The switch is also helping Boeing to continue reducing its energy use. From 2007 to 2012, Boeing saw its energy consumption decrease by 3 percent and is now focused on carbon neutral growth for its operations over the next five years, Warner said. In general, LEDs last two to four times longer and are 50 to 60 percent more energy-efficient than a standard halogen bulb, Warner said. And even though LED lights may cost more to install, they last much longer, which means fewer replacement changeouts are needed. And when the lights are on a tall factory ceiling, that’s a big benefit for maintenance personnel. Before LEDs, “all the light was coming straight down from the ceiling,” Warner said. “It didn’t scatter well and there were some very dark corners. The LEDs have a much better lighting pattern.” As another benefit, the LED lighting gives the appearance of being closer to daylight than other forms of artificial lighting. “It is more consistently bright,” Telford said of LED lighting. “It’s a bluer color that we see as white. And they spread the light out more evenly across the floor.” LED lighting also was recently installed in two production bays of the C-17 Globemaster III assembly line in Long Beach,
