Rings of metal are expertly soldered together to create a spherical frame for the bulb of your choice - incandescent, LED, or CFL. We love incorporating novelty bulb silhouettes or filaments for added interest, and one LED (as pictured) is included. Especially stunning in a breakfast nook or small room, with only a 15" depth, this is a semi-flush mount fixture that packs a lot of style into a small space.
