Sorry, you bought a "Compatible" lamp, which means that it WASN'T! Read the listing description, it actually says "Compatible". That is a red flag right there. Do not depend on the seller to tell you it is or isn't compatible. I've seen plenty of ads where the seller said a lamp was compatible with a list of projectors and a quick check of the list showed that he was lying.
A generic lamp can work for a few hundred hours and quit. Why? Because the electrical parameters may be JUST in the envelope for the projector to work, but after a short period of time, it is no longer "compatible"
So, bottom line, by trying to save a few bucks, you actually WASTED your money. These forums are full of reports from people who did the same as you and regretted it. I know of people who bought "compatible" lamps for their projectors and the lamps burned considerably hotter than the OEM lamps and burned the optics.
