Upon their introduction in 1952, the Nelson™ Bubble Lamps® by Herman Miller® were an exciting collection of lamps that proposed a new kind of material application, using a soft plastic originally made for the military. The Nelson Ball Bubble Pendant is made of this material, which is vigorously spray-coated around a steel wire frame to make the round shape. The slightly visible wire frame is integral to the design, which ultimately creates soft ambient light once lit.
