4½" diameter and 11¼" tall. Includes a half gallon Mason jar with no bottom. Use these for higher wattage bulbs such as 40 or 60 watts. Shown with a 40 watt vintage bulb, not included. With the open bottom and ventilation on the top, these provide plenty of light while keeping everything cool. Our pendant lamps 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. Use it as a ceiling mounted pendant light with our optional Pendant Lamp Canopy kit.
