[QUOTE="Ben Lawrence, post: 203371, member: 391"] I have a projector with a Short Throw lens on it. It seems like I remember it being brighter when I had the standard lens mounted in a similarly lit room. Is there a loss in Lumens associated with using a short throw lens compared to a "standard" lens? [/QUOTE]
