From The Anvil Smooth Copper Brindley Wall Light - Elan Black Pedestal & Post Lights so there is no separateThis Brindley wall light is spun from solid copper in a smooth, polished finish and dressed in a deep, matt Elan Black, giving a directional fitting a bold, graphic look with warmth from the copper beneath. Once lit, the smooth copper produces a subtle, warm light best balanced with a cooler or brighter bulb. It suits hallways, staircases, or flanking a fireplace, particularly in darker schemes, and pairs naturally with the matching Brindley pendant.
