Provides three-plus hours of light on just one AA battery
Multiple settings give you control of battery usage
Quick one-handed focusing
The M5 Flashlight’s unique, optimal heat-sync technology drives its single LED harder to give you three-plus hours of run time on just one AA battery (included). Smart Light Technology™ offers three settings to help conserve battery life: basic illumination, defense and low. Near to far focusing options with the Advanced Focus System are possible because of a patented combination of a reflector and lens to create a light system that provides both a focused beam for long-distance needs and a spill beam for up-close reading. Rapid Focus™ technology allows you to go from reading to searching by simply moving a sliding bezel with your thumb. Puts out 18 lumens for up to four hours on low power; puts out 100 lumens for up to three hours on high power. Length: 4.09". Weight: 2.61 oz.
