Why Cheap LED Lights Keep Glowing
Why people recommend it
ElectroBOOM explains why cheap LED lamps glow faintly when switched off, through stray capacitance in the wiring, and shows a resistor fix across the rectifier output.
Watch for: the 470 kilohm resistor fix
In their words
Here's an exciting video by Electroboom demonstrating this effect:

The solution to the problem though is on another video by Electroboom saying to place a 470 kohm resistor on the output of the rectifier.
