It does sound like a lot, but with how much the TV in our house is on (at least 8 hours a day), 20K hours goes by a whole lot quicker! I was mostly curious as to what happens with a laser projector at that point.\n\nI will admit that I was a bit confused when OP was concerned about lamp replacement but then mentioned laser projectors!\n\n\nRight there with you. Laser PJ is a great concept and it's nice to see that JVC nailed it pretty good with the NZ3. I'd be curious to see one of the models I linked earlier. It's a very interesting concept.
