Compact & powerful, the Stinger LED rechargeable flashlight offers 3 microprocessor controlled variable lighting modes & in addition to an attention getting strobe mode. The combination of rechargeable batteries and lifetime super high flux C4 LED results in one of the lowest operating costs of any flashlight made. Streamlight® introduces a whole new kind of LED. With a brighter, more powerful, blinding light than any LED that's come before. Since the Stinger LED Flashlight is equipped with powerful C4 LEDs, they are the perfect solution for a wide range of professional tasks that require extreme brightness, while benefiting from exceptionally long run times. The enhanced LEDs are made possible by a new development in laser chip manufacturing called Controlled Collapse Chip Connection or "C4". Since no two LEDs are precisely alike, Streamlight has carefully selected only LED suppliers that incorporate world-class technology in order to consistently produce 'prime cut' power LEDs for our Stinger LED flashlight. This means that our customers can be assured that the Streamlight® Stinger LED® flashlight with C4 LEDs are consistently bright, with improved light output efficiency.
