Magnets are the main attraction of these rugged flashlights
NightStar magnetic flashlights produce more than 20 mins. of bright light with just a 30-sec. shake. Require no batteries. Magnetic charger uses zinc-plated ceramic magnets bonded in either end of a polycarbonate housing. The high-strength magnet is the only moving part. When flashlight is shaken, charging magnet rebounds between repulsion magnets, generating electrical energy as it passes repeatedly through wire coil. Energy in coil is then stored in corrosion-resistant, high-energy capacitor. Recharge several hundred thousand times. When charged, capacitor powers LED. Acrylic lens and reflector project light from LED into concentrated, uniform beam that measures 12 ft. in dia. at a distance of 50 ft. Flashlights resist extreme temperatures, shock, and vibration. Available in 3 colors: bright white, super-bright green, or red. Feature non-sparking, watertight switch. Ideal for emergency response, military, and marine applications.
