IKO Core Headlamp

The Petzl IKO Core Headlamp is hyperlight and extremely packable so you can take it on alpine treks, rock or ice climbs, trail runs, or easy-going camping trips. Its AirFit headband is semi-rigid and packs small, and the rear, rechargeable Core battery boasts up to 100 hours burn time. Despite its ultralight, minimalist-minded design, the LEDs pack a blindingly 500 lumen power, and it can adjust via one singe button for easy use. There are locking functions so the headlamp doesn't turn on in your pack. Petzl included a clever storage pouch that transforms the headlamp into a lantern for the alpine bivvy.

I've been using my new IKO Core for a few weeks now and it's my new favorite headlamp. You hardly notice you are wearing it because it doesn't have an elastic headband and it stays super secure and stable while running. The light quality is super clear with no shadows or blind spots. Easy to adjust and recharges quickly between uses. I like the lockout feature for when I am storing it in the diffuser bag which also works as a lantern when you're camping.

Truly revolutionary the way the air-fit headband fits on your head. I have a tiny head and was impressed with the range of adjustability. I've seen it on a huge head and on my tiny head and it fits comfortably on both occasions. I love the recharge-ability and can carry an extra Core battery for longer missions! I already have many core batteries from other Petzl headlamps, so I don't even need to buy a new one! I love the lantern feature with the diffuser bag and it works well hanging around my neck at camp or hiking. Reinventing the wheel! Nice work Petzl!!


Is there a waterproof or resistance rating on this?


Would this fit on a climbing or biking helmet?
