A full-spectrum decorative string light has a light emitting diode (LED) light string and a control circuit. The LED light string includes multiple light units. Each one of the light units has a first LED and a second LED. The first LED is electrically connected to the second LED in parallel by inverse direction. Each one of the first LED and the second LED is selected from the group consisting of a yellow LED and a white LED. The first LED and the second LED have different colors. The control circuit is electrically connected to the LED light string to activate the LED light string by pulse width modulation (PWM) control signals. The duty cycles of the PWM control signals are changeable.
