Graphic and organic outlines harmoniously unite to accentuate one’s open-air walls with the Lina Esterno LED Outdoor Wall Sconce from Allegri by Kalco Lighting. The clean corners of the modern or contemporary setting are ideal with this durable geometric metal structure. Its windows direct the eyes to the artisanal Firenze crystal diffuser that evokes a natural formation. An LED array casts lively highlights on the glass and introduces a calm ambient glow.
