Genuine Sony VPL-CX4 replacement lamp

This 120W UHP module fits the Sony VPL-CX4 projector and ships as a complete housing with the bulb pre-installed. It is intended for owners who need a direct replacement without separate assembly. The lamp uses the manufacturer part number LMPC121 for identification.

Lamp life varies by operating mode

In normal mode the rated life is 2,000 hours, while economy mode extends the rating to 3,000 hours. Actual runtime depends on usage patterns, ventilation and how often the projector is power-cycled. The lamp will gradually lose brightness as it approaches these limits.

120W UHP bulb determines compatibility

The projector requires a 120-watt ultra-high-pressure lamp, so a module with a different wattage will not operate correctly. Buyers who need a higher-lumen or lower-power alternative cannot use this part. Only the specified 120W rating matches the VPL-CX4 power supply and optical system.
