Embodiments of the present invention are directed to systems for powering and controlling lighting fixtures in office buildings, homes, industrial facilities, and similar structures using low-voltage direct-current ('DC') electricity. Some embodiments of the present invention are directed to systems for distributing DC power from a lighting controller to various LED luminaires. Embodiments include (a) a power source configured to provide electricity at approximately 48 volts DC; (b) an LED lighting fixture that includes a cool LED luminaire tuned toward the blue end of the visible light spectrum and a warm LED luminaire tuned toward the red end of the visible light spectrum; (c) a variable input control device for setting the color/temperature of the light emitted by the LED lighting fixture; and (d) a lighting controller comprising a watt meter, a capacitor bank, a cool LED controller, a warm LED controller, an input controller, a lighting computer; and (e) a site computer that communicates with the lighting controller via a building network to provide certain operational controls over the LED lighting fixture.
