Petzl Actik® Headlamp – 450 Lumens for Active Nights. Trail running at twilight, trekking until dusk, or summiting with a headlamp – the Actik® is designed for those who don’t check the clock outdoors. With 450 lumens, it provides powerful, even lighting 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 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.
