LED lights when there is a problem how to deal with

LED run for a dark, is the current through the switch power supply wire caused by too much, whether or not the current current sum check lead over the switching power supply output value. If yes, should replace the power supply wire and other LED accessories.
1, LED run for a dark, is the current through the switch power supply wire caused by too much, whether or not the current current sum check lead over the switching power supply output value. If yes, should replace the power supply wire.
2, LED just when power is very bright, after a period of time after suddenly not bright or brightness attenuation, can check whether the switching power supply is 12V LED misuse into 24V.
3, if no problem, then check the input voltage switching power supply is 220V if the LED brightness high or low: check that the input voltage and output voltage switching power supply is normal. Such as voltage high, cause LED damage; if the voltage is low, will cause the LED not bright or luminance attenuation. If the user where the voltage is not stable, may suggest the user install regulator.
