Direct-fit Panasonic projector lamp

This 280W replacement module fits the Panasonic PT-VW431DEA and ships as a fully assembled bulb and housing. The unit uses a genuine Ushio NSHA lamp and is manufactured to ISO 9001 quality standards. It is ready for immediate installation without additional tools or alignment steps.

Replaces the original ET-LAV200 module

When the installed lamp reaches the end of its rated life or shows reduced brightness, this module restores factory light output. Normal mode delivers 2500 hours of operation and economy mode extends that to 4000 hours. The jump is worth it when image dimming or lamp-warning messages appear during regular use.

Practical limits of a 280W UHP lamp

Brightness and colour stability gradually decline as the lamp ages toward its hour rating. Economy mode lowers power draw and heat but also reduces peak luminance. The housing is sealed, so only the complete module can be swapped; individual bulb replacement is not supported.
