This is a Poul Henningsen's 1958 design based on the principle of a reflective three-shade system, which directs the majority of the light downwards. The PH5 lamp was launched in 1958: the 5 in its name refers to its 50 cm diameter. The shades are in white lacquered aluminum. The lamp is in perfect condition. The wiring has been replaced new. Lamp has been tested and is in working order. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
