With REACTIVE LIGHTING technology, the brightness of the NAO head torch adapts instantly and automatically to the environment. The head torch 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.

Weight:  6.596oz/187g

  • REACTIVE LIGHTING mode: brightness adapts instantly to need, due to the light sensor. The lamp offers adapted, comfortable lighting. It helps keep the hands as free as possible and optimizes management of the energy source.
