Direct-fit lamp for HT1085ST

This replacement lamp is built for the BenQ HT1085ST projector and ships with a genuine OEM bulb inside a compatible housing. It restores factory brightness and colour accuracy for home-cinema owners who need a like-for-like module. Installers and enthusiasts who want original-spec output without third-party compromises will find it matches the projector's requirements.

Consistent output over full duty cycle

The OEM bulb maintains stable luminance and colour temperature across the rated lamp life instead of fading quickly after an initial peak. Its electrode geometry and gas fill are tuned to the projector's power supply, so brightness decay follows the manufacturer's curve rather than dropping off early. Users running daily movie sessions or extended gaming periods see predictable performance until the lamp timer signals replacement.

180-day warranty coverage

A 180-day warranty protects against defective units, giving buyers a defined period to verify reliable operation. The guarantee covers the complete lamp assembly, not just the bulb, so housing fit or connector issues are included. Purchasers who need longer protection or on-site service must look elsewhere.

Questions about this item

How much heat and fan noise does the BenQ HT1085ST lamp add during all-day use?

The genuine OEM bulb inside this housing matches the projector's original thermal design, so heat output and fan behaviour stay the same as with the factory lamp.

Does the BenQ HT1085ST lamp ship as a complete housing or just the bare bulb?

It arrives as a full replacement module — genuine OEM bulb already seated in a compatible housing — so no extra parts or tools are needed for installation.

Will this lamp work in an older BenQ projector that is not the HT1085ST?

The lamp is built to the exact specifications of the HT1085ST only; using it in a different model is not supported and could cause fit or performance issues.
