Petzl DUO S Rechargeable Headlamp with FACE2FACE Anti-Glare


Ultra-powerful with 1100 lumens in BOOST mode, the DUO S headlamp runs on a rechargeable battery. It is multi-beam and has five lighting modes, making it adaptable to many different situations: close-range work, proximity, movement, rapid movement, and long-range vision. Featuring the FACE2FACE anti-glare function, the DUO S headlamp allows those working in a group to face each other without blinding one another, to work together more effectively. It can be worn on VERTEX and STRATO helmets, thanks to the included mounting plates.



  • Five modes, plus BOOST, to adapt lighting to a variety of work situations:
    – Close-range lighting: low-intensity flood beam maximizes burn time
    – Proximity lighting: mixed beam with brightness suited for comfortable proximity vision
    – Lighting for movement: mixed beam includes focused lighting that allows for greater ease of movement
    – Lighting for rapid movement: more powerful mixed beam allows users to anticipate the terrain
    – Distance vision: highly focused beam for long-range vision
    – BOOST mode provides temporary maximum power of 1100 lumens
  • CONSTANT LIGHTING technology: stable lighting over time, ideal for long work periods
