Original DT00781 Lamp & Housing

This new Jaspertronics module supplies a complete lamp and housing assembly built to the DT00781 specification. It is intended for Hitachi projectors that require this exact part code.

Suits owners of listed Hitachi models

The unit fits projectors identified by the codes 456-8770, 78-6969-9903-2, CL20X, CP-RX70, CP-X1, CP-X4, DT00781-UHP, ED-X20 and PJ358. Buyers with different projector models or those needing a bare bulb without the housing should look elsewhere.

Simple swap-in installation

The housing arrives pre-assembled so the old module can be removed and the new one seated in its place. The most common issue is forgetting to reset the projector's lamp-hour counter after installation, which can leave the replacement warning active.

Questions about this item

Which Hitachi projector models does the DT00781 lamp housing fit?

The DT00781 lamp and housing module fits Hitachi models CL20X, CP-RX70, CP-X1, CP-X4, ED-X20 and PJ358 as well as part numbers 456-8770 and 78-6969-9903-2.

Will the original lamp inside this housing work with the same ballast used in my older Hitachi CP-X1?

Yes, the Jaspertronics OEM lamp uses authentic specifications so it operates with the existing ballast in compatible models such as the CP-X1.

How can I confirm the DT00781 lamp is performing correctly after installation?

After fitting the module, power on the projector and verify a stable, bright image with no warning indicators; the unit should run quietly and maintain consistent brightness.
