SAN DIEGO - Petty Officer 1st Class Juan Diaz, a member of U.S. Coast Guard Aids to Navigation Team San Diego, carries a new light-emitting diode array to the Point Loma lighthouse in San Diego prior to installing it, Feb. 6, 2013. The LED system is brighter, uses 96 percent less energy and requires less maintenance than the incandescent lantern it replaced. U.S. Coast Guard photo by Petty Officer 1st Class Henry G. Dunphy.
