Color Rendering Index (CRI) describes how a light source makes the color of an object appear to human eyes and how well subtle variations in color shades are revealed. The CRI is a scale from 0 to 100 percent indicating how accurate a "given" light source is at rendering color when compared to a "reference" light source. The higher the CRI, the better the color rendering ability. Halogen is considered the “reference” light source and has a CRI of 100.
