ANSI C78.42
New product
ANSI C78.42 9th Edition, January 1, 2009 Electric Lamps — High-Pressure Sodium Lamps
More info
Description / Abstract:
This standard sets forth the physical and electrical requirements for HPS lamps, to ensure performance and interchangeability. The data given also provide the basis for the electrical requirements for ballasts and ignitors, as well as the lamp-related requirements for luminaires. This standard covers only single-ended HPS lamps. Lamps with internal starting devices are not covered. This standard does include "improved color" HPS lamps (those lamps that have a color rendering index ≥ 60 and that operate on the same ballasts as the conventional lamps that they are intended to replace). However, color is not a standardized parameter. Luminous flux is not a standardized parameter either. This standard covers only 60 Hz operation of HPS lamps, on ballasts designed for HPS lamps.
