Replacement lamp for Panasonic PT-EW540

This new projector lamp module fits the Panasonic PT-EW540 and uses the OEM part number ET-LAE300. It arrives as a fully assembled bulb and housing so installation is straightforward. The unit is built to ISO9001 standards and supplied by a specialist projector-lamp distributor.

Thermals noise and power draw

The lamp runs at 400 watts and uses a Ushio UHM bulb designed for stable ignition and consistent beam performance. Normal operating life is rated at 3,000 hours while economy mode extends that to 4,500 hours. Each lamp passes strict quality checks for voltage, run-time and thermal behaviour before it ships.

Lamp life rating decides suitability

Choose this module when the projector needs a 400 watt Ushio UHM lamp rated for 3,000 hours normal or 4,500 hours economy use. Buyers who need a different wattage, a longer-life bulb or a lamp for another projector model should look elsewhere.

Questions about this item

How do I install the PT-EW540 lamp module and what step do people often miss?

The module arrives fully assembled with the Ushio UHM 400W bulb inside its housing. Power off the projector, let it cool completely, then swap the old module for the new one — the step people skip is resetting the lamp-hour counter in the projector menu after installation.

What maintenance or replacement will this lamp need later?

The Ushio UHM 400W bulb is rated for 3,000 hours in Normal mode or 4,500 hours in Economy mode. When brightness drops or the replacement warning appears, replace the entire lamp module again; no separate filter or bulb-only change is required.

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

The 3,000-hour Normal-mode life (or 4,500 hours in Economy) is the primary limit — after that the bulb reaches end of rated output and the projector will prompt for replacement.
