      Author:中認聯科 time:2020-12-24 Ctr:1749

      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.

      Common standards for UL certification of LED lamps

      1. Fixed lamps: UL1598;

      2. Mobile lamps: UL153;

      3. Low-voltage landscape lights: UL1838;

      4. Battery light: UL1576;

      5. Plant lamps, garden lamps: UL8800;

      6. High-voltage track light: UL1574;

      13. Withstand voltage test;

      14. Leakage current test;

      The product test results meet the UL standard requirements, and the test report is officially issued;

      5. Factory audit

      UL will conduct the first factory inspection of the production plant to ensure compliance with the standard requirements;

      6. Use of logo

      After the audit meets the requirements, the applicant is officially authorized to use the UL mark.
