1. A linear light-emitting diode (LED) lighting apparatus, comprising:
an array of light emitting diodes (LEDs) having a first length, wherein the array of LEDs comprises:
a first plurality of LEDs configured to produce a first light having a first color temperature, wherein the first plurality of LEDs aligns within a first linear shape;
a second plurality of LEDs configured to produce a second light having a second color temperature different from the first color temperature, wherein the second plurality of LEDs align within a second linear shape;
a driver circuit configured to output a plurality of currents;
a switch assembly configured to couple to the driver circuit, wherein the switch assembly comprises:
a first switch configured to cause the driver circuit to output one of the plurality of currents;
a second switch configured to cause the one of the plurality of currents to couple to the first plurality of LEDs, the second plurality of LEDs, or both; and
wherein the linear LED lighting apparatus is configured to electrically couple to an additional linear LED lighting apparatus having a second length different than the first length by a scale factor, wherein the additional linear LED lighting apparatus is configured to produce a third light having the first color temperature via a third plurality of LEDs or a fourth light having the second color temperature via a fourth plurality of LEDs.
