What does CRI stand for?

CRI stands for Colour Rendering Index, also sometimes referred to as the Colour Rendition Index.

It is a quantitative measure of the ability of a light source to reproduce the colours of various objects faithfully in comparison with an ideal or natural light source e.g. daylight.

When is it important?

Light sources with a high CRI are desirable in colour critical applications such as photography or cinematography.

What are some potential CRI bandings for certain applications?

  • 70 is good for streetlights or general illumination such as floodlights
  • 80+ is required for nice quality lighting applications
  • 95+ is used for best colour clarity in Museums, and for skin tones etc.

Anything greater than 90 requires better, and more complex, driving and optics.
