Looking for some lamps (CFL and/or LED) and, not wanting Warm
White/2700K, nor Daylight, I have been searching with other obvious terms.
Have found that sometimes Cool White means 3000K. Sometimes 4200K, or
5000K, or 6000K or 6500K. Or some other in-between temperature. Seems to
start at 2701K and go to infinity!
I had hoped that 6000/6500K might commonly be "Daylight", 2700K "Warm
White" and maybe 3500 to 5000K could be "Cool White" - but no chance.

And does anyone list CRI in the lamp specifications? Other than a few
fluorescents, hardly ever.

Fl tubes normally do. CFLs I've seen it in small print on the box, sometimes in a format like '827' meaning 80-90% CRI 2700K CCT.
