@ iaw4: No, there is no such thing that you sdescribe. There will be HEAT GENERATION and HEAT DISSIPATTION out of this red laser + LED light engine PJ as well. If not, you would quickly fry the internal organs, qand you would not want that, correct? The XJ-A series is actually pretty loud for fan exhaust, this XJ-M series model is much less so.

@ William Dakota: I am now covering a 24.5-foot wide 2.2:1 aspect ratio gray screen out of a 7000 ANSI lumen projector. You will never be able to cover a 30-ft width out of a 3000 or 2500 ANSI lumen PJ, not even close to it.
