What does the color rendering index of a shadowless surgical light represent and what is a good value?

The ability of a light source to render color to an object is called color rendering, which is achieved by comparing the appearance of the object's color with that of a reference or benchmark light source of the same color temperature (incandescent or painted light). The spectral content of the light emitted by the light source to determine the color of light, but the same color of light can be many, a few or even just two monochromatic light waves longitudinally, the color rendering of each color is also very different. The same light color of the light source will have a different spectral composition, the spectral composition of the wider light source is more likely to provide better color rendering quality. When the spectrum of the light source is little or no object in the reference light source reflected in the main wave, the color will make the color to produce a significant color difference (color shift). The greater the degree of color shift, the poorer the color rendering of the light source for the color. Color rendering index coefficient (Kaufman) is still the definition of the light source color rendering evaluation of the general method.
