värvieraldusindeks
Värvieraldusindeks, often abbreviated as CRI, is a measure used to describe the ability of a light source to reveal the colors of various objects being illuminated by it. It quantifies how accurately the perceived color of an object under a specific light source compares to its perceived color under a reference illuminant, typically natural daylight or a blackbody radiator of similar color temperature.
A CRI value is given on a scale of 0 to 100, where 100 represents the ideal
The CRI is calculated by comparing the spectral power distribution of the light source with that of
