Plugs into any wall outlet. Shown with our 40 watt vintage bulb, not included. Our pendant lamps include it all: 15.5 foot cloth-covered lamp cord with switched socket, two finished ceiling hooks, two cord clamps for adjusting the height of the lamp, and easy-to-follow instructions. Add our option of pulleys for a really nice industrial look. These lamps plug into any wall outlet; no wiring required.
