The processing of the lamp is very good, but the attachment mechanism is not very successful. On the one hand the screw for the bracket could be a bit longer and then it would be good if the lamp securely locks when pushed and not only when you press the small lever. With the brightness and burn time I am very satisfied, because there is nothing to complain about. The cone of light I find a bit strange, anyway, he is not as shown on the packaging. What I also did not realize why I have a small rubber cover (which is included) had to stick to the lamp up with adhesive pads. This would have been able to take place during manufacture. With the miniature guidance could the sense of this part at any rate not seen.
