Are there any criteria and standards for choosing a good LED lighting?


LED lighting in a developing stage of its technology, still does not have a standard of quality and performance. NPO, LED lighting Promotion Council in Japan, in the United States has NIST (National Institute of Standards and Technology), is aimed at standardization of the standards. The standardization has been preceded by the South Korea, "technical standards Institute" of Ministry of Knowledge Economy in March 2009 (corresponding to METI) and has issued the certification standards. Therefore, Korean "KS certification standards" will be a measure of choosing products distributed in Korea. In all cases, because now no JIS standards, and already LED lighting is on sale. However the reality of having "bad products" is also floating around cheap. Because reasons concerning electrical product, electromagnetic waves and, measures of over-current at the time of lightning, it is very important if there are measures of dust-proof and waterproof performance. Always before purchase, let's verify that the product been evaluated by the third-party organizations such as the Foundation for Electrical Safety & Environment Technology Laboratories (JET), PSE (Product Safety Electrical Appliance & Materials) and see their evaluation.
