LED prices would be equivalent to incandescent lamps in 2020

　　From January 1, 2014 , the United States banned the production and sale of 40 -watt and 60 -watt incandescent bulb , but before the ban took effect , many American families have a lot of this type of inventory traditional bulbs, so the next 75 watts and 100 watts traditional light bulbs will also become part of the banned products .

　　Driving under the federal standards and general lighting technology improved, making bulbs increased reliability , life expectancy is increasing , with more and better efficiency , general residential lighting energy consumption has gradually declined. Thus , although the higher initial purchase price of LED light bulbs , LED bulbs but high efficiency compared with conventional light bulbs more substantial savings .

　　Nevertheless, the majority of American families still believe that if replaced by LED bulbs 40 watts or 60 watts incandescent overpriced , so many families turn to buy fluorescent bulbs to replace incandescent bulbs, but the U.S. Energy Information Administration estimates, to this trend will change in 2020 , when the price of LED and incandescent bulbs will be very close.

　　U.S. Energy Information Administration believes in 2020 , LED bulb efficiency will reach more than 150 lumens per watt , lighting efficiency compared to traditional incandescent 60-watt output of 16 lumens per watt , almost 10 times higher . In addition , LED lamp life of up to 30 years , when the bulb will change the way people use behavior .

　　And between now and 2020 , due to the halogen incandescent lighting can be applied to general service standards, will continue to be used. But by 2020 standards continue to improve , halogen incandescent will face the fate of efficiency can not meet , so manufacturers must now focus on developing more efficient technologies.

　　LED bulbs in the future along with constantly updated technology costs down , perhaps to 2025 , the U.S. market will completely replace the bulb by a new generation of solid state lighting , this trend will blow the world become a trend.
