12v vs 24v LED Light Strips: A Simple Comparison

Many of our customers are eager to install LED Strip Lights in their homes, but they often find themselves stuck when deciding between 12V and 24V options. At LEDSave, we carry both voltage types, but which one should you opt for? Thankfully, the distinction is quite straightforward. In this post, we'll guide you through the key differences so you can make an informed decision tailored to your project.

Here's a side-by-side comparison of our two most popular LED strip options:

Spot the difference, and you'll notice that the distinctions are relatively minor. The main difference lies in the maximum run length: 24V strips can cover twice the distance of 12V strips before requiring additional power sources.

A Closer Look at 12V vs 24V LED Strip Lights

Before we dive deeper, let's quickly clarify what LED strip lights are. Essentially, these are flexible PCBs equipped with LEDs. Their versatility allows you to use them almost anywhere—under cabinets, behind furniture, or as decorative highlights. They're used for everything from task lighting to ambient illumination, thanks to their efficiency and brightness.

Understanding Voltage

Voltage, measured in volts (V), refers to the electrical potential difference between two points. For LED strips, the voltage determines the amount of power needed to operate the lights. The two common options are 12V and 24V.

Pros & Cons of 12V LED Strip Lights

Advantages of 12V Strips:

1. Easy Installation: Since 12V strips require shorter distances, they're simpler to set up.
2. High Versatility: Ideal for smaller, intricate projects like under-cabinet lighting or accent pieces. With cut intervals every 50mm, you can easily trim them to fit specific dimensions.
3. Wide Product Range: There’s a vast selection of 12V LED strips available, making it easier to find exactly what you need.

Disadvantages of 12V Strips:

1. Voltage Drop: A major downside of 12V strips is voltage drop over long distances. This results in dimmer lights at the far ends, limiting the effective length of a single power source.
2. Inefficiency for Long Runs: Due to voltage drop issues, 12V strips aren't as efficient for extensive installations. You may need multiple power supplies or segmented setups.

Pros & Cons of 24V LED Strip Lights

Advantages of 24V Strips:

1. Reduced Voltage Drop: 24V strips experience less voltage drop over the same distance compared to 12V strips. This ensures consistent brightness throughout longer runs.
2. Perfect for Long Runs: If you're planning a lengthy installation, 24V strips are usually the better choice. Our 24V strips can span up to 10 meters without losing brightness.
3. Increased Efficiency: Generally, 24V systems are more energy-efficient. Doubling the voltage halves the current required, resulting in lower energy consumption over time.

Disadvantages of 24V Strips:

1. Less Flexibility for Small Projects: While 24V strips excel in long runs, they may not be ideal for intricate or small-scale projects due to their larger cut intervals (100mm).
2. Limited Availability: Although the range is expanding, there are still fewer options available in 24V compared to 12V. This could restrict your choices based on your requirements.

Making the Right Choice for Your Project

Consider the Length of the Run

For projects involving long LED strip runs, 24V strips are usually the better option. The reduced voltage drop ensures consistent brightness across the entire length. Shorter runs or detailed work generally work well with 12V strips, which are easier to handle.

Think About the Power Supply

Your power supply is a critical component. For long runs, you may need a more robust power supply, and 24V systems offer more efficient power delivery due to lower current requirements (Power = Voltage x Current). Ensure your power supply matches the voltage of your LED strips and can handle the total wattage of your setup.

Flexibility and Cutting Needs

For projects requiring precision cuts into small sections, such as intricate accent lighting or detailed backlighting, 12V strips are typically superior. Their shorter cut intervals allow for more accurate trimming, ideal for custom shapes and sizes.

Energy Efficiency

If energy efficiency is a priority, consider the overall length and usage of the strips. Both 12V and 24V systems can be efficient, but 24V systems are often more efficient over longer distances, potentially reducing energy costs over time.

Final Thoughts

Both 12V and 24V LED strip lights have their own merits and cater to different project types. By evaluating factors such as run length, power supply needs, flexibility, and energy efficiency, you can select the best option for your project.
