U.S. Energy Information Administration believes that the efficiency of household LED down light and other indoor LED lights will reach more than 150 lumens per watt by 2020, which is almost 10 times higher than the16 lumens p er watt that is the lighting efficiency outputs of traditional 60 -watt incandescent. In addition ,the lifespan of LED lamp will up to 3 years ,the behavior that people use the bulb will be changed.
The halogen incandescent lighting due to can be applied to general service standards will continue to be used until 2020. But the standards continue to improve by 2020 , halogen incandescent will face the fate that the efficiency can not meet , so manufacturers must now focus on developing more efficient technologies.
With the technology updated and costs of household LED down light and other household LED light in the future constantly cut, perhaps the U.S. market will completely replace the bulb by a new generation of solid state lighting by 2025 , this trend will blow the world and become a trend.
