LED strip lighting is a popular and versatile way to bring light into homes, workspaces and public environments. But for lighting to work reliably and safely, one thing is particularly important: the choice of LED strip cable. Choosing the right cable directly affects how well the lights work, how easy they are to install and what the end result looks like. In this article, we'll go through what type of cable is suitable for different types of LED strip lights, how cable colour and width affect installation, and practical tips to consider. We offer expert help with the whole process - from design to cables, lights, control and installation.
1. Single-colour LED strip - a two-core cable will do
The monochrome LED strip is a simple and effective solution for indirect lighting, for example. In this case, the choice of cable for the LED strip is easy: a two-core cable is sufficient. One wire leads to the plus pole and the other to the minus pole. The quality of the cable is still important - a poor quality cable can cause voltage drops or even overheating. The colour of the cable should be chosen according to the environment: black blends in with a dark background, white with a light surface. The two-core cable is easy to solder directly to the LED strip or to connect with lever connectors. We offer metric cable as well as ready-made cable sets that fit directly to the strip and power supply. With the right choice of cable, installation is quick and the lighting works perfectly.
2. CCT-led strip - three-core cable for colour temperature control
The CCT-led strip needs a three-conductor cable. This allows two different shades of white - warm and cool - to be controlled. The third wire acts as a common plus button. Selecting the cable for the CCT-led strip requires precision, as incorrect wiring can prevent the control function from working. We recommend using clearly marked cables where the colours of the wires are easily distinguishable. In practice, however, there may be differences between product batches, so it is a good idea to check and test the corresponding starting points of the wires and the LED strip before assembling and installing the unit.
Piston is recommended, but lever connectors can facilitate installation, especially in tight spaces. The thickness of the cable also affects the current flow - too thin a cable can cause light to be dimmed over long distances. LedStore will help you choose the right cable length and cross-sectional area for the power of the strip. When properly selected and installed, the CCT strip provides a versatile and pleasant lighting experience. Ready-made cable harnesses with splitters are also available. Led CCT strips do not have pre-fitted connectors, so the Led strip is connected to the wire by soldering.
3. RGB+W led strip - five-core cable for colours and white
The RGB+W-led strip combines colour lights and a separate white LED, so it needs a five-core cable. Each colour (R, G, B) and white has its own conductor, and a common plus wire is also required. Choosing the cable for the RGB+W LED strip requires care, as the number of wires adds to the challenge of installation. Four-conductor and five-conductor cables are easily confused; remember that RGB without white can be done with four conductors, but if white is included, there should be five.
The width of the cable is larger than for simpler cables, so it is a good idea to allow enough space for installation. Plunging ensures the best contact, but lever connectors also work in short pulls. Our range includes cables specifically designed for RGB+W strips, which fit directly into controllers and power supplies. When the cable is correctly selected, the RGB+W strip will work correctly, providing both mood lighting and practical white light at different brightness levels.
4. RGB+CCT-led strip - six-conductor cable requires space and precision
The RGB+CCT led strip is the most versatile option, and requires a six-conductor cable to control it. This allows for both colour and adjustable white control. The choice of cable for the RGB+CCT-led strip is particularly important because the cable is wide and requires space for installation. Spooling is almost essential to ensure that all the wires are properly attached to the strip. Lever connectors can work for short pulls, but long-term durability requires soldering.
The cable width can be up to 10 mm, so the dimensions of the installation profile should be checked beforehand. LedStore offers cables specifically designed for RGB+CCT strips and compatible with controllers and power supplies. With the right cable, even long runs of 20-30 meters to the transformer are possible without any worries.
5. Cable colour and width - finish the installation neatly
The colour and width of the cable affect both the appearance and practicality of the installation. Black cable blends in with dark surroundings, such as behind cabinetry or a black profile. White cable is suitable for light-coloured surfaces and exposed installations. Choosing the cable for your Led strip is not just a technical decision - it also affects the visual outcome. Wider cables, such as six-conductor, require more space and careful routing.
We can help you choose the right cable width and offer customised solutions if required. For installation, it is advisable to use cable glands to protect the cable and give a professional finish, especially for single-insulated flat cables (RGB+W and RGB+CCT). The cable's bendability also affects how easy it is to install the cable in tight spaces. In principle, low-current cables are very flexible. When the cable is selected correctly, the installation is faster and the lighting works reliably.
Summary - The choice of cable for the Led strip plays a major role in the success of the installation
Choosing the cable for your Led strip is a critical part of a successful lighting project. The right cable will ensure that the lights work as designed, the installation is safe and the end result is neat. The number, colour and width of the cable conductors should be matched to the type of strip and the installation environment. Coiled or lever connectors finish the joints, and a quality cable will last for decades of use.
LedStore offers expert assistance throughout the entire process - from design to cables, lights, control and installation. With the right cable, the LED strip works reliably and the lighting project is a success from start to finish.
