Why does my 220V high voltage MR16 connector LED spotlight go up and burn out after one or two days?
At your age, the voltage is 220V or even slightly lower, the peak voltage is below the critical point, the breakdown voltage of the capacitor voltage is high so all right; now the hotel is close to 10%, the peak voltage just above the critical point, so the capacitor voltage, capacitance was penetrated. Two is the box, which ventilation is not good, the environment temperature is high, the lamp heat dissipation is not good, increased the capacitance leakage, it is easier to be breakdown. Just speculation, for reference only.
Because I do not know the specific parameters of your lines and components, so you can only be the speculation, there are two reasons: one is the estimated LED spotlight you is the capacitance of capacitor step-down, while the voltage is selected 250V.
