I have been looking at RPTVs for a few weeks now, and now I am thinking about a front projection. My only concern is the lamp life. I will use this as my "normal" tv, which consists of about 30% DVD's (weekend), 60% TV (watching stuff Tivo recorded for me), and 10% PS2..... The panasonic, under low power conditions, has a lamp life of 5000 hours, which if I were to use the system for say 50 hours a week tops (mostly on the weekend) I would get around 2 years of service. This would be acceptable, as the replacement lamps are $360 bucks. Now, from everybody's experience, is 50 hours a week about right? I calculated say 5 hours a day (when I get home from work). And say 12 hours a day on the weekends. This is of course if I am home, and not out hiking, etc. I am trying to think of worst case scenarios. Also, how long are bulbs usually available? Should I buy a replacement when I get the projector? Finally, this would be installed in my den, which has 1 source of light (a window to the back yard). Would using normal wood blinds be enough control of the light, or should I block out the light more? I know a lot of my questions are hard/impossible to answer, but I just wanted to hear other peoples experiences. Thanks a bunch... Kimo B.
