The Petzl Actik CORE is a compact and versatile headlamp that is equipped with a high-output rechargeable battery. Offering a brilliant maximum brightness of 450 Lumens, it is ready-made for backcountry hiking, mountaineering, or trail running. The easy-to-use electronic push-button allows you to choose between multiple beams. In addition to the white LED there is also a red LED mode that allows users to maintain night vision even after the light is turned off.  It is attached to an adjustable, reflective headband that offers maximum support and nighttime safety. The headlamp is powered by the included Core Rechargeable Battery but can also be used with standard AAA batteries (sold separately), making it more versatile than many rechargeable headlamps.
