Black Diamond Cosmo 350 Headlamp
THE BLACK DIAMOND COSMO 350 HEADLAMP IS A SUPER COMPACT AND WATERTIGHT HEAD TORCH
Keeping it simple by providing the features you need and nothing extra the Cosmo 350 Headlamp has a max 350 lumen output, red night vision, and runs on batteries or the BD 1500 rechargeable Li-ion battery.
With 350 lumens of power housed in a super compact, watertight body, the Cosmo 350 is perfect for urban adventures and overnighters in the woods. The Cosmo's new compact body is more ergonomic with a lower profile for improved balance, and the updated user interface includes a second switch for easy lens selection. The new Cosmo 350 is also Dual-Fuel compatible, allowing you to power the light with either the rechargeable BD 1500 Li-ion battery or three standard AAA batteries. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life. And thanks to its watertight construction, the Cosmo keeps lighting the way whether you're forced to bike home in the rain, or you're hiking back to camp in an unexpected downpour.

WHAT WE THINK
We’ve been using the Black Diamond Cosmo 350-R Rechargeable Headlamp on our recent hikes, and honestly, we’re really impressed with how well it performs.
With 350 lumens, it’s bright enough to light the way but not overly intense for close-up tasks. The rechargeable battery is a game-changer—it saves us from worrying about spare batteries and is a much more eco-friendly option for longer trips. We also really appreciate how comfortable it is to wear for hours, with a secure fit that stays in place, even when we’re on the move.
The various settings, including the red light mode for preserving night vision, have been super useful. For us, it’s the perfect balance of brightness, comfort, and convenience. It’s become our go-to headlamp for everything from evening hikes to early morning starts. -
