The ph 4/3 lamp is an absolute classic, designed by the outstanding danish designer and architect poul henningsen. The lamp has been manufactured by louis poulsen since 1966 until today. The form of the lamp was designed based on the same principle of the reflective system as other three-shade lamps, including the ph 5 lamp, ph charlottenborg. This is a system that directs the light not only downwards, but also to the sides, while illuminating the lamp itself. Thanks to its construction, the ph 4/3 gives a diffused and non-glare light in a warm tone. dimensions: diameter: 40cm height: 20cm the lamps are in very good condition, minimal traces of use. it has a new braided cable and a new metal canopy. do you like vintage? visit our instagram @same.olds – you'll find lots of cool stuff there! this piece has an attribution mark, i am sure that it is completely authentic 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.
