Replacement lamp for PT-DW750U projectors

This module delivers a genuine Ushio NSH 310W bulb pre-fitted in its housing, matching the original ET-LAD70AW specification. It is intended for owners of the Panasonic PT-DW750U who need a direct, tool-free swap when the existing lamp reaches end of life. Buyers whose projectors use a different lamp code or wattage will not be served by this part.

Thermal and power profile in daily use

The lamp draws 310W during operation, so the projector’s cooling system handles the associated heat load exactly as designed for the factory unit. Acoustic output remains consistent with the original lamp because the bulb geometry and power level are unchanged. No additional power-supply headroom or external cooling is required beyond what the PT-DW750U already provides.

Behaviour under sustained load

In standard mode the rated life is 1500 hours; switching to economic mode extends this to 2000 hours by reducing drive current. The bulb maintains stable ignition and colour performance across those intervals because each unit is tested to ISO9001 criteria for run-time, voltage and beam quality. Users who run the projector continuously for very long sessions should plan replacements around the chosen mode’s hour rating.

Questions about this item

How do I install the ET-LAD70AW lamp module in the PT-DW750U projector?

The module arrives as a fully assembled bulb and housing. Power off and unplug the projector, let it cool, remove the old lamp door and module, insert the new one until it seats firmly, replace the door, then reset the lamp timer in the menu.

When will the Ushio NSH 310W bulb need replacement?

Rated life is 1500 hours in standard mode or 2000 hours in economic mode; replace the lamp module when brightness drops noticeably or the projector signals end of life.

What limits sustained brightness on this 310W lamp?

The 310W Ushio NSH bulb reaches its rated hours first; extended runs in standard mode hit 1500 hours sooner, while economic mode stretches it to 2000 hours before output declines.
