    Author:中認(rèn)聯(lián)科 time:2020-12-24 Ctr:1359

    The necessity of applying for UL certification for LED lamps

    In the lighting industry, UL standards are equivalent to American national standards. UL is an important setter of American national standards, and 70% of the standards formulated have been adopted by the U.S. government as American national standards. For example, the UL 1598 standard-here UL is synonymous with the standard, which is equivalent to the meaning of GB.

    For UL-certified products, American buyers will have many preferential policies when buying insurance, so they will require sellers to apply for UL certification. In addition, the U.S. Federal Regulations "Electrical Engineering Law" also clearly requires related products to pass UL certification.
