What is Kelvin Color Temperature?

Color Temperature is expressed in degrees Kelvin(K). For example, northern blue sky is approximately 6700 degrees Kelvin - the same as our full-spectrum Vi-Tek 93® Plus. Fluorescent lamps with lower color temperatures look red; fluorescents with higher color temperatures look blue.

What is the Color Rendering Index (CRI)?

The sun is the ultimate light source by which all light sources are compared. Natural sunlight at noon from a color rendering standpoint is said to be at 100. The closer a lamp gets to a CRI of 100 the sharper colors are rendered, the better contrast is established and the “ease of seeing” creates a much more comfortable environment.
