What I like about the lamp that it is compact and versatile. I use them almost every day to jog, just as the days now are shorter .The light output is really very impressive. The light is very bright and evenly. The lamp is comfortable to wear and not hard (what you can not believe in this brightness). And precisely for this reason it is good that the headlamp has four Helligkeitststufen. Because when you walk on busy roads, the traffic could be blinded otherwise quickly at this high luminosity. Practically, I find that you can use the light not only as a headlamp, but also as a normal flashlight. (Included with this a clip is included.) So you have the lamp quickly tucked in his pocket and fix Ready. Just the fact that you have two very bright lights in a I am thrilled with the headlamp and can definitely recommend.
