Fenix HP30R Rechargeable LED Headlamp employs power and versatility in rare form and design. The power comes in two wonderfully pleasing forms. The first being that is powered by two 18650 rechargeable batteries that allows for convenient extended runtimes in an easy to recharge case that has the unique ability to also charge your USB rechargeable devices. The other power component comes from the sheer brute strength of its powerful beam. The three unique LEDs can all be used at once to disperse an amazing 1750 Lumens that reaches over 650 feet (200 meters) showing you items in the distance that few would imagine.
