Energy Efficiency of LEDs
www1.eere.energy.govThe energy efficiency of LED products is typically characterized using efficacy, which in basic terms is the ratio of power input to light output—or more technically, emitted flux (lumens) divided by power draw (watts).1 For such a simple concept, however, there are several important nuances that must not be overlooked.
