Seven projectors in Dell's M-series share a lamp position with Nobo's X22P: the M209X, M210X, M409MX, M409WX, M409X, M410HD and M410X. The 311-8529 module is built for all eight, combining a 165-watt bulb with its housing at a 3000-hour rating, so the whole unit drops in as one piece.
This same lamp has been catalogued under several references, including 468-8976, 725-10112 and GW905, alongside the combined listing 311-8529 / 725-10112. Whichever number appears on your current housing, it points to this module, and since it's a full module rather than a bare bulb, no separate housing purchase is needed.

Common questions
Why does one lamp cover both Dell and Nobo projectors?
Nobo's X22P and Dell's M-series models share the same internal lamp design, so a single module, the 311-8529, was built to fit both brands' housings.
I've seen this listed as 725-10112 - is that different?
No, 725-10112 is an alternative reference for the same 311-8529 module, and you may also see it combined as 311-8529 / 725-10112 on some documentation.
What does GW905 refer to?
GW905 is another code used for this identical lamp module, alongside 468-8976 and 725-10112. All the codes shown on this listing describe one and the same part.
Does the M-series module include the housing?
Yes, this is a full module, so the 165-watt bulb and its housing arrive as one assembly rather than a bulb to fit inside an existing carrier.
How many Dell models actually take this lamp?
Seven Dell M-series models take it - the M209X, M210X, M409MX, M409WX, M409X, M410HD and M410X - alongside the Nobo X22P, making eight compatible projectors in total for this module.
