I have been trying to make a DIY fast strobe light. I am fairly new to LED's though.
My requirements is to have a very fast optical sample of falling raindrops. basically to photograph rain so that the drops are visible individually and not show up as a streak in my photograph.
In average conditions, I find a normal flash to work quite well. But the problem is the lifetime. I know that a normal flash lasts for somewhere well into 50k or 100k flashes. The typical flash time is in around 30 – 100 microseconds. But if I wanted to leave it unattended to continuously take photos, say every minute, the flash lifetime will probably run out quick.
I have come across the LED strobes which use LED's instead of flashes for the purpose.
I wanted to know if its practically possible to achieve a comparable light output using LED's.? ( I have a feeling its not possible )
Since the intended purpose will need short bursts of light. If I use high power LED's and overdrive it but reduce the time interval when it is on to somewhere like 10 microseconds, will it work without blowing out the LED ?
I appreciate everyone's view. Thank you.
