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 100 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 100 lumens of light for over an hour, followed by
lower output for over 1.5 hours. Unlike most 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 of a shorter duration.
Battery - Two lithium
123A 3.0 Volt with 10-year shelf life (included)
Output/Runtime - Maximum output of 100 lumens for one hour,
then lower output for over 1.5 hours. Total runtime 2.5+ hours.
