This flashlight is one of the lightest and most compact quad LED 26650-powered flashlights! It has an awesome user interface with insane output. The ramping feature allows you to dial in the exact power level you desire. This light is similar to the Emisar D4, but with higher capacity and slightly better thermal characteristics thanks to the bigger head and body.
This light comes with the magnetic tailcap. This light is not compatible with protected batteries, and is only guaranteed to work with the batteries listed below.
