PETZL DUO S, 3200 mAh, 1100 lm, Headlamp

Designed for demanding activities such as caving, industrial work, and trail running, the PETZL DUO S Rechargeable Headlamp provides focused hands-free illumination. The main beam produces up to 1100 lumens, casting light up to 200 metres for long-range visibility. A lower 80-lumen setting covers closer ranges of around 20 metres for tasks at hand. On its lowest output, the headlamp offers a maximum runtime of 23 hours. It uses constant lighting technology to maintain consistent brightness as the battery discharges over time. An automatic shut-off feature helps prevent accidental battery drain during storage or transport.

Weighing 370 grams, this headlamp balances its weight with a rear-mounted battery pack connected to an adjustable, detachable headband. A large rotary switch operates the unit, even while wearing gloves. The housing has a shock-resistant build and offers a fixed beam angle without a pivoting head. Compatibility with PETZL VERTEX and ALVEO helmets makes it suitable for professional environments where head protection is required. A battery level indicator gives visible feedback on remaining power during use.
