Some industry experts predict that within 10 years, these lights will deliver more environmental and economic benefits than any other clean technology, including high-voltage power transmission, electric vehicles, smart grids or renewable power.

In North America,LED high bay light account for about 8 percent of the general lighting market, according to a 2012 report on the global LED sector from consultants McKinsey.

The use of these lights in the United States alone has saved 2.6 terawatt hours of power per year, equivalent to the electricity needed to power over 200,000 average U.S. households, according to a 2011 research report prepared by Navigant Consulting Inc for the U.S. Department of Energy.

In China, the world's top energy consumer and carbon emitter, general lighting accounts for 12 percent of annual electricity consumption. About 70 percent of China's electricity is generated from coal.
