lights!

These fixtures are great! Super easy to use and assemble, everything you need is in the box. Provides better light than fluorescent daylight bulbs. I will definitely be ordering more!

M Wengerd
Excellent lighting!

Color is an important detail in life. If the light you have doesn’t make it visible you won’t see it. I am glad Waveform cares about color so that we get to see it. My flicker test is taking a slow motion video with my phone. Your lights perform well in my flicker test. Many others don’t. I would like to buy a hi cri panel light for an office enviroment.
