Ready-to-install replacement module

The Hitachi CP-EX251N lamp module arrives as a fully assembled 225W UHP bulb inside its housing. It is designed for direct installation in compatible Hitachi projectors without additional tools or alignment steps. This new unit suits technicians and AV teams who need a quick swap to restore brightness. Buyers who require a bare bulb without the cage should look elsewhere.

Compatibility and fit

The module matches the original DT01481 specification so it seats in the existing lamp compartment and connects to the projector’s power leads. No external ballast, adapter or firmware update is needed for the swap. The housing reclaims the same footprint as the factory unit, leaving surrounding components undisturbed. Installers who need a different connector layout or voltage range cannot use this part.

Sustained output stability

Under continuous operation the 225W UHP lamp delivers a rated life of 5000 hours in normal mode and 6000 hours in economy mode. Output decline follows the typical UHP curve rather than a sudden drop, allowing predictable maintenance intervals. The lamp is manufactured to ISO9001 quality checks covering ignition, voltage and run-time consistency. Users who demand a longer single-lamp lifespan beyond these rated hours will not meet that requirement with this model.
