The structure is composed of two parts: the cylinder attached the wall or the ceiling and the spotlight, with a length of about 18 cm, formed by an extruded aluminium module. The two parts are connected by a mechanical joint that allows the light source to bend and rotate on the central base, adjusting the direction of the light. This freedom of movement makes Doi wall/ceiling extremely versatile and ready to respond to any installation requirements: a reading lamp placed by the headboard of a bed, or a perfect solution to light a corridor or a museum display, when attached to the ceiling or along a wall.
