Impressive Battery Life

i love the rechargeable battery life, and the red light feature is great for reading in the tent without the brain shock of bright, white light.

Great Light With One Flaw

I've had this light for years and have used it camping, hunting, for SAR operations, and around the house. I just bought a few more, one for a gift and another for me to have laying around. Good beam/brightness options, long battery, light weight. Only thing wrong with this light is that the charging port needs to be updated to USB-C. Update the charging port and this is a 5-star light.

Surprisingly Powerful

Purchased as a backup for my much larger Princetontec Apex headlamp. Very impressed with this little guy, surprisingly powerful for such a small package.

This Little Light O Mine

stands up so far. easy to use and adustable. Can't wait to test it's water resistance paddling in 2026

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.
