A lighting system includes a plurality of fixtures, wherein each fixture includes a plurality of fluorescent lamps. A dimming ballast is operatively coupled to each fixture, each dimming ballast receives power from an outside source that is delivered to the fluorescent lamps within each corresponding fixture. A control module communicates with each dimming ballast, the control module receives a lighting level from an outside source, determines the most power efficient lighting solution and outputs a control signal to each dimming ballast related to the light output level of each lamp within each fixture.
