Which Sony model ?

I often wonder if operating conditions (temp, voltage, on/off cycles, etc) may make a difference or if its pre-ordained how long a bulb will last regardless of the abuse it may receive in terms of dirty filters, high temperatures, or other factors. So far I have 1260 hours on a three year old bulb, but who knows what tomorrow will bring.

I got 941 hours (grrr) out of my first lamp in an Optoma. Second lamp is at something like 2400 hours and still purring albeit a little dimmer. Same operating conditions and usage patterns for both lamps. I think it's a crapshoot.

Guys, as I explained above, lamp manu. rated their lamp, "Average Rated Life in hours" (their terms) and this means at the rated life 50% of the lamps are still burning and 50% are burnt out. This is a fact.
