According to the U.S. Congress passed the incandescent ban , the United States will begin New Year's Day 2014 to stop selling the market 's best-selling 40 -watt and 60 -watt incandescent . The move aims to promote energy-saving compact fluorescent lamps , LED light bulbs and other energy efficiency higher . Notably , China, the EU, Australia and other countries also would expand the regulatory scope of the incandescent lamp from existing industrial areas to residential use with indoor lighting.Compared with incandescent lamps , LED lights on the advantages of energy-saving effect is obvious ; compared with the traditional one-piece fluorescent lamps , LED lamps have an advantage in environmental protection . In addition, energy-saving lamps contain mercury and other harmful elements , will cause serious environmental pollution . The LED lights do not contain mercury , its circuit board recycling easier than the energy-saving lamps , pollution of the environment is much smaller than the energy-saving lamps . It is understood that each energy-saving lamp mercury content of about 3 to 5 mg per 1 mg of mercury, 360 tons of water can be contaminated . In summary, the LED lights do not contain mercury , and in the life and energy efficiency can achieve good results, so the prospects are promising LED lights .LED industry, the latest market report that 2012-2014 , with all regions incandescent disable gradual fermentation efficiency , LED lamps began to enter the home lighting market. Because the luminous efficiency LED lamps and prices, consumer acceptance gradually enhanced , LED lighting market share increases. 2013 , home lighting market in China will reach $ 5941 million , growth of 36 %, including LED home lighting market will reach $ 814 million , an increase of 96% , is expected to account for 24 % of the world .
