This aluminum wall light with cover and junction box measures 12 inches tall, from the top of the junction box down to the tip of the cage.  The aluminum rain cap cover that we added measures 8 inches in diameter.  When mounted to the wall, this light will extend out by 11 inches.  The junction box on the light measures 4 3/8 inches in diameter, and the two mounting lugs extend out and make it 6 1/4 inches.  The light weighs almost 3 1/2 pounds.
