Do Pico Projectors need replacement lasers / LEDs?

I'm not sure I understand the logic behind why this was closed; it sure seems like a real question to me (albeit very to-the-point). –  Shinrai Mar 2 '11 at 20:41

It not only appears to be a real question, it has real answers. Which rather implies that it can be reasonably answered in its current form. –  thursdaysgeek Mar 2 '11 at 21:51

In theory, yes. No bulb will last forever. In practice, no; pico projectors use LEDs, which have tens of thousands of hours of life. If everything else worked perfectly, that would mean the bulb could shine uninterrupted for two years straight. That's six years of life if used eight hours a day every day. In other words, the bulb will certainly outlive the device.

This review indicates that pico projectors use led or laser light sources and have a lamp life of 10,000-30,000 hours. Could there be premature failure? Probably.
