Poteau beton avec luminaire LED (Concrete pole with LED luminaire)

Height Total: 128mm Lamp Height:100mm For LED wiring, use preferably a white 5mm LED. Bend legs at 90° to solder to copper wire. Copper wires used come from the coil of a transformer recovery. I recommend passing the wires one by one through the bottom of the pole and rising to the 14th hole. Then, with a fine curved point, guide the end towards the curve of the lamp console (see photo). This part is originally covered with an insulating varnish; it will be sufficient to heat the extremity with a brick to be able to solder it to the LED afterwards. Under the plate, an 820 ohm resistor will be installed and soldered in series to one of the wires. Many examples exist on the internet for wiring a 12v LED.
