All of our strip lights require constant voltage. A constant voltage power supply is an electrical power source that regulates voltage to a constant level. In the case of TiGHT LED tape, a constant 24V would be required.

Yes it is! Color Rendering Index (CRI) is the measurement of how colors look under a light source when compared with sunlight. Having information on the CRI of a LED strip light is important because you want to make sure that the colors are being accurately represented by the light source. CRI is measured on a scale from 0-100. A CRI of 80+ is the industry-standard for most applications while a CRI of 90+ tends to be necessary for situations that need color accuracy.

LED chips are not all equal. The four digits represent the size of the chips in millimeters. For example, the 3014 chip is 3.0 mm X 1.4mm.

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 6500K. When getting close to 3000K, the light is noticeably warmer. On the other end of the spectrum, the lights have a blue-ish tint and cooler tone when nearing 6500K.

This is calculated by measuring the lumen output and then dividing that number by watts. For example, a strip that has a lumen output of 300lm/ft and a wattage draw of 3w/ft has an efficiency of 100lm/W.

This is a rating system that defines the ability of a product to be able to work in different environments. IP is an acronym "Ingress Protection". It is a measurement of the protection an item will have against solid objects (dust, sand, dirt, etc.) and liquids. An IP rating is comprised of 2 numbers. The first number refers to the protection against solid objects (dust, etc) and the second number refers to protection against liquids. So what is the difference between IP65, IP67, & IP68? The differences between commonly sold IP65, IP67, & IP68 strips are slight, but very important. IP65: Water resistant. “Protected against water jets from any angle” *Do NOT submerge IP65 LED lights, these are not waterproof. IP67: Water resistant plus. “Protected against the events of temporary submersion (10 minutes)” IP68: Waterproof “Protected against the events of permanent submersion up to 3 meters”

Yes, they can be cut to desired lengths.
