Why We Like The Cosmo 350-R Headlamp
Stargazing is best done without a light, but we always need a bit of brightness to help us get to the tent. Black Diamond's Cosmo 350-R Headlamp comes in handy every camping trip every night, and it's even helpful for housework in all the nooks and crannies.

Great headlamp
I have 4 black diamond headlamps. I bike ride with one. It stays with my bike for my work commute. I have one on my search and rescue helmet. I use it for hiking into the field. I also use it for repelling over the side of cliffs on car wrecks. I have one in my truck for all purpose use. And i have a backup that my daughter is currently using on dog walks. Love the red light. And love how adjustable the brightness is. All my lights are still working great. Oldest one is close to 10 years old and going strong.

So much to like
So much to like: great 1500 mAh battery and good light output, but stupid micro-USB charging port. Please change to USB-C and improve the drop rating to 2 meters. And as long as I’m dreaming, please improve the weather rating.

Great headlamp
This is perfect for backpacking due to it's weight and how long the battery lasts, but Black Diamond needs to get with the times and put a USB-C charging port on it. Every other small electronic I have can recharge on that cable, and when I'm counting grams I end up bringing my NiteCore headlamp because it is similar without needing another power cord.

Perfect Headlamp!
After years of service my previous headlamp finally called it quits, it was a bruiser, but checking and changing batteries is not ideal. I am so happy to have a rechargeable headlamp and ready put this thing to good use!

Sleek and light
The headlamp is very easy to use and works great. It's very light as if you aren't wearing anything. I can see great when I run thanks to this headlamp.

Starlight, Starbright
Who needs stars when you have this headlamp! It is light, snug, and perfect for nearly every outing. I love the different color options as well. Would 10/10 recommend.

Cosmo 350-R
I gave them to my sons for Christmas presents. They both very excited and said this was just what they needed but we’re forgot to ask. Thanks

Awesome headlamp!!
Super light weight! Has a cool dimming feature when you hold down the button. Did a lot of research on different headlamps and went with this… glad I did. Would recommend to anyone looking for a headlamp.

Great mid-price option
So far the Cosmo has not left me in the dark. This headlamp lives up to the bar of excellence as past Black Diamond headlamps that we still own (oldest one over 15 years!) I love the battery free rechargeable option.
