The Artemide Edge 21 wall / ceiling light, designed by Alessandro Mendini, is a wall and ceiling lamp that features a cubic diffuser made of technopolymer and a synthetic resin wall fixation. Emitting diffuse and dimmable light, this fixture is equipped with an IP65 protection index, making it suitable for both indoor and outdoor use. The missing corner of the cubic diffuser creates a unique visual effect, anchoring the lamp to the wall or ceiling and giving the impression of a cube protruding from the surface. With its strictly geometric yet dynamic design, Edge 21 seamlessly integrates into various architectural contexts, adding a touch of sophistication to modern spaces.
