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.
