Hi, I haven't posted for a while :-) I'm at 900 hours on my 90es, always at High Lamp. Subjectively the brightness drop feels similar to all my previous projectors (from sony, nec and optoma). 2D remains plenty bright and beautiful on my screen (1.0 gain, 10ft wide 2.35). While 3D is getting dim, but not enough of a difference to consider getting a new lamp or a new screen yet, my usage being 95% 2D anyway.
