Petzl Actik® Headlamp – 450 Lumens for Active Nights. Trail running at twilight, trekking until dusk, or summiting with a headlamp – the Actik® is perfect for anyone who doesn’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 – ideal for group activities or reading maps at night. And if you ever 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 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.
