WHAT is the Color Rendering Capacity ?
* The Color Rendering Capacity is a measure of the color
rendering quality of light sources,
---devised for dealing with the concern of
whether a given sort of light source is capable of
---rendering a great number of widely
different colors.
* The Color Rendering Capacity of a light source gives
information about the upper limit for
---the number of the colors that can be
rendered by that source with one unit luminous flux.
* The greater the Color Rendering Capacity, the larger the number
of the colors that can be
---vividly rendered by that source. With
the Color Rendering Capacity, people can tell exactly
---which one is the best among several
sorts of light sources and which one is the worst
---according to the number of the colors
that can be vividly rendered by the light source.
