The tiny LED Lenser P3AFS is a little wonder of engineering.
It includes the most innovative light focus technology for improved range and performance yet it is conveniently small for easy storage in a pocket or on a key-ring.
In use its patented Advanced Focus System allows quick transition from circular low beam to more sharply-focused long distance light.
A simple push-button switch at one end and easy-slide Speed Focus at the other make it a joy to use.
