So bright and lightweight
I like these black diamond headlamps so much. Something about the way they do the headband makes it very easy for me to adjust to my head. Lamp tilt down and can shine in my path. The dimming feature can get a nice dim, white light. Or the full bright is exceptionally bright. I use this when I'm backpacking. I like that the rechargeable option will work with my battery pack so that I don't have to carry spare AAA batteries anymore.

Lightweight and long battery life
Love BD headlamps, and love this one in particular for its light weight, functionality (red light a must!), rechargeable long battery life. My one ding on the BD headlamps is that the headbands tend to stretch out over time, so I have to replace them every few years.

Solid headlamp
The rechargeable feature was a no brainer. Much better than carrying extra batteries. 350 lumens is plenty bright. It's easy to change the brightness and switch to the red light.

Favorite headlamp yet!
Pros: bright enough for everyday tasks, red light is great, easy to adjust brightness, textures on/off button is easy to feel through gloves, light is compact. Cons: the blue battery indicator lights shine brighter than the red light its self when turning the headlamp off, an upgrade to USBC would be nice, micro USB feels outdated.

The head lamp that never needs batteries
Hey black diamond has always been my go to head lamp for dawn patrol ski missions or early morning runs. But now it’s rechargeable. Same solid light without the risk of the batteries needing to be changed

Have no idea if this is any good---infographic instructions make NO NO NO sense!!!
Just received this headlamp as a Christmas gift. Instructions make NO sense whatsoever. I have no idea how to turn this thing on, change the lighting mode, etc. Maybe someday I can change this rating, but as of now it is just a paperweight.
