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. LED lights require half the wattage of currently used lights and also have a lamp life of 50,000 hours, nearly five times the life of fluorescent lights.
