Actually, on the forums, people are abandoning the RS50 and 60 in favor of the 40 because the 40 is considerably brighter. I got 45 fL from an RS60 (same as the 50, but it uses only the best of the subassemblies used to make the 50… and it costs an additional $4000). But the only way to get that much light is to set Color Pallet to OFF which gives you completely uncorrected light from the projector… which gave a HUGE plus-cyan error. Any mode that’s reasonably close to Rec 709 would produce about 17 fL with a new lamp and 13 fL with 600 hours on a 1.0 gain screen that’s only 6 feet wide. I can’t even imagine how weak it would be on a 9 or 10 foot screen. You’d need a lot of gain (and all the problems that go with that) for any fairly large screen.
