How to Convert 12v Led Lights to 120v Step by Step Guide

Step 1: Get Some LEDs:

The first step to how to convert 12v led lights to 120v is getting some LED lights. You can purchase these either online or at a local hardware store – many people like Home Depot and Lowes for their quality home improvement materials. Make sure the LEDs you purchase are 12v instead of 24v, as those will function differently and will not be addressed in this how-to convert 12v led lights to 120v.

Step 2: the Led:

The next most important part is how many LEDs you want. Be sure that the power supply that you have can support however many LED lights you plan on using at one time. You can start with a 20 watt or 40 watts supply and add more as needed if your LED strip does not have enough power to run all of your lights from the power supply.

Step 3: Power Supply:

The power supply is how 12V of electricity gets converted to 120V of electricity. There are many different power supplies, but the most common ones used for led lights put out a very clean and pure sine wave. The only difference between powering your lights from a wall outlet and using a power supply is how you hook up the connections. Using the diagram above, the positive wire from your lights will connect to the red lead of your power supply, and the negative or ground wire will connect to the black lead on the power supply.

Using a Power Supply

Step 4: Soldering The Connections:

When doing any electrical work (especially with something like led lights), you should always use heat shrink and solder for a secure and lasting connection. Heat shrink is like electrical tape but made of rubber, and its purpose is to insulate the soldered joints from exposure to outside elements such as water, oil, dirt, etc. When you solder the connections of your lights, make sure that you only ever turn on the power supply while you are soldering to be sure that you have a secure connection. Solder the positive wire from your lights to the red lead of your power supply, and solder the ground or negative wire from your lights to the black lead on your power supply.

Step 5: Resistors:

Now that you have the LEDs in the correct circuit, there is only one more thing to do. It would help if you had a resistor. David found a 150ohm 1/4 watt resistor was needed for each LED. You can get these at your local hardware store, RadioShack, or order them from us. Click here for resistors.

Step 6: One Led, No Resistor:

If you only have one LED and no resistors, we found that a 150ohm 1/2 watt resistor worked well for one LED, but anything over 75ohms may dim the LED.

Step 7: One Led With a Resistor:

If you have one LED and a resistor, we used three 150ohm resistors to power two LEDs.

Step 8: Wiring Up Multiple LEDs in Series:

David has wired up two LEDs in series for a 36-volt circuit.

David used three 150ohm resistors to power two LEDs connected in series. There is a resistor between each connection. The line coming from the battery goes to all of the negative connections, and there is a wire going back to the positive side of the battery. David found that putting a resistor on each line coming from the negative side of the LEDs and not ground worked the best as it took less wattage to power them (It is actually how we wire our 12-volt lamps).

Another option for wiring up multiple LEDs together in series is to use one 150ohm 1/4 watt resistor and solder it to the strip where all your LEDs are. If you want three LEDs in series, use two 150ohm 1/4 watt resistors and solder them together, so it is one long strip. Then connect both strips to the line from the negative side of the LEDs and run a wire back to the positive side of your battery.

Step 9: Wiring Up Multiple LEDs in Parallel:

The image on the right shows how David wired up two LEDs in parallel.

David used one 150ohm 1/4 watt resistor for each LED, soldering them both to the strip where all of his LEDs were. Then he connected both strips to the positive side of the battery and ran a wire from each strip back to the negative side of the battery.

David used one 150ohm 1/4 watt resistor for each LED, soldering them both to the strip where all of his LEDs were. Then he connected one wire from each strip back to the negative side of your battery, but this time on two different lines on the positive side of the battery. This way, you are powering each strip individually.

Note: if the resistor is on the line between LEDs, it does not have to be in line with how you are wiring your circuit.

If you want to wire more than two in parallel, just add another line from the negative side of your LEDs and one resistor for each strip.

Step 10: Extrapolation:

If you have more than three LEDs that you want to be hooked up in series or parallel, keep adding LED strips and resistors for each strip.

Go ahead to post your thoughts on how well these instructions helped! David also found it useful to draw diagrams of how he wanted the wiring done so he could get his ideas across better. You can draw how you want your circuit to be wired up on a separate sheet of paper and take a picture of it with your phone.

Will 110V LED Work on 12V

The answer to this question is not a simple yes or no. It depends on how many LEDs are in the circuit, how many volts the LED is rated for, and how many watts the resistor is rated for.

David found that if you have more than three LEDs in series or parallel, it is best to use a resistor for each strip. This way, you are powering each strip individually. If you have fewer than three LEDs, a 110V LED may work on 12V, but it is not recommended. Keep reading for more information about how to convert 12v led lights to 120v.
