Lamp life varies by operating mode

In Normal mode the lamp is rated for 2000 hours of use. Switching to Economy mode extends the rated life to 3000 hours. Actual runtime will depend on usage patterns and environmental conditions. The lamp uses UHP technology at 120W.

Built to ISO 9001 quality standards

Each lamp undergoes checks for beam performance, ignition, voltage, appearance, connections and run-time before it leaves the factory. The housing ensures precise alignment with the projector's optical path. Buyers who need a higher-wattage module or a different connector layout should verify their projector's requirements before ordering.

Questions about this item

Which version of the Sony VPL-CS4 lamp should I choose?

Four versions are offered: the original OEM bulb, the Sony-branded OEM lamp, an alternative OEM bulb, and a compatible module built with genuine OEM parts; all are manufactured to ISO9001 standards and tested for beam performance, ignition, voltage, connections and run-time.

What does the 120 watt rating mean for daily use?

The lamp draws 120 watts and is rated for 2,000 hours in normal mode or 3,000 hours in economy mode, so brightness and power consumption stay consistent with the projector’s original specification.

How does the UHP bulb interface with the projector?

The module arrives fully assembled with housing, matching the factory connector and ignition requirements so it installs directly without adapters or firmware changes.
