Even after you've installed energy-efficient LED lightbulbs, you can still save more energy and money at home. For light fixtures that are on for the majority of the day, replacing a standard switch with a dimmer switch can mean saving around 4 to 9% in energy costs for that fixture. The more you dim, the more you save. Today's LED bulbs are designed to work with dimmers in the same way old-fashioned incandescent bulbs once did. By replacing light switches with dimmer switches, an average house can recoup about 20% in lighting costs per year.
