A lighting apparatus includes a first lighting module, a second lighting module, a rectifier, and a controller. The rectifier is used to rectify the AC power into an input power. The controller is coupled to the rectifier, the first lighting module, and the second lighting module for receiving the input power. When the input power is less than a reference value, the controller controls the first lighting module, the second lighting module, and the rectifier to form a first connection state. When the input power is greater than the reference value, the controller controls the first lighting module, the second lighting module, and the rectifier to form a second connection state. Also, a controlling method of the lighting apparatus is disclosed.
