I have one scene in a very small location (not really any room for C-stands, etc.). There is a lighting bar with 4 spots for medium base (household type) lights with a recommended maximum of 100W per bulb.
I've found a lot of 250W-500W bulbs specifically for film use, but there's not that much...
PM me if you have this set and want to sell. If you're in the Los Angeles area I can meet you in person.

I've used it on a few short films, but I'm at the point where I'd rather hire a sound guy than do it all myself. The Micover slipcover is amazing at getting rid of wind noise. A test showing the advantage over the deadcat is here...
