I am a vocal and unrepentant projector fanatic. I think projectors represent the best value in home entertainment, and wish more people would embrace the awesome as I have (for over 10 years now).
However, projectors aren’t without drawbacks, and the UHP lamps in nearly all of them are a big one. Hot, expensive, and not particularly long lasting, UHP lamp replacement is often cited as one of the biggest annoyances of projector ownership. The alternative, LED lighting, has mostly just been found in uber-high-end projectors, and inexpensive wee little projectors.
But not anymore.
