FULL SPECTRUM:

​

A light whose spectrum closely mimics that of natural daylight.

​

The term “full spectrum light” gets used frequently, and oftentimes erroneously, as there is no single agreed upon definition.

​

A light whose spectrum closely mimics that of natural daylight.

​

Specifically, it should have a CRI (Color Rendering Index) of 95 or better, and a color temperature of 6500K.

​

Most vendors use 85CRI and 5000K as the minimum for full spectrum.
