Black Diamond Cosmo 350-R Headlamp — GRAPHITE

Black Diamond Cosmo 350-R Headlamp

A clean, capable rechargeable headlamp built for camping, trail use, and everyday outdoor adventures where you want reliable light without unnecessary complexity. The Cosmo 350-R delivers 350 lumens, IP67 waterproofing, red night vision, and a digital lockout in a 75-gram package that charges via Micro USB and runs for up to 225 hours on low.

Why We Carry It
It's the headlamp we recommend for campers and casual outdoor users who want a solid rechargeable light with all the features they'll actually use without paying for performance they don't need.

Highlights

• 350 lumen max output with 64-meter beam distance — Enough light for trail navigation, camp tasks, and technical use in the dark without the excessive output of a dedicated alpine or search headlamp. Three white modes cover low, medium, and high for the full range of everyday use.
• IP67 waterproof rating — Tested to operate at least 1 meter underwater for 30 minutes. A serious waterproofing standard that handles rain, stream crossings, and accidental drops in water without failing.
• Red night vision with dimming and strobe — Activates directly without cycling through white modes first. Preserves night-adapted vision for stargazing, reading in a tent, and any situation where maintaining dark adaptation matters.
• Patented digital lockout — Prevents accidental activation in a pack or pocket so the battery is full when you actually need it on a long approach or an unexpected bivy.
• 1,500 mAh integrated Li-ion battery with Micro USB charging — Recharges from any USB source without carrying spare batteries. The integrated battery meter displays remaining power percentage so you're never caught off guard.
• 225-hour runtime on low — Exceptional low-mode endurance for camp use, emergency situations, and multi-day trips where conserving battery matters.
• Recycled elastic headband with Repreve fiber — Comfortable against the skin with a sustainable material choice that reduces the environmental footprint of a piece of gear used on every outing.
• 75-gram total weight — Light enough to forget it's on your head on long approaches and trail runs.
• 3-year Black Diamond warranty — Backed by BD's standard warranty on a headlamp built and tested by people who use them in the mountains.
