I want a front projector. The problem is that the room that the FP would go in is bright. I can close some vertical blinds and reduce the light somewhat. I might be able to add some curtains but they would have to be acceptable for my wife. So, how would I go about determining the brightness I need? (My room is 16'x18' The throw will be 16', maybe closer if I can hang it from the ceiling.) I don't want to spend $1500 on a FP that I can't use until 9. Is there some kind of specialized equipment out there that measures lumens? My wife works in a facility that used to do some optics, they might have some stuff sitting on a shelf that they would let her bring home. I know that this is related to the screen. My plan is to show it on a specially painted wall (another thread) for awhile. I would rather spend the money on a better FP, and then move up to a nice screen.
