The NAO is Petzl's first headlamp to use Reactive Lighting
A built-in light sensor adjusts output and beam size automatically
The NAO can be powered by a lithium-ion battery or two AAA batteries for emergency use
In addition to two powerful LED lights, the new NAO headlamp from Petzl has a light sensor. The headlamp doesn't just shine light, it measures ambient light to provide the ideal amount of output. It also uses a few other smart design features to give you a high-performing, convenient headlamp.
