4Sevens Quark X AA-2 Flashlight QXAA-2 improves on the already-successful Quark flashlight formula with rugged construction, bright output, and an easy to use interface. Four-Sevens has constructed this compact flashlight to last, fashioning the body out of aircraft grade T-6061 aluminum, waterproofing the whole package to IPX-8 specifications, and crafting the glass lens with an exterior coat of sapphire and an interior non-reflective coating for optimum efficiency. This 4 Sevens flashlight can operate in eight different modes--Moonlight, Low, Medium, High, Max, Strobe, Beacon, and SOS--allowing you to conserve battery life if you're running low, signal for help, or disorient quarry with just a few turns of the bezel. Stand it on its tail for the flashlight's room-illuminating candle mode. You can switch between Max and Moonlight settings simply by tightening or loosening the bezel, or you can cycle through other modes by lightly depressing the power button. The Four Sevens Quark X AA-2 LED Flashlight improves on the original Quark series by adding CREE XM-L LED emitters for a focused, bright beam that doesn't quit. A reversible and removable clip makes this flashlight easy to carry, and it can last for up to 15 days of continuous operation in Moonlight mode. For a dependable, durable, bright, and long-lasting compact flashlight, purchase the 4-Sevens Quark X AA-2 Compact Flashlight.
