The Guard Dog Xcess tactical flashlight provides a truly customizable light output in a gleaming 1200 lumen tactical flashlight. On its brightest mode, the Xcess can be seen almost a mile away. Switch to a low, energy consumption mode at 125 lumens and utilize nearly 48 hours of battery life. Need a customized output? The Guard Dog Xcess incorporates a unique user control button located conveniently at a natural grip position which allows you to tailor your light power between ultra bright and low beam levels, as well as switch to an emergency strobe function. Reset back to the ultra bright position at any time by pressing the tail switch, which also doubles as a discharge button to prevent accidental activation and unnecessary battery drainage. Need just one light function without cycling through different modes? Depress the tail switch to go from off to ultra bright and back to off. The durable Guard Dog Xcess is o-ring sealed for waterproof and all weather resistant capabilities. Built with type III aluminum alloy, the flashlight can withstand the most brutal conditions, yet easily clip on with its included belt clip. A light built for professionals, by professionals yet designed for your everyday use, the Guard Dog Xcess will exceed your every expectation.
