The top shade is available as either mouth-blown opal glass or copper with a white inner surface. The copper top shade has a copper outer surface and a white inner surface that ensures soft, downward light distribution The glass top shade is made of mouth-blown white opal glass and provides more diffuse light. The two lower opal glass shades provide a larger lighting surface to make more efficient use of the light source. The glass shades are polished on the outside and matt on the inside. The downward light is both soft and pleasant.
