The ph 4/3 lamp is an absolute classic, designed by the renowned danish designer and architect poul henningsen. It has been manufactured by louis poulsen since 1966. The lamp's form is based on the same principle of a reflective system as other three-shaded lamps, including the ph 5 and ph charlottenborg lamps. This system directs light not only downward but also sideways, illuminating the lamp itself. Thanks to its design, the ph 4/3 produces a diffused, glare-free light with a warm tone. dimensions: diameter: 40cm height: 20cm the lamp is in very good condition, with minor signs of age. the lamp has been thoroughly cleaned, and the cable has been replaced with a new, braided cable. A new metal canopy is included. love vintage? check out 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, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
