Coast G10 LED Flashlight TT7831CP is a tiny, potent utility flashlight that goes anywhere and lights up anything. At less than one inch in diameter, the G10 is one of the smallest flashlights out there, but it still manages to pack 18 lumens of bright, focused light into its small frame. Coast has outfitted the G10 Flashlight with their Max Beam Optic System to create a tight "inspection beam" pattern that has no dark spots. The lightweight aluminum casing of the Coast G10 Flashlight is hardy enough for daily, rigorous use but light enough that it won't weight down your pocket. You can carry the G10 anywhere; it is both impact and water resistant, plus it's backed by Coast's lifetime guarantee. This Coast flashlight can operate for up to 2 hours and 15 minutes on a single AAA battery. A compact, bright flashlight with an unbreakable LED bulb at its center, the Coast G10 Pen Light is an excellent utility flashlight for any situation.
