I am involved with a low-budget theater group (thespians) that have an old, old follow spot with a monster 1000W lamp without the proper reflector.
I have a friend who is a wizard with lighting systems. He said that 410W MR16 lamp will put out as much light as that old 1000W _and_ have a built-in reflector. But it's 82V, not 120V. So my first thought was a transformer. But I'm not having much luck finding a 120V-82V 500VA transformer. My next thought was a half-wave rectifier. Since the lamp doesn't really care what the voltage is - just the power dissipation - I calculations are 410W @ 82V = 16.4 ohms 16.4 ohms @ 115V = 807W half-wave rectify a 807W AC load should result in 403W. Perfect! The "snag" is I don't know how the lighting dimmer is going to react to a half-wave rectified load. Any thoughts? Oh, and I last drove to the theater in my 240D.
