The SureFire MN30 Lamp Assembly is a specially engineered lamp that, when combined with its designated and carefully engineered reflector, will produce SureFire's brilliant and perfectly-focused beam. The reflector is either integral to the head of your flashlight, or part of the prefocused lamp assembly.
You can purchase either standard high-output replacement lamps for your flashlight, or optional ultra-high output lamps that nearly double the light output (available for most flashlight models). Ultra-high output lamps use more energy, and therefore deplete batteries more quickly.
The MN30 is one of two standard replacement lamp assemblies for the 10X flashlight. This is the lamp from the smaller reflector, and it produces a 60 lumen beam for 180 minutes.
