Genuine OEM bulb for BenQ MW820ST

This replacement lamp uses a genuine original OEM bulb built to the exact projector manufacturer specifications. It is intended for owners of the BenQ MW820ST projector who need to restore original brightness and longevity. The assembly includes a high-quality compatible housing that holds the OEM bulb securely.

Simple housing swap with care

Installation consists of removing the old lamp housing and inserting the new assembly until it seats firmly. The most common issue is forgetting to reset the projector's lamp timer after replacement, which can cause premature warnings or shutdowns. Handle the bulb by the housing only to avoid contaminating the glass surface.

Verify the exact projector model first

Confirm that your unit is the BenQ MW820ST before ordering, as lamp housings are model-specific and not interchangeable. Check that the projector powers on and the lamp door closes correctly, since a faulty door switch can prevent the new lamp from striking. Ensure the operating environment is clean and ventilated to protect the OEM bulb's rated life.
