Designed for convenient storage and transport, the Streamlight Stylus Pro USB Penlight is a benchmark in compact illumination. This extremely versatile light is small enough to carry in a pocket, and the pocket clip is removable for maximum utility. The anodized aluminum casing is tough enough to handle accidental drops or frequent travel, and the glass lens is gasket sealed for durability. Operating on C4 LED technology, this compact light produces a vivid 70-lumen beam that will shine at the same brightness level over the course of the battery's life due to the internal output regulator. It can be turned on and off easily via the push-button tail switch and features momentary and constant-on modes of operation. Water-resistant to one meter and ultra-convenient, this penlight is a useful tactical accessory for any modern operator.
