Poul Henningsen was the first person to pursue a scientific approach to light and use the logarithmic spiral as a basis. By creating a design based on the logarithmic spiral, he achieved even distribution of light over the entire curve of the shade. This even light distribution, together with the diffused reflection through the glass, made it possible to control glare and shadow. The 4½-4 Pendant in its current form was introduced in 1980. The elegant light source is perfect for hanging above a dining table or clustered over a work surface.
