If lamps cost you 25 cents to 50 cents an hour, it's still worth it, eh? Projectors are ( IMHO ) the Lamborghini's of the video display world. And if your tires on your Lamborghini wore out at 30K miles instead of the rated 50K miles, would you sell it and get a VW Jetta? No, you would get a new set of tires.
I agree that lamp life estimates are just that...estimates. But no one can argue that the RS40's (and others from that model year) had SIGNIFICANT lamp issues that go beyond the normal variance. With a 3000 hour rating, I would only expect 1500-2000 useable hours....and I would be quite happy with that.
My AVS B Stock with 002 lamp failed at 450 hours (projector was 8 months old)....thats pretty bad and in line with what most people here have experienced with the 002 lamps. Fortunately, AVS is very good to their customers and got me a replacement 003 lamp very quickly with no issue. That lamp is only 150 hours old. Has it dimmed a bit, yep, but what I would consider normal. I am hesitant to measure as I'd just rather not know if I can't tell by watching! Problem is if the new one fails at under 500 hours, that would be two lamps with the same issue and if I can't get another free replacement, then I am about $400 into the cost of a new projector that has reliable lamp life. That's unacceptable would mean a new lamp every 8-12 months. If I can even get 1000-1500 usable hours, that's at least acceptable....still not great though.
I just hate the feeling that JVC offloaded these B stocks knowing full well the issues with the lamps and figured at worse they'd give out one free replacement and then tell you to buy a new PJ if you didn't like the lamp life. Just reeks of total contempt for the customer. Now if the 003's are really the fix, I'll be happy with my RS40 until 4k and/or LED/laser light sources are affordable and commonplace. I really don't feel anything else puts out the same PQ at this price and going back to an IRIS would suck now that I am so used to the native "miles deep" contrast and black level of the JVC.
The Lamborghini comparison is a bit unfair because there are cheaper projectors with better lamp life, and more expensive TV's with no lamps to blow. Not to mention that kind of car is not a stock item, such as a projector Plus projectors are become more and more common in the home ( not to mention YEARS of business use), where I doubt Lamborghini is increasing their sales much.
Bottom line, I don't think you can argue that The RS40's don't (hopefully we can say didn't) have an issue with their lamps dying way too early.
