Monument to Thomas Edison switching from incandescent to LED bulbs

This summer, when the monument to Thomas Alva Edison on Christie Street reopens after two years of renovations, a small but symbolically significant change will take place. The 14-foot-tall glass replica light bulb on top of the 118-foot-tall tower will no longer burn with an array of incandescent bulbs, Edison's signature invention. The project calls for changing the lights to the new LED bulbs, a lighting-tech leap that came well after Edison's time. "Edison was all about innovation," said Kathleen Carlucci, the director of interpretation at Edison's museum in the town named after him. "This is just another innovation."
