The LED ceiling light mounted in the living room will turn on the light after the power is switched off
Micro bright almost no power consumption, the impact on the lamp belt life is not great. However, this may indicate a problem with your switch or wiring. For example, a double switch (that is, two switches), or a small light on the switch. The leakage current of ground wire is large, and the problem of power supply design is likely to cause this phenomenon.

Power consumption can be ignored, it will not affect the life of the lights, but this is a potential security risk, your lights or switches have a slight leakage, for long-term safety considerations, I suggest you put this fault out
This phenomenon generally occurs in the product of large LED lamp, because there are dozens or hundreds of small LED, each voltage is about 3V, so the manufacturer of cost and technology, using electricity through a simple RC buck half wave rectifier followed by dozens of series. While the general household lamp lamp switch is SPST also, just cut off the line, 0 lines still attached, however, is only relative to the 0 line is the 0 line potential, but not really with the land or buildings with potential 0V, induction voltage plus long lines to bring, although only a few tens of volts, but the current is very small, not enough to make people feel, but a small circuit board in the lamp on a little leakage situation, let led make a fluorescent or can. This is a bit difficult, mainly from the start: for single pole double throw switch, discharge resistor circuit board in the lamp on the 220V line parallel 470k-1M Buck, limiting capacitor to parallel such resistance, also not in the two 220V lines are respectively connected with two resistance to the lamp shell, electrostatic discharge sensed. All of these will generally take effect, but not the people do not understand the electronic hands, not a bit fluorescence well, as a free good lighting, the lamp life didn't influence.
