The LED LENSER® F1 is not for those with weak nerves. We call it the fighter jet amongst small-flashlights.

What this lighting powerhouse has concealed inside a minimally dimensioned package, is simply breath-taking: 400 Lumen from a single CR123 battery!  This world best is achieved by the LED LENSER® F1 as one of the first in its class.  But that is just the beginning : HA III anodising in accordance with military standards, watertight (IPX8), electronic regulation with a temperature sensor,  tail stand, replaceable glass breakage ring and usage optimized lighting are facts that will convince even the most demanding expert. You'd best get a LED LENSER® F1 fighter jet installed in the hangar at your home as soon as you can.
