Description / Abstract: This standard sets forth the physical and electrical characteristics of the principal types of fluorescent lamps intended for application on conventional instant-start circuits. Lamp specifications for both the lamp itself and the interactive features of lamp and ballast are given.

Lamps designed primarily for operation on other types of circuits such as preheat (switch) start and rapid start are specified in other lamp standards. See clause 3.

Lamps for conventional systems relying on auxiliary support from external ballasts are described. The lamps are those designed for 60 Hz operation.

Lamp color is not specified herein.

Certain lamp types covered in this standard may be similar to those in IEC Publication 81. However, additional types are included that are used only in North America and are not specified in the IEC standard.
