What is the lifetime for projection bulbs?
DLP, LCD and LCOS rear projection sets have bulbs that may eventually have to be replaced. They lose brightness gradually over time, but then fail totally. Manufacturers claim anywhere from 2,000 to 8,000 hours to failure. That upper number may be optimistic — 2,000 to 4,000 hours seems more realistic. A few sets have a “low power” brightness setting that gives a dimmer picture but extends bulb life. Currently, common replacement bulb cost runs $200 to $400, though some bulbs are more. You might be able to replace a bulb yourself (check the manual). Otherwise figure in an extra $200 to $400 for the labor charge. Stores often offer an extended warranty which includes bulb replacement.
