Importance of authentic
Avoid using a generic projector lamp in your NEC M300XC projector. Be sure to always install an authentic NEC NP15LP lamp. Generics have been created using toxic materials including Krypton-85 and they are prone to explosions with a shorter lamp life. Installing them often damages the sensitive electronics in your NEC M300XC projector. NOTE: New air filters are shipped with the lamp and it’s recommended you replace them at the same time.
