Description
xMeet the BLACK DIAMOND Cosmo 350 Headlamp
The Cosmo 350 is a compact, lightweight headlamp designed to keep your hands free while you explore, camp, or commute after dark. It delivers up to 350 lumens with a bright, even beam that helps you see texture, trail edges, and the warm glow of a campfire without glare. The beam is tuned for balanced spread, reducing hot spots, so you can stay aware of your surroundings on longer outings. A simple, one-handed button interface makes quick brightness tweaks easy, even on the move. The headlamp sits close to your head for a low-profile feel that won’t pull or bounce on rugged terrain.
Power options for flexible field use
- 3x AAA batteries are included for immediate use right out of the box
- Compatibility with the rechargeable BD 1500 Li-ion battery provides extended run time on longer trips
Versatile lighting modes
- Dimming to fine-tune brightness for tasks or trail navigation
- Strobe for signaling or visibility in low-light environments
- Red night-vision mode to preserve your natural night adaptation while reading maps or gear
Rugged and weather-ready
The Cosmo 350 is IP67-rated, enabling confident use in rain, snow, and splashes. After exposure to wet conditions, a thorough dry-out helps maintain long-term reliability and performance.
Comfortable, secure fit
The low-profile design and adjustable strap sit comfortably for extended wear. Its balanced weight minimizes fatigue during long hikes, climbs, or runs, so you can focus on your route rather than the gear.
Real-world scenarios
- Setting up camp under starlight or inside a tent with minimal ambient light
- Nighttime trail runs with steady, controllable brightness
- Inspecting gear or navigating a map after dark without using both hands
Why choose Cosmo 350
Designed for dynamic outdoor moments, the Cosmo 350 blends reliable illumination, flexible power options, and a comfortable fit to support a range of activities. It offers possibilities for safer navigation and practical tasks in low-light environments, without promising outcomes you can’t control.
