"Wonderfully asymmetrical
Yo-Yo on the ceiling offers optimal glare control and a more pronounced emission depending on the chosen direction. Yo-Yo is composed of two equal, slightly oblique parts that enclose a radially emitting LED source, whose shape (under patent) is reminiscent of the unforgettable and timeless yo-yo. The result is a variable emission, more open at the bottom and narrower at the top."
