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 (light emitting diode). 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 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). Compared to incandescent bulbs, LEDs provide
extended runtime and extreme resistance to malfunction due to
impact.
The L2 produces useable light for approximately 18 hours on the
low-beam setting; high-beam runtime is approximately 60 minutes.
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 insignificant light output for
over 50 hours, the amount of useful light produced is typically of a
shorter duration.
