Sign Terminology

Color Temperature (CCT)

CCT is a term used for white LEDs to determine how warm or cool the LEDs are and is expressed in degrees Kevin (K). Lower values like 3000K indicate a soft incandescent light color. Bluer tone LEDs are usually above 7000K. The whitest part of the color spectrum that causes the least amount of color shift is between 5000-6000K.
