Abstract
In an embodiment, a solid-state lighting circuit is included herein having a first plurality of emitters configured to output light of a first color and a second plurality of emitters configured to output light of a second color. The circuit further includes a current limiting circuit and at least one biasing resistor operably connected to the first plurality of emitters and the current limiting circuit. Current is biased toward the first plurality of emitters until a preselected current limit is reached for the first plurality of emitters, such that the first plurality of emitters outputs the light of the first color. When current is provided by the constant current power supply that is at or above the preselected current limit, current passes through the second plurality of emitters such that the second plurality of emitters outputs the light of the second color. Other embodiments are also included herein.
