Domestic lighting products giant sunshine lighting (600261. SH) General manager Guan Yong revealed to the financial daily on December 14 that it is estimated that the number of domestic energy-saving lamps exported this year will reach 6. 6 billion, with an amount of 6. 6 billion US dollars; 3 billion incandescent lamps were exported, amounting to 0. 6 billion US dollars; LED bulbs and lamps are exported 3. 2 billion US dollars. He pointed out that although the number of LED lighting products exported was less than 5, the sales revenue accounted for 30%. Guan Yong also pointed out that there are currently 30 dealers in the major lighting cities in China selling LED lighting products. Some dealers can even Ship 100 thousand yuan of LED lighting products every month, but they often return them after 3 or 4 months, mainly because the life of LED lighting products has not exceeded 1000 hours. Guan Yong said that the high return rate of LED lighting products was mainly due to the lack of timely introduction of LED lighting product standards, and the development of LED products needed time to verify and could not meet the needs of market price competition. In addition, many dealers do not understand the quality of LED lighting.
