Recently, the EU's Rapid Alert System for non-food dangerous products issued a warning on LED lights manufactured in China. Latvia was the EU member state that reported the issue. The warning reported Chinese LED lights can create high magnetic fields and potentially cause Electromagnetic Compatibility (EMC) interference. This violates the EU directive 2004/108/ EC which regulates EMC and also does not meet another related standard the EN55015. People have long been aware of the electromagnetic phenomenon EMC interference, according to understanding. 

EMC interference is created by electromagnetic waves emitted by certain electronic equipments that can easily interfere with other electronic appliances. In addition, overt electronic interference can form electromagnetic pollution that can damage people's health and ecological balance. Currently, many countries have issued EMC standards. In developed countries, equipments that fail to meet EMC standards are banned from sales. In response, China's General Administration of Quality Supervision, inspection and Quarantine (ASIQ) reminded related industries in China to pay close attention to warnings issued by the EU to consumers about Chinese lighting products. Secondly, companies should stringently abide to EU standards and regulations when designing and manufacturing products. 

Companies should also improve mass production technology, and even change their production model to avert losses from export trade risks. Especially in terms of the recent EMC interference issue, companies should strengthen product quality tests and audit whether key components contain potential safety risks, noted ASIQ. Companies should also seek support from third party testing organizations or technological support from ASIQ to guarantee exported products meet EU standards.
