The first thing to do is buy an OEM replacement lamp. Your NEC M260WS projector uses the NEC NP15LP projector lamp. Avoid the cheaper generic lamps with their shorter lamp life and toxic materials. They are prone to explosions and often damage the sensitive electronics in your NEC M260w projector.
NOTE: New air filters are shipped with the lamp and it’s recommended you replace them at the same time.
