A variation on Poul Henningsen’s enduring triple-shade design, PH 4½-3½ Glass Table Lamp features a high-lustre chrome base and shades made of hand-blown opal 3-layer glass—glossy on top and sandblasted matte on the underside—giving a soft and diffused light. Based on the logarithmic spiral, light is distributed over the entire curve of the shade, which together with the reflection through the glass, makes it possible to control glare and shadow.
