NettetCRI R9 is a very important metric because many light sources will be lacking in red content, but this fact will be hidden due to the averaging out of CRI calculations which do not include R9. As the chart below shows, an light source can actually perform quite well with the first 8 test color samples, scoring quite well for R1-R8. NettetCCT is defined in degrees Kelvin; a warm light is around 2700K, moving to neutral white at around 4000K, and to cool white, at 5000K or more.
