Replacement lamp for NEC NP-M311WJL

This lamp module is built for the NEC NP-M311WJL projector and ships with a genuine OEM bulb inside a compatible housing. It restores original brightness and colour accuracy when the factory lamp reaches end of life. Installation follows the projector's standard lamp-change procedure.

OEM bulb inside compatible housing

The critical specification is the inclusion of an original OEM bulb rather than a compatible copy. That bulb is engineered to meet the exact manufacturer specifications for the NP-M311WJL, ensuring correct light output and rated lifespan. A generic bulb would not guarantee the same performance.

Consistent output under continuous use

Because the lamp uses the OEM bulb, it maintains stable brightness and colour during extended presentations or classroom sessions. The housing is designed to dissipate heat effectively, supporting reliable operation over long duty cycles. The unit is covered by a 180-day warranty against defects.
