The opinion of Aventure Nordique

Black Diamond's Cosmo 350-R is a 350 lumen headlamp that will suit lightweight enthusiasts looking for a durable and versatile light. It runs on a built-in rechargeable battery, which charges directly on the headlamp through the micro-USB charging port. It has a 3 LED battery meter on the right side so you can get a better forecast of your power consumption.

With an IP67 waterproof rating, it will perform well after aquatic submersion of less than 30 minutes to a maximum depth of 1 meter. It will not fail during your treks where the weather is capricious and will illuminate you, in full power, over 60 meters.

It has a dimmer switch and can assist you when you want to remain discreet at night thanks to the red LED night vision mode, which also has a dimmer switch and a flashing mode.

A facet reflector will allow you to optimize energy consumption.
