The Nelson Ball Wall Sconce, a spherical shade hung from a walnut wall mount, will warm any interior with soft, diffused light. A swivel hinge allows for adjustment from left to right and up and down. Timeless Nelson Bubble Lamps were designed in 1952. The Bubble Lamp wall sconce is made with a 2-inch thick walnut wall bracket and a steel arm with a brushed-nickel finish that extends approximately 14 inches and an adjustable plug-in cord that's 12-feet long. The sconce arm has a swivel hinge and a counterweight, which allows for adjustment from left-to-right and up-and-down without having to change its position on the wall. Each shade is formed from a steel frame and a polymer covering.
