Hello all you brilliant techies. I have had my projector for my media room for about 7 years now, a Viewsonic PJ510, and the bulb life is 2-4 thousand hours depending on whisper mode or regular. I only have about 600 hours on it and I was wondering if the bulb diminishes in brightness/power with age rather than just use. I feel like the videos are not as brilliant as I once thought they were. I don't know if it is my imagination, as I have a HD TV and blu-ray in another room and find that my eyes are now comparing. Does the bulb diminish with age as well as use? That is my question. Thank you for considering an answer for me. cheers

Lamps do gradually diminish in output but it shouldn't be that noticeable after 600 hours. Lamps and internal components, such as lenses or mirrors, can also accumulate dust which will make them look dim. Take care when cleaning them as they scratch easily. Maybe the HDTV in the other room is too bright and needs to be calibrated. In any event, a projector will never be as bright as an LCD TV.

Thanks Scarybob, I will get my lens cleaner from my glasses and have a go at it. I will be careful and perhaps calibrate the LCD TV. I appreciate your reply and look forward to a few more years and wait for the HD projectors to come down in price. Thanks again

When I said take care I was making an understatement. I don't recommend using any type standard cleaner or standard cloths. Brushes, cloths or fluids designed for cleaning camera lenses should be OK. Mirrors and lenses are especially sensitive to scratches and require a special technique. Wipe with a clean cloth once, in one direction only and discard used cloths.
