The RGBW remote controller with ultra sensitive glass touch colour wheel is used to adjust the colour mixing fast and accurately. Each controller can control up to 6 zones separately or synchronously with multiple receivers in each zone. There are 10 built-in pattern changing programmes with pause function when played. A colour saving function is available enabling you to save a specific colour for 1 button selection, and 6 different favourite colours can be saved for each zone. The LED RGBW controller can create millions of colours due to the independent brightness adjustment of each R, G, B, W channels.
