Ship lights used for illumination and navigation boast simple, durable design. As salvage, these lights are wonderful for use indoors and out, as a wall sconce in the bath or on the porch, as a table lamp, even as path lighting in the garden.
Once the fixture is rehabbed, you may need a shade; clear and frosted glass provide ample light. (You can always use a low-wattage or yellow or rosy-tone bulb.) For a table lamp, how about a shade crafted from a navigational chart, like those custom made by Skipjack Nautical Wares?
