Use your own jar to create a lamp. Includes hooks, clamps, and a mason jar kit that will screw on any standard-size mason jar. 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. Jar not included. Includes 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. Light bulbs are not included.
