For a local theatre company I'm building a few special-effects props, including a palm-mounted (likely on a glove) unit that produces a bright flash of light, enough to momentarily overpower the stage lighting.
I've picked up a 980 lumen LED that runs at 3 amps and 3-4.2 volts, and I'm wondering if I need anything more complicated for switching the LED than a high-enough power transistor?
Others I've spoken with have only been experienced with constant-lighting applications, so recommended switchable LED drivers, which I haven't found yet. Any suggestions?
(though not strictly necessary, it'll have a microcontroller for precise timing of the flash. Though a 555 timer might be more prudent if the LED takes too much current)
