The processing of the lamp actually makes a pretty solid and sensible impression, only to a light arm I had to tighten the nut. The laying of the cable is properly carried out, but would have to turn out a little more compact assembly.
The only real drawback is the installation, the ceiling bracket is arranged obliquely to the lamp body and the lamp body is slightly pointed zuläufig on both sides. This situation makes it necessary that the bulb is first kept completely under the covers, then one can imagine the contours of the lamp, mark with a pencil and mark where the holder is screwed. Then you can fix any problem on the ceiling then the holder.
For final assembly, a second person should help so that you can attach the wires properly. It goes to the emergency but also alone.
