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 15-year warranty on most 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.
