The timeless model PH5 pendant lamp was designed by Poul Henningsen for Louis Poulsen in 1956. This lamp is probably a 1960's model with a spring socket. I has an equal faded blue (jeans blue) colored shade and a red circle plate for the socket and top shade. when taken apart some discoloration can be seen as the parts that have never seen the light of day are somewhat darker. This lamp is in a good and original condition with some signs of age and use.
