Staff Sgt. Joseph Gessert, 341st Civil Engineer Squadron electrical systems craftsmen, replaces emergency lights in the fitness center March 13, 2017, at Malmstrom Air Force Base, Mont. Replacing fluorescent lights with LEDs will prevent the electrical shop from having to return to locations as often, save the base money in electricity and material cost, reduce energy use, and will help the Air Force with one of its priorities of balancing today’s readiness with tomorrow’s modernization.
