Often said that these lamps are from the 1970s, but they are not. Mario Bertorelle designed several lamps and they are all patented in between 1987 and 1992. They have names such as Proteo, Ellisse, Delta, Delfino and the Disco table lamp.

The Tuscan company J.M. – R.D.M. Srln was founded in 1979 as a manufacture of articles in plastic materials. It was first named JM Illuminazione and was founded by Mario Jannuzzi (JM).

J.M. – R.D.M. Srln ended business around 2012. Today (2019) a supermarket “Alì Supermercato” is located at the address.

For the moment no information to be found about the designer Mario Bertorelle, unfortunately.
