1. Use Corner Connectors: L-shaped or angled connectors are specifically designed to join two strips seamlessly at 90-degree angles. They not only make the installation easier but also maintain the electrical connections and alignment.
2. Install Aluminum Channels: These channels provide a rigid and protective frame for the LED strips, making it easier to achieve clean, even bends. The diffusers included with the channels can also help distribute light more evenly.
3. Plan the Layout: Before cutting or attaching the strips, map out the path, especially at corners. Measure and test fit the sections to minimize errors.

By using the right tools and techniques, you can overcome the challenges of corner installations, ensuring a durable and visually appealing LED lighting setup.

Beginner’s Guide: Preparing for Installation

Before applying or reapplying LED strip lights, evaluate your space:

• Identify where you want to place the LED strips.
• Measure the length required, accounting for corners and turns.
• Plan the layout to ensure proper placement and even lighting.

7 Easy Steps For Installing LED Strip Lights Around Corners

Step 1: Measuring and Planning Your Layout

• Use a Measuring Tape: Begin by measuring the total length of the area where the LED strips will be installed. Be precise to avoid wastage or shortage.
• Mark the Layout: With a pencil or marker, indicate the placement of the strips along the surface. Pay special attention to corners and ensure that the markings align with the direction of the lighting.
• Plan Corner Placement: For corners, decide whether you’ll use corner connectors, fold the strips carefully, or utilize corner channels. This step ensures you have the right tools and components ready.

Step 2: Clean and Dry the Surface

• Thorough Cleaning: Use a lint-free cloth soaked in isopropyl alcohol to thoroughly clean the surface. This removes oils, dust, and dirt that can interfere with adhesion.
• Inspect for Residue: Check the surface for any remaining residue or moisture. Repeat the cleaning process if needed to achieve a spotless finish.
• Ensure Dryness: Allow the surface to air dry completely or use a dry microfiber cloth to speed up the process. A dry surface is critical for a strong adhesive bond.

Step 3: Cutting LED Strips to Length

• Identify Cut Marks: Look for the designated cut marks on your LED strip. These are typically indicated by small scissor icons and ensure that the electrical circuit remains intact.
• Use Proper Tools: Use sharp scissors or a utility knife to make clean, precise cuts at the marked points. Avoid cutting outside these marks to prevent damage to the strip.
• Prepare for Connections: If the strip needs to connect to another section or a corner connector, expose the contacts carefully and ensure they are intact.

Step 4: Mount the Corner LED Channel

• Choose the Right Channels: Select corner channels that fit the width of your LED strip and match your installation style. These channels provide structural support and a polished look.
• Secure the Channels: Attach the channels to the surface using screws, adhesive, or mounting clips. Ensure they are aligned properly to guide the LED strips smoothly.
• Check for Stability: Once mounted, press the channels gently to confirm they are firmly secured and ready for the LED strips.

Step 5: Applying LED Strips with Corner Techniques

• Utilize Corner Connectors: For sharp 90-degree turns, use corner connectors designed for your LED strip type. These connectors bridge the electrical connection while allowing the strip to turn seamlessly.
• Avoid Over-bending: If you’re folding the LED strip around a corner, ensure the bend radius does not damage the strip’s circuitry. A gentle curve is preferable over a sharp fold.
• Double-check Alignment: Align the strip carefully with the markings you made earlier, ensuring it follows the intended path through the corners.

Step 6: Attach the LED Strips Inside the Corner Channel

• Peel and Stick: Remove the adhesive backing from the LED strip and press it firmly into the channel. Start from one end and work your way through to avoid bubbles or misalignment.
• Press Firmly: Use consistent pressure along the length of the strip to ensure it adheres well inside the channel.
• Trim Excess Material: If the strip extends beyond the channel, trim it at the nearest cut mark.

Step 7: Connect to the Power Supply and Test
