Dimmable modern pendant crafted of steel, aluminum, and glass  Poul Henningsen developed the PH 5 in 1958 in response to constant changes in the shape and size of incandescent bulbs, creating a lamp that could be used with any light source. The iconic design is based on the same principles as Henningsen’s three-shade system, which ensures that the light is soft, pleasant, and completely glare-free, making it the perfect dining room table lamp. The fixture provides a comfortable, glare-free light based on the principle of Poul Henningsen’s reflective three-shade system, which directs the majority of the light downward. It emits a lateral light as well as illuminating itself, providing a soft radiance from within its core. The lower shade is fitted with a frosted glass diffuser to ensure that the downwardly directed light is 100% glare-free.
