This wall lamp is simple but really nice and very stylish and scatters the light in a pleasant way. Installation is as already mentioned by other customers something knifflig.Man requires a narrow long screwdriver that does not leave marks on the edge of the plaster lamp. Somewhat unhappy I find the holes for wall mounting, the left hole is just above the opening for the cable entry. If now in the wall has a slightly larger hole or plasterboard walls, can be found at attach little support for the dowels. My somewhat unconventional solution: With a 10 mm wood drill I drilled a new hole for the cable running down the center of the back wall. Only pre-drilled with a small drill bit, then put ever greater. Through the soft plaster that's easy. Then also the wall mounting has again funktoniert easily.
Update: I have again ordered me 4 lights, at the latest delivery and mounting hardware (screws and plugs) was now in the process.
