I bought a replacement lamp for my Mitsubishi projector a couple of years back from Pureland Supply. I was really surprised that a generic replacement lamp hit 3,000 hours. I kept thinking I'd need to replace it and even ordered a spare last summer but this one is still going. I just reset the projector timer as it hit the 3,000 hour timer limit for the second time with this bulb! BTW, this is with the lamp mode set to normal, not saver mode which means it should only have lasted 2000-2500 hours.
