• RELIABLE PERFORMANCE: With Petzl's 50:50 Brightness-to-Burn-Time ratio, your Petzl headlamp will retain 50% of its original brightness halfway through the Burn-Time, rather than the 20-30% brightness you get in other brands.
• HYBRID CONCEPT: Petzl headlamps can run on either the CORE rechargeable battery or three AAA batteries without an adapter.
• FULL TILT: Petzl headlamps can be tilted up or down — allowing users to illuminate their surroundings while wearing the headlamp on their head or neck.
• EASE OF USE: Battery indicator shows the battery level each time lamp is turned on or off. Glow-in-the-dark reflector for locating the lamp in the dark. Rechargeable via micro USB port when using with CORE battery.
• LOCK FUNCTION: Prevents headlamp from accidentally turning on and draining the battery when not in use.
