Claim 34:
35. The method of configuring an LED lighting device with a tunable diffused light color temperature according to claim 34, wherein when each of the first LED load and the second LED load is configured with a plurality of LEDs electrically connected in series, or sets of in parallel connected LEDs electrically connected in series, a working voltage imposed on each of the first LED load and the second LED load is confined in a domain between a minimum voltage equal to the sum of the threshold voltages of all LEDs electrically connected in series or sets of in parallel connected LEDs electrically connected in series and a maximum voltage equal to the sum of the maximum operating voltages of all LEDs electrically connected in series or sets of in parallel connected LEDs electrically connected in series.
