The earth is the only place we can live on in the solar system.
How should we tread the only motherland?
We should be environment friendly.
But HOW?
The scientist invents some thing environment friendly.
LED is one example.
Its manufacturer should make sure it will work long time.
HOW do you and we know its performance?
We human being live from equator to high latitude. We experience rain, wind snow, sunshine.
The temperature and pressure changes dramatically in different region any time.
Can it perform well in different climate conditions?
The Most Common Test Standard is Double 85, so it can also be called Double 85 Test Chamber.
Wet high temperature operating life test has been used to evaluate the reliability performance of the LED modules. That is, the test at 85 C/85 RH is applied to LED module.
