Ordinary household lighting (building), just connected the light is bright, is a little dark light, the switch is closed, I tried to take lamp to another building, light is no problem, family line which place is wrong?
Is most likely your switch with LED lights, so, after turn off the lights, LED indicator light on the switch, so, there is return current to the LED drive power supply, and you buy a lamp driver power supply, the design is not perfect, there is no partition backflow of electricity, so there is a faint light,
Switch to the zero line, should be a wire into the switch, do you have the leakage floor on a line, so it caused the leakage current, the LED can shed light on small electricity.
Switch is a wrong zero line, should be a wire into the switch, there would be no "jack-o '-lantern" broken wire
Should be your floor on a line where the leakage is!
