SureFire E1L Outdoorsman, Compact Pocket Sized, Dual Output LED Flashlight, Max Output: 45 lumens.

Surefire ultra compact (finger length), dual-output mini LED flashlight with extended runtime. Its virtually indestructible, two-stage light-emitting diode (LED) light source produces a smooth, pre-focused beam that, at maximum output, is over twice as bright as that of a big two-D-cell flashlight.

At its low setting it produces a useful three lumens of light and continues producing useful light levels for 40 hours on a single lithium battery. Small size (it's lightweight enough to clip to hat brim for hands-free operation), dual output, extended runtime and 10-year battery shelf life make the E1L perfect for camping, backpacking, travel, emergency/disaster preparedness kits, or as an everyday-carry for general use.
