Potence Lamp (1950) 

A collaboration with Charlotte Perriand, this space-saving lighting solution suspends an incandescent bulb above a room via a nearly seven-foot metal rod. Considering it was created for the Maison Tropicale, a prefab housing unit meant to be manufactured in France and assembled in Africa, the small profile makes sense. The lamp can be adjusted and aimed via a wooden handle.
