PH 5-4½ Pendant Light By Louis Poulsen

The 5/4½, was created by Poul Henningsen for the Aarhus Concert Hall in 1984.
The trumpet-shaped top shade on the fixture provides illumination of the area above the three shades, which primarily direct the light downwards. A base reflector and a blue glare ring protect against glare from all angles.
The strongest light is directly under the fixture. The shades have a matt white painted finish to ensure very comfortable lighting.
