L1 LumaMax®
Constructed of aerospace grade aluminum with a rugged military specification hard-anodized finish, and powered by a single lithium battery (10-year shelf life), the upgraded L1 LumaMax features a 3-watt LED (Light Emitting Diode), a Total Internal Reflection (TIR) focusing lens, and the extended runtime typical of LED flashlights. The L1's digitally controlled two-stage switch allows the user to choose either a low-output beam for close-up work or a high-output beam for full power applications -- simply depress the tailcap switch halfway for the low beam, continue depressing to activate the high beam. Twist the tailcap to achieve constant light on either beam setting.

The L1 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 L1 produces useable light for up to 90 hours on the low-beam setting; high-beam runtime exceeds four hours. Unlike many LED flashlight manufacturers -- who inflate the light output and usable runtimes of their LEDs -- SureFire provides realistic output and runtime specifications based on scientifically obtained measurements. Although any LED -- including those produced by SureFire -- can continue to produce negligible light output for over 100 hours, the amount of "useful" light produced is typically of a shorter duration.
