Professional Replacement Lamp for InFocus Projectors

The BTI SP-LAMP-081 is a new projector lamp built as a direct replacement for the original InFocus module. It suits owners of the IN5142, IN5144, IN5145 or SP1081HD models who need to restore brightness after the factory lamp reaches end of life.

Consistent Output Through Extended Use

A high-quality lampwick maintains stable light output during long presentations or classroom sessions. The design resists the rapid dimming and colour shift that cheaper alternatives show after only a few hundred hours of continuous operation.

Simple Module Swap With No Alignment Needed

The lamp ships as a complete housing that drops into the projector without tools or optical adjustment. The only common issue is forgetting to reset the hour counter in the projector menu, which leaves the replacement warning active.
