Davide Groppi, 2010 Metal Recessed ceiling lamp Nulla is an extreme work on subtraction. The light is investigated and presented in its pure physical aspect. The research into a “light without a source” drove me to consider the realization of a project which is invisible, magic and illusive. A very simple idea: a hole in the ceiling. A 18 mm hole only, a special optical system and the LED technology make a wonderful light on the surface. Deep and sensual light. Compasso d'Oro ADI 2014. 1050 mA DC LED 12 W - 1350 lm
