This report by the Duke Global Value Chains Center for the Environmental Defense Fund (EDF) explores light-emitting diodes (LEDs) for lighting applications. LEDs are a semiconductor technology whose application to general-purpose lighting is rapidly growing, with significant potential for energy savings. The market for general-purpose LED lighting is currently very small, but it is growing rapidly as the technology improves and costs go down. Leading U.S. manufacturers find it crucial to ensure high quality and to protect their innovations--two good reasons to keep the manufacturing close to home.
