Since U.S. Department LED Downlights of Energy figures reveal that about 22 percent of electricity used in the United States goes toward lighting, converting to LED bulbs would have a profound economic and environmental impact.
DenBaars said that if 25 percent of U.S. light bulbs were converted to 150-lumens-per-watt LEDs, the nation would eliminate the need to build 133 LED Strip Lights coal-burning power stations and reduce carbon emissions in the atmosphere by 284 million tons.
However, the LED Strip Lights that are currently available fall way short of 150-lumens per watt. Such technology may be on the horizon as a couple of companies have developed experimental LEDs that can put out around 130 lumens per watt.
In DenBaars' 150-lumens-per-watt GU10 LED Lamp example, the United States would save about $115 billion by 2025 in utility costs.
"Multiply that by three and you get the worldwide savings," he said.
