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.


  • 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.
  • Maximum light output: 575 lumens
  • Lithium-Ion rechargeable battery:
    - performs well at low temperatures

    - can be replaced, if necessary, with two AAA/LR03 batteries (reduced performance)
  • CONSTANT LIGHTING mode is also available, guaranteeing stable lighting that does not diminish during the entire chosen burn time

    - MAX POWER, brightness prioritized
    - MAX AUTONOMY: burn time prioritized
  • Lock function to avoid accidentally turning it on during transit or storage
  • Headlamp is stable on the head: adjustable headband with top strap for technical activities
