Harry Thaler, 2014 Edison’s Nightmare is the absolute novelty in 2014 by designer Harry Thaler for the brilliant lighting brands Davide Groppi. A reinterpretation of the classic light bulb Edison … hanging on the wall. At the Salone del Mobile in Milan in 2014, Davide Groppi presents this original and unsettling wall lamp, or rather, hanging on a nail. The style of Davide Groppi and its designer is unique, eccentric and punctual. A special perspective on lighting and the many variations of light. Davide Groppi and the real designer of light.
