An LED lighting device includes a first luminescent device, a second luminescent device, a first current controller and a second current controller. The first current controller is coupled in parallel with the first luminescent device and configured to operate according to a first current setting, a switch-on voltage and a switch-off voltage. The second current controller is coupled in series to the second luminescent device and configured to operate according to a second current setting. The first current setting, the second current setting, the switch-on voltage and the switch-off voltage are adjusted by setting the mode selection pins of the first and second current controllers.
