Surefire L1 Lumamax
Produced by Surefire
The
Surefire L1 is a Digitally-Controlled LED flashlight. It uses a cree
LED and digital current regulation circuitry to achieve a near
constant level of brightness for the useable life of the batteries.
The L1 also comes with a two-stage tailcap switch. Press lightly for
low (10 lumens) and press hard for full power (65 lumens). Twist for
constant on. The L1 can also be locked-out by unscrewing the tailcap
several turns.
The L1 runs
on 1 CR123 lithium batteries for an average of 90 minutes in
regulation and has an average brightness output of 65 lumens. After
~65 minutes, brightness will drop off sharply, giving you decreasing
brightness until the battery gives out. The L1 uses a Surefire
designed TIR optic to focus the light into a tight beam while still
providing useful side spill.
