I have the HT1100 and the lamp has about 1270 hours on it. To my eyes the picture has dimmed significantly. I know the rating is for 2000 hours but I'm starting to feel like it's almost time to swap out that original lamp with a new replacement. Before going down that road (and I have a replacement sitting in a box ready to go) I have a few questions that perhaps those of you with more experience than I can address.
1. Rated lamp life: How realistic is this number coming from the manufacturer? 2000 hours sounds good but if the picture is dim at 1200 plus hours, getting to 2000 before replacing the lamp would be seriously painful.
2. What are the signs that a lamp is ready to be changed - short of a total failure? I'm running the PJ on "normal" so I'm squeezing every lumin I can out of it. I don't see any flicker issues, it's just a very dull picture.
3. I realize that all PJs have some issue re: lamps. With the HT1100 rated at 2000 hours and lamp replacements at $420 each - how does this compare with other PJs.
4. It's starting to look as though, based on my viewing habits, that I'm going to be going through 2 lamps a year. Although in the first month and during install, more stress (on and off) was the rule vs. now since it's final installation.
I don't have a way to measure the actual brightness of the image but the dim picture I have now is starting to drive me nuts. I'm willing to make a change but the hassle factor, and uncertainty about changing it at 1270 hours vs 2000 has stopped me from making the swap.
So, I am very interested in how others here base their decision on what point to pull a lamp and replace with a new one.
Thanks in advance for your feedback.
