Cassio BLK 4 Light Semi-Flush in Matte BlackStrong, industrial lines and a unique geometric design are the basis of the Cassio series. Dramatic, double edges and bold lines make Cassio a focal point that is sure to add visual interest to any space. As if frozen in space, exposed lamps sit within suspended 3 dimensional cubes. The open, glass free cage lends an airy, playful tone while providing utility in the form of widespread light and easy bulb changes.
