The right speed color wheel can do a lot to get rid of the rainbow effect, and admittedly my W1070 is 2000 lumen, but it is as bright of a home projector as I've seen, it can be seen pretty well in a lit room, and I'm throwing around 140" - 150", and could easily see this going beyond 180" without looking shabby...

BTW, which anime convention are you referring to?

Otakuthon. Our experience with 2300-2700 lumen single-chip DLP projectors on 180" screens was... suboptimal. They were 4:3 projectors and screens, though. The limitations of what we've got have stopped us from trying anything larger with our 4300 lumen projectors. Our new Epsons might be able to push it a bit bigger, though... If memory serves, we are looking at getting some 16:9 screens in the 200-220ish range this year, we'll see.

I've got 290" screens in my main events room, but we don't buy the projectors for those, we rent big 14,000 lumen units that take two people to move :P

There's this wall of price, for projector brightness. Once you hit around the 4000-5000 lumen range, the price stops increasing linearly and jumps up. For example, I can do 4200 lumen for under a thousand bucks, but to double that brightness it might cost me ten times more.
