The advantages of self-adjusting REACTIVE LIGHTING technology

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.

Lighting adapts automatically according to need (light output and beam pattern). The self-adjusting lighting mode increases the burn time of the headlamp, due to optimized use of the rechargeable battery. Average lighting associated with the headlamp is calculated from field tests.

* Example of lighting curve for self-adjusting lighting. It varies according to headlamp use.

Lighting is kept at a constant, generally high, intensity for the specific burn time associated with the headlamp and decreases significantly at the end of this period. This type of lighting is designed for trails, for example, where full power is important.
