Why Turn Off Mains LED Lights And Dim Peripheral Vision Occur?

Because switches control the zero-line distribution box when shut off after the zero line, FireWire current pass formed red power current sensing circuit, the power supply voltage to the LED power supply output section is a little weak, so weak peripheral vision.

At the time of installation, it is necessary to power the zero line and control switching and FireWire, if none of the conditions, it must be to the mains line switch control.
