1. An improved lighting apparatus comprising:

  • a plurality of variable intensity lighting pods, each lighting pod focused on a work field and disposed along a radius extending from the work field;

    a proximity sensor within each lighting pod for detecting objects interposed between the light pod and the work field; and

    a power control circuit coupled to each lighting pod and each proximity sensor for varying the light intensity of particular variable intensity lighting pods in response to objects interposed between selected lighting pods and the work field by decreasing the light intensity of each lighting pod having an object interposed between that lighting pod and the work field such that shadows within the work field are minimized.
