Jump to: Our Verdict / Features / Specifications

The Cosmo 350 is a versatile compact all-rounder that is perfect for the hills and your needs round the home. The Duel fuel means that while supplied with AAA batteries it is also compatible with Black Diamonds Lithium Ion BD 1500 battery. 

Black Diamond says: 

For multi-use camping, around the house, and outdoor adventures that require a simple light with both an all-purpose beam. As well as night vision. This user has the need to run the lamp on alkaline batteries if caught away from a power source for a long backpacking trip.

Our Verdict

The Black Dimond Cosmo 350-R is a compact all-rounder that is handy to have whatever the situation, either out in the wilderness or for your needs around the house.

With an integrated 1500 mAh Li-Ion battery that cranks out a 350-lumen max output, a micro charge port meaning that it can be recharged  at home or on the go with a power bank, a lock mode to prevent accidental waste of light, integrated % battery meter to show when you are running low and red night vision mode when the situation calls for a gentler light.

While not completely waterproof it will withstand heavy rain and even being submerged for a short time, as long as the battery is dried out afterwards, meaning that you don’t have to worry about it failing you on a wet day in the hills.
