When pressing of 2 bulbs in the Rings there were problems because the spot welded to the rings inside 3 straps are too long and thus the flap diameter compared to the bulbs is too small. By pressing the tabs with pliers to the ring, the problem could be solved, but this came on the outside of the ring Quetschspuren. This problem occurred when inserting the cover ring in the glass plate. Besides these difficulties makes the ceiling lamp a beautiful impression.
