I can try this next time with a CFL bulb if you wish. I'd imagine I will have some challenge because of the time lag for coming on full strength and some after glow after it's turned off. As to LED, I'm concerned about the spectura VC papers/filters require. It'll be an interesting experiment that I don't mind doing myself.
Somewhere on APUG, there was a post from someone who made his own "cold head" with LED matrix.... I remember he used two different colors and ultra-violet.
