The Black Diamond Cosmo is a hands-free headlamp that shines up to 200 lumens, making it easy to see trails, campsites or work zones when light is scarce.
Weighing just 86 grams, the Cosmo won’t weigh you down on long treks, and its use of three AAA batteries means replacements are easy to find in the field. You can switch between a focused beam that reaches up to 65 meters and a softer 12-meter flood for close-in tasks, giving you the flexibility to light distant landmarks or handle camp chores without carrying extra lamps.
With an IPX8 waterproof rating, this headlamp is sealed against continuous immersion, so heavy rain or accidental drops into water won’t interrupt your light. The IPX8 classification means it remains watertight even when submerged beyond one meter, offering reliable performance in wet conditions.
