What is the expectations of a lamp brightness?
Most manufacturers rate their lamp life, not to failure, but to the point where the lamp is half as bright as it was when new.http://www.projectorreviews.com/advi...Brightness.php
I have never seen or read a review where you should expect to loose that much brightness in that short of amount of hours.
As for how bright is bright enough, Art at Projector Central throws a wrench in this by saying "the RS2 delivers over 300 ANSI lumens. This is still plenty of light to fill a 120" screen with great contrast and snap, again due to the latent strength of its contrast and color saturation." And this was the longest throw (farthest back) from the screen and in low lamp mode.
300 ANSI is 7.9 FL, that capital "Y" thing. And I suspect in a mancave. But 7.9! Thats acceptable? and presumably on a bulb with less then 100 hours.
The RS2 is rated at 600 ANSI, 10.4 FL. I wonder where I might begin to see a difference between 10.4 and 7.9, I don't think I would, but I expect those Lumens to be 10.9 to 7.9 at least till the half way mark.
As for SMX screens. I thought about getting one also but was talked out of it because of the light loss going through the material. Talk about being dim then.
