The PH 3-2 1/2 Outdoor Wall Sconce (1927) utilizes tiers of stainless steel shades to recreate a petroleum lamp's soft glow, with designer Poul Henningsen having experimented with the metal rings' size, shape, and position to achieve the desired effect. Matte white undersides project light downward and lend it an even, warm quality. Part of the PH 3-shade family. Bulb (not included): 100W/A19/E26. UL Listed for use outdoors. Made in Denmark by Louis Poulsen.
