2. Safety Information
- This product is designed for indoor use only (IP20 rated). Do not expose to moisture or outdoor elements.
- Ensure the power supply is disconnected before installation or maintenance.
- A DC 24V 120W power supply and an RGB LED controller are required and sold separately. Ensure all components are compatible and meet the specified voltage and wattage requirements.
- Do not connect the LED strip directly to AC power.
- Avoid bending the strip sharply or applying excessive force, which may damage the LEDs or circuit board.
- When cutting the strip, always cut at the designated cut marks.
- Do not touch the exposed PCB (Printed Circuit Board) at the end of the LED strip when connecting wires.

5. Setup and Installation
5.1 Components Required (Not Included)
- DC 24V 120W Power Supply
- RGB LED Controller (PWM, WIFI, or DMX compatible)
5.2 Installation Steps
- Prepare the Surface: Ensure the installation surface is clean, dry, and smooth for optimal adhesion.
- Measure and Cut: Measure the desired length for your installation. The LED strip can be cut every 2 inches (5 cm) at the designated cut marks. Always cut at these specific points to avoid damaging the circuit.

7. Maintenance
- Cleaning: Gently wipe the LED strip with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the strip is powered off and cool before cleaning.
- Adhesive Check: Periodically check the adhesive to ensure the strip remains securely attached. Reapply or reinforce if necessary.
- Lifespan: The LED strip has an average lifespan of 65,000 hours under normal operating conditions.
8. Troubleshooting
- Lights not turning on:
- Check if the power supply is properly connected and receiving power.
- Verify that the LED controller is correctly wired to both the power supply and the LED strip, ensuring correct polarity.
- Ensure the controller is turned on and set to an active mode.
- Inconsistent brightness or color:
- Ensure the power supply wattage is sufficient for the total length of the LED strip(s) connected.
- If using multiple strips, confirm that RGB amplifiers and additional power supplies are correctly installed as per the multi-roll wiring diagram.
- Check for loose connections between the strip, controller, and power supply.
- Strip detaching from surface:
- Ensure the surface was clean and dry before initial installation.
- Reinforce with additional adhesive clips or stronger adhesive tape if needed.
