Ph 4½-4 pendant designed by poul henningsen for louis poulsen. The lamp is made with hand-blown three-shade screens in white opal glass and chrome suspension. The model has a top shade of approximately 45 cm and uses the lower shades from the ph 4/4 series, developed to provide wider light distribution when hung low above a dining table or tabletop. The current version was introduced in 1980 and is part of the iconic ph glare-free lighting system. — origin: denmark — designer: poul henningsen — manufacturer: louis poulsen — model: ph 4½-4 — material: white opal glass and chrome — type: pendant — dimensions: h: 45 cm, dia: 45 cm — condition: presented in good condition this piece is attributed to the mentioned designer/maker.
