The Color Rendition Index
The color rendition index, is a measure of the ability of a light source to reproduce the colors of various objects being lit by the source. It is a method devised by the International Commission on
Illumination. The best possible rendition of colors is specified by a color rendition index of one hundred, while the very poorest rendition is specified by a color rendition index of zero. For a source like a low pressure sodium vapor lamp, which is monochromatic, the color rendition index is nearly zero but for a source like an incandescent light
bulb, which emits essentially black body radiation, it is nearly one hundred. The color rendition index is measured by comparing the color rendering of the test source to that of a perfect source which is generally a black body radiator, except for sources with color temperatures above 5000K, in which case a simulated daylight (e.g. D65) is used. For example, a standard cool white fluorescent lamp will have a color rendition index......
