Acer X1373WH Projector Lamp 210W Osram UHP 4000-6500 Hrs

Acer X1373WH 210W Replacement Lamp

This is a new 210W replacement projector lamp module built for Acer projectors that use the X1373WH part number. It arrives as a fully assembled bulb and housing, so the unit is ready for immediate installation. The lamp uses an Osram UHP bulb rated for 4,000 hours in normal mode and up to 6,500 hours in economy mode. It suits users who need a direct, like-for-like replacement without sourcing a bare bulb.

Installation and Common Issues

The module fits into the projector’s lamp compartment without tools, and the housing aligns with the original mounting points for a secure seat. Most problems arise when the lamp door is not fully closed, preventing the safety interlock from engaging, or when the usage timer is not reset after fitting the new module. Dust on the lens or air filters can also reduce brightness and shorten the effective lamp life.

Capacity and Headroom

At 210W the lamp delivers the brightness and colour performance specified for the original projector model. In normal mode it provides up to 4,000 hours of operation, while economy mode extends this to 6,500 hours by lowering output. Once the rated hours are reached the bulb will dim noticeably and may fail to ignite, signalling that a replacement is required.
