The colour rendering index (CRI) also sometimes referred to as the (colour rendition index), 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 (daylight). Light sources with a high CRI are desirable in colour-critical applications such as photography or cinematography and are also important in retail applications. The CRI does not bear any reference to the colour temperature (or CCT) of the light and this is normally also advised within the datasheet.

As an indicator below are some potential CRI (from 1 to 100) bandings for certain applications

CRI of 70 is ok for streetlights or general illumination such as floodlights.

CRI of 80+ is required for nice quality lighting applications

CRI 0f 0ver 95 is used for best colour clarity for Museums, skin tones etc

A CRI of greater than 90 requires better and more complex driving and optics.
