ANSI C82.5

Description / Abstract: This standard describes the essential features and operating characteristics of reference ballasts for highintensity discharge and low-pressure sodium lamps operating on 60 Hz sinusoidal ballast systems. The items specified are those necessary to ensure accurate and reproducible results when lamps or ballasts are being tested. The specific values of rated input voltage and impedance for each lamp type are listed in the appropriate American National Standards for high-intensity discharge and low-pressure sodium lamps.
