ViewSonic Pro8800WUL OEM Replacement Projector Lamp 370W

Ready-to-install 370 W lamp module

This replacement lamp module arrives fully assembled with a new 370 W Ushio bulb inside its housing. It is designed for the ViewSonic Pro8800WUL projector and matches the original RLC-103 part. The unit is supplied new and passes ISO 9001 quality checks for beam performance, ignition, voltage, appearance, connections and run-time. Installers can fit it directly without extra tools or alignment steps.

Installation is a direct swap

The module slides into the projector’s lamp compartment and locks in place, so no wiring or bulb handling is required. The only common issue is forgetting to reset the projector’s lamp-hour counter after fitting the new module, which can leave the replacement warning active. Dust on the housing vents can also reduce airflow, so a quick clean of the compartment before insertion helps maintain normal operating temperature.

Rated for 370 W projector power draw

The lamp is built to operate at the projector’s specified 370 W power level, and its ignition and voltage characteristics are verified against that load. Running the projector in eco or low-power modes is supported, but the lamp’s rated output and life figures are based on the full 370 W setting. It is not a universal module; it fits only the Pro8800WUL series and will not work in projectors that require a different wattage or housing design.
