Poul Henningsen designed a revolutionary 3-shaded pendant back in 1925 and its many thoughtful variations even extend to an outdoor PH 3/2½ Bollard. The vertical lamp is designed based on the principle of reflection, with its spun stainless-steel shades having a matte-white painted interior surface which directs the majority of the light downwards, for a comfortably diffused, even glow.
