I dont have acces to the project it self, but as an electrician I advice you to get stuff that follows your local code and when doing stuff with electricity be carefull and dont cut any corners. Its a strange thing you dont see it, feel it or smell it until it go’s wrong.
Now with the disclaimer out of the way, I would look for something with a E27 fitting, its the official name for the big screw fitting. E14 is the smaller version. You should be able to find it at your local hardware store.
If you got any metal parts on the lamp that could be put under power in case of a fault, I would also suggest grounding the lamp.
Just remember to be carefull and use the propper tools so you dont damage the copper wires.
I forgot to add one thing. Don’t know if Paul mentions this in his video, but when your hooking up the socket its good craftsmanship to connect the phase wire to the lip in the bottom and the zero to the screw tread where you screw in the light bulb. (see attached image)
This is done so when you screw in a light bulb the most dangerous part is furthest away from your fingers.
Thanks Joost. I ended up getting a kit at my local hardware store (I was surprised they had one.. it’s a small store in a small town), and it worked out ok. It’s not the greatest socket ever, but I can replace that later if needed.
