The creation of the original Streamlight Stinger set the standard for duty lights. The Stinger DS LED reinvented this classic light with a modern twist. Tough, bright and portable, it boasts a variety of functions to ensure versatile reliability for whatever situation crosses your path. This durable American-made flashlight has three different settings plus a strobe function, all activated by dual-switch technology via the tail cap or head-mounted switch. C4 LED technology allows for a concentrated beam of light that, with the help of a deep-dish parabolic reflector, delivers maximum peripheral illumination for easily lighting a dark room, hangar or alley. With up to a 7.25-hour run time at the lowest setting, this flashlight will not let you down.
