Shielding radio frequency interference (RFI) using reflector optics is disclosed. A simplified non-sealed reflector is used in conjunction with a mounting system, resulting in desired amounts of visible and non-visible light using radio frequency driven luminaries and emitters without sacrificing output or coverage area. Configurations are disclosed such that achieved RF grounding is compliant with FCC regulations. Accordingly, the disclosed RFI shielding improves optical design options, increased output, and decreased manufacturing costs over traditional sealed enclosures.
