Compatible Replacement Lamp

The GreenTechLLC SP-LAMP-077 is a new 220-watt projector lamp designed to replace the original module in specific Infocus and BenQ models. It serves owners of the IN3924, IN3926 or MP780ST who need a direct substitute for part numbers SP-LAMP-077 or 5J.J0605.001.

Installation And Housing

The unit ships as a complete compatible housing and bulb assembly, allowing a straightforward swap without reusing the old cage. It fits the listed projectors mechanically and electrically, freeing the user from sourcing a bare bulb and handling a separate installation.

Rated Life And Limits

In normal mode the lamp is rated for 1,500 hours, while economy mode extends the rating to 3,000 hours. It does not support higher-wattage requirements or projectors outside the named Infocus and BenQ series, so buyers needing a different form factor or longer rated life must look elsewhere.
