SureFire L4 "LumaMax" Led Flashlight

Constructed of aerospace grade aluminum with a rugged military specification hard-anodized finish, and powered by two lithium batteries (10-year shelf life), the L4 LumaMax features a five-watt LED (Light Emitting Diode) and the extended runtime typical of LED flashlights. With a maximum light output of 65 lumens, the L4 is the first LED flashlight bright enough to qualify for tactical use. The L4 is equipped with a new click-on/click-off tailcap pushbutton switch that gives the user the tactical advantage of momentary activation or the convenience of a constant-on “click” switch in a single switch. The L4 also features digital current regulation circuitry to match the LED's current requirements with the battery's output to maintain a more consistent level of light output for the useable life of the batteries (as opposed to unregulated lights, which are subject to a steady decline in light intensity beginning shortly after activation). The L4 produces 65 lumens of light for over an h
