BenQ W770ST 210W Replacement Lamp

This new 210W projector lamp module is designed for the BenQ W770ST model. It arrives as a fully assembled bulb and housing unit, allowing for straightforward installation without extra assembly steps. The unit uses a Philips UHP bulb rated for 4000 hours in normal mode and 6500 hours in economy mode. It suits users needing a direct OEM-specification replacement for a dimming or failed original lamp.

Build Quality and Daily Handling

The lamp module is manufactured to ISO 9001 standards and undergoes checks for beam performance, ignition, voltage, appearance, connections and run-time. Because the bulb comes pre-installed in its housing, handling during replacement is limited to the module itself, reducing the risk of contaminating the burner surface. The housing fits the projector's existing lamp compartment and connects via the original power interface, so no wiring modifications are required.

Compatibility Check Before Ordering

Verify that your projector is the BenQ W770ST and that the service manual references part number 5J.J7K05.001. Confirm the projector's lamp-hour counter can be reset after installation to track the new module's 4000 to 6500 hour rating accurately. Ensure the projector's cooling vents are clear so the 210W lamp operates within its thermal design limits. This lamp is not for users whose projector requires a different wattage, connector layout or physical housing dimensions.
