At home, on the job, or as deep as 30 feet underwater, the black 2AAA Xenon Mini Pocket Light from Underwater Kinetics illuminates tasks with a bright xenon bulb. Twist the head clockwise to turn the light on and counterclockwise to turn it off. The light meets requirements for non-incendive safety classification. Powered by two AAA alkaline batteries and made of ABS plastic/polycarbonate, it weighs just 1.3 ounces and can be clipped to safety glasses, a hard hat, or a cap brim, and it comes with a split ring for carrying on a key chain.
