All started with free hanging lamp for plants, then I wanted to change old IKEA wall lamp with something else, few days and multiple iterations later it happened. initially all I had was lamp socket with threads for E27 bulb and LED Lamp E27 PAR38 Plant Light.

At the moment there are no Assembly guide, I suppose everything is self explanatory - if guide is needed - ping me up.

Was not able to add parts needed, so her's the list (just google it):
LED Lamp E27 PAR38 Plant Light
FE27PRB1 PLASTIC LAMP SOCKET E27, HALF-THREADED (bought in local store)
18AWG or1mm2 wire
