Assuming you mean the electronic flash: That's a xenon flash tube. It's designed to put out a bright, but very BRIEF, flash of light. If you put enough circuitry behind it you could turn it into a strobe light; run that at a fast enough and -- if you don't overheat the flashtube, which wasn't designed for this application -- it might approach being usable as a flashlight.A lot of work for dubious odds of a not-very-good result. I wouldn't bother. There are better solutions.
