Don’t let a little dark get in the way of your next PB or adventure-race finish. With a night-defying boost mode of 1100 lumens and 3 different beam patterns, the Duo S is designed to help you go fast in the dark. Using Petzl’s patented FACE2FACE intelligent beam technology, the Duo S automatically adjusts its beam when it’s around other beams, reducing the chances of leaving your fellow adventurers seeing stars. The rear-mounted battery pack has a display so you always know how long you’ve got, and when it’s time to recharge. IP67 dust and water protection means the Duo S stands up to pretty much any weather you’re willing to suffer through.
FACE2FACE intelligent beam technology automatically reduces your light’s output when the beam crosses another beam.
Boost mode fires up all LEDs at once, for 1100 lumens of dark-defying light.
Customized beam patterns give you the right type of light for any activity, from close-up detail work (flood), to moving fast (mix of flood and spot), to scanning the distance (spot).
Rear-mounted battery pack balances out weight, making the light more comfortable when you’re on the move.
Easily rechargeable battery pack has a 4-level power display.
IP67 dust and water protection means it handles rainstorms and puddles like a pro.
Large control knob is easy to use with gloves on.
Lockout mode prevents accidental activation, reducing the chances of reaching for dead headlamp.
