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.
