My Idea that Works is to use light-emitting diode (LED) lamps, particularly for (Edison-screw base) direct replacement LED lamp applications, where applicable. In many applications, the results are quick and simple while providing a good return on investment. As LED lamp costs have come down and the quality and reliability have improved, the technology is quickly becoming the de facto standard for energy efficient and quality lighting. © 2015 Association of Energy Engineers (AEE).
