Suits owners needing a direct-fit OEM lamp

Buyers who want a cheaper compatible module or a different wattage bulb should look elsewhere. The lamp is built only for the CP-SX635 series and will not operate in other projector families. No alternative versions or upgrade options are included in this listing.

The 275W UHB bulb delivers up to 2000 hours in standard mode and 3000 hours when the projector runs in economy mode. This single figure decides whether the replacement cycle matches your usage schedule.

Questions about this item

How do I install the DT00873 lamp module in my CP-SX635 projector and which step is often missed?

Power off and unplug the projector, let it cool completely, remove the lamp cover, loosen the retaining screws, slide out the old module, insert the new DT00873 housing until it seats firmly, tighten the screws, replace the cover, then reset the lamp timer in the menu — the timer reset is the step most often forgotten.

What maintenance or replacement will the Ushio 275W bulb need later?

The Ushio 275W bulb is not user-serviceable; after 2000 hours in normal mode or 3000 hours in economy mode the entire DT00873 lamp module must be replaced with a new unit.

What limit appears first during sustained use of the 275W lamp?

The rated lamp life of 2000 hours in normal mode or 3000 hours in economy mode is the first limit reached; brightness will gradually decline until replacement is required.
