SureFire 12PM
Produced by Surefire

The 12PM is a 4-123A cell flashlight designed for short bursts of 500 lumen light using the N62.

The 12PM can also use the M4 lamp assemblies:
225 lumens of light for 60 minutes with the MN60.
350 lumens of light for 20 minutes with the MN61.
500 lumens for 12 minutes total (not continuous) with the N62.
 

The reflector angle is different from the M4, giving the 12PM a tighter hot-spot.
 
 

You can place the 12PM's 2.5" Turbohead on a 9P and use the N2 lamp assembly.
You can also place the 9P bezel and lamp assembly on the M4 body,
providing you use a battery spacer to keep it at 9 volts.
 
 

Size comparison between the 12PM, 9P & M3.
The 12PM is longer than the M3 making it more difficult to carry comfortably.
