Direct-fit 400W replacement

This 400W UHM lamp module replaces the Panasonic PT-EW640U projector lamp (ET-LAE300). It ships as a fully assembled bulb and housing for straightforward installation. The unit suits education, business and home-cinema users who need a reliable new light source without sourcing bare bulbs.

Rated 3000 to 4500 hours

Normal mode delivers approximately 3000 hours of operation, while economy mode extends life to around 4500 hours. The 400W UHM bulb maintains consistent brightness and colour balance throughout its rated span. ISO 9001 production checks cover ignition, voltage and run-time to keep thermal behaviour predictable.

Ready for Panasonic projectors

The assembled housing matches the original mechanical interface, so no extra tools or adapters are required. Swapping the module restores full image output and frees the projector from dimming or shutdown warnings. Buyers needing a different wattage or a bare bulb without housing should look elsewhere.

Questions about this item

How do I install the PT-EW640U lamp module and what step is often missed?

The module ships as a fully assembled bulb and housing. Power off and unplug the projector, let it cool completely, open the lamp cover, remove the old module, insert the new one until it seats firmly, replace the cover, then reset the lamp timer in the projector menu — skipping the timer reset is the step most people forget.

What maintenance or replacement will this lamp need later?

The UHM 400 W bulb is rated for 3,000 hours in Normal mode or 4,500 hours in Economy mode. When the projector indicates end of life or brightness drops noticeably, replace the entire lamp module again; no separate filter or bulb-only change is required.

What limit appears first during sustained use of this 400 W lamp?

The rated lamp life of 3,000 hours (Normal) or 4,500 hours (Economy) is the first hard limit; the bulb will reach end of life before any other component in the module wears out.
