I am wanting to build an LED strobe for photography work - the requirements are that the pulse duration be about 2-5ms, and have serious light output. Back a few years ago when I was looking into it, a crapload of individual bright white LEDs could do the job, but even overdriving them 10-20x the build just became impractical size wise. Fast-forward to the modern times where high-wattage COB modules exist. I have done some looking around but can't find much info on the behavior of the drivers for these. While I assume the AC powered chips are unsuitable for my needs, I have found some 100W units that are still 10vDC. Could these be driven with PWM and overdriven?
