Four Benq ultra short throw projectors, the MW842UST, MW843UST, MX842UST and MX843UST, take this lamp as a bare bulb under 5J.JCA05.001. Sold without a housing, it is meant to fit inside a casing that is already in place, so only the bulb itself is exchanged. No wattage or lamp life figure is published for this part, so neither is claimed here.
A module version of 5J.JCA05.001 covers a wider set of ultra short throw projectors, including these four plus others, and includes a new housing for anyone whose current casing is damaged. This bare listing suits the narrower group of four models above where the housing itself is fine. We hold one code for this lamp, so there is nothing further to check the number against.

Common questions
Which four projectors does this bare bulb fit?
The MW842UST, MW843UST, MX842UST and MX843UST. All four share the same ultra short throw lamp housing, so this bare bulb code covers each of them.
Is a housing included with this part?
No, this is the bulb only, for fitting inside a housing that is already in your projector. A module version with a new housing is listed separately and covers a broader set of models.
How do I fit this bulb into one of the four listed projectors?
Let the projector cool, open the housing as described in your model's manual, remove the old bulb by its base, and set this one in the same position before closing the housing again.
What are the visible signs that this lamp needs replacing?
A dimmer image, flickering, or a lamp warning shown on screen are the usual signs. No lamp life figure is published for this part, so these signs are the practical guide rather than an hours count.
Is there an alternative part number for this bare bulb?
We list a single reference, 5J.JCA05.001, for this lamp, used across the four ultra short throw models named above, so there is no second number to check it against.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
