High Colour Rendering Index (CRI)

High Colour Rendering Index

Colour Rendering Index (CRI or CIE Ra) is an average between R1 and R8, with a scale of 0 to 100, and is an indicator of how well the light source replicates standardized daylight. The Ra of Kyocera’s LED modules is 97, a very high number in the LED industry.  The remaining special colour rendering indices (R9 through R15) which indicate primary colours and colours of skin, are also very high.
