What Is The Best Cable For 12v Lighting?


When the idea for installing LED lighting, most people would think it’s a job for top professionals. That is not entirely true; LEDs use low voltage currents through a transformer. However, if you’re installing 12-volt LED lights, keep a few things in mind while choosing a 12v cable for led lighting. This article will explain how to choose a 12v lighting cable and recommend the best cable for 12v lighting. 

Our top choice for the best cable for 12v lighting is the Aotorua gauge red-black cable. It has a high-quality PVC conductor, excellent conductivity, mechanical strength, anti-aging, acid, and alkali resistance. It can also be used in a broad range of applications from 12V to 330V DC; all single color LED strip lights and low voltage cables, and low-loss home or automobile radio installations.

When connecting landscape lights using 12v wires, it is important to know the difference between these cables. The two types of cable are stranded wire and solid wire. This will help you determine which cable you need for your wiring. So, what is the difference between stranded vs solid wire?

What is stranded wire, and how does it work?

Stranded wires, a thin, come in bundles that are insulated and compressed without conductive materials. It is easy to use a stranded wire because of the flexibility to bend and fit into tight spaces. When comparing solid wire, stranded wires are more flexible and often used indoors because they don’t sever or split.

What is Solid Wire, and how does it work?

Solid wires are thicker than stranded wires, and they are also heavier or bulky. The solid wire use or handles more current than stranded cable and is mostly used outdoors because it can withstand different weather and are durable.

Is it better to use stranded or solid wire?

 Solid wire and stranded wires are the two most common types of wire. A plastic insulating jacket surrounds a single solid conductor in the solid wire, generally copper. Rather than having many conductors in a single bundle, stranded wires have an insulating jacket covering the whole bundle.

Even though the stranded wire is bendable, it may not be that easy to manipulate. It needs some soldering to make it strong enough to be inserted into a cable. However, the wire with a solid wire is more malleable and easier to join. Therefore, it is preferable to utilize the solid core wire for your LED lights since it is more convenient.

Performance is the main difference between stranded and solid cable. Stranded cables display 20 to 50% greater attenuation than solid copper conductors due to insertion loss (20 percent for 24 AWG and 50 percent for 26 AWG). In addition, stranded conductors have a greater DC resistance than solid cables because their cross-section is not entirely copper. 

Solid cables are better electrical conductors with more consistent electrical properties. In addition, because they have less surface area than stranded conductors, they are considered more robust and less prone to vibration and corrosion.

 How to Determine the Correct Wire Gauge

  1. Determine how many feet of wire you’ll need to connect an LED strip as the first step in this procedure.
  2. Determine the maximum possible current across the wire. 
  3. Then, add the entire length of LED strips connected to the power source and multiply this by the watts per foot to get the total wattage. 
  4. An LED light, for example, uses roughly 4.4 watts per foot of light. So, over a distance of 16 feet, multiplying 4.4 by 16 yields a power output of 70.4 watts.
  5. The total amps, or current, is obtained by multiplying the total wattage by 12. Divided by 12, this amounts to 5.87 amps, or 70.4% of the available wattage.
  6. To determine the proper wire gauge, please see the chart below. 
  7. An amp is located at the junction of two feet. When using 50 feet of cable and five amps, the wire gauge should be 10. 
  8. Remember that the wire itself pulls current, so if you are using a longer wire, be sure to pick a thick one. 
  9. Thicker wire is indicated by a lower digit in the numbering system.

Color-Coded Wire

If you’re using colored wires or cables, you’ll want to consider the color of their insulation as well. The color of the wire encapsulation is frequently a good indicator of what sort of wire is within.

  • Insulation in black or red implies a live or hot wire is present.
  • A cable or wire with a white or brown cover implies that it is a neutral wire or cable.
  • There is a ground wire inside if the cover is yellow or yellow-green.

It’s important to note that electricity can go through a neutral wire, so use caution while working with them. Also, before beginning any installation, turn off your circuit breaker or light switch.

Most individuals would recommend a solid-core 18-gauge wire, but if you want your wires to fit into most holders or terminals, you’ll have to choose between this 18-gauge wire and a much smaller cable, although the price difference is tiny. This cable size can handle far more than the typical system.

Wiring connections might be useful to install many 12v LED lights with dimming capabilities. Still, with 12V DC Connectors, you may make any low-voltage DC wire connections with simplicity and safety. Both positive and negative wires can be connected using these connectors. You may also use them for fishing boats, mobile homes, RVs, buses, automotive systems, solar systems, and wind systems, among other applications. With these connections, you may end tangled wiring once and for all.
