Zero FOG Steel pendant lamp

FOG is a pendant lamp by Zero.‎  With no apparent light source, Fog looks like a flaming planet, a mystical hovering globe.‎ The glass is blasted on the inside, graduated smoothly from completely covering the bottom to disappearing up near the metal socket, where the light source is well hidden.‎ Fog creates a new effect with classical materials and proven technology.‎ The light appears to shoot up from the bottom of the globe, emitting an ambient glow that rises like a magically fiery fog.‎ D 350 mm.‎ Further info from manufacturer on FOG Zero
