The character of objects' colors determines the source of light color rendering. According to the international normative standards,the color rendering index of reference illuminant is 100. Higher the color rendering index is, less the anamorphose will be. That is a good quality in terms of photosource. The high efficiency of an operating lamp is closely related to this aspect.
