I have a job where we just swapped an epson 9700 for a JVC RS50, with each projector, lamps only seem to last 700-900 hours. This guy lives in a condo so the power may be flaky, he watches the thing 5-6 hours every night.

I was just wondering if anyone has had this before where lamps just don't last? The av system is plugged into Panamax, the projector has a power link kit attached to a little UPS that's just below the projector.
