LED Chromatherapy includes an LED light and an easy to use on/off push control. The LED light cycles through various colors and illuminates the entire water for a beautiful and soothing experience. Color has often been used in the past as treatment for illnesses. Since 1876, people used light waves to rid the mind and body of ailments and this is what is referred to as Chromatherapy. It is believed that each color has a different healing property. The included push control allows you to control the LED light, you can choose to have it cycle through a spectrum of colors or you can manually cycle it to your favorite color and have it hold there.
