PH 5-4½ pendant lamp

White

PH 5-4½ pendant lamp from Louis Poulsen features three aluminum shades primarily directing light downwards, along with an additional top shade with a trumpet-like appearance that illuminates the area above the three lower shades. The fixture, developed in 1984, is also equipped with a bottom bowl and a glare shield that makes it completely glare-free from all angles. The shades are coated with a matte, white color on the inside, which provides high light comfort. The iconic three-shade system was designed by Danish Poul Henningsen who, in collaboration with Louis Poulsen, created the first PH lamps in 1925-1926 for an exhibition in Paris. Here, he has utilized a scientific perspective as the lamp is constructed based on the logarithmic spiral, a mathematical spiral curve that occurs in many places in nature. This achieves an even distribution across the entire curve of the shade. In 1931, the four-shade system was then launched to increase the amount of horizontal light, which provides more illumination on walls and shelves compared to the three-shade lamp. The numbers on the PH lamps refer to the sizes of the shades and the letters are derived from the designer's initials. The brightness can be dimmed via a wireless Bluetooth connection from a tablet or smartphone. Feel free to explore the wide range of PH lamps.
