Questions about this item

Does the 230 W UHB lamp match the power specification of the original Hitachi CP-X440 module?

Yes, the DT00691-BTI is rated at 230 W UHB, matching the factory specification for the CP-X440, CP-X443, CP-X444, CP-X445 and CP-X455 projectors.

Will the lamp housing align with the mounting tabs on a Hitachi CP-X445?

The replacement lamp is built to the same form factor as the original module, so it seats directly into the CP-X445 lamp cage without adapters.

Power off and unplug the projector, allow it to cool, remove the lamp cover, swap the module, replace the cover, then use the menu to reset the lamp timer to zero.
