Ready-to-install replacement lamp

The Hitachi HCP-78XW module supplies a new 190 W Philips UHB bulb inside a complete housing that matches the original DT00821 part. It is built for owners of compatible Hitachi projectors who need a direct swap without extra assembly steps.

Thermal behaviour in normal use

The 190 W lamp runs at its rated power for the specified 2 000 hour life cycle with no additional cooling requirements beyond the projector's own design. Standard operating noise and heat output remain consistent with the factory lamp.

Integration with your projector

The pre-assembled unit drops into the lamp compartment and locks in place, freeing you from handling a bare bulb or aligning separate components. No extra cables, adapters or firmware updates are needed to restore full brightness.

Questions about this item

How do I install the HCP-78XW lamp module and which step causes the most issues?

The module arrives as a fully assembled bulb and housing; power off and cool the projector, remove the old lamp cage, insert the new unit until it seats firmly, then secure the retaining screws before resetting the lamp timer.

What maintenance or replacement will the DT00821 lamp need after the rated period?

The UHB bulb is rated for 2,000 hours; once brightness drops or the projector warns of end-of-life, replace the complete lamp module — no separate filter or bulb-only change is required.

What limit appears first during extended use of this 190W lamp?

The 2,000-hour rated lamp life is the primary limit; after that runtime the bulb's output degrades and ignition reliability falls, signalling replacement.
