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.
