Description & Tech Specs

Do you crave subterranean adventures? So does the DUO S caving headlamp! Ultra-powerful, with 1100 lumens in BOOST mode, the this lamp runs on a rechargeable battery. Waterproof and durable, it’s ready to take on the moisture and mud of underground caves. When you’re in a group, you can count on the comfort provided by the FACE2FACE anti-glare function, which allows you to face each other without blinding one another. What will you explore today?

  • Five lighting levels, plus BOOST, to adapt lighting to a variety of situations:
    - Close-range lighting: low-intensity wide 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
  • Highly durable:
    - Waterproof in up to 1 meter of fresh water for 30 minutes and up to 3 meters for 10 minutes when passing through sumps while caving
    - Excellent fall, impact, and crush resistance
  • Rechargeable battery:
    - 3200 mAh Lithium-Ion battery
    - Recharges in 4 hours with quick 110/240 V wall charger (included)
    - Energy gauge
    - Carry a spare battery for long expeditions, or simply to switch out the battery when it dies (R2 battery available as an accessory)
  • Increased safety and comfort when working in a group with the FACE2FACE anti-glare function, which automatically dims the light when two or more beams cross, enabling those using DUO headlamps to face each other without blinding one another
  • Reliable and ergonomic:
    - Rotary switch, operable even while wearing gloves
    - Automatic lock function prevents the lamp from turning on during transit or storage
    - Automatically switches to reserve lighting when the battery is almost drained
    - Balanced, with the remote battery pack fixed at the back of the head
