The Sonneman Tandem Wide Wall Sconce sets dual metal bars against the interest of a richly textural shade, making it an architecturally unique piece that flatters homes with a warm yet strong appearance. Great for adding a visual sense of width to walls. SONNEMAN - A Way of Light is the namesake of founder and lighting designer Robert Sonneman. It was formed to create contemporary lighting that best exemplifies today's cosmopolitan American style. Sonneman Lighting fixtures are elegant and refined, decidedly modern yet clearly influenced by classic 20th century period styles.
