LED energy efficiency certification

1. The damage rate of 6000 hours is greater than or equal to 0.9 (since the test time is long, the requirement will be implemented from March 1, 2014);

2. The luminous flux maintenance rate of 6000 hours is greater than or equal to 0.8 (since the test time is long, the requirement will be implemented from March 1, 2014);

3. Before failure, the number of switching times is greater than or equal to 15000 (rated life 30000 hours) or greater than or equal to half of the rated life calculated in hours;

4. The starting time is less than 0.5 seconds;

5. It takes less than 2 seconds to reach 95% luminous flux;

6. The early failure rate is less than or equal to 5.0% (normal lighting for 1000 hours);

7. The color rendering index is greater than or equal to 80%, and the color rendering index for outdoor or industrial use is greater than or equal to 65%;

8. The color tolerance is less than or equal to 6dB;

9. Power factor requirements: power less than or equal to 2W, no power factor requirements; From 2W to 5W, the PF value should be greater than 0.4; 5 w to 25W, the PF value is greater than 0; The power is greater than 25W and the PF value is greater than 0.9.
