Derating Curve
1.To extend their life, please refer to the Derating Curve and derate according to the temperature.
2.Please note that the rise in temperature of LED fixtures over a long period of time will cause their power to rise.
Therefore, we recommend the power supply to reserve a certain amount of load to avoid overloading.
