During the day, the grooved texture of the opaque diffuser camouflages itself against wall, as its rectangular outline also does, simply “disappearing” into the background. In the evening, the Led lights reveal a translucent structure and emit a halo of light that surrounds it, appearing as if it is floating in the space. The compactness and the high performance light source along with utilization of light–weight materials allowed the different functions and elements of a traditional lamp (diffuser, bulb) to be concentrated into a single object.The lamp presents new illumination techniques that respond to the recent politics of energy efficiency, namely Italian legislature passed in December 2006 (L. 27 December 2006 n. 296) which grants tax deductions for up to 36% of the costs sustained to implement efficient solutions; or more internationally the EU decree that in 2012 will definitively eliminate incandescent bulbs from the market. ALA, small and sleek, maintains the dimensions of a A4 sheet of paper (29,7 x 21 cm) with a width of 2cm.The base of the lamp is fixed to the wall by a chromed stainless steel stem with a rounded head, a form that allows users to move and rotate the rectangular surface in order to obtain the desired illumination: direct, indirect or diffused.
