Go authentic! I replaced the bulb in my Sanyo after about 1400 hours (long story, but it was self inflicted thanks to my kids being "cold in the home theater" and cranking the heat with a vent above the projector!!!!... Oh wait, long story stopped.)
Anyway, I found a place online where you ship in your dead bulb (or pay a premium and then ship it in later) and they will take the bulb out of the casing and put a new one using "OEM" bulbs and send it back. Cost me like $100 shipped.
it isn't as bright, and it is leaning strong to the red spectrum, when the original for my Sanyo leaned towards blue. Contrast took a dump too.
I took the bulb to another guy's house (same Sanyo model)about 2 months ago and same result there, so it wasn't the projector.
