●
The testing is operated at 25°C
●
The lifetime of capacitor, minimum of 5,000 hours if operated at 105°C, will be doubled whenever the temperature drops 10°C.
Working at 75°C or below, the lamp can achieve its maximum lifetime of 40,000 hours.
●
The highest withstand temperature of IC, MOS could be 120°C
●
The highest withstand temperature of LED junction temperature is 150°C
