The Konkylie ceiling lamp was designed by Louis Weisdorf and produced by Lyfa in Denmark during the 1960s. The gold-colored blades have an orange interior, which produces a warm glow. They are installed in such a way that you never look directly into the light source. The lamp comes with a new gold-colored cotton cord.
