What You'll Learn
Use a connector for easy attachment
Connecting LED strip lights can be done in a few different ways, but one of the quickest and easiest methods is to use a connector. This is a simple process, but it's important to take your time and be careful to ensure everything works properly.
First, you'll need to measure the space where you plan to place the lights. Use a measuring tape to determine the length of the area, then compare that to the length of your LED light strip. It's a good idea to measure twice for accuracy. Mark any differences in length, as you'll need to cut the strip to size.
Before cutting, make sure your LED strip light is not plugged in or turned on. Look closely at the strip for designated cut points, which are often marked by small scissors icons or dots. Cut the strip at these points to avoid damaging the components and ensure the lights work properly. If you're using RGB (colour-changing) strips, be aware that you'll need to cut the strip at a point that allows enough wires for the connector.
Once you've cut your strip to size, it's time to connect it. There are two main types of connectors: clip-on and fold-over. Choose a connector that matches your LED type and the wires you'll be using. If your LEDs are very close together, you won't be able to use a fold-over connector as it won't have enough space to close. Align the dots on the end of the light strip with the wires on the connector, then attach the strip to the connector.
If you're joining multiple strips together, you can use an LED light strip extension kit, which contains various connectors, or a solder-free interconnection cable. For strips that meet at a 90-degree angle, use a flexible connector.

Solder the wires for a stable connection
Soldering wires to LED strips can be challenging, but it creates a more stable connection and allows for a higher current flow than connectors. Here's a detailed guide on how to do it:
Prepare Your Workspace and Materials:
Before you begin, ensure your workspace is clean and free of debris. Gather all the necessary tools and materials, including wire cutters, wire strippers, a soldering iron, solder, and clamps or "helping hands" to hold the LED strip in place. You will also need the LED strip itself and the wires you wish to solder to it.
Strip and Expose the Wires:
Use the wire cutters to carefully strip away 2-3 mm of insulation from the end of the wires, exposing the bare copper underneath. This step is crucial, as the solder needs to make direct contact with the copper to create a strong connection.
Clean and Pre-Tin:
Clean the soldering iron tip, and pre-tin both the wires and the LED strip contacts. Pre-tinning involves applying a small amount of solder to the wire and the contact points, creating a better surface for the main soldering process. Heat the element so that the solder melts and wicks onto the surface. Be careful not to apply too much heat, as this can damage the wires or the strip.
Solder the Wires to the LED Strip:
Now, it's time to solder the wires to the LED strip. Line up the wires so that the colours match correctly according to the labels on the light strip. Apply a small amount of solder to each joint, connecting the wires to the LED strip. Work slowly and carefully, ensuring that each wire is correctly attached to the right contact point. Avoid overheating the wires, as this can ruin the LED lights.
Allow the Solder to Cool:
Once you've finished soldering, remove the heat and hold the wires in place until the solder cools and solidifies. Do not touch the strip during this cooling process to ensure the solder sets properly.
Test and Enjoy:
After the solder has cooled, you should have a strong and dependable connection. For extra strength, consider applying a small amount of hot-melt glue over the connections and covering them with heat shrink tubing. Finally, test your LED strip lights by plugging them into a power source and turning them on.
Remember, soldering LED strips can be tricky, and it may take a few attempts to perfect your technique. Always work with caution and follow safety guidelines when handling soldering equipment.

Prepare the power supply
To prepare the power supply for your LED strip lights, you'll need to gather the right tools and materials. The power supply, also known as a transformer or LED driver, is what powers your lights by converting high-voltage mains power into low-voltage DC power.
Firstly, decide where you want your lights to go. This will help you determine how much lighting is needed and how long your LED light strips should be. Measure the space with a measuring tape and compare it to the length of your LED light strip. It's recommended to purchase a light strip that's slightly longer than you need to avoid it being too short.
Next, check the power requirements of your LED strip lights. Typically, the specifications will indicate the required voltage (e.g. 12V or 24V) and wattage per meter. Ensure that your power supply matches these requirements to avoid damaging the lights.
Before making any connections, disconnect the power supply from the mains. Identify the input and output terminals on the power supply. The input terminals (blue for neutral, brown for live, and green and yellow for earth) connect to the mains power, while the output terminals (black for negative and red for positive) connect to the LED strip lights.
If you're using an LED light strip extension kit, carefully slide the cut end of one light strip into each side of a connector. Repeat this process until you've reached your desired length. If you're joining strip lights at a 90-degree angle, use a flexible connector.
Now, you can connect the power supply to the mains power and the LED strip lights. Strip the insulation from the ends of the cables and match the positive (+) and negative (-) terminals of the power supply to the corresponding terminals on the LED strip lights.
Once the electrical connections are made, turn the mains power back on and test your setup. If the lights don't turn on, double-check the polarity and ensure all connections are secure.

Cut at designated points
Cutting LED strip lights is easy, but it's important to cut them in the right place. LED strip lights are designed to be cut at specific intervals, typically marked by designated cutting points along the strip. These cutting points are usually indicated by dashed lines, small scissor icons, or dots printed on the strip. Before cutting, make sure the lights are unplugged and turned off.
To cut the LED strip, hold the lights still and use sharp scissors or a utility knife to cut along the dashed line or scissor icon. Cut carefully between the copper dots to avoid damaging the LEDs. If your strip lights are thicker, you may need to use wire cutters instead.
After cutting, you can connect the strip to another strip or a power source using a quick connector. Quick connectors are hassle-free ways of completing the electrical circuit. Line up the cut end of the light strip with the wires on the connector, ensuring the colours match correctly. Then, pull the small plastic bar of the connector back, peel the adhesive backing from the end of the strip to expose the copper terminals, and plug the strip into the connector. Finally, close the plastic bar again.
If you don't have a connector, you can also solder the wires to the strip, creating a more stable connection. To do this, scrape the plastic cover off the end of the LED strip above the copper dots. Then, heat up a soldering iron and hold the metal solder wire over the LED to melt the solder wire directly onto the copper dots. Be careful not to heat the wires for too long, or you might ruin the LED lights.

Secure the connection
Securing the connection of your LED strip lights is a straightforward process when you understand the components and follow a step-by-step guide.
Firstly, you need to cut the strip at the designated cut points, which are often marked by small scissors icons or dots. It is important to cut only at these points, as cutting too close to the LED lights will prevent them from working properly.
Once you have cut the strip to the desired length, you can connect the wires to the strip lights. If your LED strip lights did not come with connectors, you can either use a connector for easy attachment or solder the wires to the strip, which carries more current and creates a more stable connection.
If you are using a connector, choose one that matches your LED type. There are two main types of connectors: clip-on and fold-over. If you are using RGB (colour-changing) strips, make sure the connector has enough slots for all the wires. Line up the dots on the end of the light with the wires on the strip connector, and attach the light strip to the connector.
If you are soldering the wires, work slowly and carefully to ensure each wire is correctly attached to the right contact point. It only takes a small dot of solder to attach the wires securely to the strip, and you should avoid heating the wires for too long, or you might ruin the LED lights.
After you have made the electrical connections, test the lights to make sure they are working properly before mounting them in your desired location. Most LED strips come with a self-adhesive backing, but you may need additional mounting clips or brackets, or you may choose to mount them inside an aluminium profile rail, which can make the installation look more professional and protect the LEDs.
