Seven, life test:

Target: LED lamps (finished lamps with LEDDriver)

Reference standard: industry experience

  Test Methods:

1. Test the initial luminous flux, power, color temperature and other parameters according to the rated input in 5 LED lamps at room temperature of 25 °C;

2. After the initial test is completed, place the samples in an environment with a room temperature of 25 ° C, and turn on the power according to the rated input voltage;

3. In the first three months, the samples were tested for the same environment and the same conditions as the initial test every 10 days. The optical flux, power, color temperature, etc. of the test were recorded and compared with the initial parameters.
