DE.5811100784-S is sold here as a bare bulb, rated at 230 watts with a 3,000-hour expected life, for the Promethean PRM25 and five Vivitek projectors: the D925TX, D927TW, D929TX, D935EX and D935VX. With no housing included, it is fitted inside the cage that is already installed in your projector.
The complete module version of this same lamp, with housing built in, is available separately for anyone whose existing cage is damaged. This bare bulb also answers to 5811100784-S, PRM25-LAMP and 5811100784-SU, so match any of these codes against your old unit. Because this lamp serves two different brands, confirm your exact model name before ordering.

Common questions
Is there a complete module version of this bare bulb?
Yes, a version with housing already fitted, listed under the same part number, is available separately for anyone whose existing cage is cracked or damaged.
Does this bare bulb fit the Vivitek D935EX?
Yes, the D935EX is on the compatibility list for DE.5811100784-S, alongside the D925TX, D927TW, D929TX, D935VX and the Promethean PRM25, so the same bulb covers both brands.
What is the rated life of this bulb at 230 watts?
It is rated for 3,000 hours of use, after which most owners notice a drop in brightness or colour accuracy that makes fitting a replacement worthwhile.
Is PRM25-LAMP an older code for this bulb?
We list PRM25-LAMP, 5811100784-S, 5811100784-SU and DE.5811100784-S as the same lamp under different codes rather than an old and new version, so any of them matches this listing.
How do I fit a bare bulb into the Promethean PRM25?
Let the projector cool fully, open the lamp access panel as described in its manual, then lift out the old bulb by its base and seat the replacement the same way.
