Compatible Hitachi CP-S840W lamp module

This replacement lamp and housing assembly is built for the Hitachi CP-S840W projector. It arrives new and ready to install, restoring brightness without requiring a separate bare bulb swap. The unit suits education and business users who need a quick, reliable return to service.

Drop-in housing frees up installation time

The lamp ships inside its original housing, so no disassembly of the old cage is required. Simply remove the spent module, insert this one, and reset the projector timer. The design eliminates the handling of a fragile bare bulb and reduces downtime during class or meeting changes.

Steady output over the rated service period

Under continuous operation the lamp maintains consistent illumination for its intended lifespan rather than peaking early and fading fast. The 90 day warranty covers early failures, giving IT staff a predictable replacement window. Weight is .9900.
