Plaff-On Wall Lamp/Ceiling Lamp Ø50 IP54 Black is a ceiling/wall lamp, the beauty of which lies in its clarity and simplicity, not to mention its ability to provide various light effects. The lamp is made of blown white glass and has an outer aluminium lampshade with a white inside that reflectors the light. As the lamp is placed slightly removed from the ceiling/wall, the light is filtered upwards, creating a lovely glowing ring of light around the lamp.
