The Petzl IKO CORE rechargeable headlamp combines multiple technologies to offer 500 lumens at only 79 g. Featuring an Airfit® headband, an ultra-thin lamp body and an energy source worn in the rear, the headlamp is balanced and comfortable enough to be imperceptible. The multiple LEDs are ideally distributed to provide uniform lighting, for optimal visual comfort. Thanks to its hybrid concept design, the IKO CORE comes with the CORE rechargeable battery and is also compatible with three AAA/LR03 batteries (not included). This headlamp is very versatile. It can be worn around the neck, placed on a table, attached to a tent pole or a tree to be transformed into a lantern, using the storage pouch. Reflective components on the rear make the user visible in low light conditions. It can be flattened to reduce bulk, making it practical for all your outdoor activities.
