Controllers for RGB, RGBW, CCT and single-colour LED strips

LED strip controllers make it possible to switch a lighting installation on and off, adjust its brightness and configure its operation. Depending on the strip type, they can also change the colour temperature, select colours and create dynamic effects or transitions.

At DomiLED you will find controllers for LED strip lights designed for single-colour, CCT, RGB, RGBW and RGB+CCT systems. Before selecting a model, check the operating voltage, number of channels and total connected power.

Which controller does each LED strip require?

• Single-colour controller: adjusts the brightness of a strip with one fixed colour, such as warm, neutral or cool white, red, green or blue.
• CCT controller: mixes two white channels to adjust the light from warm white to cool white.
• RGB controller: manages the red, green and blue channels to create different colours and lighting effects.
• RGBW controller: controls the three RGB channels and an independent white channel for both coloured effects and practical white illumination.
• RGB+CCT controller: manages RGB together with warm and cool white channels in compatible installations.

The controller must match the type of LED strip. An RGB controller cannot correctly manage an RGBW or CCT strip because the number of channels and electrical connections is different.

Voltage, current and maximum power

The controller must support the operating voltage of the LED strip, such as 12V or 24V DC. Never use a controller or strip with an incompatible voltage.

Check the maximum current per channel and the total supported power. Calculate the load by multiplying the strip’s consumption per metre by the installed length. The result must remain below the controller’s maximum capacity, with an appropriate safety margin.

If the installation exceeds the supported load, it may need to be divided between several controllers or expanded with a compatible signal amplifier. Overloading the device can cause malfunction, overheating or damage.

Remote, wall and smart control

Depending on the model, an LED strip can be managed through a remote control, wall panel, push button, mobile application or automation system. Radio-frequency controls do not normally require a direct line of sight between the remote and receiver, while infrared systems generally do.

Wi-Fi, Bluetooth and smart-system controllers may offer app control, schedules, scenes and additional functions. Before ordering, check the communication protocol and its compatibility with the remote, gateway or control platform.

Controllers for addressable LED strips

Addressable LED strips require a dedicated controller capable of sending data to the integrated circuit of each LED or LED group. They do not operate in the same way as conventional analogue RGB strips.

For these systems, the voltage, chip type, data signal and controller configuration must all be compatible. Incorrect connections may prevent operation or damage the electronic components.

How to connect an LED strip controller

In a conventional installation, the power supply is connected to the controller input and the LED strip to its output channels. Observe the polarity, identify each channel correctly and complete all wiring with the electrical supply disconnected.

Use cables with a suitable cross-section for the current and distance. Long runs may require additional power injection points to prevent voltage drop and visible differences in brightness or colour.
