Our light includes a half gallon Mason jar with no bottom. Our pendants include it all: 15½ 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. Requires a standard light bulb, not included. 40-watts is the maximum suggested bulb wattage for this item.
