Louis Poulsen PH 4½-3½ Glass Table Lamp

The Louis Poulsen PH 4½-3½ Glass Table Lamp, a creation of Poul Henningsen, encapsulates the innovative three-shade system designed in the mid-1920s. This lamp, part of a broader family that has grown to 30 lights, including outdoor variations, is a hallmark of Henningsen's dedication to producing glare-free, directed light that enhances any space it inhabits. Initially developed in collaboration with Louis Poulsen, this design philosophy aimed at creating soft shadows and an evenly distributed light, has become a cornerstone of lighting design.

Transitioning from metal to glass shades, the PH 4½-3½ model not only directs light downwards but also adds to the ambient light of a room, a testament to Henningsen's forward-thinking approach to lighting. The lamp's design is based on the logarithmic spiral, ensuring an even distribution of light and minimizing glare, a technique that was revolutionary at its inception. Available in various configurations to suit different environments, this lamp, reintroduced in 1990, remains a versatile and timeless piece, reflecting the blend of functionality and elegance that characterizes Henningsen's work.
