The PH Artichoke Pendant is a designer Light fixture manufactured by Louis Poulsen. It was designed by Poul Henningsen in 1958. A chrome inner diffuser also assists in the proper even reflection of the light source. The light source can be an incandescent bulb (high powered halogen or xenon), fluorescent (with the ballast mounted in fixture canopy), or metal halide (canopy-mounted ballast). The metal halide sources are used in the largest of the Artichoke fixtures. For years, a number of companies have tried to replicate the Artichoke fixture; only a handful have made a replica that is at all geometrically and cosmetically similar.
