Compatible Mitsubishi EX321 Lamp

This replacement lamp is designed for the Mitsubishi EX321 projector and ships with a genuine OEM bulb inside a compatible housing. It restores factory brightness and image quality for home theatre owners and classroom technicians who need a reliable light source. The unit arrives new and ready to install without additional parts.

Upgrade from dim or failed lamp

The lamp replaces an ageing or failed original module when brightness has dropped or the projector warns of end-of-life. Swapping it restores the manufacturer-specified output so presentations and films look as intended. The jump is worth it when the current lamp no longer meets the projector's performance requirements.

Simple housing swap

Installation consists of removing the old lamp housing and inserting the new unit, a process the projector manufacturer designed for user servicing. The compatible housing aligns with the existing mounting points and connector. The most common issue is forgetting to reset the lamp-hour counter after fitting, which leaves the replacement warning active.

Questions about this item

Does the EX321 lamp housing match the projector's original mounting points?

The housing is built to the same mechanical specifications as the original lamp so it seats in the projector's existing mount without adapters.

What is the correct orientation when inserting the EX321 lamp module?

Align the connector side with the projector's socket and slide the module straight in until the retaining screw holes line up; forcing it at an angle can bend the connector pins.

How long is the EX321 replacement lamp covered against defects?

The lamp carries a 180-day warranty that protects against defective materials or workmanship.
