Dual White Color CT LED Dimmers
39 productsA Dual-White CCT LED Dimmer Controller does more than just dim your lights; it controls their mood. While a basic single-color dimmer only adjusts brightness from 0-100%, a CCT color temperature controller gives you command over the shade of white light itself. It works by independently managing the two sets of LEDs on a 3-wire tunable white LED strip — one warm white and one cool white. By blending these two channels, you can dial in any color temperature from a cozy, incandescent-like 2700K to a crisp, neutral 4000K or a bright, energizing 6500K daylight.
This level of led light color temperature control is essential for spaces that serve multiple purposes. You can set a warm, relaxing tone for the evening and switch to a cool, focused light for daytime work, all with the same lighting fixture. Getting the right control interface is the first step. SuperLightingLED™ offers a huge range of CCT dimmers to suit every project's different needs, from simple remote control to fully integrated smart home systems with voice commands.

How Do You Choose a CCT LED Dimmer?
The best led dimmers for your project depend entirely on how you want to interact with your CCT lighting. Do you need a simple handheld remote, a permanent wall switch, or control from your phone? We build controllers for all three scenarios.
RF Wireless Remotes & Panels
This is the most straightforward method. An RF (Radio Frequency) system gives you a dedicated handheld remote or a wireless wall panel that you can mount anywhere without running new wires. They are simple to pair and offer reliable control from up to 100 feet away.
WiFi & Voice Control Smart Dimmers
For smart home integration, our WiFi CCT controllers are the answer. These units connect directly to your home's WiFi network, letting you control your CCT lighting through an app like Tuya or Smart Life. This unlocks advanced features like scheduling, setting scenes, and, most importantly, voice control with Amazon Alexa and Google Home.
Hardwired Wall Controls
For a permanent and traditional feel, a hardwired CCT wall controller is the ideal choice. We have options ranging from sleek glass touch panels to classic rotary knob dimmers. These are perfect for new construction or renovations, providing a robust, in-wall solution that won't get lost like a remote.

How to Wire a CCT Controller
Wiring for color temperature led control is straightforward. Tunable white LED strips typically have three wires or connection points: a common positive (V+) and two separate negatives, one for the Warm White channel (WW) and one for the Cool White channel (CW). The CCT controller is installed between your power supply and the LED strip.
The wiring sequence is: Power Supply -> CCT Controller -> CCT LED Strip
For runs longer than a single reel (16.4ft / 5m), voltage drop becomes a factor. This can cause a visible shift in color temperature and a loss of brightness at the far end of the strip. The solution is to use a LED power signal amplifier. You'll run power from your main supply to the amplifier, which then provides a fresh power injection for the next section of strip lights, ensuring consistent color and brightness. For a more detailed walkthrough, read our guide on how to wire tunable white LED strips.
How to Size Your Controller and Power Supply Correctly
Mismatched components are the most common cause of failure in an LED system. To ensure safety and performance, your controller and power supply must be rated to handle the load of your LED strips. Follow these steps:
- 1. Match the Voltage: This is non-negotiable. If you're using a 24V CCT strip, you must use a 24V controller and a 24V power supply, like one from our MeanWell UL-listed indoor supply range. Using the wrong voltage will destroy the strip, the controller, or both.
- 2. Calculate the Total Amperage: Look at the strip's spec sheet for its power draw in watts per meter (or foot). Multiply this value by the total length of your run. This gives you the total wattage. Now, divide the total wattage by your system's voltage (e.g., 24V) to find the total amps.
- 3. Add a 20% Safety Margin: Never run a power supply or controller at 100% of its rated capacity. It generates excess heat and drastically shortens its life. Always select components rated for at least 20% higher than your calculated amperage. For example, if your strip system draws 8 amps, you should use a controller and power supply rated for at least 9.6 amps (a 10A model would be perfect).
Frequently Asked Questions About Dual White CCT LED Dimmers
Got questions about setting up your tunable white lighting? I've answered thousands of them over the years. Here are the most common ones that come up right before an install.
It lets you control the shade of white light. A tunable white (or CCT) LED strip has two sets of LEDs on it: one warm white (like a candle) and one cool white (like daylight). The CCT dimmer works by blending the brightness of these two channels. You can dial in anything from a cozy 2700K warm white all the way up to a crisp 6500K cool white, and every step in between. It gives you total control over the mood of the room.
They use something called Pulse Width Modulation, or PWM. Instead of lowering the voltage, the controller turns the LEDs on and off hundreds or thousands of times per second. To make the light dimmer, it just keeps the LEDs off for a larger fraction of each pulse. Your eyes can't see the flicker, you just perceive a smooth dimming. For CCT, it does this for two channels at once, changing the ratio of warm and cool pulses to blend the final color temperature. That's it.
A full tunable white LED strip control system has four key parts. First, the tunable white LED strip itself. Second, one of these CCT controllers to act as the brain. Third, a way to talk to the controller, like an RF remote, a wall panel, or a smartphone app. And finally, you need a DC power supply with the correct voltage (usually 12V or 24V) and enough wattage to power the whole strip run.
This is a common wiring mistake, so get this one right. The controller always goes *after* the power supply but *before* the LED strip. The order is: Wall Outlet -> Power Supply (converts AC to low-voltage DC) -> CCT Controller -> LED Strip. Never wire a low-voltage DC controller directly to high-voltage AC power. It will be destroyed instantly.
They're just different ways to send the signal. RF (Radio Frequency) uses a dedicated physical remote. It's simple, reliable, and doesn't need an internet connection. WiFi connects the controller to your home network, letting you use a phone app or voice assistants like Alexa and Google. Bluetooth connects your phone directly to the controller, which is great for simple setups where you don't want to deal with network passwords. Many of our smart controllers offer a few options in one unit.
This is almost always a wiring problem at the controller's output terminals. A CCT strip has three wires: one for warm white (WW), one for cool white (CW), and a common positive (+). You've likely got the WW and CW wires swapped, or one of them has come loose and isn't making a good connection. Double-check that all three wires are seated securely in the correct terminals. We have a guide on wiring CCT strips that shows it clearly.
It's a simple calculation. Find the wattage per meter (or foot) on your LED strip's spec sheet. Multiply that by the total length of your strip in meters. Then, divide that total wattage by your voltage (12 or 24). The result is the minimum amps your controller needs to handle. Always pick a controller and power supply rated for at least 10-20% *more* than your calculated minimum. An undersized controller will overheat and fail early.
You're seeing the PWM frequency. Standard controllers often use a low PWM frequency (a few hundred hertz) which is invisible to the eye but can be caught by a camera's shutter, creating that flicker or banding effect on video. For any application where you might be filming, you need a high-frequency or 'flicker-free' controller. We stock models like the LM-CH21 series that use a 20KHz PWM frequency, which is far too fast for any camera to pick up.
