        LUMINAIRES
  A.1 Ballast Factors
  A.2 Luminaire Efficiency
  A.3 Luminaire Wattage

Provides Standardized tests to evaluate the energy efficiency of HID industrial luminaires. Provides a procedure for determining the luminaire efficacy ratings under laboratory test conditions, including visual tasks involved, luminaire placement, such performance characteristics as color and glare, lighting maintenance, on/off level control and a ballast\'s ability to regulate lamp wattage. When rating a fixture in accordance with EPAct 1992, use this Standard. For other purposes, see NEMA LE 6, a newer Standard for luminaire efficacy that supersedes the LE 5 series.
