I've seen this floating around, wee bit off. 8000 hours tops (thats with minimal off/on).

8,000 is what the manufacturers mention, with most exceeding 10k from the little searching I just did.
regardless if its 80 or 8, its still not an issue when buying a tv set or projector. If you cant afford a fuggin $200.00 bulb every 5 to 7 years, then how the hell can you afford a 400.00 console and 60.00 games?
A dlp tv would last me to 6 to 8 years at 8,000 hours, and Id get a new one 2 to 3 years after I purchased it anyways so no bulb problem here. Surely some of you dont have the same tv you got 8 years ago. My bad, *some* of you were only 8 years old 8 years ago. I keep forgetting the ages around here
Shit in the last 11 years(when I got into home theatre hardcore), Ive gone thru 4 tv's(2 of them HD) and a projector.
Noone I know who likes games and movies holds onto a tv for more than 4 to 5 years. With progression comes time to buy new toys
I need to check the site that said it was 80,000 hours, maybe I read it wrong?
Nope, I didnt read it wrong..

LIFESPAN
DLP manufacturers list the backlight bulb hours at around 80,000 hours. What's more, this bulb can be replaced for as little as $200 in some cases. Certain DLP TV displays require a technician to change their bulbs, and this will cost you more than the lamp itself. In other cases, though, the DLP is configured in a way that makes it easy for a layperson to replace burned-out bulbs. It all depends on the make and model of your DLP.
And, since DLP is a mirror and light technology, once the bulb is replaced, the DLP should perform as well as it did when it was brand new.
Plasma, by contrast, uses a small electric pulse for each pixel to excite the rare natural gases argon, neon, and xenon (a k a "phosphors") to produce the color information and light. As electrons excite the phosphors, oxygen atoms dissipate. These rare gases actually have a life and fade over time. Manufacturers of plasma have estimated the life of these phosphors to be about 60,000 hours. The life of the plasma display itself is usually determined by half-life of the phosphors. So at 30,000 hours the phosphors will be at their half-life, and the viewer will be seeing an image that has half the brightness capability that it did when originally purchased. This should be a good point at which to consider its life over. The gases in plasma TVs cannot be replaced. There is no phenomenon of "pumping" new gases into a plasma display.
Advantage: DLP
Im sure the dlp tv's have a low lamp mode like projectors do. that alone would prolong the life of the bulb by a significant amount, and I can guarantee that Most owners do not use it because it darkens the picture, and most people live a bright picture.
Ive calibrated many a tv for people and they hate how dark it is afterwards. I guess the dont like lifelike pictures and instead of watching it how the directors intended, theyd rather crank up the contrast and black level. Makes me sick
