Genuine Sony CS4 Replacement Lamp

The Sony CS4 projector lamp module LMPC121 supplies a new 120W UHP bulb inside a pre-assembled housing. It is designed for owners of compatible Sony projectors who need a direct replacement without separate bulb handling. The module delivers up to 2000 hours in normal mode or 3000 hours in economy mode.

Check Projector Compatibility First

Verify that your Sony projector accepts the LMPC121 module before ordering. Confirm the lamp compartment matches the CS4 form factor and that the projector's power supply is rated for a 120W UHP lamp. No special tools are required, but the projector must be cooled and unplugged before starting the swap.

Ready-to-Install Module for Quick Service

The lamp ships as a complete unit, so the old housing is removed and the new one slots in without aligning a bare bulb. This frees you from handling fragile quartz glass and reduces downtime during maintenance. The assembly is built to ISO 9001 quality checks for ignition, voltage and run-time consistency.

Questions about this item

Does the Sony CS4 LMPC121 lamp arrive as a complete module or do I need to buy a separate housing?

The lamp ships as a fully assembled 120W UHP bulb inside its housing, so no extra parts are required for installation.

How do I decide between the OEM, Sony-sold OEM, alternative OEM and compatible versions of the CS4 lamp?

All four versions meet ISO9001 quality checks for beam performance, ignition, voltage and run-time; choose the OEM version for the original bulb maker, the Sony version for the brand-matched unit, the alternative OEM for a different original manufacturer, or the compatible version for a lower-cost option built with genuine OEM parts.

What does the 2,000 to 3,000 hour rating mean for daily use in my projector?

In Normal mode the lamp lasts about 2,000 hours; switching to Economy mode extends it to roughly 3,000 hours, so at four hours a day you can expect roughly 1.4 to 2 years before replacement.
