Ready-to-install lamp module

The Panasonic PT-VW431EA lamp is a complete 280W replacement module that ships with a new Ushio NSHA bulb already seated in its housing. It is designed for technicians and AV teams who need a direct swap without handling bare bulbs or aligning reflectors. The unit fits the ET-LAV200 slot and restores factory brightness in minutes.

OEM-grade housing and ISO 9001 checks

Each module is assembled from genuine OEM parts sourced from Ushio and other approved manufacturers, then tested for beam performance, ignition voltage, connections and run-time. The pre-aligned housing eliminates focus drift after installation and protects the bulb during transport and handling. Build quality meets ISO 9001 process standards across every production batch.

2 500 to 4 000 hour rated life

Normal mode delivers 2 500 hours of operation while economy mode extends the rating to 4 000 hours, giving operators a clear trade-off between brightness and replacement interval. The lamp ships as a single ready-to-fit unit with no extra cables, filters or software required. Buyers who need a bare bulb for custom housings or a different wattage for another projector model should look elsewhere.

Questions about this item

Which projector models accept the 280 W ET-LAV200 lamp module?

The ET-LAV200 is designed as a direct replacement for the Panasonic PT-VW431EA projector, matching the original 280 W specification and housing dimensions.

What physical space and mounting points does the assembled lamp housing require?

The module arrives as a complete bulb-and-housing assembly built to the projector's original form factor, so it slides into the existing lamp compartment and secures with the same mounting screws.

What is the correct installation sequence for the ET-LAV200, and which step is most often missed?

Power off and unplug the projector, allow it to cool, remove the lamp cover, release the retaining screws, pull out the old module, insert the new one until it seats firmly, re-tighten the screws, replace the cover, then reset the lamp-hour counter in the on-screen menu — the counter reset is the step most frequently overlooked.
