Claim 82:
83. The LED lighting device according to claim 76, wherein the at least one external control device comprises a selection switch connectable respectively to five 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 with a second resistor being connected in series with the second LED load, a third switching position electrically connected to both the first LED load and the second LED load, a fourth switching position electrically connected with both the first LED load and the second LED load with a first resistor being connected in series with the first LED load, and a fifth switching position electrically connected to only the second LED load, wherein the power loading circuitry comprises five power loading options including a first power loading option, a second power loading option, a third power loading option, a fourth power loading option and a fifth 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 with the first electric power being 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 with the first electric power delivered to the first LED load being greater than the second electric power delivered to the second LED load to generate the diffused light with a low-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 distributed to both the first LED load and the second LED load with the first electric power being equal to the second electric power to generate the diffused light with a medium diffused light color temperature; wherein when the selection switch is electrically connected to the fourth switching position, the fourth power loading option is activated with the DC power being distributed between the first LED load and the second LED load with the second electric power delivered to the second LED load being greater than the first electric power delivered to the first LED load to generate the diffused light with a high-medium diffused light color temperature, and when the selection switch is electrically connected to the fifth switching position, the fifth power loading option is activated with the DC power being delivered to only the second LED load with the second electric power being equal to the DC power to generate the diffused light with a high diffused light color temperature.
