The Davide Groppi Nulla plaster in downlight is an extreme work on subtraction. Winner of the 2014 Compasso D'Oro ADI, the light is investigated and presented in its pure physical aspect. The research into a “light without a source” drove Davide Groppi to consider the realization of a project which is invisible, magic and illusive. A very simple idea: a hole in the ceiling. A 25 mm hole only, a special optical system and the LED technology make a wonderful light on the surface. Deep and sensual light. The light is constructed from metal.

This downlight is available in Push, DALI and TRIAC dimmable versions. A plasterboard flange, which is required for installation, is also available. US version available - usually delivered in 4 to 6 weeks. For prices and further information please contact us. Delivery approximately 2-3 weeks for other versions.
