Sold as bulb only, 5811118543-SVV is built to sit inside the housing already fitted to a Vivitek D865W or DW866. We record just these two projectors against this particular bare listing, narrower than the module version of the same part, which also covers the D86GAB and DX864.
Because this is a bare bulb, the fit depends entirely on your existing housing being sound; a cracked cage or clouded reflector will not be solved by this part. If either is a concern, the module version of 5811118543-SVV pairs the same bulb with new housing hardware instead.

Common questions
Is this lamp the same bulb used in the D865W module listing?
Yes, 5811118543-SVV is the same bulb in both listings. This one omits the housing, so it suits owners whose existing cage and reflector are still in good condition.
Will this bare bulb fit a Vivitek D86GAB?
This particular listing is recorded only against the D865W and DW866. The D86GAB is listed under the module version of 5811118543-SVV instead, so check which one matches your projector before ordering.
How long should I let the projector cool before changing the bulb?
Allow the projector to cool completely after switching off and unplugging it, since the glass and surrounding metalwork stay hot for some time after the lamp goes out. Only open the compartment once it is cool to the touch.
What does 5811118543-SVV refer to on the packaging?
It is the part number we use to list this lamp, and the only reference code recorded for it. Match it against the number on your old bulb or the sticker inside the lamp bay to confirm it is correct for your projector.
Does the projector need a timer reset after I fit the new bulb?
Many Vivitek models keep a running total of lamp hours and will continue showing a replacement warning until that counter is cleared, usually from a lamp or maintenance menu in the on-screen display.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
