BenQ replaced the color wheel and insisted that the reason the color wheel failed was because I was using a lamp from Pureland supply!! I think at this point I'm just as well off using a cheap lamp from China!!
2 Lamps exploding in a row and I very highly suspect an electrical issue in the projector, ballast, fans, or a voltage problem in the outlet. Did you hook a volt meter that can record voltage over time to ensure you have clean voltage, and I might also suggest a UPS that does AVR...
The "CyberPower CP800AVR AVR Series UPS 800VA 450W Compact" as one example...
I'm far from an expert at the internal workings of the lamp parts in projectors (know more about the lens parts and color wheel), but it seems like a heat or electrical issue with your particular unit.
Now I could be wrong, but I've been using projectors for 15 years, and have friends with projectors and many other people that I know, plus read all these forums for years and years.
Other than some defective lamp designs like v1 and v2 JVC lamps, and some Epson lamp issues in the past, having 2 bulbs explode in a row is EXTREMELY rare and I'd suspect something going on.
