Product Description

UltraBright™ High CRI Series (93+) LED Strip Light 


Not all light is created equal. One may assume just because the color temperature, wattage, and size is the same between two different bulbs they are equal, right? Not necessarily true. Let's discuss light quality.

The Color Rendering Index (CRI), also known by some as color accuracy, is a term of measurement of how natural the light given off by a source looks in comparison to the sun. Have you ever purchased a red towel or dress in the store and when you try it on at home or wear it outside in the sun it looks different? This is because the CRI is different between the two light sources. High CRI LEDs will show an objects true pure and vibrant color.

The highest CRI is 100 (like the sun). Most LED strip lights have a very low CRI (60 - 70). Our UltraBright™ High CRI LED strip lights have a minimum 93 CRI and have been measured up to 96 (all other Flexfire LEDs strip lights have a CRI of over 80).

Also, these natural white strips are extremely bright, emitting over 450 lumen per foot.

This photo demonstrates the difference between CRIs, given everything else being equal.

This product was initially designed to be used for professional photographers and the film industry. It is quickly becoming integrated in high end grocery product and produce displays, art galleries and museums, donut and pastry racks, in retail locations and dressing rooms as well as under residential cabinets and cupboards. Also, our lights meet the requirements for California Title 24 which requires high CRI in new lighting installations.

Frequently Asked Questions

Q: What is the importance of UL Listed?

UL is an acronym for the Underwriters Laboratories. They are an independent product safety certification organization. A good summary used by UL is, "a not-for-profit organization dedicated to public safety." This means you can install these LEDs in commercial spaces, industrial applications, and in your home with peace of mind.

Q: What is the product warranty?

We’re so happy with the quality of our product, we offer a 5-year warranty on all of our LED strips to all of our clients. The warranty on power supplies ranges from 2 to 7 years which is model dependent.

Q: What is the lifespan of your strip lights?

Our lights have been rigorously tested and have an expected lifespan of 50,000 hours before dropping to 70% luminosity. This means that if you were to use your lights 12 hours a day, every day, the lights would be expected to last longer than 10 years. Even after that time has elapsed, the lights will maintain a brightness of 70%. Higher-output strips require a heat sink to reach the expected lifespan and beyond.

Q: What is color temperature?

The color of light can be quantified by referring to its color temperature. White light is measured in Kelvins (K). Most white lights fall in a spectrum between 1800K and 6200K. When getting close to 3000K, the light is noticeably warmer. On the other end of the spectrum, the lights have a blue-ish tint and cooler tone when nearing 6500K.

Q: Which color temperature should I choose?

Choosing the correct color temperature lights for your project is very important, and as important as the brightness you choose. Consider the look and feel you want your project to have. What other color lights will be present? What material and color are the materials you wish to light? We can help you choose!

Q:What are lumens (lm)?

This is a quantifiable amount of light produced by an LED strip or other light-producing product. This is one way we can measure light output.

Q: What is a 3020 SMD LED chip?

3020 SMD (Surface Mounted Diode) represents the size of the LED chips on the strip. A 3020 SMD chip measures at 3.0mm x 2.0mm. Click here for more information on LED chip sizes.

Q: Can I create a photography / video panel with your LED strips?

Yes. The UltraBright™ strips have been used in many photography and video lighting projects. The slim nature of the strip and the adhesive backing make it very easy to create your own custom light panel. Check out this video review of the UltraBright™ High CRI strip being used in a light panel.

Q: Which power source do you need for my project?

LED Strip Light Power Usage Calculator - Which power supply do I need?

Q: What do I need to turn on my lights?

To turn on LED strips, you will need to connect to a LED power supply. For connecting strips to the power supply we recommend soldering to make the strongest connections. Another option is to use our solderless connectors, which is a faster and easier way to install LED strips.

Q: How do I mount the lights?

The 3M double sided adhesive that is found on the back of the LED strip allows you to install them in most locations. Be sure to thoroughly clean the surface to remove all dust and particulate matter before mounting the strip. Certain surfaces may require you to take additional measures to secure the strips lights into place. Feel free to call us with any questions.

Q: Can I cut the strips myself?

Yes, LED strips are made to be cut to your desired length. Using sharp scissors, you can cut the strip every few inches (on a line that's marked after every third LED).

Q:Wow these are bright! What do I do if I want to dim my LED strip lights?

All LED strip lights are dimmable. The LED strips can be dimmed either through our dimmers [PWM dimming], or by a Lutron wall dimmer

To dim the lights you have two options:

  1. If you plan to dim your LED strips using a hardwired Lutron wall dimmer, you need a Zurik dimmable driver. This driver itself will be dimmed from the Lutron switch.

  2. If you do not plan to dim the lights from a hardwired wall dimmer and want to dim them with one of our dimmers, you will need a non-dimmable LED driver [Mean Well or Flexfire LEDs Brand]

  1. Well made and good color rendering

    Posted by Alan on 13th Dec 2015

    I'm very happy with the performance of these lights, although I wish they were a little less expensive.

    I used the strip lights to make a small prototype photography panel light. I was able to make a 2.5" x 4" light which turned out to be quite bright (~900 lumens) and generates it very little heat. I used an X-Rite color checker to visual assess the CRI. The lights seem to render color very accurately. When I have more time, I will take photographs of the color checker with this light and compare it to photos taken with my studio strobes.

  2. They're What I Was Hoping For

    Posted by Unknown on 9th Dec 2015

    Beautiful colors, plenty bright, easy to install, low power; who could ask for more.

  3. Good quality light

    Posted by Matthias on 28th Sep 2015

    I used this product to replace an LED strip with a CRI of 70. What a difference it makes! I am using it for indirect illumination of the ceiling in several parts of the house. The UltraBright High CRI emits a pleasant light that makes skin tones look natural. With the low CRI strip I had before, people looked sickly grey-green. I'm also using this product for task lighting in the kitchen. The shadows look softer compared to the old strip I had because there are more LEDs per foot than on the old product.

  4. They are great

    Posted by Unknown on 14th May 2015

    If you peel the back off and stick them direct, you may never be able to reuse the LED strip, so I used these with some double sided strips for hanging things on a wall.

    Flexfire should sell these, they make the install very easy.

  5. very nice

    Posted by Unknown on 25th Feb 2015

    worked as advertised. so much better than fluorescent under cabs.

  6. Best lights I have had!

    Posted by CarolK on 28th Oct 2014

    I just bought these lights and used them in 2 shows and they are fabulous. I had them on pipe about my booth and used 3 strands. They light an entire 10x10 and my lights were the whitest in the whole show. Everyone else looked yellow by comparison.

    Absolutely worth the price! I sold more in this show than I have done since 2007!!!! And I know the lights had a lot to do with it.

    I did solder on my lights with the connector, which can be a little flimsy, and they worked great.

    When one orders items on-line it is usually somewhat of a "crap-shoot". Here is an exception. These LED strips were wonderful. Not just the light output, but the "QUALITY" of the light itself. I am very pleased and will incorporate these in my line of lighting devices.

  8. Very bright and amazing colour quality!

    Posted by Elektrika - Electrical services and design on 17th Aug 2014

    I've recently purchased this LED strip for undercabinet lighting for one of my customers.
    It's very bright (150 - 70 lumens/sqft on the counter space!) The colour quality is very good. I've been long looking for high CRI led strips and finally found Flexfire. If only they weren't so expensive...

    Personal advice for DIY: Try to limit strip lengtht to 2 - 2,5m per feed. Feeding entire 5m with one cable produces too much of a voltage drop within the strip resulting in heat losses.

  9. I love the product. I just wish it were less expensive.

    Posted by Unknown on 26th Jun 2014

    With other LEDs I always felt the room was dark even if there was plenty of light, and I couldn't match the colors of my clothes. These give off a clean bright light that makes you feel good. It is bright without being that bright blue that makes you feel sick. And I can now tell the difference between very dark blue and black. I can think of all kinds of places around the house and shop where I would love to use this if only I could afford it.

  10. High CRI - Critical to successful lighting

    Posted by Steve Root on 30th Apr 2014

    I decided to replace old undercabinet lighting in my kitchen. It was a flourescent light, 18 or 20 inches in length. The &#@$ thing buzzed loudly. Now for some reason the industry is convinced that the big thing with LEDs is that they save energy and therefore money. That is nice, but the savings over flourescent, in my 9 cents a KWH location, are not that huge. The huge advantage (aside from being quiet) is the quality of the light. It is like washing away 20 years of grime. For $30 (half the cost of a Home Depot LED under cabinet light with a CRI of 80), the ultrabright strip light with >90 CRI gives me jewelry store lighting quality under my cabinet. One downside, however, is that it makes all the other lighting in my kitchen look pallid. I am so happy with the high CRI lighting that I am now upgrading lights all over the kitchen. This will be an easy and not very expensive home improvement. I look for the marketing emphasis on LEDs to shift to the quality of the light in the next two years (so far, the light quality marketing focus seems aimed at retail locations). Halogen is dead meat.
