Purpose-built for Hitachi CP-S840B

This replacement lamp module is engineered specifically for the Hitachi CP-S840B projector. It arrives as a complete lamp-and-housing assembly so installation is straightforward. The unit is supplied new and carries a 90 day warranty. It suits schools, businesses and home users who need a direct-fit spare.

Capacity and headroom

The lamp restores the projector to its original brightness and colour performance for typical presentation and video use. It will operate reliably within the projector’s designed duty cycle. Light output will gradually decline as the lamp ages and eventual replacement will be required again. No higher-capacity alternative is offered for this model.

Practical limits of the interface

The module fits only the CP-S840B chassis; it cannot be used in other Hitachi or third-party projectors. The 90 day warranty covers premature failure but does not extend to labour or projector damage. Buyers who need a longer warranty period or an original-bulb variant should verify availability before ordering.

Questions about this item

Will this CP-S840B-LAMP-A lamp and housing work with my existing Hitachi CP-S840B projector without any modifications?

Yes, the Advanced Lamps module is engineered for guaranteed compatibility with the Hitachi CP-S840B projector and installs directly as a complete lamp and housing unit.

After installing the lamp, how can I confirm the projector recognises the new CP-S840B-LAMP-A module correctly?

Power on the Hitachi CP-S840B and check the lamp timer in the projector menu; it should show zero or near-zero hours, and the image should display full brightness without warning indicators.

Does the CP-S840B-LAMP-A package include the complete housing assembly, or must I purchase a separate cage for installation?

The product is supplied as a complete lamp and housing assembly, so no additional cage or separate housing purchase is required for installation.
