Question 1

Are your LED strips constant current or constant voltage?

Accepted Answer

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.

Question 2

What is CRI and is it important?

Accepted Answer

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.

Question 3

What is the difference between 3014 LEDs v 5050 LEDs?

Accepted Answer

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.

Question 4

What is color temperature (K) ?

Accepted Answer

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.

Question 5

What is luminous efficacy?

Accepted Answer

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.

Question 6

What is IP stand for?

Accepted Answer

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”

Question 7

Can TiGHT LED TAPE be cut?

Accepted Answer

Yes, they can be cut to desired lengths.
