Lightweight and powerful at just 79 grams, the 500-lumen, rechargeable Petzl IKO Core can be worn as a headlamp or around the neck, placed on a table lantern-style, or attached to tent poles or trees.


  • Ergonomic, comfortable and versatile, thanks to the patented AIRFIT headband
  • Innovative, streamlined design with semirigid headband and ultrathin lamp body
  • Rear-mounted battery pack distributes the weight of the headlamp over the entire head, making it balanced and comfortable enough to be almost imperceptible
  • Hydrophobic headband resists sweat and rain
  • Thin headband profile considerably reduces the area of contact and improves air circulation during dynamic activities
  • Quick and easy rear adjustment
  • Wear it on your head, around your neck or on your helmet
  • Quick adjustments turn it into a freestanding lantern, a wraparound spotlight on a branch or tent pole or a handheld diffuser bulb
  • Included storage pouch also serves as a diffuser to light a bigger area
  • Reflective components on the battery pack increase user visibility
  • Battery charge indicator and 2 separate locking functions help monitor and protect battery life
  • 7 LEDs provide homogeneous light distribution to optimize visual comfort
  • 2 beam types—flood or mixed—and multiple brightness levels meet different user requirements for proximity lighting, movement and distance vision
  • Operates easily with a single button
  • Hybrid Concept design allows the use of 2 different power sources without the need of an adapter
  • Comes standard with a Petzl Core rechargeable battery; also accepts 3 AAA batteries (AAA batteries not included)
  • Detects the power source and adjusts lighting performance (Core rechargeable battery = 500 max lumens, AAA batteries = 350 max lumens)
