Designed to accompany all your nighttime activities, the Cosmo 350 delivers a maximum output of 350 lumens, enough to effectively light up a trail, a campsite, or a bike ride home in the rain. Its new, more compact design reduces bulk while improving balance on the head, for lasting comfort even during extended use. The faceted reflector optimizes light diffusion, offering both excellent range and efficient battery life management.

An intuitive interface designed for action

Black Diamond has redesigned the ergonomics of the Cosmo 350 to make it quick and easy to use, even with gloves on. Its dual switch allows you to easily select different lighting modes without having to cycle through the entire range. The red night vision mode, which can be activated directly, preserves your adaptation to darkness, while the dimmer and flashing mode offer great freedom of use depending on the context.
