How to Wire led lights LED LightsWiring LED lights can be a bit tricky because of the accuracy demanded in circuit values and the number of LEDs in a typical lighting circuit. With LEDs, you need accurate values for current, voltage and resistance, or the circuit will not work at all. You also need to make a large number of clean connections using delicate parts as opposed to incandescent and fluorescent lamps, which require fewer bulbs and use lamps that are easy to connect to the power supply. Fortunately, the calculations are pretty straightforward, and LEDs are tough enough to stand up to soldering with little risk of ilure.

Wire the cathodes of each LED in parallel. Hook up each cathode to the common resistor. If each has its own resistor, wire each resistor to the positive terminal of the power supply.

Wire your resistor into the circuit. You can either use a resistor rated for the current of the total circuit and wire it to the positive terminal of your power supply or wire a resistor of the same value, but with a lower current rating, to the cathode the terminal near the flattened edge of each LED. For example, if the calculator tells you that your LED circuit needs a ohm resistor rated for watts, you can get one watt ohm resistor, or smaller, common ohm resistors usually rated for / watt.

Decide whether you want to wire your LEDs in series or parallel. In series circuits, the LEDs voltages are added. So, for example, if you have three volt LEDs, youll have a total voltage drop of volts. Since you need a power supply that is higher than the total combined voltage of the LEDs, wiring in parallel is almost always a good idea. If youre using only a few LEDs, however, you may want to wire in series for the sake of simplicity.

Keep your mily productive, connected, entertained, and safe.

Go to an online LED circuit calculator and plug in your values to determine what resistor you need. Click on the that says Parallel LEDs and input the voltage of your power supply, the number of LEDs youre using and the amperage and voltage of each LED. The calculator will tell you what resistor you need and the current rating that resistor requires.

Wire the anodes the other terminal of the LEDs to an SPST switch. Wire the other terminal of the switch to the negative terminal of the power supply. You now have an LED light circuit.

Note the specs of your LEDs. Commercially available LEDs have two values you need to be concerned with voltage and amperage. For the sake of simplicity, use LEDs that all have the same values.

Gather the LEDs that you want to wire into your circuit. Most LEDs require little power, so assuming you are using a decent power supply, you should be able to put in as many as you want.
