The Streamlight Stinger DS C4 LED Flashlight features an innovative dual-switch system that offers professionals across a variety of industries additional flexibility, especially in low-light situations. This flashlight gives you the power you need, to use one light for virtually any job to major operations such as lighting an accident, fire scene, or tactical deployments. The Streamlight Stinger DS LED Flash Light gives professionals such as the police, first responders, industrial workers and auto repair technicians the ability to choose between two fully independent switches, located at the tail-cap and at the light head. The Streamlight Stinger DS LED Light gives you full control over the flashlight's three microprocessor-controlled variable light levels and strobe function from each of the two fully independent switches located on the light head and tailcap. The shockproof, three-watt, super-high flux LED generates up to 80 Lumens of light, and Streamlight's proprietary deep-dish parabolic reflector focuses the LED's output into an powerful long-range beam combined with ample side illumination.
