The Dell 1850 takes a bare bulb listed here as 725-BBDO, supplied without a housing for fitting into the one already in your projector. No wattage or rated-hours figure is published for this part, so we've kept the listing to what's confirmed: fit, part number and housing compatibility.
This bulb is also referenced as M39M7 on some records, describing the same part. Since this is a bare bulb rather than a module, you'll need to fit it into your current housing yourself - if that housing is cracked or the socket is scorched, a module version is worth considering instead.

Common questions
Is 'Dell1850' a typo or a different model from the 1850?
It's the same Dell 1850 projector, simply written without a space in some records rather than being a separate model. This bulb fits either way the projector happens to be labelled.
Does M39M7 replace 725-BBDO, or are they the same part?
They're the same bulb rather than one code replacing the other over time - both 725-BBDO and M39M7 are used for this identical part across different records and listings.
Why are watts and hours missing from this listing?
Those figures aren't published for the 725-BBDO, so rather than state an unconfirmed number we've left them out. The part number, fit and housing type are all confirmed as shown above.
How do I remove the old bulb from the Dell 1850's housing?
The bulb is usually held in the housing by two small screws and a connector clip, both accessible once the housing is out of the projector. Support the housing while removing the screws so the bulb doesn't drop out unexpectedly.
What's a sensible way to check I'm buying the correct lamp?
Match the part number printed inside your projector's lamp door, if visible, against 725-BBDO or its alternative code M39M7. If neither number appears, confirming the projector model against the Dell 1850 is the next best check.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
