Extended runtime
high-intensity LED flashlight for tactical, duty, and general
use. Virtually indestructible power-regulated light-emitting
diode (LED) provides smooth, brilliant, pre-focused
tactical-level beam almost seven times the light of a big two
D-cell flashlight — bright enough to temporarily blind and
disorient a person by impairing out his night-adapted vision.
Sold as a complete system that includes one B90
battery, a mountable SmartCharger
charging cradle, AC transformer, and DC auto adaptor.
SmartCharger protects charging batteries from voltage spikes.
Long runtime, high light output, rechargeable battery make it
perfect for nightly duty use.
LED light source has no filament to burn out or break,
lasts for thousands of hours
Rugged aerospace-grade aluminum body, Mil-Spec Type III
hard anodized in black or olive drab
O-ring sealed, weatherproof
Tempered Pyrex® window
Tailcap switch — press for momentary-on, twist for
constant-on
Switch lockout prevents accidental activation during
transport or storage
The L4 produces 65 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 65 lumens for one hour,
then lower output for over 1.5 hours. Total runtime 2.5+ hours.
Construction - CNC machined aerospace-grade aluminum. Hard
anodized finish for extreme corrosion and wear-resistance.
O-ring sealed, Pyrex® lens, removable steel pocket clip
Patented lock-out tailcap feature allows the light to be
locked in the off position to prevent unintentional activation
during storage or transportation
Weatherproof and lightweight
No Hassle Lifetime Guarantee: If it breaks, we fix it!
