The SureFire MN32 High Output 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 MN32 is a high-output replacement option for the smaller reflector of the 10X flashlight. When used by itself, it puts out a 110 lumen beam with a 90 minute run-time. When the MN32 is used simultaneously with the MN31, the resulting beam is greater than 500 lumens, with a run-time of less than 20 minutes.
