"Lightning" effect on stage - any tips for equipment?

If you want a realistic lighting effect you can't really beat the Martin Atomic 3000 strobe. It'll cost you a bit to hire but it's one of the few strobes that will actually flash on command. Provided you use it in 4 channel mode, the Atomic has a bunch of pre-programmed effects, one of which is lightning and another is random flashing. If you've got spare capacity in your desk don't bother with the remote controller, just run DMX to the light. As far as timing goes, bear in mind that lightning rarely flashes at the same time that you hear thunder. You can feasibly have a 3 or more second delay before the audio triggers and it will look natural (indeed if they are cued together it looks a little too theatrical). If the script calls for the storm to be getting closer you can progressively reduce the delay. Most people in an audience will understand what's going on, at least subconsciously. Also, the temptation is to use open white for lightning, I'd suggest using a light blue gel as it looks more realistic. Talk to Matrix Productions (if you're in Perth) about getting an Atomic 3000.
