I can't quite articulate why, but when I ordered the replacement bulb for my InFocus X2, I wasn't absolutely sure I was ordering the correct bulb. It is not that the sight was unclear necessarily, I just had the feeling that there may have been conflicting information. For example, another projector that supposedly uses the same OEM lamp was directed to a different replacement part with a slightly different cost. Oh, well. I wish I could be more specific, but you can't ask me to remember details like that for more than a day or so. Good luck with your business and thanks for the help.
