BenQ SP840 300W Replacement Lamp

The BenQ SP840 is a new 300W projector lamp module supplied with a Philips UHP bulb pre-fitted in its housing. It is designed for owners of compatible BenQ projectors who need a direct, ready-to-install replacement when the original lamp reaches end of life. The unit arrives fully assembled so no separate bulb handling is required.

Replaces Worn SP840 Modules

This lamp replaces an exhausted SP840 module rated for 2,000 hours of typical use. The upgrade is worth it when the projector image has dimmed noticeably, colour fidelity has drifted, or the on-screen timer warns that the rated hours have been exceeded. A fresh module restores rated brightness and colour balance without projector recalibration.

Sustained Output Over 2,000 Hours

Under continuous operation the 300W UHP bulb maintains stable ignition voltage and beam performance for the rated 2,000-hour lifespan. ISO 9001 production checks verify run-time consistency, ignition reliability and connection integrity so output does not decay prematurely during long presentations or classroom sessions.

Questions about this item

Which BenQ projectors accept the SP840 5J.J2N05.011 lamp module?

The SP840 lamp module is designed as a direct replacement for BenQ projectors that specify the 5J.J2N05.011 part number; check your projector's manual to confirm compatibility before purchase.

What is the correct procedure for installing the SP840 lamp, and which step do users often miss?

Power off the projector and let it cool completely, remove the lamp cover, loosen the retaining screws, slide out the old module, insert the new SP840 unit until it seats firmly, tighten the screws, replace the cover, then reset the lamp timer in the projector menu — skipping the timer reset is the most common oversight.

How long will the 300W UHP bulb in this module last before it needs replacement?

The lamp is rated for 2,000 hours of typical use; after that period brightness will decline and the projector will indicate that a new lamp module is required.
