Ready-to-install replacement lamp

The Panasonic PT-LW373 is a new 230W projector lamp module that arrives with a Ushio UHM bulb already fitted in its housing, so it slots straight into compatible Panasonic projectors without extra assembly. It is built for owners who need a direct swap when the original lamp reaches end of life.

Restores original brightness and runtime

This module replaces a worn or failed factory lamp and returns the projector to its specified 5000 hours in normal mode or 10000 hours in economy mode. The jump is worth it when image dimming, colour shift or a lamp-warning message appears, and a quick, tool-free change gets the system back to full output.

Suits users who want a drop-in OEM-spec part

It fits buyers who prefer a pre-assembled cartridge from a recognised bulb maker and do not want to handle bare bulbs or separate housings. It is not for technicians who only need the bare burner, for teams that service multiple projector models with a universal kit, or for anyone whose projector requires a different wattage or connector.

Questions about this item

Does the PT-LW373 lamp module include the housing so it fits straight into the projector?

Yes, the module is a fully assembled 230W Ushio UHM bulb inside its housing, matching the original ET-LAL500 form factor for direct replacement.

What is the correct reset step after installing the new lamp so the hour counter starts at zero?

After fitting the lamp, open the projector menu and run the Lamp Reset function; skipping this leaves the old counter active and can trigger premature warnings.

When should I plan to replace the lamp again based on the rated hours?

The Ushio UHM bulb is rated for 5,000 hours in Normal mode or 10,000 hours in Economy mode; schedule a replacement as the counter approaches the figure that matches your typical usage setting.
