Semi pendant light designed by Bonderup and Thorup for Fog & Mørup

Designed in 1967 by Claus Bonderup and Torsten Thorup and put into production by Fog & Mørup while the design duo were still students, the Semi proved an immensely popular light. An article in a 1973 edition of Mobilia magazine described the process by which each Semi was hand-produced. “A flat, lifeless sheet of metal is given one almighty thump by an automatic power press, surface-ground to produce an absolutely smooth texture and spray-painted to ensure a superior finish.” A Fog & Mørup catalogue recommended the use of a crown silver bulb with the Semi to achieve the optimum light distribution and prevent glare.

The Semi was one of just a handful of Fog & Mørup designs that continued in production after the company was taken over in the early 1980s by another Danish lighting company, Lyskaer, and the label still present in this example tells us that it was one of those produced under the Lyskaer branding during the 1980s before Lyskaer was itself taken over by Horn Belysning. The light has a diameter of 47 cm and a height of 23.5 cm and is in very good condition with minor light wear in the form of some small flecks of paint loss to the rim (see photos). It takes a standard Edison screw bulb (not supplied).
