Electrical – How to install 230V Light with Light-activated-resistor

electricallightingsafetySecurity

I am trying to set up light-activated-resistors that activate a light during dark hours. I have bought a ready Chinese thing that apparently contain a driver to change from AC to proper DC output for the light but I I don´t know for sure. The fact that the cords connected to the Chinese white light-activation thing are so thin hints me that connecting them directly to the 230V sockets is not probably the best idea. I have hacked an old radio power cord (on the picture) but I am afraid to plug it to the device before proper understanding of the system. The house where I am experimenting has no earthed sockets so I don´t know how to try out this kind of devices, not wanting to fire up the house.

So how can I install the device? What kind of precautions should I have? Where and how I should try the device? If I can understand right, it requires AC in.

This leaflet just contains some general information concerning the product. The only thing relevant to installation is in point 5 (labeled 五).

Basically, the user is told to connect what are literally labeled as the "fire wire" and "null wire" (火线 and 零线) -which I interpret as respectively the red and the black wires- to an AC supply of 180 to 250V, 50 to 60Hz frequency, where the device should happily consume less than 60W of power.

This agrees quite well with what is on the bottom of the box.

This device does not need an earth connection, since the enclosure is plastic. Earthing is used when the container is metal, and the user could receive a shock if a live wire was touching the interior.

In addition, please note the timing seems to be able to be graduated, from 50 +/- 20 seconds.
