I've had the lamp since yesterday. It's ready to use, but it does need to be charged once. It's light, and because the clip is adjustable, it can be easily attached to different jackets and so on. It also comes with a head strap, so you don't necessarily need a baseball cape or something similar.
The light is sufficient for me. It's very good for me.

Great lamp, I can only recommend it. The luminosity is pretty good, as is the scattering pattern. The strap that comes with it means you can use the lamp as a headlamp without a baseball cap. The battery lasts longer than expected.

Perfekt

up until now I have always had a headlight on a band and got very frustrated when the band got so loose that it slipped down. As I wear a peaked cap every day to clean up my patio after the [ have finished eating, a clip on headlight is so useful and, in the case of Klarus, bright and effective. Thank you.

I have this clipped to my ballcap, resting on my nightstand. On nights where I need to get up in the middle of the night for a trip through the house to the restroom I just don the cap and hit the light switch on the unit and confidently walk around the house without the need to turn on super bright lights. This is very convenient and the battery life with this kind of use permits for going weeks without needing a recharge. Highly recommend. A no-brainer at this price point!
