Petzl's Nao Reactive Headlamp adjusts the light output automatically depending on what you need, a low narrowly focused light for reading a map or a brighter wider light for looking at the trail ahead. You can also reprogram the way it operates to suit your activity.
Petzl says: Compact, powerful and rechargeable headlamp with REACTIVE LIGHTING technology for technical, dynamic activities. 575 lumens max.
With REACTIVE LIGHTING technology, the brightness of the NAO headlamp adapts instantly and automatically to the environment. The headlamp thus provides maximal brightness (7 to 575 lumens), a longer burn time, along with greater usability and fewer manual interventions. The rechargeable Lithium-Ion battery is suitable for frequent use.
