Compatible replacement lamp housing

The Advanced Lamps TH685i-LAMP-A module is a brand-new lamp-and-housing assembly engineered for the BenQ TH685i projector. It arrives as a complete unit so installation is straightforward and no separate bulb handling is required. The genuine AL Series lamp inside is built to match the projector's optical specifications.

Home-cinema owners needing a direct swap

This part suits anyone whose TH685i has dimmed or reached its rated lamp hours and who wants a drop-in replacement without modification. Buyers who need a bare bulb without the housing, or who own a different BenQ model, should look at other listings because this module is specific to the TH685i.

90-day warranty coverage

The manufacturer backs the lamp assembly with a 90-day warranty period from purchase. This limited coverage is the key specification to weigh when deciding if the protection window meets your expected usage cycle.

Questions about this item

How often will the TH685i-LAMP-A lamp need replacing under typical daily use?

The lamp module is rated for standard projector cycles; actual replacement timing depends on your brightness mode and total hours logged on the BenQ TH685i.

What component reaches its limit first during marathon gaming or movie sessions?

The lamp's brightness output degrades gradually; the 90-day warranty period covers early failure, not gradual dimming from extended daily runs.

Does the housing fan or lamp run louder or hotter when the projector stays on all day?

The replacement module matches the original lamp design, so heat and acoustic levels stay consistent with the factory BenQ TH685i specifications.
