Bryant Lear

Best headlamp I have ever owned

John Haskett

The battery life is no where close to what is listed on the web site, which is sad as I use fenix lights in my job and the have ton of life.

David Real

Its great, Battery life is a tiny bit short. However I use it for work and I have it on quite a bit.

Jason Brandt

Light weight and comfortable with and without a hat. The battery life is excellent, I only need to charge it once every 2-3 weeks. Provides more than enough light for dark streets and trails.
