According to reports, the output of LED lighting in China reached 180 million in 2011. The data for 2012 has not yet been counted, but in the first three quarters alone, the export volume of LED lamps has increased by more than 40%.
Peng Wanhua, secretary general of the Fujian Photovoltaic Industry Association and deputy head of the National Semiconductor Lighting Technology Standards Working Group, believed that although the current domestic LED lighting industry is developing rapidly, there are widespread problems such as low energy efficiency, short service life and high cost. Both have hindered the market penetration of LED lights.
"To make LED lights enter thousands of households, the price must be as low as the current price of energy-saving lamps." Peng Wanhua said that this is a very difficult goal, but it is not impossible, the efficiency of the lamps is put up, the cost is reduced. Down, the goal can be achieved.
Peng Wanhua said that in order for ordinary people to accept LED lights, the reliability and stability of their products must first be improved. The life of lamps is the main indicator of their reliability. "But now the domestic LED lamp can only achieve the life." 15,000-25,000 hours." Assuming that the lights are turned on for 8 hours a day, the life of an LED bulb is about 5-8.5 years. Peng Wanhua believes that compared with the life of LED chips and components, there is still much room for improvement in the life of LED lamps.
Peng Wanhua also said that the current energy efficiency of domestic LED lights is only 20%-30%, and we must find ways to increase the total energy efficiency to more than 50%, so that we can further develop the advantages of LED lights in energy conservation and environmental protection.
At the meeting, Peng Wanhua also mentioned the US SSL plan, which has set the cost of LED components to reach $2/thousand lumens by 2015 and $1/thousand lumens by 2020. According to the industry, LED lamps are composed of chips, LED components, heat sinks and lampshades. The cost of components accounts for about 1/3 of the cost of lamps. Peng Wanhua believes that this plan of the United States is also a cost target that is currently recognized by the industry. To achieve this goal, the price of LED components must fall at a rate of 20% per year in the next 10 years. 
A wall GFCI socket is different from conventional sockets. In the event of a ground fault, a wall GFCI socket will trip and quickly stop the flow of electricity to prevent serious injury.
Wall GFCI socket protect You From Electric Shock Due To:
1.With safe lock protection function,wall GFCI socket safety is improved.when miswired,wall GFCI sockets have no power and can not be reset,so it is more safe than conventional socket.
2.The wall GFCI socket includes end-of -life monitoring function,it can not reset correctly when the wall GFCI socket reaches the end of life.
3.Improved resistance to surge and corrosion.
4.Easier installation.(installation instructions enclosed)
The life of LED chips can reach hundreds of thousands of hours, and the life of components is also 50,000-100,000 hours. The LED bulbs currently available in China have a lifetime of only 15,000-25,000 hours. In the recent LED packaging and application products online testing new technology and new equipment exchange meeting, experts believe that LED lights to be popular, first of all have to live off.
