Are you ready for a bright idea? Introducing the Petzl NAO Headlamp. This revolutionary little headlamp automatically adjusts to your needs. Pretty cool, hey? The built in sensor measures the ambient light in order to adjust the 2 high-output LEDs. Let’s say you’re reading a map at close range while trying to find that perfect early-dawn fishing hole, the beam adjusts to a wide beam. If you are trail running, the beam adjusts to where you are looking; veering down at the path, the beam widens, but once you raise your head, the beam intensifies and becomes more focused. This is one little impressive technical light that is hands-free ahead of the competition. Buy em here.
