First I want to say that on the luminosity of the headlamp is nothing to complain. What was really bad is solved, the hinge mechanism to the lamp to be tilted when the light angle to be adjusted. If you regularly use the lamp is this part made of plastic quickly worn and the lamp head is not in the desired position. In order for the head lamp is as such no longer usable. A request to this problem was not answered me by the manufacturer.
