The lamp operates at first glance processed high quality, it has a nice metallic coating. The light illuminates our house wall is not too bright, not too dark, just right. So far so good, would decide between four and five stars. But !!! When screwing I have my thumb and index finger cut strong bloody at the outer edge! The edge, which is the outermost ring is extremely sharp. Maybe there is a manufacturing defect, so it not looks, the edge seems to be designed. So I can only advise to be careful and unfortunately this place an mickerigen point.
I still get a same lamp from another dealer that I've looked at. It is by the same sharp edge. So that is a design flaw for me, so the lamp is unlikely to reach the market. It remains at one point due to acute injury.
