Gauge Wire for 12V LED Lights – Which Should We Choose?

12V LED lights come in different sizes. You can choose a small or large Gauge Wire for 12V LED Lights depending on the size of your project.

If you are going to install it outside then use a thick wire as it will be exposed to outdoor heat and sunlight. However, if you need it for decorative purposes then opt for a thin gauge cable.

The 12V LED Lights have a voltage range of 10-15 volts. The current that is drawn to power the lights are called gauge wire and it depends on how much light they emit.

Most times the size of the wire increases as we go down in voltage, but there are some occasions where more compact wires for higher voltages are used.

The gauge of the wire can be a simple measure of its thickness or diameter. A bigger 12V LED light will normally use more than one gauge fuse while a small one may not need any at all.

The low voltage lights are very safe and they do not pose fire hazards but that does not mean people can stop using them. Safety must be considered at all times.

The size of the wire should always be taken into consideration since it determines what kind of fuse to use and how much power can go through it.

You will find that 12V LED street lights are safer if they use low gauge wires since there are fewer chances to start a fire and cause accidents.

The main use of the 12V LED lights is to provide illumination but there are some cases where they also act as a floodlight in places like parking lots.

They have a good amount of illumination that makes them great for decoration. You can switch on the light when you want people to see something and switch it off when you no longer need it.

The feature is very convenient since it eliminates the need for someone to be there all the time. The 12V LED light bulbs can work automatically and that makes them efficient.

The more you look into LED Lights, the more you will see how many advantages they have over the older types of light bulbs. They do not give off much heat and that keeps the surrounding places cooler.

The light emitted from 12V LED lights is a soft one and it does not harm the eyes unlike what happens with incandescent bulbs. They use less power than most other types of light sources around the house.

What Gauge Wire should be used for 12V LED Lights?

You can use low-temperature and high-temperature wire for outdoor projects. The temperature of the gauge cable will depend on its durability and quality.

Again, if you are going to install it inside the building then choose a heat resistant one as this will prevent damages due to too much heat exposure.

Most 12V LED lights are sold per foot. It would be best to get enough wire so you can use it in various applications without the need to purchase more of it.

A good way to calculate the length needed is by going to your local hardware store and asking for a sample of the gauge wire required for your projects. You will then base your calculations on that sample.

Make sure the gauge of the wire fits your project needs such as size and temperature. You can opt for a 24 gauge wire for small lights while you can choose a 14-gauge wire for large projects. The thickness will depend on many factors including its intended use and desired appearance.

What To Look For When Buying Gauge Wire for 12V LED Lights?

This guide for Gauge Wire is meant to give you a starting point in understanding how different gauge wire impacts the light output of your LED Strip Lights.

The guide will help you understand which strips are the most efficient with both power and wiring costs, allowing you to maximize your initial investment. Following are some of the buying tips:

1. Gauge

A higher gauge wire will produce more lumens from your LEDs but at an increased cost and decreased flexibility whereas a lower gauge wire will be less luminous but it will be economical.

2. Power Source

Specifically, the light output of your LED lighting project depends upon the power source. The greater voltage generated by the power source will result in more luminous light and vice versa.

3. Amp Rating

When it comes to choosing wire size for LED lighting, the thing we need to choose is amp rating. With amp rating, we can work out how much current our wires are designed to carry safely before they get too hot or start melting/burning.

4. Wire Resistance

The resistance of a wire is the measure of how much it slows down the current. Resistance in any circuit must be accounted for by multiplying its value by the voltage supplied to that circuit and then dividing that product by the current flow through that circuit.

Final Verdict!

Based on the above review, it is concluded that Gauge Wire for 12V LED Lights is best suited for applications where power loss is not a critical issue.

It can be used for electrical wiring and as an electric cable that can carry a heavier current than soft copper wire.

Q. How to choose the right Gauge Wire for 12V LED Lights?

The too thick wire will cause power loss and too thin wire can’t carry enough current to enjoy the full brightness. Finding a good balance is critical in high-power LED light systems.

It’s important that you use the right gauge wire for 12V LED Light strings or have experienced installers do it for you.

Q. What is AWG and how does it work with gauges of wire?

AWG stands for American Wire Gauge, which is a standardized wire-gauge designation used in North America to define the diameter of solid and stranded conductors.

The AWG standard specifies different gauges for use with solid wires (single conductor) and stranded wires (multiple conductors). 

Q. What is the difference between stranded and solid-core gauge wire?

If the cross-section of a wire is circular, it’s called stranded. The electrical conductors in lamp cords are stranded.

On the other hand, if the cross-section of a wire is solid or flat with no holes to pass another wire through, then that wire is called solid core.

Q. When should I use higher gauge wires for 12V LED lights, such as 16AWG or 14AWG instead of 12AWG?

It all depends on the accessories that will be hooked up to the lights. You can use 12AWG wire with a 2A fuse, or you can also use 16AWG wire with a 2A fuse and get the same amount of current.

Q. What does the gauge number of the gauge wire correspond to?

Wire gauge is a standardized wire which is measured in gauge number. The higher the gauge number, the smaller the diameter of the wire is.
