Depending the shaped position, this lamp can lighten wall-, up- or downside. It can reach out to abouth 250 cm, but has in his smallest position less than 20 cm to the wall. The elements of this design are equipped with a hole. Through this hole all the components are held by a rod which is fitted at the ends of screw thread.
