US Navy Westinghouse Searchlight Restoration Complete

The U.S. Navy Westinghouse 12″ Signaling Searchlight was commissioned in 1945 during World War II. Manufactured by Westinghouse Electric Corporation’s lighting division in Cleveland, Westinghouse signaling searchlights were used for day-time signaling between U.S. Navy minesweeper vessels when radio silence had to be maintained. This 12″ light uses a 100 watt incandescent lamp for a range that extends up to 5 miles, with a Westinghouse developed “Venetian-blind” shutter, capable of blinking 3 times a second. The searchlights were built to withstand a blast from 5-inch guns 20 feet away and a 200 pound weight dropped from a distance of 10 feet. These searchlights were constructed to resist salt-water spray and pass a “shutter test” which required a minimum of 2 million blinkings.

This historic U.S. military fixture was brought to Grand Light by a private owner to restore to working and aesthetic appeal, including rewiring, refurbishing mechanical components, and stripping existing finish to paint with an industrial grade enamel.

The searchlight was media blasted to remove the existing finish in preparation for multiple applications of industrial grade enamel.  A silver enamel was applied on the exterior while the interior, shutter, and base received a black finish.



Grand Light technicians installed new UL wet location listed components and added foam seal to ensure the searchlight’s internal components were protected from dust, dirt, and water.
