The Callum Wall Sconce from Huxe frames a round opal glass globe within a circular metal ring, the two forms sitting concentrically against a flat, round backplate. The ring can be repositioned, shifting the globe's placement within the frame and giving the sconce a different look depending on how it is set. The opal glass diffuses the light source into a smooth, even glow, and the dimmable output allows that light to be brought up or eased back as the setting requires.
