Show Description

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.
  • Includes the ACCU 2 Lithium-Ion rechargeable battery (3200mAh) and 110/240 V charger.
