What is Correlated Color Temperature (CCT)?

Correlated color temperature is the term used by technical professionals to refer to color temperature. CCT is a unit of measurement indicating the color spectrum—and therefore the warmness or coolness—of a light source.

How High Does the Kelvin Scale Go?

Correlated color temperature ranges from 1,000 – 10,000 on the Kelvin scale. Warmer, more red/yellow colors land on the lower end of the scale, while cooler, blue light has a higher Kelvin temperature.
