Electronic kit for 5V USB-C battery lamps with threaded E27 lamp holder

This electronic kit for battery lamps is made for building a custom portable lamp, and it comes with a threaded E27 lamp holder in thermoplastic with a double ring. The round board, Ø 70 mm, takes a 5V USB-C input and gives a 5V output, while low-voltage fabric cables link it to the bulb, so the electronics stay apart from the light. The brass button, Ø 9.5 mm, houses a dimmer with three brightness levels plus off. The kit also includes M2.5x11 screws, a metal M10x1 rod, 25 mm long, with nut and washer, and a Ø 12 mm silicone adapter. Assembly needs no soldering, only a standard screwdriver; the 18650 Li-ion battery is not included.
