Black Diamond Cosmo  

During the darkest days of the year, we took the opportunity to try the new Cosmo from Black Diamond.

Basics about the product
Cosmo has two modes, which are changed via a full click on the release button. The modes are one SuperBright LED and one-half watt LED.
Each one of these can be switched into 4 light settings, via a half click on the release button: 3 brightness settings and one strobe illumination. The pictures below shows the difference between SuperBright LED and one-half watt LED.

The weight is 80 grams, 2.8 ounces, with batteries.

Impressions
We have been using the lamp both when running and while chopping wood.

The adjustments made it easy to fit our heads and after some minutes of running we did not feel that we hade the lamp on our heads.

We preferred the one-half watt LED mode while running. It gave us a good view of the ground, even out in the forest . The lamp was easy to switch on and off. A feature that we used to save power when we where running our normal track with partly street lights.

The light from the one-half watt LED looked like a light tunnel when we where choping wood. Switching over to SuperBright LED gave more light in the surroundings and it was easier to work. A perfect mode when you have things around you that you are lightening up.

Summary
Cosmo is definitely a lamp that is worth bringing with you. The flexibility in the light modes made it very convenient to work and practice with.
 

One-half watt LED mode
This mode gives you a circle of light.
