Just wanted to update everyone on my high-hour HD1000U.. I had posted up a while back once I had hit 10,000 hours on it and purchased a new bulb for it.. Well, we've now hit 20,000 hours and still going. I got another 10,000 hours on the most recent bulb, which is still going, but has become a bit dim. I just placed an order for bulb #3 today, so we'll see if we can hit 30,000 hours with that one.
This projector is used as the main television in our house and is on for at least 12-16 hours a day, as my significant other works swing shift compared to me and is usually watching it in the morning while I'm at work.. So, its on for 8 hours in the morning, then usually another 8 hours at night!
After hitting 20,000 hours on this unit, I'm thoroughly convinced that bulb longevity is maximized by reducing the number of heat cycles. Its not how long it stays on, its how often it gets cycled. So, despite the hours, the projector is still going strong. The color wheel is starting to whine a bit, but we'll put up with it for a while longer.
What a fantastic projector... I think I've gotten my money's worth out of it.
