Duo S

The Petzl® DUO® S is a rechargeable headlamp delivering up to 1100 lumens in BOOST mode, built for professionals who need dependable lighting in wet, dirty, or high-impact conditions.

Sold in Petzl's professional Operators line, it is used by rope access technicians, mine and tunnel crews, rescue teams, and anyone working through the night at height or underground. Its FACE2FACE® anti-glare technology automatically dims the beam whenever two or more DUO beams cross, so crews working face to face are not blinded by each other's light. Waterproof to IP67 and built to resist falls, impacts, and crushing, it suits teams who cannot risk a light failing mid-task.
