Authentic nautical lights can not only give your project that desired coastal living look, but they will also give you functional lighting that will last. This original vintage Hallborn brass nautical light is a little less than perfect. It measures about 9 inches long from the back of the mount plate down to the tip of the cage, and will extend out from the mounting surface by about 7 inches. The back mount plate measures 5 1/4 inches wide, from one mount hole over to the one on the opposite side.  We have installed two brass plugs in the original conduit holes on either side of the light.  The cage spins on and off with just a little effort.  The glass globe just lifts off.  This vintage Hallborn brass nautical light weighs almost 5 pounds.
