In general terms, CRI is a measure of a light source's ability to show object colors realistically or naturally compared to a familiar reference source, either incandescent light or daylight.RI is calculated from the differences in the chromaticities of eight CIE standard color samples (CIE 1995) when illuminated by a light source and by a reference illuminant of the same correlated color temperature (CCT); the smaller the average difference in chromaticities, the higher the CRI.
