Efficient lighting goes beyond the bulb, with simple control systems that help save energy with little notice by the homeowner.
Switched motion sensors or dimmers should be used with any remaining fixtures that still use incandescent sources; they also can be used with energy-efficient sources. Switched motion, or vacancy, sensors must be manually turned on, but they automatically shut off after a period of time with no motion in the room. Dimmers save a percentage of energy slightly less than the amount they are dimmed, for both incandescent and fluorescent sources (i.e., dimming a bulb 25% saves about 20% of the electricity). Energy savings from dimming LEDs is variable.
Whole-house, intelligent lighting systems allow builders to automate a home’s lighting controls by setting lights to automatically dim 10% or 15%, or allowing homeowners to shut off all of a home’s lights with the push of a button. Lutron has a control system that includes a “green” button that trims light levels down throughout the home.
