The USS Chafee (DDG90) has become the first US Navy ship to be fitted with all-LED lighting.  More than 600 LED lighting fixtures provide light for the guided missile destroyer based in Hawaii.  The Navy expects to save more than $50,000 per year using the new lighting system installed by Energy Focus Inc.

According to a post on the Armed with Science blog, Ben Hatch, an electrical engineer at the Naval Surface Warfare Center Carderock Division – Ship Systems Engineering Station in Philadelphia, who oversaw the installation, said, “The longer lifespan also results in a huge amount of savings in regards to maintenance.  LEDs last 50 times longer than the incandescent meaning the lights only need to be replaced every six years compared to what was every other month.”

The Naval Sea Systems Command plans on installing the fixtures aboard in combatant and amphibious ships over the next several years as part of the Navy’s maritime energy strategy.  The next ship up for the retrofit is the USS Preble (DGG88).
