Bright Lights, Big Savings

摘要

Aquiet revolution is transforming lighting-a flick of a switch at a time. After a century and a half dominated by Thomas Edison's incandescent bulb, solid-state lighting is coming into its own, replacing a technology that is energy-hungry and generates far more heat than light. LED lights are gradually replacing the old lighting technology, and even fluorescent lighting, because of their tremendous energy savings, their long life, and their precision. Why? LED lighting, for one, is more energy-efficient than the alternatives; an eight-watt LED lamp will produce as much light as a 60-watt incandescent bulb. This significant energy savings is the greatest driver of the industry's growth as countries around the world have begun to ban incandescent lights and demand that consumers use LEDs to lower energy use.
