Understanding the Color Rendering Index: A Comprehensive Guide to White Light Quality in Artificial Lighting

White light is a combination of different wavelengths

To understand the CRI color rendering index, we need a brief explanation of how sunlight is perceived as white.

Glass prisms are an easy experiment to visualize the composition of sunlight. It shows white light is a combination of different wavelengths in the electromagnetic spectrum.

 

To have white light from an artificial source, a mix of different emitted wavelengths is required. However, a close analysis of the white light of artificial lighting shows that not all white light is the same.
