Abstract: Embodiments include a lighting device that includes a first illumination source comprising a light-emitting diode (LED) of a first color that generates a first light output with a first melanopic ratio of greater than 0.8, and a second illumination source comprising an LED of a second color that generates a second light output with a second melanopic ratio that is less than the first melanopic ratio. The lighting device also includes a light distribution unit for directing and distributing illumination generated by the first and second illumination sources, where at least one of the first illumination source and the second illumination source is affixed to the light distribution unit, and where the first and second illumination sources are oriented relative to one another such that their respective light outputs are directed in different directions.
