Proscenium opening is 30' x 16'. It is about 50-60' to the front of the proscenium from the light booth. It it another 20' or so to the back of the stage. Obviously we don't need a larger spotlight. I am considering the follow spots listed below. Altman Comet Lycian Midget II with 575 W bulb Lycian Midget II with 750 W bulb Lycian Midget with 1000 W bulb Maybe $400 difference in price between them. What would give the best bang for the buck?
