The Genius design has been doubled: Twin Genius, a totally recessed indoor luminaire for ceiling mounting, now available in its “Naked “version, extending the total surface integration concept to any material and surface.Fitted with two light emission holes measuring only 20 mm (0.79”) distant 95 mm (37.40”) one from another, the luminaire disappears completely when it is switched off, thanks to its total integration with the surfaces on which it is installed: wood, cement, mirror, marble and industrial modules with a thickness from 5 mm (0.2”) to a maximum of 20 mm (0.79”).The electronics retain the performances of the Genius, with the electrical part which can be removed through the light hole, thanks to a push-pull mechanism making it easy to pull the LED light source out and replace it, so there is no need for any inspection hatch, nor for invasive maintenance operations.
