This is an outstanding three piece set of antique nautical wall mounted ship lights. When mounted to the wall these antique nautical brass wall mounted ship lights will each extend out by about 6 inches. The junction box on the back is about 4 1/4 inches wide. These antique nautical brass wall mounted ship lights measure 10 1/2 inches tall (measured from the top of the junction box to the bottom of the globe cage). To access the bulb, you spin off the cage and the glass globe. Each light weighs about 8 pounds and can be used for interior or exterior lighting projects.
