This flashlight is one of the lightest and most compact quad LED 18650-powered flashlights ever designed! It has an awesome user interface with insane output. One of the few truly pocketable 18650 quad LED lights! You can make it even smaller with an optional 18350 tube or 18500 tube. A handy pocket clip is also available.
We have received several messages regarding what appears to be a "cracked" optic. The Carclo optic used in this light has a "gate crop" on one corner of the lens by design---this is not a crack. Please see this picture for a visual description. The Carclo 10622 lens has an irregularity in this corner of one of the reflectors right out of the sealed tray, directly from Carclo. It does not significantly affect the optical quality of the lens.
