Shady PIR ceiling light analysis. (With flame test.)
This light was sent by Miek (Me-Yack) after he bought it on eBay but wasn't sure about the wiring colours. In reality it's quite an odd arrangement. To get an earth/ground connection on the metal baseplate of these lights a separate earth wire and eyelet/fork crimp onto a case screw is probably best.
It's most likely the yellow wire is an override for the PIR sensor function. If you used a two way switch that toggled between the red and yellow wire it would switch between continuous-on and automatic mode.
The high apparent power when the light is off is due to the use of a simple capacitive dropper power supply for the circuitry that has to provide enough current to activate the relay. If your utility company charges for apparent power, as many can do with the smart meters, then it means this light could cost as much to run when it's off as when it's on. Not many utility companies do charge for apparent power yet, but it's going to be a thing in the future because.... profit.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
