Processing ok, price too expensive. The light is bright and not at least cool white. The propping of the wall units proved tricky because the lamp appears to be in one piece. The swiveling light bar is apparently not to be removed, but the holes for mounting are less. The bar is thus placed on the right angle, so that one then there can fiddle. In principle, I would have liked to open the housing. The power supply line on the side I also rather awkward because as a distance between the lamps is inevitable. In my case I have 3 lamps 57? Length 1900 mm side by side. Unfortunately no way to combine the lamps / sew together. For each lamp an extra outlet, 3 x 1800 mm Kabelei and each switch individually has also nix. So I cut off all the connectors, a terminal box to, switched from this again a connector, all lamps and a plug in a wireless socket, so I at your fingertips all on or off can. As a result, very good. Much of the lamps (housing) is now not to be seen, so it probably. a cheaper version would have done. Delivery time ok.
