Surefire L6 LumaMax Flashlight

The SureFire L6 LumaMax Light is CNC machined from aerospace-grade aluminum and coated in a military specification Type III hard-anodized finish so tough that its knurled handle can saw through the aluminum of lesser flashlights. Powered by three lithium batteries (10-year shelf life), the L6 produces a peak output of 65 lumens (more powerful than typical four D-cell alkaline flashlight) and over four hours of total useful light. The L6 is equipped with a click-on/click-off tailcap pushbutton switch that gives the user the option of momentary activation (for emergency signaling) or the convenience of a constant-on click switch in a single switch.

The L6 LumaMax 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).
