Light Emitting Plasma Outdoor Lighting Scaled Field Placement

This study evaluates the performance of a test installation of Light Emitting Plasma (LEP) lighting and a wireless lighting control system, as compared to incumbent High Pressure Sodium (HPS) lighting, in a high mast application at a study site in northern California. The study evaluates energy savings resulting from the installation of LEP fixtures in place of the existing HPS fixtures, as well as the potential savings available from the wireless control system installed with the LEP fixtures. In addition, the study assesses illuminance levels and the visual quality provided by the LEP fixtures.
