You'd be surprised: Since I did NOT have to worry about the Bat Signal actually projecting the Bat emblem image, I just worked to make sure it looked good lit up as a prop. I used a simple photography light socket and 12-inch reflector set with a 150 Watt PAR 38 flood bulb screwed into the socket.what did you use for a light source
I believe you are correct. One ton for the searchlight, then. Still far too hefty for a non-profit student stage production performed in school or on a community theater stage. LOL!The person who quoted you "three tons" was including the weight of the generator. See The Fort MacArthur Museum's searchlight page: it quotes the combined weight (of both the searchlight and generator trailers) as 6,000 lbs. Since the generator is a fairly hefty piece of equipment powered by a 6-cylinder gasoline engine, I'd guess it makes up probably 2/3 or more of that total.
