1. A solid state lighting circuit, comprising:

  • a plurality of emitters operably connected to a power supply, the plurality of emitters comprising at least two emitters with different color output than one another, the two emitters comprising a first emitter having a first color output and a second emitter having a second color output; and

    a switched circuit configured to bypass one or more of the emitters;

    wherein a controlling signal for the switched circuit to bypass one or more of the emitters is derived from the voltage of the power supply, wherein when the voltage is at a first voltage the emitters with the second color output are bypassed and when voltage is at a second voltage that is higher than the first voltage the emitters with the second color output are not bypassed.
