Petzl Actik® Headlamp – 450 Lumens for Active Nights. Trail running at dusk, trekking until twilight, or summiting with a headlamp – the Actik® is designed for those who don’t want to check the time outdoors. With 450 lumens, it provides powerful, even light to guide your way, even on steep terrain. The integrated red light protects the night vision of those around you – perfect for group activities or reading maps at night. And if you happen to set it down: the phosphorescent reflector helps you find the lamp again in the dark. The Actik is powered by three AAA batteries (included), but it is also compatible with the rechargeable Core battery – thanks to the Hybrid Concept. For those who frequently use their lamp, we recommend the Actik Core model.
