5811118082-SOT is a 220W bare lamp rated for 4,000 hours, made specifically for two Optoma projectors: the W304M and the X304M. As a bare bulb, it is designed to be transferred into the housing already fitted inside your projector rather than arriving as a boxed unit.
This part has just one listed compatibility pairing, so if your projector is a W304M or X304M, the fit is straightforward without needing to cross-reference several models. Fit it by opening your existing housing, swapping the old bulb for this one, and reassembling; no separate cage or frame is included since the housing stays with your projector.

Common questions
What are the wattage and rated hours for 5811118082-SOT?
This lamp runs at 220W with a rated life of 4,000 hours, and both of those figures apply equally to the two projectors it supports, the Optoma W304M and the X304M, with no variation between the pair.
Does 5811118082-SOT fit any projectors beyond the W304M and X304M?
No, this listing covers only those two Optoma models, the W304M and X304M, so compatibility here is narrower than some of our other lamps that span a dozen or more projectors.
For the W304M or X304M, does 5811118082-SOT arrive framed or loose?
Loose. It is a bare bulb rather than a module, so you reuse your projector's existing housing and fit only the new lamp inside it, with no separate cage or frame included in the box.
Should the stock image on the 5811118082-SOT page worry me?
No. No specific photograph is available for this part, so a placeholder image is used instead; the listed specification, wattage and fit remain accurate regardless of which image appears on the page.
What signs suggest my projector's lamp needs replacing?
Dimmer output, a shift in colour balance, or a lamp warning on screen are typical signs it is time to fit a new bulb in your W304M or X304M.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
