The latest trend in hotlights seems to be clusters of CFLs, so not so
much heat any more. The other trend is LEDs but they are *really*
expensive for an equivalent amount of light.
My concern with CFLs is getting out of phase lighting, which can be a
problem if you want to shoot at higher shutter speeds than 1/30 second
(in NA, anyway, it might be different in OZ if the power cycles
different from here). I've heard of people having atrocious white
balance problems with LEDs (stage lights) because they are such very
narrow spectrum lights.

Out of phase issues with the CFLs: hmmm, I hadn't heard anything about
that, but it certainly sounds like a valid concern. I'd imagine that
would vary widely by CFL make and the amount of coating used in the tube.
Re LED stage lights: yes! I've had annoying problems with those myself.
But the ones that cause the big problems are the LED spots comprised of
alternating red, green and blue LED lamps that can be mixed by the
controller board to produce arbitrary colours.
The new LED arrays that are sold for video shooting use uniform matched
"white" LEDs and are apparently very close to traditional Flash WB.
