Choosing the right LED strip for your specific needs can be a daunting task, especially when it comes to technical aspects such as voltage. In this article, we will examine the difference between 12V and 24V LED Strip and help you make the best choice for your requirements.

What is the difference between 12V and 24V LED Strip?

The main differences between 12V and 24V LED strips are the voltage, the length of the barrel, the brightness, the power consumption and the intersection points. The choice between 12V and 24V depends on the specific requirements of your project.


The voltage refers to the force that drives the current through the conductor. For LED strips, the voltage is either 12V or 24V. The voltage does not determine the brightness of the LEDs, but influences other factors such as the running distance and the number of intersections.

Run distance

Running distance refers to the maximum length of the LED strip, which can be operated with a single power source without a noticeable voltage drop. With 24V LED strips, the running distance is usually longer than with 12V LED strips, as they have a lower voltage drop.


The brightness of the LEDs is not determined by the voltage, but by the quality of the LEDs used and the current they receive. Both 12V and 24V LED strips can achieve the same brightness provided they are operated with the correct current.

Power consumption

24V LED strips usually consume less power than 12V LED strips. This is because they have less electrical resistance and therefore need less energy to produce the same luminous flux.


12V LED strips usually have smaller intersection points than 24V LED strips. This means they can be cut into shorter sections, making them more flexible and adaptable for projects with many tight curves or specific length requirements.

Fields of application

Both 12V and 24V LED strips can be used in a variety of applications. 12V LED strips are ideal for smaller projects and applications where flexibility and adaptability are required. 24V LED strips are better suited for larger projects and applications where long walking distances are required.

Power supply

Choosing the right power supply for your LED strip is crucial. 12V LED strips need a 12V power supply, while 24V LED strips need a 24V power supply. Using the wrong power supply can cause your LED strips to overheat and damage.

Electrical circuit design

The choice between 12V and 24V LED strips also affects the design of your electrical circuit. 24V LED strips can switch more LEDs in series, resulting in fewer parallel branches and easier circuit guidance.

Current flow

24V LED strips draw less current than 12V LED strips. This means that they are less likely to overload a circuit and generate less heat, resulting in a longer life of the LEDs.

24V LED strips usually provide better light efficiency than 12V LED strips. This is because they convert less energy into heat and convert more energy into light.


Whether you choose 12V or 24V LED strips depends on the specific requirements of your project, both have their pros and cons, and it is important to consider them before making a decision. If you need help choosing the right LED strip for your project, we are at your disposal.
