Published · Researched 2026-09-21
Identifier: Petzl IKO CORE headlamp (reference E104BA00). | Lineup note: Petzl's ultralight running-oriented headlamp with the AIRFIT headband and rear-mounted power source; HYBRID CONCEPT (CORE rechargeable battery included, also accepts 3× AAA).
All prices and spec claims dated 2026-09-20.
Lineup & lineage (2023–2026)
The IKO Core launched as Petzl's minimalist 500-lumen answer to the ultralight headlamp category (Nitecore NU25 et al.). It has remained in the lineup largely unchanged since 2021: 500 lm, 79 g, rear-mounted CORE battery, no red light. The distinguishing design element is the AIRFIT headband — a wide elastic band that doubles as the battery holder — and the lamp's ability to fold flat and convert to a lantern in its storage pouch.
Overview
A 79 g, 500-lumen headlamp designed specifically for night running and fast hiking. The battery pack sits at the back of the head, balancing the ultra-thin lamp body at the front. Seven LEDs provide uniform flood/mixed lighting. Notable deliberate omission: no red light.

Community verdict
Runners love the near-weightless feel and the balanced front/back design — Cripple Creek Backcountry calls it "the perfect ski touring headlamp" and the go-to for night running. The AIRFIT band is praised for stability and sweat resistance. The recurring complaint is the absence of red light and the micro-USB port in a USB-C world; some users also find the flood-heavy beam less useful for spotting distant trail markers.
Durability & warranty-claim reality
The thin lamp body and elastic band are durable in practice; the AIRFIT band's integrated battery pocket is the main wear point (elastic fatigue over seasons). Petzl's 5-year lamp warranty and available spares make long-term ownership easy. Micro-USB cable/port wear is the most reported functional issue.
Year-by-year history
- 2023: Established in the lineup; widely reviewed as the ultralight running pick.
- 2024: Unchanged; community discussion shifts to wishing for a USB-C refresh.
- 2025: Still current with micro-USB; no successor announced.
- 2026: Current as of 2026-09-20 (E104BA00); aging charging interface is the main criticism.
Closest existing catalog rivals
- specs/nitecore-nu25-ul.md — the direct ultralight rival; lighter with USB-C, but lower max output and smaller battery.
- specs/petzl-actik-core.md — Petzl's general-purpose hybrid; heavier but has red light and a more conventional form.
- specs/petzl-tikka.md — lighter-duty Petzl option; far less output.
Care
Hand-wash the AIRFIT band periodically; do not machine-dry; store the CORE battery at partial charge; keep the micro-USB port clean.
Buying traps
- No red light — a dealbreaker for night-vision preservation and group camp use.
- Micro-USB in 2026 means carrying a legacy cable.
- 500 lm is only achievable on the CORE pack (350 lm on AAA).
Additional community voices
- Night-running communities consistently rank it among the most comfortable headlamps ever worn — "imperceptible" is the recurring word.
- The lantern-via-pouch trick is genuinely useful in camp and a favorite detail in owner reviews.
Spec gap-fill
Petzl's official beam-distance figures per mode beyond the 100 m maximum were not consistently captured (UNVERIFIED — treat as not resolved).
