LED Lighting Basics

LED technology: changing the future of lighting Understanding the fundamentals of solid state lighting The light-emitting diode (LED), one of the most energy-efficient and rapidly-developing lighting technologies, has the potential to fundamentally change the future of lighting in the United States. That’s according to the Department of Energy (DOE), which also predicts that by 2027 widespread use of LEDs, also called solid state lighting, could save the equivalent annual electrical output of 44 large electric power plants (1,000 megawatts each), and a total savings of more than $30 billion at today’s electricity prices. “The potential of LED technology to produce […]
