PH 3½-3 opalglass pendant lamp

Brass

PH 3½-3 opal glass pendant lamp from Louis Poulsen is a beautiful ceiling light. The shades are made of reflective mouth-blown opal glass in three layers that direct most of the light downwards. They are glossy on the outside and have a matte sandblasted inside that provides a soft and diffuse light. The iconic three-shade system was designed by Danish Poul Henningsen, who, in collaboration with Louis Poulsen, designed the first PH lamps in 1925-1926 for an exhibition in Paris. Here, he has used a scientific perspective as the lamp is based on the logarithmic spiral, a mathematical spiral curve that appears in many places in nature. This results in an even distribution across the entire curve of the shade, and together with the diffuse reflection through the glass, a harmonious and glare-free light is created. The numbers of the PH lamps refer to the size of the shades, and the letters come from the designer's initials. Feel free to explore the wide range of PH lamps.
