Lights
Microprocessor regulation and six
levels of output available on demand to meet any task.
High-output or long runtime: now you can have both in one rugged
LED flashlight.
Constructed of aerospace grade
aluminum with a rugged military specification hard-anodized
finish, and powered by two lithium batteries (10-year shelf
life), the U2 Ultra features a five-watt LED (Light Emitting
Diode) and the extended runtime typical of LED flashlights. The
U2 features a body-mounted selector ring that allows the user to
choose one of six output levels: from a battery saving two
lumens of light—perfect for finding your keys in the dark—to a
retina-searing 80 lumens at its highest setting. The U2 is
equipped with a click-on/off tailcap pushbutton switch that
gives the user the option of momentary activation (for
self-defense use or emergency signaling) or the convenience of a
constant-on “click” switch. The U2 also features microprocessor
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 U2 produces over 40 hours
of useful light on the lowest setting. 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. |
