Frequently Asked Questions

Q: What are the top 4 comparing factors to look for before purchasing LED strip lights?

- Understand what your project needs, then compare lumen output, CCT, and CRI from strip to strip.
- Compare LED strip size and number of chips on the reel.
- Understand the wattage and voltage that the LED strip light uses.
- Make sure that the products have verifiable quality.

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 below 3000K, the light is noticeably warmer. On the other end of the spectrum, the lights have a blueish tint and cooler tone when passing 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: Do the UltraBrightTM Industrial Series strips need a heat sink?

Yes. This requires a heat sink to create the perfect environment for this LED strip to thrive in. Due to a higher heat output, it’s imperative that a heat sink is used with this strip.

Q: How many feet of Industrial LED strips can I run?

We recommend to run no longer than 1 full reel (9’ 10”) in series. After this distance, you will start to see a dimming of the LEDs near the end. This is called Voltage Drop. If you need to make longer runs, run in parallel from the power unit or attach an additional power unit.

Q: Why doesn’t the Industrial Series come in IP65?

This product is not available in an outdoor version (IP65) due to its higher heat output. We feel that enclosing this strip does not allow for proper heat dissipation and can theoretically lower the lifespan of the lights.

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

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]

    Posted by Anonymous on 18th Mar 2017

    This is the brightest LED strip I was able to find. I recommend it.

  4. Very bright and seem to work well

    Posted by Artyom S. on 1st Mar 2017

    The led strip is really consuming only 6.6W per foot while giving close to 9000 lumens per 10 ft, which is much better than the other strips I tried

  5. WOW

    Posted by Jeff K. on 18th Feb 2017

    When I was shopping LED's. I ran across Flex fire and I must say that the LEDs I bought we're very bright just what I was looking for. The people at the company are very helpful and want to make your project go very smoothly I would definitely recommend the LEDs and the company. Thank you very much for offering a good product and having a wonderful customer support team.

  6. Excellent product, prompt service, competitive pricing.

    Though I ordered "coming soon" utra bright LEDs, what was received was more than adequate. Created replacement for dual Circline kitchen fixture. 20% less power consumption, 10% more lumens and cool operation. Easy ordering process, prompt delivery and excellent packaging. Happy customer.

  7. Brightest LES strip I've used

    Posted by Kevin S. on 30th Jan 2017

    We purchased the warm white Industrial strip for a couple of tradeshow installations and the product performed beyond expectation. We couldn't be happier and these will be our go to lighting solution in the future.

  8. Always satisfied

    Posted by Anonymous on 23rd Jan 2017

    Have ordered this product and other items several times with no complaints, issues or concerns.

  9. The brightest led strip I could find

    Posted by Tom on 12th Jan 2017

    I was looking for a bright led strip to go into some custom task lamps. I looked every where until I found this one and it exceeded my expectations. This was my first led project and the tech support team answered all of my questions. If you need a bright led strip, stop looking elsewhere, this is the source.

  10. The Brightest Lights I Have Ever Seen

    Posted by PJ T. on 2nd Jan 2017

    This product is well made and is the brightest I have ever used on my projects. My clients were extremely happy with the results.

  11. Great!

    Posted by Kristen O. on 2nd Jan 2017

    Great product! Our UltraBright™ Industrial Series LED Strip Light was used on an induction heating machine.

  12. excellent leds

    Posted by Anonymous on 5th Dec 2016

    Bought these to light up one of my kiosks. The parts I have completed looks great really shows the colors of the products. They ran out of them beofre I can buy the quantity I needed, but was informed today that they will be back in stock by weeks end. GREAT!!

  13. Purchased as a test setup for a Green Screen Studio (it worked)

    Posted by Scott Singer on 17th Oct 2016

    Purchased as a test setup for a Green Screen Studio (it worked) The recommended height is 8' but my studio setup has a 10' or so height. I used two 16' strips side by side wired on separate switches. I mounted them to a 5" round aluminum tube so I could roll it and position it for the angle I needed. It is working, I am also adding a 8' single strip on both sides to help with the screening process also on a separate switch. I am running the lights with a Odyssey battery and a 45amp power converter (used in an RV) which will keep the battery charged and NOT CAUSE FLICKER which a camera can pick up. This is working extremely well.

  14. Great Product

    Posted by Jason Hannigan on 12th Oct 2016

    Works as advertised. The LEDs are high quality and super bright. I would definitely recommend them.

  15. Best leds and service in the market!

    Posted by Kevin McBride on 4th Oct 2016

    These flexfires are really terrific. Unbelievably bright and efficient. Their customer service is also unparalleled. Great company to work with!

  16. good product

    Everything was good.

  17. Right amount of light to backlight monitors on sit-stand desk

    Posted by Madeline Bechtold on 20th Sep 2016

    My husband wanted backlighting for his three monitors. He has a Jarvis 78" x 30" sit-stand desk, and that desk is already crammed with monitors, computers, and other gadgetry. So, we wanted a minimalist lighting solution that would travel up/down with the desk. We had already looked at other LED light strips and realized they wouldn't be bright enough, especially since my husband's desk sits next to a brown wall.

    FlexFireLEDs recommended a lighting configuration that included a 48" length of UltraBright™ Industrial Series Natural White LED Strip Light. I taped the LED strip into a Klus aluminum channel and velcroed the plastic channel brackets to the top back of the desk. A dimmer dimmer switch allows us to regulate the light throughput.

    My husband is very satisfied with the quality of our lighting configuration, and this LED strip is definitely bright enough and then some for what we're using it for. Thanks, FlexFireLEDs!

  18. Great for Under Cabinet Kitchen Application

    Posted by Amy in TN on 5th May 2016

    We tried some other LED strip lights and found them to be very dim, not nearly bright enough for task lighting under my kitchen cabinets. I searched the internet for bright, warm LED strip lights and found Flexfire! When I chatted with Leo about our application he warned me these lights are BRIGHT, "like see-them-from-the-space-station-bright"! That sounded good it us! We installed them on a 3-sided aluminum heat sink and placed them facing our backsplash so we could avoid the bright reflection in the granite. We also installed a dimmer on the switch so we could tame the brightness when we want. We LOVE how they work and look. With the indirect light, we get a lovely glow from the strip lights that's also bright enough to work by. These are worth every penny! Thank you, Leo for your help! We are very happy!

  19. Quality Bright Strip

    Posted by Nicholas on 14th Mar 2016

    Like everything there are pros and cons. However my overall impression was positive.

    (+) The strip has a high brightness.
    (+) The cut points are frequent with a small distances (important for spanning circles).
    (+) Documentation about (and comparing) the strips (including a lumen metric) is available.
    (+) Well presented and finished looking strip.

    (-) Soldering on the back of the strip means there is a bump (rise) under the strip at the solder point when installed.
    (-) Isolation of the solder joint underneath the strip is more challenging for various reasons when mounted on a conductive backing.
    (-) Polarity indicator marks need to be printed on the strip more frequently (currently several meters apart).

  20. Excellent light distribution

    Posted by Unknown on 26th Jul 2015

    Suited to the application of study lighting, easy to solder on cable

  21. Suited Nicely

    Posted by Unknown on 26th Jul 2015

    Very bright Excellent lumen's for application

  22. Fast Delivery

    Posted by Alex on 23rd Mar 2015

    Although I have not assembled the fixtures, they were shipped quickly.

  23. Let there be LIGHT!

    Posted by Robert Loundagin, Metrologist, Kirtland AFB, NM on 20th Mar 2015

    I purchased a foot of these wonder LEDs, so that I could perform a visibility test. I am engaged in a project that requires the LEDs to be visible outdoors, in the New Mexico sun. These will definitely do the job. In fact, you do not want to look directly at these lights, which will allow me to employ colored gels in front of them so that the different timers are easily differentiated by both the players and spectators. Installing them on a heat sink is also a very good idea of you are planning on running them full bore.

    They are by far the brightest LEDs I have found, and I do believe they will actually meet or exceed the rated lifespan. Numerous organizations have gone with the lowest cost LEDs they could acquire, which has resulted in them having to replace numerous sections as they fail so often and quickly. Some have reported failures before assembly was even completed.

  24. These really are bright!

    Posted by Jim in Soquel on 5th Dec 2014

    I am impressed with the brightness and flexibility of the strip. I stuck them onto a heat sink and the heat sink gets up to 135 degF, so if you just stick these to your cabinet, it might get too hot--be careful.
