Genuine Sony CS3 LMPC121 Lamp Module

This is a new 120W replacement projector lamp supplied as a complete module with the UHP bulb already fitted inside its housing. It is designed for owners of compatible Sony projectors who need a direct swap when the original lamp reaches end of life. The unit arrives ready to install without any separate bulb handling.

Verify Projector Compatibility Before Ordering

Confirm that your specific Sony projector model accepts the LMPC121 part number before purchasing. Lamp modules are model-specific and an incorrect part will not fit or function. Check the projector's user manual or the label on the existing lamp housing to ensure an exact match with this CS3 designation.

Suits Users Needing a Direct OEM-Style Replacement

This module suits anyone who wants a straightforward, ready-to-fit lamp that restores original brightness and rated life of 2,000 hours in normal mode or 3,000 hours in economy mode. It is not for buyers who want a bare bulb to install into an existing cage, nor for those whose projector requires a different part number or wattage.

Questions about this item

What comes in the box with the Sony CS3 LMPC121 projector lamp and is anything else needed for installation?

The package contains a fully assembled 120W UHP bulb inside its housing, so no separate bulb or housing purchase is required for installation.

Which version of the Sony CS3 LMPC121 lamp should I choose among the OEM and compatible options?

Three OEM versions exist — the original bulb manufacturer's lamp, the Sony-sold OEM lamp, and an alternative OEM lamp — plus a lower-cost compatible version built with genuine OEM parts; all meet ISO9001 quality checks.

What does the 2,000 to 3,000 hour lamp-life rating mean for everyday projector use?

In normal mode the lamp is rated for 2,000 hours and in economy mode for 3,000 hours, so a typical four-hour daily session would last roughly one to two years before replacement.
