Light-emitting diodes (LEDs), a type of solid-state lighting (SSL), offers the electric lighting market a new and revolutionary light source that saves energy and improves light quality, performance, and service. Today, white-light LEDs are competing or are poised to compete successfully with conventional lighting sources across a variety of general illumination applications due to their ability to offer high quality and cost-effective performance. This book forecasts the energy savings potential of light emitting diode (LED), white-light sources compared to conventional white-light sources (i.e., incandescent, halogen, fluorescent, and high intensity discharge).
