AlexAndChristine > The main body tube.  The back is threaded for the tailcap.

AlexAndChristine > The emitter assembly.  This fits tightly into the front of the headlight when it is assembled and was locked in place with thermal grease (all of that white gunk).
AlexAndChristine > Another view of the completed headlight.
AlexAndChristine > The assembled headlight.  It is 1 1/8" in diameter and about 2.5" long.  One CREE XR-E LED.
