The Petzl IKO® CORE headlamp is a lightweight, ergonomic, rechargeable headlamp providing 500 lumens of brightness and weighing just 79 grams.  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.

There are three white lighting levels: MAX BURN TIME, STANDARD (better power/burn time balance), and MAX POWER.  The headlamp can also be worn around the neck or transformed into a lantern using the storage pouch.

The headlamp comes with a CORE rechargeable battery and is also compatible with 3 AAA/LR03 batteries thanks to its HYBRID CONCEPT design (not included).  There is a burn time of between 2.5 hours and 100 hours depending on the lighting level used.
