Arena is a circular luminaire that combines a classic form with the ability to reconfigure light sources by attaching them magnetically. A magnetic ring allows users to snap-on or snap-off light sources. Each light source is equipped with strong neodymium magnets that form a safe, low-voltage connection to the ring. Users can move, spread evenly, gang, flip up or down, pivot, or aim light sources without tools or an electrician. Light-source options include Slice, Aim, Beam, and Glow.
