Our Pulldown Pendant Canopy, included with this lamp allows for easily adjusting the lamp height. We have included 7' of fabric-covered lamp cord to allow installation on even higher ceilings. Installing on a standard 8' ceiling? No problem, just pull unwanted extra lamp cord through the canopy, effectively shortening the cord. Shortening the cord increases the height of the lamp when fully raised and when fully lowered. Simple instructions are included. Lamp measures 4" dia. and 10" tall. Canopy is 6" dia. Includes a quart Mason jar with no bottom. Use these for higher wattage bulbs such as 40 or 60 watts. Shown with our 40 watt vintage bulb, not included. with the open bottom and ventilated top, these provide plenty of light while keeping everything cool.
