A LED suspended or over-table luminaire with dimmer, for interiors with dual light emission and double switch: localized direct downlighting and indirect uplighting. On or more transparent methacrylate rings, each made up of 20 little cubes, rest on a load-bearing disc made of aluminium and stainless steel polished to a mirror finish, on which the LEDs are housed. Available in the versions from one to four crowns, and modular to create a light column with the height desired.
