Just flagging a useful link here. Hopefully I don't get "notified" by Mark...
Elite Projector Calculator This is one of the BEST projector calculators out there. Way more accurate than the ones at ProjectorCentral or the like.
Using it with the Epson 3010 and a 106", 1.79:1 (16:9) format, 1.0 gain screen and you have PLENTY of light to shoot a great image. The calculator shows 21.1 fL with the iris closed, and a massive 34.6 fL in Best Mode (low lamp). You want to usually target 12 fL - 16 fL in a fully darkened room, but 16 fL - 22 fL will allow for bulb dimming over time.
