The Troy Lighting Elements Calla Exterior Wall Sconce is finished in Texture Black, crafted from steel, wet-rated for outdoor use. Strong and bold, Calla's simple form is wrought with complex design elements. Part of the Troy Elements collection, Calla is crafted from an exclusive EPM material that can handle UV and salt exposure for years to come. The elongated c-bracket features two exposed grooves that house bright LED boards. The result? Indirect light that washes beautifully against the wall.
