Portable - No more frustrating limitations of "corded" lamps. The handy TITAN Stinger measures only 7 3/8 inches long and weighs less than 9 ounces, so technicians can move freely during inspections even in tight areas. Optimal performance - Xenon-filled bulb enhanced by patented, state-of-the-art dichroic filter lens technology transmits much more power than conventional bulbs. As a result, all leaks glow more brightly. Rechargeable - The Stinger is powered by a single rechargeable NiCad battery that delivers one full hour of continuous inspection time or several hours of intermittent use. A wall-mountable charger is also provided. A charging cradle sleeve with AC charging cord comes with the flashlight. Adjustable-focus beam - Offers choice of an spot beam for narrow-area inspection and flood beam if wider coverage is desired. Instant-on - The Stinger reaches its full power utilizing an "instant-on" bulb and is ready for leak inspection immediately. This eliminates waiting for warm up and saves valuable time. A spare bulb is stored in the tail cap. Durable - Made of a super-tough, non-conductive engineering polymer that's impact- and dent-resistant.
