Thankfully my average seems to be about 250 hrs/yr on my bulb (FPJ1) since I only use it for movies.
I'm almost 500 hrs into my RS1x and i still have to use a 4x ND filter on my 96" high power. Otherwise the thing is blindingly bright and makes black levels seem as if they were from a cheap DLP projector.
I'm using normal lamp (low). I'm pretty sure i could light up a 133" neutral gain screen with this thing and not feel it lacked brightness, we'll see down the road though. But so far so good.
If anything it kind of makes me regret i got an RS1x instead of an RS2 or RS2 clone for about the same price, since i would probably still have brightness to spare, but i'd get better contrast.
I'm wondering if people that are having these brightness drops turn it on/off a lot.
Personally, if i turn on the projector, it stays on for the rest of the day i watch anything on it. (sometimes up to 10 hrs+) I don't know how much truth there is to repeat on/off cycles dimming the light bulbs faster since i can't really do an experiment, but so far brightness seems to have dropped to what i think should be within spec. (it's too bright with out the 4x ND filter on my HP, and i'm @D65)
