Abstract
A light emitting diode (LED) lighting fixture is provided. The lighting fixture includes a first LED engine and second LED engine. The first LED engine is configured to emit light corresponding to a first correlated color temperature. The second LED engine is configured to emit light corresponding to a second correlated color temperature that is different than the first correlated color temperature. When the first LED engine is hardwired to a power source, a light output of the lighting fixture corresponds to the first correlated color temperature. When the second LED engine is hardwired to the power source, the light output of the lighting fixture corresponds to the second correlated color temperature.
