CRI is a measure of a light source's ability to accurately portray the color of an object, material, or skin tone on which it is shining. CRI ranges from 0 to 100, with the sun representing the baseline CRI value of 100%.
|All colors clearly separatable|
|Some colors look the same|
|Can't distinguish most colors|
CRI is determined with a test procedure using eight color samples. The light is compared to a control light and the average differences measured are subtracted from 100.
The smaller the average difference, the higher the CRI.
Ultimately the higher the CRI the more pure the light source.
80 CRI is great for indoor lighting and 70+ CRI works for a warehouse or industrial facility.
