The Petzl Duo S headlamp is an ultra-powerful, rechargeable headband flashlight that delivers up to 1100 lumens in BOOST mode. Designed for demanding outdoor and sport activities, it combines waterproof and impact-resistant construction with a removable 3200 mAh Lithium‑Ion battery and the FACE2FACE anti‑glare function that reduces glare when users face one another.

Advantages

The DUO S offers five lighting modes plus a temporary BOOST mode to adapt illumination to different tasks, from wide, low‑intensity lighting for long burn time to a focused beam for distance vision. It is waterproof to 1 meter for 30 minutes (IP67 equivalent), resistant to impacts and crushing, and features a removable, rechargeable 3200 mAh battery with an energy gauge and quick 4‑hour charge using the included 110/240 V charger. Ergonomic features include a large glove‑friendly button, automatic lock to prevent accidental activation, reserve mode when battery is low, and a balanced design with the battery pack positioned at the back of the head.
