WebKirchhoff’s Law states that a body that radiates strongly at some wavelength also absorbs radiation strongly at the same wavelength. Therefore an ideal blackbody radiator is both a perfect absorber and emitter of radiation. Many thermal sources, such as the sun, a flame, an incandescent light bulb, the Earth, approximate blackbody radiators. WebIf there is no change in appearance, the light source is given a CRI of 100 by definition. From 2000K to 5000K, the reference source is the Black Body Radiator and above 5000K, it is an agreed upon form of daylight. Incandescent bulbs have a CRI rating of 100, yet are far from ideal for color rendering and matching. Why?
