The 1800 mm long frame of the lamp’s arc is made of metal and plastic, which makes it possible to mount it on the ceiling or on the wall (lay-on mounted). Soft diffused light of two LEDs, which are in the cover plates of the mounts, light the arc, creating the same "smile" design. You can create your own compositions in the interiors of several lamps or controlling the on-off of the certain lamps through the lighting scenarios.
