Genuine Sony CX4 Replacement Lamp

The Sony CX4 LMPC121 is a 120W UHP projector lamp module supplied as a complete bulb-and-housing assembly. It is designed for owners of compatible Sony projectors who need a ready-to-install replacement when the original lamp reaches end of life.

Verify Projector Compatibility Before Ordering

Check your projector manual or service menu to confirm the LMPC121 part number matches the required lamp code. The module delivers 2,000 hours in normal mode and 3,000 hours in economy mode, so ensure your usage pattern aligns with these rated lifespans.

Pre-Assembled Housing Simplifies Installation

Because the bulb ships already seated in its cage, no separate handling of a bare lamp is required. This reduces the risk of contamination or misalignment during the swap and lets you restore projection quickly.

Questions about this item

Does the LMPC121 arrive as a complete module or must I buy the housing separately?

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

Which of the four available versions should I select for my CX4 projector?

Three are OEM variants — original bulb maker, Sony-sold, or alternate OEM — and one is a value compatible; all meet ISO9001 quality checks.

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

Expect roughly 2,000 hours in Normal mode or 3,000 hours in Economy mode before brightness drops to half.
