The Surefire L2 is a compact, dual-output LED flashlight, with a high beam bright enough for tactical applications and a low beam for close work or extended runtime. Constructed of aerospace-grade aluminum with a rugged Military Specification hard-anodized finish, and powered by two lithium batteries (10-year shelf life), the L2 LumaMax features a white, five-watt LED. The L2's digitally controlled two-stage tailcap switch allows the user to choose either a low-output beam for close-up work or a high-output beam for full power applications press the tailcap switch slightly for the low beam, continue pressing to activate the high beam. Twist the tailcap for constant light on either beam setting.
The L2 produces useable light for approximately 18 hours on the low-beam setting; high-beam runtime is approximately 60 minutes. SureFire provides realistic output and runtime specifications based on scientifically obtained measurements.
