Whats the lowest Kelvin with 95+ Cri?

If you actually use an amber light or say red light indeed you don’t see colors on packages or flowers, etc because those are colored lights not white lights, but with E21 R9080 2000K white light I can see colors just fine, greens, blues, yellows, oranges, reds, violets. no problems.

I prefer the 519a… but only you can decided which one You prefer for your application.

both are High CRI, and both work better to check the meat on a BBQ in the dark, than Low CRI Cool White.

the two dots on the spectrum plot give a pretty good visual idea of the differences in color temp and tint duv. It is up to individual preference whether you like the CCT that is closer to a Candle, or closer to an Incandescent.
