There''''s'' a star out there that''''s'' known to be the brightest in the universe. 0-4, they call it. So when we set out to name these super-bright keychain lights, the decision was made for us. Small but intensely luminous, our stylish task lights are in an orbit of their own. These little guys weigh a mere .03 ounces. But you wouldn'''t know it by the light they generate. A strong L.E.D. bulb shines from inside an aluminum housing on the 0-4 High Beam. The High Beam is also water-resistant and impact-resistant. Features an on/off push button and a comfortable rubber grip. Attach one of these fine lights to your keychain, your backpack, your jacket or anywhere there''''s'' a call for instant, brilliant light.
