Illumination
Typically, I find that they have 300W bulbs. Are there any that run brighter? --

Given that screen size varies, I need a measure of how much light leaves the projector. Home theatre seems to go up to around 2000 lumens with no problem. However, I cannot find the IMAX equivalent that would enable me to work on screen sizing.
