Petzl Duo S Waterproof and Rechargeable 1100 Lumen Headlamp

The DUO S is Petzl's most powerful professional headlamp: 1100 lumens from a multi-beam head unit with a rear-mounted battery that balances the load across your head. It is built for people who work in the dark for a living and for cavers who need serious output for hours at a time.

Its defining feature is FACE2FACE. When two DUO beams cross, both automatically dim so team members can look at each other without blinding one another, then return to full power. CONSTANT LIGHTING holds the output steady rather than letting it fade as the battery drains.
