Streamlight's ultra-light ProTac 1AAA compact personal flashlight is fully programmable and customizable. Although its small size may appear deceiving, C4 LED technology produces a 70-lumen beam of light that can be seen at 47 meters. There are three programs, for three distinct beam output levels, each of which consumes a lower amount of battery power. The push-button tail switch makes one-handed operation simple and the removable pocket clip and adjustable lanyard ensure easy carry. Durable, anodized aluminum comprises the frame and the light is IPX7 waterproof to 1 meter for 30 minutes. At just under 4" in length, it can easily fit into your pocket or vest, and comes with a tear-resistant nylon holster.
