It's amazing that, despite their generally poor color rendering,

maybe color rendering isn't that important compared to seeing what you're
doing.The eye/brain manages to compensate,excpet under low light levels.

It _is_ important in photography, where color accuracy is of considerably
greater significance than "seeing what you're doing".


Besides, tungsten lighting (2700K or 3200K) isn't all that "color
accurate"
itself.

In this context, that's not really correct. Any continuous-spectrum lighting
source that's free of holes or peaks in its spectrum inherently has
"perfect" rendering. All it needs is a filter (or RGB gain adjustment) to
give correct rendering for any color temperature.

CFLs generally have discontinuous spectra, and vary widely in rendering
accuracy. The photographic CFLs in my Lowell ego lights are rated at 93%,
which is fairly good.
