Direct-fit BenQ projector lamp

The BenQ 5J.JA705.001 is a 310W UHP replacement module that ships as a complete bulb-and-housing assembly for immediate installation. It is built for owners of compatible BenQ projectors who need a drop-in light source without rewiring or alignment steps.

Lamp life and operating modes

Normal mode delivers 2,500 hours of runtime, while Economy mode extends that to 3,500 hours by reducing output and power draw. The 310W rating sets the thermal and electrical load the projector must support, so the unit cannot be used in chassis designed for lower-wattage lamps.

Replaces a spent or dimming original module

Swapping in this assembly restores factory brightness and colour balance when the existing lamp reaches its rated hours or shows visible degradation. The jump is worthwhile when image quality has fallen below usable levels; it is not intended for projectors that require a different wattage or form factor.

Questions about this item

Which 5J.JA705.001 version should I choose — OEM, BenQ-sold OEM, alternative OEM or compatible?

The OEM versions use the original Philips 310W UHP bulb; the compatible version is built with genuine OEM parts to the same ISO 9001 quality checks for beam performance, ignition, voltage, appearance, connections and run-time.

What does the 310 watt rating mean once the lamp is in my projector?

It draws 310 W of power, producing the brightness the projector was designed for while lasting 2,500 hours in normal mode or 3,500 hours in economy mode.

Does the 5J.JA705.001 use a standard lamp interface that limits brightness or life?

The lamp uses the projector’s proprietary UHP socket and ballast, so the 310 W rating and 2,500 to 3,500 hour life are determined by the projector’s own power delivery, not by a universal standard.
