What is CRI?

CRI stands for Colour Rendering Index and in simple terms, based on a figure from 0 to 100; it is the measurement of the ability of light sources to accurately reproduce colours in comparison to a standard reference source. The higher the CRI rating the better the light source is at accurately reproducing every colour of the spectrum. There should be no excessive excess or loss of any colour generated from the lamp in order that illuminated objects appear naturally. With LED lighting, look for an absolute minimum CRI figure of 80 but to recreate the quality of light achieved by a halogen or incandescent lamp you need CRI levels of, at the very least, 90 but 95 is preferable.
