How much is too much? I received my Panasonic AR100U projector back around the last week of March. In the ~7 weeks or so we've been using it, it already has over 150 hours of use on it, possibly closer to 200 (forgot to check last night after watching a flick).
It's not so much the actual hours I'm concerned about, it's the number of bulb strikes. Right now the only display devices in our house with DVD/BRD players are the living room TV and the projector. My 2-year old loves watching Elmo DVD's, Chipmunks, Pixar, etc. so my wife will put those on for him in the movie room while she's doing other stuff around the house. Makes life much easier because otherwise he follows her around whining and screaming all day. As such the projector bulb gets struck sometimes 15+ times per week.
Does that sound like a lot? Sometimes we might put his DVD on for him in the living room, but usually we're watching other stuff. And I'm not really keen on him having a TV in his room, perhaps because I never had my own TV until I was in college, or perhaps because I just don't want to buy another TV. Something about a 2-year old having his own TV in his room just doesn't seem right to me. I dunno, thoughts?
