Color Rendering Index CRI

The Color Rendering Index (CRI) is a measure of how faithfully a test light source can render a set of 15 defined colors when compared to a natural light source. The more balanced the rendering results are, the higher the CRI will be. If all test colors render equal to a tungsten halogen lamp the CRI would be 100.

A typical entertainment RGB led lighting fixture (Chroma-Q™ Color Block™) has a CRI of 67. The MSR575 lamp fitted into many of the professional entertainment moving lights have a CRI of 70. Such are the advances in control technology that the latest Chroma-Q RGBA fixture (Color Force™) has a CRI of 92.
