The Streamlight JR F-Stop is an ultra-compact lightweight 2AA flashlight that features a power LED and Spot to Flood technology. With the bezel forward (for Spot mode) the light has a piercing beam. When the bezel is slid backwards, the beam opens up into a smooth flood pattern for area lighting. It is constructed of aluminum with a non-slip knurled grip, anodized finish, and polycarbonate lens. Included are two AA alkaline batteries and a rotatable pocket clip.
