The rechargeable NAO headlamp adapts its two high power LEDs instantly and automatically to the lighting needs for greater comfort, fewer manual interventions and longer battery life. NAO is the first Petzl headlamp with REACTIVE LIGHTING technology.

The integrated light sensor is oriented in the same direction as the eyes; it measures and analyzes reflected light in order to instantly and automatically adjust the headlamp's beam pattern (wide and/or focused) and light output to the user's needs.

REACTIVE LIGHTING technology is a revolution in hands-free lighting. A built-in light sensor adapts the headlamp's beam pattern and light output instantly and automatically to suit the user's needs. This means the user gets an ideal amount of light with minimal manual adjustment required. This self-adjusting lighting mode also results in longer burn times, due to more efficient use of the rechargeable battery.

Adapted lighting

The shape of the beam and the power of the headlamp instantly adapt to the need (lighting for close, medium or long-range vision), so the user always has the right amount of light.

A minimum of manual adjustments

The headlamp automatically adapts to changes in surrounding light conditions, allowing the user to remain focused on the activity at hand without worrying about adjusting the headlamp.

Longer burn times

REACTIVE LIGHTING technology increases burn time, due to more efficient use of the rechargeable battery. Lighting adapts to suit the need, reducing the use of wasteful, unnecessarily powerful lighting.
