Now let’s take a look at the two light sources we said at the beginning:
▲ Warm white CCT=3061K, it can be seen from the figure that the SDCM between it and the standard light source is within 5 SDCM, which is SDCM<5.
▲ Greenish warm white CCT=3078K, which is very different from the above 3061K color temperature value.
The SDCM between it and the standard 3000K is already outside 5 SDCM, which is SDCM>7, and the color temperature deviation is too large. There is already a color difference between them.
