Why does the RGB strip glow when off?

Question

Electronics

Connection: Apeyron 03-47 power supply > Wi-Fi Smart Life module > RGB Tape.
Turns on / off and adjusts the color and brightness from the smartphone smoothly, everything is as it should.
But in complete darkness you can see how the tape glows.
When the TV is on, the tape is not visible, but when it is completely dark, the tape can be seen very well, it is impossible to sleep.
How to fix?

Answer 1

I saw this if the switch breaks the wire with ground / zero and not with phase. If there is only one wire power connection, the circuit receives parasitic currents through induction and capacitors. When transferring the switch to the side of the supply line, there is no such interference.

Answer 2

Control the power through the thyristor.

Answer 3

This is due to the fact that voltage is coming to the tape. It is necessary to get rid of excess voltage.
Is there a capacitor that will put the excess voltage to go to the load
