DALI dimmable LED wall luminaire One in ring form The LED wall lamp One consists of an aluminium ring which is attached to a narrow, angular wall bracket. The inside of the ring is equipped with a continuous light band which radiates the light towards the centre and illuminates the wall. Thus One optically embodies an atmospheric light image and convinces with its indirect lighting, which is carried into the room by reflection. During installation, the light colour can be selected using the switch behind the housing; warm white or universal white light is possible depending on requirements. The light output can be regulated via external DALI dimmers. Energy efficiency class:A+
