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]

  1. Strip lights

    Posted by Anonymous on 11th Dec 2017

    Flexfire LEDs products are good I have no complain. However,support needs to be improved in answering customer phone calls. After placing the order they did not returning phone calls or emails in time. Need to call many times a day. This issue did not happen before I placed the order. They picked up the phone every single time for questions and answers.

  2. great service

    Posted by David B. on 9th Dec 2017

    prompt and great quality so far

  3. Ultra Bright Industrial Lights is an understatement

    Posted by Gerald J. on 4th Dec 2017

    These lights are so bright they're hard to look at directly. I wouldn't have believed they would be so bright. They generate a bit of heat, so be careful if placing them close together side by side.

  4. Effective, Efficient, Easy

    Posted by Brian S. on 20th Nov 2017

    All lights from Flexfire are easy to use and these are no different ; just calculate the power supply needed and solder away!

  5. nice n bright

    Posted by sean w. on 27th Oct 2017

    working great for led tail lights on my 66 suburban

  6. LED lighting

    Posted by Anonymous on 9th Oct 2017

    I liked the ease of attaching the power source to the lighting strip and the lighting was very bright. Looking at purchasing it for my next project that is coming up in a few months.

  7. Excellent lights!

    Posted by Michael R. on 16th Sep 2017

    Easy to install!

  8. Bright Efficient LED Strip

    Posted by Edward M. on 3rd Sep 2017

    This is a well made strip. The reliability is TBD. The connection points don't leave enough space for a well reinforced joint with adhesive lined shrink tube.

  9. UltraBright Industrial LED - Highest lumens output per Watt.

    Posted by Anonymous on 15th Aug 2017

    Project was hotel office environment. Compared Industrial, Architectural, and High CRI series. Also compared energy used, lumens output, TCO (overall costs over the service life of material), and cosmetic factors. For this particular project the optimum choice was found to be the Industrial Series in conjuction with a dimmer for full control, all powered by UPS devices. FlexFire staff provided invaluable help, support, information and advice throughout the process. Thank you FlexFire. Excellent customer service.

  10. Great product & support

    Posted by Chris B. on 13th Aug 2017

    This product exceeded my expectations on quality and brightness. I had some technical questions about the product use and limitations and they went above and beyond to make sure I got complete answers to my questions.

  11. UltraBright is right!

    Posted by Thomas B. on 19th Jul 2017

    Bought these for a specialty fixture I’m building. Using the 12v version and the give me the highest output I’ve found from LED strips at that voltage, even with just using 8 AA batteries. Will be buying more soon.

  12. Great results

    Posted by Brad M. on 10th Jul 2017

    It took about 4 hours to install, we had to drill several holes for our project. Everything went together nicely. I wish the clear cover was more of a bulb for heat dissipation but they seem to be fine. The light was very bright just how we imagined. Very pleased with results. I also wish they had a greater selection of control boxes via wifi/Bluetooth/app. We are working towards a smart home.

  13. Still the best supplier

    Posted by Earle W. on 26th Jun 2017

    I have bought a number of smaller lighting systems from Flexfire for installation in customer sites. This is the first I've bought for my own use in my woodworking shop (industrial series). I mounted a 9'-6" strip on an equal length of 1 x 1 x 1/8 aluminum angle. This hangs over my woodworking bench such that I can evenly adjust the height through a pulley system and one cord. This allows me to vary the position of the light based on need. I'm getting old, and the need is always for more light. I chose this company a few years back because of their superb service. They continue to be the only company I know of with this level of commitment to the needs of the Customer.

  14. These"Industrial" style lights are the real deal!

    Posted by Terry B. on 3rd Jun 2017

    These are so bright and of such good quality, I'm proud to have these quality LED Strips in my custom install that won't fail in a short while like the cheap ones from Amazon. Definitely buying some more of these next project that needs some serious bright quality lighting. Anthony

  15. Super bright and easy to use

    Posted by Kyle C. on 2nd Jun 2017

    These LED's are super bright and exactly what I was looking for. Love the modular design aspect allowing me form and mount it in many different ways.

  16. Great lights

    Posted by Anonymous on 23rd May 2017

  17. Excellent LED

    Posted by Carlo B. on 9th May 2017

    Excellent LED strip, performs as advertised.

  18. good lights Very bright

    Posted by Anonymous on 8th May 2017

    bought LED strips from Flex Fire after cheap ones from amazon kept going yellow. the coating on the amazon strips to make them water proof goes yellow and the ones from Flexfire does not have the coating and does not go yellow. i bought the Industrial series and they are about twice as bright as 5050 strips from amazon.

  19. boat light

    Posted by Anonymous on 8th May 2017

    replaced fluoros in custom fittings with your leds and very happy with the light colour and intensity.i tried other strip leds and didnt like the results.will definitely use and recommend flex fire leds

  20. Machine Mill Task Light

    Posted by Anonymous on 30th Apr 2017

    I spent a great deal of time looking for a task light which would light up the work area of a new milling machine. I could find no commercially available lighting that would do the job. Finally I decided to look at LED strips. We had previously worked with FlexFIre to light up our over cabinet space in our kitchen.I called and discussed what I was looking for with FlexFire and received great advice. I was able to put together a lighting solution that was perfect for what I wanted. The Ultrabright Industrial LED strips provided a very intense light over a very small space. This was critical since I was working with an area that was about 4 x 6”. Now that the light is installed I could not be happier. It is exactly what I was looking for. Thank you FlexFire.

  21. Things to remember !!!

    Posted by Anonymous on 11th Apr 2017

    Price was reasonable, delivery was quick. Unfortunately... I did not realise the lights came as a strip with no on off controller. Make sure you remember to order all components with the help of their customer service.....I just ordered online and neglected to check if it came with an on/off switch. other than that the service was good..

  22. Super bright led strip

    Posted by Anonymous on 24th Mar 2017

I am planning on buying more for sure

  23. Good Stuff

    Posted by Mark S. on 24th Mar 2017

    Used them to back light the letters on a sign for Pax East. You could see it clear across the convention center.

  24. Brightest LED strip

    Posted by Anonymous on 18th Mar 2017
