Claim 81:
82. The LED lighting device according to claim 76, wherein the at least one external control device comprises a selection switch connectable respectively to three switching positions configured in the power loading circuitry including a first switching position electrically connected to only the first LED load, a second switching position electrically connected to both the first LED load and the second LED load, and a third switching position electrically connected to only the second LED load; wherein the power loading circuitry comprises three power loading options including a first power loading option, a second power loading option and a third power loading option; wherein when the selection switch is electrically connected to the first switching position, the first power loading option is activated with the DC power being delivered only to the first LED load, namely the first electric power is equal to the DC power, to generate the diffused light with a low diffused light color temperature; wherein when the selection switch is electrically connected to the second switching position, the second power loading option is activated with the DC power being delivered to both the first LED load and the second LED load to generate the diffused light with a medium diffused light color temperature; wherein when the selection switch is electrically connected to the third switching position, the third power loading option is activated with the DC power being delivered only to the second LED load, namely the second electric power is equal to the DC power, to generate the diffused light with a high diffused light color temperature.
