Surefire e2d led defender ultra flashlight, 500 lumens - SureFire Defender Ultra Dual Output LED Flashlight

I generally have shot NRA High power Rifle and Handgun metallic silhouette competitions. Recently, I have taken a number of CCW classes; training included instructions for shooting in low light situations. The courses were taught by retired military, border patrol, and police officers. They generally all carried SureFire Flashlights. I was very impressed with function of the light between low and high intensity settings. One could easily move through a dark hallway or room with the low light setting and if encountering a belligerent move to the high lumen setting which will generally disorient the belligerent.
I chose the SureFire E2D Led Defender because of: its two light settings, its reliability, its compact, its easy to carry, it can be deployed with one hand, and complements CCW conditions.
