Product Description

UltraBright™ Slim Series LED Strip Light - Thinnest LED strip light

1/8'' wide strip
3 Meter Reel (9ft 10in) 


The Slim Series is an ultra-thin (3.5mm wide) strip light that is outfitted with extremely bright LED chips and a strong adhesive backing. It is one of the thinnest LED strip lights on the market. Sometimes referred to as "LED tape lights," the flexible design of LED strips allows for bright lighting almost any space you can imagine. These strips are great for providing elegant, discreet lighting and are commonly used by architects and lighting designers in professional installations.

IMPORTANT: Because of the small surface area, the strip should be attached to a heat sink like aluminum or another heat dissipating material to make sure the strip stays within a healthy operating temperature.

Frequently Asked Questions:

Q: Do you have solderless connectors for the slim series?

No, we do not. We recommend soldering with a very steady hand! 

Q: What is the product warranty?

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 decreasing from 3000K, the light is noticeably warmer. On the other end of the spectrum, the lights have a blue-ish 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: 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: 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: 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.
