Quart Mason Jar Pendant Lamp in Rustic Brown Shown with an 11 watt sign bulb from The Home Depot. In spite of our ventilated lid, jars are small, closed spaces and we recommend a small light bulb with a low wattage for use with these kits. Includes a 15 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. 4 diameter and 11 tall. Light bulb not included.
