Illuminate your adventures with the PETZL DUO S, an ultra-powerful, waterproof, and rechargeable headlamp designed for caving, rescue, and demanding outdoor activities.

Experience astonishing light with up to 1100 lumens in BOOST mode, powered by a high-capacity, rechargeable Lithium-Ion battery that eliminates the need for disposable cells. The DUO S is engineered for durability and performance, featuring IP67 waterproofing (submersible to -1 meter for 30 minutes) and robust construction to withstand tough environments.

Choose from five versatile lighting modes—low-intensity flood for close-range, mixed- and focused-beam for movement and rapid movement, and a highly-focused beam for long-range vision—ensuring you always have the right light for the task at hand.

The innovative FACE2FACE anti-glare function automatically dims the light when another DUO headlamp is detected within 8 meters, making it safe and comfortable for team use and group work underground.

The headlamp’s ergonomic design includes a rear-mounted battery pack for optimal balance and easy-to-use controls, even with gloves. CONSTANT LIGHTING technology delivers stable, consistent output over time, and electronic locking prevents accidental activation during transit or storage.

Includes mounting plates for use with VERTEX and STRATO helmets, and an ACCU 2 DUO S charger for rapid recharging in just four hours. Perfect for cavers, rescue crews, arborists, and professionals who demand reliable, hands-free lighting in harsh conditions.
