DALI-dimmable LED wall light One in ring form The LED wall light One consists of a ring made of aluminium, which is attached to a narrow, angular wall mount. The inside of the Ring is equipped with a continuous trunking light, which emits the light towards the centre and illuminates the wall. One thus visually embodies an atmospheric light image and impresses with its indirect lighting, which is carried into the room by Reflexion. When installed, the light colour can be selected using the switch behind the housing; warm white or cool white light is possible depending on requirements. The light output can be controlled via external DALI dimmers.
