Not part of the official project but thought I'd add my findings.
My original lamp for my RS-50 lasted about 800 hours, at which point is was too dim to use.
My new lamp, an 003 series (with the flapper), has never seen high lamp mode, never been on for longer than 3 hours, and is used at low elevation.
My first 54 hours have been:
Color me extremely worried, as the recent trend to loose a few lux every few hours is the same as when my original bulb died.
At very minimum seeing this drop short of 100 hours is...worrisome, and is no doubt the same pattern my original bulb followed when new. I will continue to monitor and report my findings.
As a quick aside it's a pain because at 205 Lux this projector is simply *stunning*; why do these lamps have to be such a pain Edited by Grdinic - 8/1/12 at 9:56pm
