Does anyone know the persistence times of the phosphors used in typical white LEDs? I built a strobe circuit a few years back, when ultrabright red was the newest thing, and was thinking of a newer version with white LEDs. I'm afraid that the white ones may not turn off fast enough, though, due to the phosphor continuing to glow after the current stops.
I guess I could use separate red, green, and blue LEDs, or even one of those nice packages with multiple chips in it, but it would be easier if I could get away with using white.
