Tom, I'm not sure which "low light temperature lamps" you are referring to here.
It's my understanding that incandescent lamps, despite having a significantly
lower light temp than, say, cool-white NOs, have CRI at or near 100.
So if people opt for fluorescents over incandescents, or if they add in some fluorescents to a previously incandescent-only fixture, then it's for some other reason than CRI (e.g. operating cost, cooler tanks, esthetic, superstition, whatever's-on-hand, etc.).
I've read that we should try and think of CRI and light temp °K as uncorrelated.
PS: am I misremembering what I've read?
