An indoor and total disappearing luminaire of AirCoral®, Bell is installable on plasterboard or brick ceilings. It is characterised by an internal, rounded perimetral empty space creating a contrast between light and shadow, of presence and absence of matter. The backward light source casts a sharp beam which, at the same time, scatters softly both on the body surface and in the environment. Bell is a new typology of lamp whose personality is always visible, with the light switched on or off as well. This personality reflects itself in the surrounding environment too.
