I have decided to take the leap and buy a projector. My first choice is the Sanyo PLV-Z1. But I may spend a few extra bucks and get the Panasonic PT-L300U. On projectorcentral.com I see both get about 2000 hours of bulb life. I can do all the calculations I want as far as how long I will use the projector, or how many days a week I will use it but in the end it's a total guess. What do some of you get for bulb life compared to the advertised bulb life? Also, how long did it take you to accumulate that many hours. Maybe this is a dumb question, but I just want to know some real-world numbers. I only see myself watching about 1 movie a week and 2 to 4 hours a week of gaming on it. I did some quick figuring (at 10 hours of use per week), and that came up to just short of 4 years (200 weeks) for 2000 hours of bulb life. Can I really expect it to last that long?
