New C4 LED Technology pumps up the brightness up to 3x more light intensity.

Streamlight introduces a whole new kind of LED. With a brighter, more powerful, blinding light than any LED that’s come before. The new Streamlight-engineered reflector with C4 Photonic Crystal technology almost triples the brightness and creates an intense beam that pierces the darkness. So you get the long-run times and indestructibility of an LED with a new level of brightness that leaves other LEDs in the dark. 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". Because 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.
