An Art Deco twist for hallway wall surfaces. The Greco Wall Sconce from Eichholtz. Starting with a small metal structure that sets a curving bar above a single socket lamp, it retains smoothly curved glass strands in a layered, overlapping arrangement with a curving lower end and a cut-off upper end. The separate strands of stretched glass reduce the bright glare from the lamping, transforming ambient light into a stylish glow.
