Show Description

Could there be anything better than a headlamp that adjusts light output to the situation? We don't think so. Its integrated sensor analyzes and responds to reflected light. So when you start reading a map, the beam becomes soft and diffused. When you're moving, it uses a wide, mid-bright setting to show immediate obstacles. When you glance ahead, it brightens and narrows to let you pick out details.

  • Constant lighting mode can be customized with Petzl® software to create 4 personal profiles to suit activity.
  • Bigger rechargeable lithium ion battery (now 2600mAh) adds brightness. (Also uses 2 AAA batteries, with reduced performance.)
  • Level 1 output in reactive mode: 1 to 575 lumens, range of 10 to 135m. In constant mode: 430 lumen max, range of 130m, burn time of 1 hour 30 minutes.
  • Level 2 output: 7 to 290 lumens, range of 10 to 80m. In constant mode: 120 lumen max, range of 60m, burn time of 8 hours.
  • Includes 30cm USB cable for recharging from USB port on laptops, solar panels or battery banks.
  • Multifunction on/off switch can be locked to avoid accidental activation during storage or transport.
  • Helmet strap included.

Beam pattern

Beam pattern affects how much you can see within the area of light thrown from the headlamp. Wide beams are good for close-up; spot or focussed beams are good for long range visibility.
