Direct replacement for NEC and Infocus projectors

This GreenTechLLC NP22LP lamp replaces the original NP22LP, SP-LAMP-082 and 3797772800-SVK modules used in NEC PH1000U, PX700W, PX750U, PX800X series and Infocus IN5552L, IN5554L, IN5555L projectors. It fits the same housing without modification and arrives new in compatible housing and bulb assembly.

Economy mode extends usable life to 3000 hours

Rated at 400 watts, the lamp delivers 1500 hours in normal mode and up to 3000 hours when the projector runs in economy mode. Sustained output remains stable across the rated span, reducing the frequency of replacements during heavy daily use in classrooms or boardrooms.

Compact 4-inch cube housing weighs 0.75 lb

The lamp measures four inches on each side and weighs three-quarters of a pound, matching the original form factor for tool-free installation. Buyers needing higher-wattage modules or proprietary OEM-branded lamps with longer warranties should look elsewhere.
