Under normal circumstances, the outdoor floodlight has three wires, which are blue, brown and yellow-green.
When wiring the LED flood light, connect the blue wire and the brown wire to the live wire and the neutral wire respectively, regardless of polarity. After the wiring is completed, there is only one yellow wire left with a trace of green, also called yellow rolling green, which is the ground wire.
Generally, connecting the ground wire can lead the current to the ground, and it will play a certain protective role when the electrical equipment leaks or the voltage is too high. When there is a ground wire, it is best to connect it. If there is no ground wire, waterproof and leakage measures must be taken. Generally, a small plastic box is used to pack the wires wrapped with insulating tape together, and then seal them with glass glue.
Basic requirements for LED outdoor floodlight wiring: (1) Directly connect to 220v AC power with its own transformer. (2) If you don't have a transformer, check the voltage and power in watts, choose a transformer with the same wattage and voltage, connect the 220v transformer first, output 2 or 3 wires, and then connect the LED.
The wiring method of outdoor floodlight: the three-wire led flood light has both live wire and neutral wire, and a ground wire. It is the live wire and the neutral wire. Generally, the live wire is red, and the neutral wire is blue. The two wires are irrespective of whether they are positive or negative. Just connect to 220VAC.
