UltraBright™ LED strip light FAQ:

Q: Which Power Supply do I need for my (x) feet of LEDs?

The length of LED strip lights of your project will determine the size of the power supply you need. View our Power Supply chart to find the exact LED power supply you need.

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 dropping below 3000K, the light is noticeably warmer. On the other end of the spectrum, the lights have a blue-ish tint and cooler tone when rising above 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: I am looking at the UltraBright™ series for task lighting in my office, but I am unsure which will be better, the 12V Design Series or the 24V Architectural Series?

The 24V Architectural Series is the best strip to use for larger projects that require a high level of lighting and loner run lengths. One of its advantages is the ability to run them in a continuous series of 32ft 10in (2 reels). Every environment is different so please feel free to contact our design team for further recommendations. The 12V Design Series is another excellent option that offers very bright output but have a slightly lower intensity at 469 lumens per foot. This option works well for smaller areas that also require task lighting.

Q: Is there an outdoor option?

Yes, we do carry a water resistant Outdoor UltraBright™ Architectural Series Natural White LED strip light.

Q: What is the maximum run length of the UltraBright™ Architectural Series lights before voltage drop?

Maximum continuous string of lighting in series: 32ft 10in (10m). Longer connections are possible in parallel with the correct power unit.

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

Q: What is a 3014 SMD LED chip?

3014 SMD (Surface Mounted Diode) represents the size of the LED chips on the strip. A 3014 SMD chip measures at 3.0mm x 1.4mm. Click here for more information on LED chip sizes.

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.

  1. Graet Product

    Posted by Mike P. on 27th Dec 2016

    Top of the line Quality Product and customer service is even better.

  2. Homeowner do it yourself

    Posted by Anonymous on 25th Dec 2016

    I am attempting under counter lighting in my wife kitchen. Went to the flex fire web site and found my products, wow so many to choose from but made my choices. I went a step further and sent my choices to flexfire in an email asking for suggestions. The response back was prompt and they provided additional insight and it changed some of my picks and saved me money and headaches later. I received what I ordered and it arrived before the estimated delivery date. I would order from flexfire again.

  3. Wow These look fantastic.

    Posted by Anonymous on 9th Dec 2016

    I installed these lights in my kitchen as both task lights and accent lights under the counters. Unlike many of the lights you find online - these as so much higher quality and bright. We were even able to change our overall lighting choice since these can also serve as task lights. They were not difficult to install.

  4. Knowledgeable and Dependable

    Posted by Mark S. on 5th Dec 2016

    This is the second project I've used Flexfire LEDs for. They are super-bright, which is great because I use them to light up my stained glass artworks from behind. The people at Flexfire always pair my LEDs with the right transformer and dimmer units, and they ship my order within a day of my placing the final order. Mark Stine

  5. high quality build, super bright and strong adhesive.

    Posted by Yukinori Endo on 23rd Nov 2016

    I have been specifying LED's in my products for years now and I have discovered flexfire after hearing from another lighting designer. I am very happy with the product after using them in a recent restaurant that required UL listed LED strips. These strips are very well made, they are sturdy and the adhesive is strong. I would recommend them highly.

  6. The BEST product I have installed!!!

    Posted by Vlad Kasko on 22nd Nov 2016

    I am very happy and my customers are super excited the 24volt architectural led strips are superior compared to some product that is on the market. And when I had a little issue the customer service was super! These guys will take care of you . I got good indetect light even though the ceiling was 18ft high and talk about smooth lighting with the small LEDs I recommend this product to everyone.

  7. Very bright and easy to install

    Posted by JMath on 22nd Nov 2016

    This set was recommended by the tech support because of its features. The run of lights goes around the perimeter of our living room and the perimeter of a hallway, a total of 87 feet. The wiring was divided into 3 separate runs. The 24v capacity provided the end LED's to be as bright as the beginning. At full brightness, the room is almost as bright as daylight. I am running them at about 30% with the Single Color Touch Series Dimmer to provide a nice background light. Installation was easy with cut points approximately every 2" and soldering points at those locations. I recommend a no residue flux for placing a bead at the soldering point. I also recommend to tin the wire before attachment. Peel the backing away from the solder point as well. One end comes with a 4" wire attached so if you are using the full 16 foot, it is quick to string sets together (do not exceed the recommended length). I placed mine in crown molding 8" from the ceiling on aluminum straight rod, 1/8 * 5/8" for a heat sink. So far, no glitches and very satisfied.

  8. Sports car daytime running lights

    Posted by Joshua Wright on 7th Nov 2016

    Super bright and very high quality! Adaptable size to fit perfectly where I wanted them!

  9. New house needed the best

    Posted by Thomas Leever on 31st Oct 2016

    We built our dream house and no small part was played by your excellent products. We used mostly the warm white in the wall sconces and on tops of the kitchen cabinets. They really highlight the different cabinet heights.

  10. Easy planning, purchasing and installation

    Posted by Gregory Sprowls on 28th Oct 2016

    I knew what I wanted to do, but couldn't find a how-to online. I had a chat session on the flexfire site and they walked me through step-by-step for what I needed to accomplish the job. As a result I had the right tools, equipment And plans for my installation, and it looks amazing!

  11. They work great

    Posted by Michael Hardin on 22nd Oct 2016

    I use these lights inside and outside of sign cabinets. I am very pleased with how bright and dependable they are..

    Posted by Don Philippbar on 16th Oct 2016

  13. Very nice lighting!

    Posted by George Reitsma on 15th Oct 2016

    I use the LED strips for under cabinet lighting and to light the ceiling from the crown molding. Good quality, and nice natural white. Much better than the strips from HD.

  15. A great product

    Posted by Sally Cutler on 5th Oct 2016

    We replaced 18 old fluorescent tubes mounted in soffits in a master bathroom remodel with the Architectural Series Natural White LED Strip Lights. The lighting is dramatically improved - clean, bright room illumination. Our contractor found the installation straightforward and will be using Flexfire LED products in future projects, as will I. The staff at Flexfire were extremely helpful and responsive, a delight to work with.

  16. Ultrabright NW led

    Posted by John Litarowich on 4th Oct 2016

    I purchased the ultrabright NW led's for under cabinet lighting in my kitchen along with a dimmer switch. What a difference it made compared to the Fluorescent lights I previously had. The Ultrabright led's are much brighter and give off a more natural light. Flexfire helped me with the design layout and ordering the necessary components. These lights are far superior to ones I purchased at a local home center and are easy to install. I would highly recommend these lights.

  17. Easy, Bright, and Beautiful!

    Posted by Dan Beard on 3rd Oct 2016

    Perfect for adding fantastic light under kitchen cabinets!

  18. Nothing short of Amazing!!!!

    Posted by Wayne Saddler on 1st Oct 2016

    After doing extensive research into LED strip lighting and giving Flex Fire products a try. I have concluded they are amazing. I purchased this product for a church kitchen project for above and under cabinets, Absolutely the best led strip lighting on the market, Everyone who has seen them agrees. So then I made a 2nd purchase for my kitchen at home, with the same result. Outstanding!!! The staff were very helpful with assisting my purchase on line, fast friendly service. Why buy anywhere else.

  19. Great product. Very helpful staff.

    Posted by Brian Cox on 14th Sep 2016

    Got remote-dimmable led strips. Very difficult to solder. Takes patience and experience, but a total of 3' of led mounted in 2 torchieres is enough for 20x20 room. Site is so informative. Staff is very responsive and helpful.

  20. Under cabinet Lights

    Posted by Unknown on 11th Feb 2016

    I bought these to replace 14x 25W Xenon lights under my cabinets. I couldn't stand those Xenon lights. They kept breaking after only about 6 months of use. It was so irritating to have to replace them... and they were expensive. One roll and my countertops have never been so bright. Coupled with a Lutron dimmer and a 96W Zurik transformer and it's like I have a whole new kitchen. I highly recommend these lights.

    I will say they do put out some heat after a little while. Others have mentioned they are cool to the touch. They are initially, but they do heat up. Mine are in aluminum channels and I would say the channels get to about 85-90 degrees F. Though, they are way cooler than those crappy Xenon fixtures they replaced!

    One recommendation... If you do solder the wires on, make sure you use flux. I tried soldering without it, and it was extremely frustrating!

  21. Great service and info

    Posted by R.J. Steckel on 3rd Jan 2016

    Have not installed at this writing. Will respond after installation. Products look good so far! Thanks

  22. Great color

    Posted by John on 17th Dec 2015

    The strips are the color described and very bright. Time will tell on quality. The only thing wrong with the strips is the 3M tape on the back. It will not hold the ends of the strips down. I had to get some tabs that nailed down to hold the strip ends from popping up.

  23. 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.

  24. Great product, was a little put off by the collateral information

    Posted by Brian on 30th Nov 2015

    The lights are fantastic, I'm using them to light a marquee in an arcade game. We used cheap LED's in the prototype and they were really dim. Flexfire Ultrabright Architectural work great.
    However, their first impressions could be better. When I opened the package, there was a nice envelope and a few other pieces of paper. For the price of these LED's, I was expecting some sort of a welcome packet or something telling me how awesome these are going to be and how great Flexfire is or a thank you for buying these. But it was all information about how you can't return these things. Multiple pages of nicely printed stuff about how you can't return them. Is there that much of a problem with people returning stuff that you need a special envelope and that's the first thing you want your customer to read?
    Love the lights, but the packaging/delivery experience could be better.
