BTW,  you can get LEDs that are designed specifically for flash applications.  They can handle high peak currents,  have decent color spectra,  and/or fast rise/fall times.  There are also LED driver chips made for flash applications.

Hi Mark,

Yes, I am certain that you can, but they are designed for
use in cell phone cameras, and other small digital cameras.

Their primary purpose is to make a blindingly bright burst
of white light to allow the camera to see.  If they are a
little slow to start up, and have an illumination hang at
the end, the camera won't care in the slightest... kind of
like the old magnesium flash bulbs.

I don't expect that they would make a suitable substitute
for an EG&G strobe lamp.
