Beyond Power & Intelligence

Using an integrated light sensor technology, the headlamp beam instantly adapts to the changing conditions around you, giving you ideal lighting at all times with little manual intervention.
Called Reactive Lighting, the new Petzl headlamp technology features an integrated light sensor that can automatically asses your proximity to an object, your current level of activity, and your desire to see in the distance, adjusting both the beam pattern and light output accordingly.
The light sensor sits at the top of the Nao headlamp, facing the same direction as the beam. The sensor first measures and analyzes the amount of reflected light, then instantly and automatically adjust the beam to either a wide, focused, or dual pattern output, as well as adjusting the level of light intensity.
Two high powered LEDs work together to give you a minimum of 7 lumens to a maximum of 355 lumens of light.
When you are trying to tie a knot, cook dinner, or read a map, the Nao headlamp will project a wide beam with a lower power level appropriate to the distance of the object in front of you. When you are hiking along a trail, the beam will again be wide but with a medium strength light level. When looking off into the distance, the beam will become focused and more intense to help you locate objects far away.
With minimal manual intervention, Reactive Lighting technology increases the burn time of the Nao headlamp by over 3 hours, optimizing the use of the Li-Ion rechargeable battery. An integrated USB connector enables you to use your computer or any standard USB charger to refuel. An optional belt kit lets you move the battery pack from your head to your hip, useful for winter or high activity adventures.

Lighting performance for the NAO headlamp 
The OS by Petzl software allows the user to maximize the NAO's potential. Thanks to customized performance, the headlamp's lighting power, burn time and distance can be adjusted. The user may choose from a range of pre-configured activity profiles (trail running, mountaineering, etc.)
For more versatility, personal profiles may also be created according to the user's specific needs. Once the profiles are loaded into the NAO, they are easily accessed at any time.
Allows the rechargeable battery to be moved to the belt to reduce the weight worn on the head, or to keep it warm in winter.

Recharges easily with the integrated USB connection

When looking at an object at close range, for example when reading a map, tying a knot or setting up a tent, the beam is very wide and less powerful.
Lighting adjusts automatically to the distance of the object
When walking, running, etc., the beam is wide and has medium strength in order to illuminate obstacles in the path
When raising the head to see into the distance, looking for a trail marker or an anchor on a climb, for example, the light output increases and becomes more focused.
