BenQ MX823ST DLP Replacement Lamp with Genuine OEM Bulb

Direct MX823ST replacement

This lamp assembly is built specifically for the BenQ MX823ST projector and ships with a genuine OEM bulb inside a compatible housing. It restores the original brightness and colour performance the projector was designed to deliver. Installers and AV technicians can swap it in without adapting brackets or wiring. The 180 day warranty covers defects in materials and workmanship.

Practical limits of a lamp module

Light output declines gradually with use and the projector will eventually signal that a new lamp is required. The module does not alter native resolution, contrast ratio or any processing feature of the MX823ST. Operating the projector in high altitude or dusty environments can shorten the useful life of the bulb. The housing is not user serviceable beyond complete replacement.

Check your current setup

Confirm the projector model number on the rating plate matches MX823ST exactly before ordering. Verify that the existing lamp compartment is free of broken glass or melted plastic that could damage the new assembly. Ensure you can access the lamp door and have the required screwdriver for the retaining screws. Do not install if the projector shows signs of overheating or power supply failure.
