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 2/1 Stem Fitting showcases this mastery: three handblown opal glass shades positioned along logarithmic curves to cast soft, diffused light downward while eliminating harsh shadows and glare. This pendant's architectural presence commands attention in any interior, delivering the warm, ambient glow that has distinguished discerning homes for nearly a century. Bulb (not included): 3 x 10W G16.5. Made in Denmark.
