CCT Selectable AC Controller

No, and that's their main advantage. These high voltage controllers are designed to work directly with AC 110V or 220V light strips. The controller itself manages the power regulation, so you wire it straight from your mains power. It's a much simpler setup for long runs compared to low-voltage systems which require bulky drivers.

Generally, yes, as long as the strip is a high-voltage AC CCT type and its power draw doesn't exceed the controller's maximum wattage. The key is the number of wires. CCT tunable white strips have three wires (a common live and two separate neutrals). If your strip has this setup and matches the controller's voltage (110V or 220V), it should be compatible.

You'll need a controller system that's designed for multiple inputs. Many of our models, like the Wiring Free Touch Panel kit, pair a wireless wall panel with the main receiver. The wall panel looks and feels like a regular switch but it's actually an RF remote. This lets you have a physical switch on the wall and a handheld remote on the coffee table, both controlling the same lights without running new signal wires.

It means you can adjust the color of the white light, anywhere from a warm, cozy yellow-white (like an incandescent bulb, around 2700K) to a cool, crisp blue-white (like daylight, around 6500K). These controllers work with tunable white light strips by blending two sets of LEDs on the strip to get the exact shade of white you want for the time of day or mood of the room.

They need some ventilation. These controllers handle mains voltage and will generate a bit of heat, so sealing them in an airtight box inside a wall is a bad idea. They should be installed somewhere they can get at least some airflow, like in an accessible part of a ceiling void, inside a cabinet, or a properly ventilated junction box. Never bury them directly in insulation.

The most common mistake is miswiring the 3-wire output. A high voltage CCT tunable white LED strip has a common live wire and two separate neutral wires—one for the warm LEDs and one for the cool LEDs. If you've mixed up the neutrals or only connected one, you'll only get one color. Double-check your connections against the controller's wiring diagram.

Yes, nearly all modern controllers have a power-off memory function. When you restore power, the lights will return to the last brightness and color temperature setting they had before the power was cut. This is a crucial feature, especially if you're using a standard wall switch for simple on/off control.

The ones that use the Tuya Smart Life platform are. Look for 'Tuya' or 'WiFi' in the product name, like our S3(WT) controller. Once you've set up the controller in the Tuya app, you can link your Tuya account to Amazon Alexa or Google Home. After that, you can use voice commands like 'Alexa, set the kitchen lights to warm white' or 'Hey Google, dim the ceiling lights to 50%.'
