Streamlight's ultra-light ProTac 1AA Professional Tactical flashlight is the perfect personal carry light. Its small size is convenient, but its patented C4 LED technology produces a piercing 70-lumen beam of light that can illuminate a dark alley or large room with ease. There are two distinct beam output levels, the lower of which can operate for 32 hours with low battery consumption. The push-button tail switch makes one-handed operation simple and the unbreakable pocket clip and nylon holster ensure easy carry. The durable polymer construction and impact-resistant tempered lens are lightweight enough for pocket storage and the casing is IPX7 waterproof to 1 meter for 30 minutes. At just over 4" in length, it is an ideal light for concealment and suits any profession or activity.
