4-wire LED strips offer versatility and control options due to their separate wires for power, ground, red, and green channels. Understanding the wiring diagrams is crucial for successful installation and operation.

When wiring 4-wire LED strips, the power and ground wires should be connected to an appropriate power supply, while the red and green wires connect to a controller for color adjustment. The choice of power supply depends on the strip’s power requirements and length.

Strip Length and Power Requirements

The length of the LED strip determines the power supply requirements. Longer strips require higher power supplies to ensure adequate voltage and current throughout the strip. Here are some general guidelines:

  • For strips up to 5 meters, a 12V 5A power supply is sufficient.
  • For strips between 5 and 10 meters, a 12V 10A power supply is recommended.
  • For strips exceeding 10 meters, a 12V 15A or higher power supply is necessary.

Choosing the Right Power Supply

Selecting the correct power supply for 4-wire LED strips is crucial to ensure their proper functioning and longevity. Several factors must be considered when making this choice:

Power Consumption

  • Determine the total wattage of the LED strip by multiplying its length by its power consumption per unit length (typically specified in watts per meter).
  • Add an additional 10-20% to account for power loss and voltage drop.

Voltage Requirements

  • The power supply’s output voltage should match the voltage rating of the LED strip.
  • Using a power supply with a higher voltage can damage the LED strip, while using a lower voltage may result in insufficient brightness.

Current Capacity

  • The power supply must be able to provide sufficient current to drive the LED strip.
  • Calculate the required current by dividing the total wattage by the power supply’s output voltage.


  • Consider the power supply’s efficiency, which indicates how much power is converted into useful output.
  • A higher efficiency means less power is wasted as heat, resulting in lower operating costs.

Protection Features

  • Look for power supplies with built-in protection features such as overvoltage, overcurrent, and short-circuit protection.
  • These features help prevent damage to the power supply and the LED strip.

Selecting and Using Controllers

Controllers play a crucial role in managing the functionality and effects of 4-wire LED strips. They allow for seamless control over color, brightness, and various lighting modes, enhancing the versatility and aesthetic appeal of LED lighting projects.

There are different types of controllers available, each designed to cater to specific requirements. Understanding their features and functions is essential for selecting the most suitable controller for your project.

Connecting multiple LED strips in series involves connecting the positive terminal of one strip to the negative terminal of the next, and so on. This method allows you to extend the length of your LED lighting installation without increasing the voltage or amperage requirements.


  • Extends the length of the LED installation
  • Maintains the same voltage and amperage requirements


  • If one LED strip fails, the entire series will be affected
  • The maximum length of the series is limited by the voltage drop

Connecting Multiple Strips in Parallel

Connecting multiple LED strips in parallel involves connecting the positive terminals of all the strips together, and the negative terminals of all the strips together. This method allows you to increase the brightness of your LED installation without increasing the voltage or amperage requirements.


  • Increases the brightness of the LED installation
  • Maintains the same voltage and amperage requirements


  • Requires more wiring
  • If one LED strip fails, the other strips will not be affected

Troubleshooting Common Issues

Wiring 4-wire LED strips can sometimes present challenges. Identifying and resolving common problems is crucial for successful implementation.

One common issue is incorrect wiring. Ensure proper connections between the strip, controller, and power supply, adhering to the designated polarity. Loose connections can lead to flickering or complete failure.

Power Supply Issues

Inadequate power supply can cause dimness or flickering. Select a power supply with sufficient wattage to handle the connected LED strip length. Overloading the power supply can lead to overheating and potential damage.

Controller Malfunctions

Faulty controllers can disrupt LED strip functionality. Check for proper connections between the controller and the LED strip and power supply. Replace the controller if necessary.
