Its pretty well known that Epson will replace the bulb for you during the 2-year warranty if you call and ask. If you are smart about usage (not a lot of unnecessary power cycles), I would expect a realistic 1000hrs out of a bulb on these. If you use high-altitude (extra cooling fan) and/or the ECO setting (lower light output), you will get longer. I don't think anyone has seen the 4k hours that Epson advertised originally.
