Poul Henningsen's legendary PH 4.5-4 Glass Pendant Light by Louis Poulsen (aka PH 4½-4 or PH 4 1/2-4) features a large glass lamp shade with a diameter of 17.7 inches. The 4.5-4 fixture is designed based on the principle of a reflective three-shade system, which directs the majority of the light downwards. The shades are made of hand-blown opal three-layer glass, which is glossy on top and sandblasted matte on the underside, giving a soft and uniform light distribution.
