ABSTRACT:
In evaluating whiteness of light from a light source or a luminaire, whiteness W is given by the following equation,in-line-formulae description="In-line Formulae" end="lead"?W=−5.3C+100,in-line-formulae description="In-line Formulae" end="tail"?wherein chroma C is determined by the CIE 1997 Interim Color Appearance Model (Simple Version).
