Designed in 1952, the Nelson Bell Bubble Pendant by Herman Miller were an exciting collection of lamps that used a new kind of material that had a surprisingly warm and comforting quality once lit. The material is a soft plastic, which is vigorously spray-coated around the Nelson Bell Bubble Pendant, a dome-like hanging lamp that creates perfectly diffused light. The Bubble Lamps are so emblematic of mid-century modern design that they are part of the permanent collection of the MoMA in New York.
