The P7 remains one of our most iconic flashlights to this day, and we have decided to update its design. The P7 Core, successor to the P7, still features one of our most innovative lighting technologies, the patented³ Advanced Focus System, which allows a smooth transition from a wide beam of light to a sharply focused long-distance beam. Additionally, the P7 Core includes Rapid Focus technology for one-handed use and continues to operate on four AAA alkaline batteries.
