What this lamp replaces

The Optoma DW318 is a complete 185 W projector lamp module that includes a new Philips UHP bulb already fitted into its housing. It is built for owners of compatible Optoma projectors who need a direct replacement without sourcing a bare bulb.

The spec that confirms fit

The critical figure is the 185 W power rating; the lamp must match the projector's original wattage to ignite correctly and maintain the rated 2000 hours in normal mode or 3000 hours in economy mode. Buyers whose projectors require a different wattage cannot use this module.

Installation and common issues

Because the bulb comes pre-assembled in the housing, installation is a straightforward swap of the old module. The most frequent problem is forgetting to reset the projector's lamp-hour counter after fitting the new unit, which leaves the replacement warning active.

Questions about this item

What brightness can I expect from the 185W bulb once it is installed in my projector?

The 185W UHP bulb delivers the rated light output for the DW318 module; actual screen brightness depends on your projector's optical engine and selected mode.

Does the lamp use a standard connector or a proprietary interface, and does that limit which projectors it fits?

The DW318 module is built to the Optoma SP.8EH01GC01 specification, so it connects only to projectors designed for that exact lamp assembly.

What physical space and mounting points does the complete housing require inside the projector?

The pre-assembled bulb and housing unit matches the original DW318 form factor, sliding into the lamp bay and securing with the projector's native latch.
