Poul Henningsen's legacy in Danish lighting design is so significant, simply "PH" suffices. His revolutionary three-shade system, conceived in 1925, transformed residential illumination through scientific precision. The PH 4/3 Pendant showcases this mastery: three metal shades with a commanding 40cm top shade, positioned along logarithmic curves to cast soft, diffused light downward while eliminating harsh shadows and glare. Launched in 1966, this pendant's substantial architectural presence commands attention in any interior, delivering the warm, ambient glow that has distinguished discerning homes for nearly a century. Bulb (not included): 15W A-19. Made in Denmark.
