Even when turned off, this handheld light emits a continuous soft glow with almost no drain on the battery, so you'll always be able to find it on a shelf or in purse, even in the darkest conditions. Because of its size, durability and long-lasting LEDs, it is perfect as an emergency or an all-purpose light--in fact, it is so versatile and dependable it has even accompanied the pilots of a twin-engine plane making a pole-to-pole circumnavigation of the globe. This light's efficient, patented LED technology helps its battery last 20 times longer than it would in a regular flashlight. When turned to its low setting, it can produce a 20-foot beam for 200 hours of continuous use; its high setting produces a 100-foot beam that lasts for 20 hours. The small LEDs emit pure white light that is as bright and powerful as conventional flashlights, plus they are sturdier and far less likely to break if dropped. A strobe light mode helps draw attention during emergencies, making this flashlight perfect for glove boxes or purses. The soft sanoprene case is moisture resistant for use in inclement weather. Requires one 9V battery (inlcluded). 1" H x 1 1/3" W x 3 1/4" L. (2.9 oz.)
