Have you read Malcolm Gladwell’s longtime-bestseller The Tipping Point? In it, the author discusses the phenomenon where something goes from being marginal to mainstream. For LED (light-emitting diode) lighting, the tipping point has arrived. U.S. Department of Energy statistics show that about 49 million LEDs were installed in the U.S. in 2012 — saving about $675 million in annual energy costs. And, switching entirely to LED lights over the next two decades could save the U.S. $250 billion in energy costs, reduce electricity consumption for lighting by nearly 50 percent and avoid 1,800 million metric tons of carbon emissions. With benefits like these, it’s easy to see why the LED industry is rapidly expanding, and why commercial facilities, big and small, are turning to LEDs as their lighting application of choice.
LED is a type of solid-state lighting that uses a semiconductor to convert electricity into light. The Department of Energy says that today’s LED bulbs can be six to seven times more energy-efficient than conventional incandescent lights and can cut energy use by more than 80%. What’s more, the Department of Energy says good-quality LED bulbs can have a useful life of 30,000 to 50,000 hours or more — meaning they can last more than 30 times longer than traditional light bulbs.
