6. Setup and Installation
This LED strip requires a 12V DC power supply and an RGB LED controller (both sold separately) for full functionality.
- Prepare the Surface: Ensure the installation surface is clean, dry, and flat. Dust, grease, or moisture can reduce the effectiveness of the adhesive tape.
- Measure and Cut (if necessary): Measure the desired length for your installation. The LED strip can be cut at designated cutting points, typically marked every 5cm. Use sharp scissors to ensure a clean cut. Do not cut at any other point.

- Connect to Controller: Connect the 4-pin connector of the LED strip to the corresponding output port on your RGB LED controller. Ensure the pins are aligned correctly (typically marked R, G, B, +12V).
- Connect Controller to Power Supply: Connect your RGB LED controller to a compatible 12V DC power supply. Ensure the power supply's wattage meets or exceeds the total wattage required by the LED strip (5 meters * 18W/M = 90W maximum).
- Test Functionality: Before final adhesion, temporarily power on the system to ensure the strip lights up and responds to the controller as expected.
- Adhere the Strip: Carefully peel off the backing from the double-sided adhesive tape on the back of the LED strip. Press the strip firmly onto the prepared surface, working in sections to avoid bubbles or misalignment.
