Which voltage should you use for LED strips?

12V LED Strip | Ideal for small installations

The 12V LED strip is one of the most commonly used options for home lighting projects. It operates on low voltage, which makes it a safer solution, especially in sensitive areas such as bathrooms or children's bedrooms. One of its main advantages is its flexibility. It can usually be cut every few centimeters, often between three and five, which allows for highly precise installations even on small surfaces or in tight spaces. This makes it a great choice for lighting under kitchen cabinets, inside display cases, along staircases, or around mirrors.

Like all low-voltage LED strips, it requires a driver to function properly since it cannot be plugged directly into a standard 230V wall outlet. It is also important to keep in mind that 12V LED strips may gradually lose brightness as the length increases. Beyond five meters, this drop in intensity can become noticeable unless the power supply is carefully adapted or multiple power input points are used.

Examples of use for 12V strip:

• Under-cabinet lighting for kitchens
• Bright atmosphere in a headboard
• Interior lighting for display cases or shelves

24V LED Strip | Better suited for longer installations

The 24V LED strip is often the preferred choice for professional projects or larger installations. Thanks to its higher voltage, the current flows more steadily, which helps reduce brightness loss over longer distances. Compared to the 12V version, it allows you to light larger surfaces with more consistent brightness throughout. It is especially effective for applications that require powerful LED strips or long, continuous lines of light, such as backlit ceilings, decorative walls, or retail lighting.

Although it is slightly less flexible than the 12V strip, cutting points are typically spaced every 10 centimeters, it is still relatively easy to install. Like the 12V version, it requires a specific power supply, but it tends to be more stable overall, generates less heat, and lasts longer under heavy use. For those looking for a professional and durable result, the 24V option is often an excellent choice.

Examples of use for 24V strip:

• Indirect lighting in a living room or showroom
• LED ceiling moldings 10 meters long
• Offices or commercial spaces

230V LED Strip | For Outdoor & long-length use

Unlike 12V and 24V strips, the 230V LED strip can be plugged directly into a power outlet without the need for a driver. This makes it especially convenient for installations where it would be difficult to hide or integrate a power supply. It is commonly used outdoors, for example on balconies, terraces, building facades, or for temporary events. It allows for easy installation of strips longer than 20 meters while maintaining consistent brightness along the entire length.

However, it is less flexible than other types of LED strips. It is more rigid, less bendable, and offers fewer cutting options. This makes it less suitable for indoor projects that require precision or a discreet finish. Additionally, even though it is often waterproof, it is important to check its protection rating (IP65 or higher) to ensure it can withstand moisture and dust, so that you can be sure that it is an LED strip for outdoor use.

Examples of use for 230V strip:

• Roof contours during the festive season
• Balcony or terrace bathed in light
• Outdoor signage

Practical tips for installing LED strips according to their voltage

Before installing an LED strip, it's essential to understand a few simple but important guidelines, which vary depending on the voltage you choose. The voltage you choose must match the power supply. Using a 12V power supply with a 24V strip or vice versa will damage the components and void warranties. Don’t worry, we’ll explain everything below based on the voltage you choose!

Installation for 12V LED strips

For 12V LED strips, installation is usually very straightforward, but special care should be taken when connecting the power supply. Make sure to use a driver that matches the total power required by the strip. These strips are well-suited for shorter lengths, but if you plan to connect multiple sections, it's best to power each segment in parallel rather than chaining them in series. This helps avoid brightness loss toward the end of the strip.

Installation for 24V LED strips

For 24V LED strips follow the same principle and also require a driver, but they offer the advantage of supporting longer lengths with more consistent brightness. Again, make sure the power supply provides enough wattage, and always double-check the polarity when connecting the wires. For longer installations, typically over 10 meters, it’s a good idea to use intermediate power sources or inject power from both ends to maintain uniform brightness.

Installation for 230V LED strips

For 230V LED strips, their main advantage is that they connect directly to a standard wall socket without an external power supply. This makes installation much simpler, especially outdoors or across long distances. However, these strips are more rigid and therefore less flexible when it comes to fitting them into tight spaces. It's essential to use the manufacturer’s recommended accessories, especially waterproof connectors if the installation is exposed to moisture.
