The K3 Key-ring torch from Ledlenser is ideal for home, camping, automotive, and emergency use. This key-ring torch features its own integral light focusing, it has a bigger head for a wider range and features Blue Moon Focus System, which creates a blue edge around a central bright white light. The focus of the K3 torch can be adjusted from flood (for close-up viewing) to a spot beam that can reach up to 33 meters distance at 15 lumens, even with this small size key-ring torch, which measures less than 7cm and weighs only 34gr. The K3 key-ring torch is made with a very strong aluminum casing and is powered by 4 x AG13 batteries included.
