In 1975, Vico Magistretti seemed to take up a sort of unconscious challenge with Joe Colombo who, a few years before, had designed "?" called "Halogen", for Oluce, a floor lamp supported by a slender rod and a head designed to accommodate a powerful halogen bulb. Vico had the very same brief: the result was the "333" model, called "Dim". This was also supported by a thin rod (the power cord is initially outside), but with a reflector shaped according to a double wave. This poetic “gull-wing” profile, initially surprising in a fixture with a functional matrix, actually characterised Dim forever.
