Virtually indestructible light-emitting diode (LED) light source produces a smooth, pre-focused beam with almost twice the light of a big 2-D cell flashlight. Small size, high output, extended runtime, and 10-year battery shelf life also make it perfect for camping, travel, disaster preparedness kits, and an excellent everyday-carry light.

The LED light source has no filament to burn out or break and lasts for thousands of hours. It has a rugged aerospace-grade aluminum body, Mil-Spec Type III hard anodized in olive drab. It is O-ring sealed and weatherproofed with a Total Internal Reflection (TIR) lens and pocket clip. There is a tailcap switch: Press for momentary-on, press further to click constant-on and a switch lockout that prevents accidental activation during transport or storage. The Max Output is 25 lumens and runtime is 4 hours. The Length is 4.00 inches and it weighs 2.60 ounces. It takes one 123A Lithium battery.
