BenQ 5J.Y1B05.001 replacement lamp

This new 280W projector lamp module arrives as a fully assembled bulb and housing unit. It is designed for BenQ projector owners who need a direct replacement when their original lamp reaches the end of its rated life. The module fits the specific projector models that use the 5J.Y1B05.001 part number.

Installation and common issues

The pre-assembled housing means no separate bulb handling is required; the module slides into the projector’s lamp compartment and secures with the existing screws. Most installation problems occur when the lamp door interlock switch is not fully engaged or when the lamp-hour counter is not reset through the projector menu after fitting the new module.

Rated lamp life

In Normal mode the lamp is rated for 3,000 hours of operation. Switching to Economy mode extends the rated life to 4,000 hours while reducing brightness output. Buyers who need longer intervals between replacements should plan for Economy mode use where acceptable.

Questions about this item

How can I verify the lamp is working correctly after installation?

The projector should ignite without flicker, reach full brightness quickly, and the on-screen timer will begin counting toward 3000 hours in Normal mode or 4000 hours in Economy mode.

What comes in the box and is anything else required for installation?

The module includes a new P-VIP 280W bulb pre-assembled in its housing, so no separate bulb, tools or additional parts are needed.

Which version of the 5J.Y1B05.001 should I choose for my projector?

Four versions are stocked: the original OEM bulb manufacturer's lamp, the BenQ-sold OEM lamp, an alternative OEM lamp from a different bulb maker, and a lower-cost compatible lamp built with genuine OEM parts — all made to ISO 9001 standards.
