The rechargeable IKO CORE headlamp combines multiple technologies to offer 500 lumens. Featuring a lightweight  headband, an ultra-thin lamp body and an energy source worn in the rear, the headlamp is balanced and comfortable. Thanks to its HYBRID CONCEPT design, IKO CORE comes with the CORE rechargeable battery ($30 value) and is also compatible with three AAA/LR03 batteries (not included). It is versatile: can also be worn around the neck, or transformed into a lantern, using the storage pouch. It can be flattened to reduce bulk, making it practical for all outdoor activities.
