Yo-Yo LED wall light, warm white 2,700 K The Yo-Yo LED wall light is made up of two identical, circular aluminium plates with a coated surface, arranged at a slight angle. Between them is a diffuser made of PMMA. The light from the built-in LEDs is emitted radially through the diffuser, with the angled front plate creating an interesting light emission all round, which is more open at the bottom and narrower at the top. The special shape, which is reminiscent of the unforgettable and timeless yo-yo and is currently being patented, makes it an interesting lighting object on any wall.
