When Sonja Zozula and Jerry Anderson founded LightSaver Technologies in 2009, everyone told them they should make their emergency lights for homeowners in China. After two years of outsourcing to factories there, last winter they shifted production to Carlsbad, Calif., about 30 miles from their home in San Clemente. "It's probably 30 percent cheaper to manufacture in China," Anderson says. "But factor in shipping and all the other B.S. that you have to endure. It's a question of, 'How do I value my time at three in the morning when I have to talk to China?'"
