Exactly. Its always better to have more light than needed. ND filters are relatively cheap and if the bulbs dims 40% who cares? And one can use the best unity gain fabrics if room considerations are right or sane mild gain screens if they are not. . Remember these new projectors aren't for those with 2 chairs in front of the screen and can't get by with a retroreflective screen set up. I do feel the days of very expensive say $30 to $35K street price consumer projectors are over.
First 4k is coming really fast and whether one likes it, and idiots stop trying to convince themselves that who needs it 1080p is enough at my seating distance (and true if they sit in the bleachers in left field and just like the cry WTF overkill, give me 720p or give me death, I don't need a 1080p projector, whatever. And just like CDs have gone away to a large extent, content will be delivered over the internet and rented rather than owned and those with the right servers will sooner or later be able to get the same feeds as commercial theaters. Film distribution is over and disc distribution will die out too. This will all lead to the golden age of film production, with the film being digitally distributed in the highest 4K quality to consumers willing to pay a premium and to masses at a lower quality but still digitally. and its all green. No plastic DVD boxes and DVDs, no cutting down of trees to make storage racks, no rediculous DVD and Bluray servers at high prices like the K scope. Nope. Buy a server like the Redray for $1450 or built into a under $5K0 projector server combo for the big, really big, home theaters and with the coming of toy $4K projectors like the very good toy 1080p projectors out there. and Red with no middle man will likely have in a year a consumer projector, 4K laser driven, built in DCI server for say anout $15K. But they dsaid $10K. they said $1000 for Redray and it came in at $1450. They said $10K for the projector there and no mark my word it will be around $15K unless they figure out a way to do 4K with a 4K lens and cut the server out. You are in the wrong forum is $15K is too rich for your blood.
