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;

7. Advertising lights: UL48;

9. Night light: UL1786;

10. Emergency light: UL924.

Information required for UL certification of LED lamps

1. The model name will eventually be displayed on external websites and UL reports;

2. If there are multiple models, a description of the differences between the models is required;

3. The product manual provides specific use and installation environment, including how to wire. The installation environment usually includes three environments: DRY, DAMP, and WET. In WET environment, the requirements for the plastic shell of the lamp are different from DRY, DAMP, and UV-resistant plastic needs to be selected;

4. The UL file number and model name of the LED driver (FKSZ), plastic discharge fireproof enclosure (QMFZ2), and terminal blocks;

5. The layout of the LED circuit board of the lamp, the BOM of electronic components (each electronic component needs at least two electrical parameters) and the circuit schematic diagram;

6. The label of the lamp and the position of the sticky body;

7. Dimension drawings of the lamp housing.

LED lamps UL certification test items

1. Input test;

2. Lamp cap gauge test;

3. Torque test of lamp holder;

4. The tensile test of the lamp holder;

5. Drop test;

6. Dimming test;

7. Stress relief test;

8. Temperature rise test;

9. Abnormal short circuit test of components;

10. LVLE output test;

11. Rain test (need to be done if the bulb is used in a place exposed to rain);

12. Tide test;

13. Withstand voltage test;

14. Leakage current test;

15. Durability test (If the lens and the housing are fixed by glue instead of mechanically, you need to do a durability test for about half a month; or directly use special UL certified glue to fix it.

LED lamps UL certification process

1. Project determination

Confirm the UL standard, certification cost and time, number of samples, etc. based on the test

2. Data preparation

According to UL requirements, the company prepares all the materials or documents required for certification;

3. Sample delivery test

Enterprises send samples to designated laboratories for product testing;

4. Issue report

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.
