4 General Description and Information
4.1 High-pressure sodium lamps may be operated on either series or multiple circuits with the use of the proper ballast.
4.2 The lamps in Tables 1 through 4 conform to the applicable requirements of ANSI C81 .61 and ANSI C78.42.
4.3 Lamps listed in Table 1 are intended for use with ballasts meeting the requirements of ANSI C82.4, applying to ballasts for high-pressure sodium lamps.
4.4 Lamps listed in Table 2 are intended for use with ballasts meeting the requirements of ANSI C82.7, applying to ballasts for mercury lamps.
4.5 Lamps of other wattages and color in combination with the proper ballast and with the same dimensional characteristics may be used in the same equipment, provided the operating temperature of the alternate lamp-ballast combinations do not exceed those of the lamp-ballast combinations used in the original equipment.
4.6 Users should consult their selected lamp manufacturer for type availability and exceptions to the appropriate lamp information table.
4.7 Lamp bases of brass or a corrosion resistant alloy are recommended. Consult the manufacturer for availability.ANSI NEMA C136.19 pdf download.
