The color rendering is the appearance of the light source to the natural color of the object. That is, the degree of color fidelity, commonly known as the "color rendering index" (Ra).

The International Lighting Committee (CIE) set the color index of sunlight as 100, total 15 test colors, and ranging them from R1-R15. When comparing a light source with a specified reference source, the index value of 100 is the best.

How to choose the right Color rendering index for different applications?
