I'm lighting a 25ft stage next week and there are some power concerns so I'm going to be using two 1.2kW HMI Pars to light the stage from near the back of the room, one on either side about 45ยบ to the stage. I'm wondering that kind of kick I'm going to get out of a 1.2 par going through a 42x42 silk armed out from its lollipop. Will I lose too much of the HMI's punch from say, 30 feet away? Would a frame of 216 or 416 be better than the silk? This will be to supplement the room's existing lighting and to nicely fill the talent on stage.
