Direct Replacement Lamp Module

This 300W projector lamp arrives as a fully assembled bulb and housing unit designed for BenQ MX764 projectors. The module uses a Philips UHP bulb and matches the original manufacturer part number 5J.J4N05.001 for straightforward installation without additional tools or alignment steps.

Rated Life Varies by Operating Mode

In normal brightness mode the lamp is rated for 2000 hours of use while economy mode extends the rating to 3000 hours. Actual runtime depends on projector settings, ambient temperature and power-cycle frequency so plan replacement intervals around the mode you use most often.

Replaces Aged or Failed Original Lamps

The unit restores full brightness when an existing lamp dims reaches its hour limit or fails to ignite. It is not suited for projectors that require a different wattage or housing design and buyers needing higher lumen output or a different form factor should verify compatibility before ordering.

Questions about this item

Which BenQ MX764 lamp version should I choose among the OEM and compatible options?

The OEM version from the original bulb manufacturer matches the factory part exactly, the BenQ-sold OEM is the same module under the BenQ label, a second OEM version uses a different bulb maker, and the compatible version uses genuine OEM parts at a lower cost.

What does the 300W rating mean for brightness and heat in my projector?

The 300W Philips UHP bulb delivers the light output the MX764 was designed for; expect the same lumen level as the original lamp and similar heat, so the projector’s existing cooling handles it without modification.

How does the UHP lamp interface connect and what limits its usable life?

The module plugs directly into the projector’s lamp socket and power connector; rated life is 2000 hours in normal mode or 3000 hours in economy mode, after which brightness drops and replacement is recommended.
