Evolving from Poul Henningsen’s defining 3-shade lighting system with Louis Poulsen, PH Wall offers its characteristic glare-free illumination indoors or outside, providing direct light where it it is most needed enhanced by soft surrounding shadow-play. Debuting a century ago, the redoubtable multi-layer reflective design directs the light downwards, with the spun-copper shades having a matte-white painted underside to ensure diffuse, even light distribution.
