The Browning's Stoke provides you with high light output or long-lasting continuous runtime in the same package. The aluminum housing makes it tough and lightweight and it helps to keep the light cool, while the adjustable bezel allows you to focus the beam to your needs. It can use either a high-performance USB rechargeable battery (USB charger is built into the light) or a standard single CR123A battery. The Dual Fuel is a design concept that allows lights to run off of rechargeable or standard single use batteries, increasing the capability of your lights and giving you the best of both worlds.
