Direct replacement lamp

This 310W BenQ 5J.J8805.001 module arrives fully assembled with a new Philips UHP bulb inside its housing, so it fits straight into compatible BenQ projectors without extra steps. It is built for owners who need a genuine OEM-specification light source that restores original brightness and colour accuracy.

310-watt thermal load

The lamp draws 310 watts during operation, producing the heat and fan activity expected at this power level. Rated life reaches 2500 hours in normal mode and extends to 3500 hours when the projector runs in economy mode, reducing both power draw and acoustic output for longer sessions.

Upgrade from a dimmed module

Swapping out an ageing lamp that has fallen below usable brightness or started flickering brings the image back to spec. The change is worth it when the existing unit nears its rated hours or shows colour shift, but this module does not add features or resolution beyond the projector's native capability.

Questions about this item

How do I install the BenQ 5J.J8805.001 lamp module and what step is often missed?

Power off the projector, unplug it and let it cool completely, then remove the old module and insert the new 310W unit until it clicks; the step people skip is resetting the lamp-hour counter in the menu so the 2,500-hour normal or 3,500-hour economy rating tracks correctly.

What maintenance or replacement will this 310W UHP lamp need later?

The lamp itself is the only replaceable part; after roughly 2,500 hours in normal mode or 3,500 hours in economy mode the brightness drops and the module must be swapped for a new 5J.J8805.001 assembly.

What limit appears first during long sessions with this 310W lamp?

The 310W UHP bulb reaches its rated life limit first — about 2,500 hours at normal brightness or 3,500 hours in economy — after which light output falls below usable levels and the module must be replaced.
