This standard is both a consolidation of several existing standards for Photographic, Stage and Studio-
8、class lamps, and a revision of those individual standards. The intent is to group them into a single standard by their common factor: the base. Suggestions for improvement of this standard should be submitted to the Secretariat C78, National Electrical Manufacturers Association, 1300 North 17th Stre

The lamps contained in this standard are not to be considered as interchangeable. Physically they will all fit the common socket used for these
20、 lamps. The photometry of each lamp is dependent upon the system for which it was designed and on the system in which it is used. A sample system and representative photometric values are found in the Annex. 2 Normative references lhe following standards contain provisions which, through reference i
21、n this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid.

27、e maximum safety during handling and use of the subject lamps, the following notices should be observed: 1. Tungsten-halogen lamps operate at high temperature and at intemal gas pressures above atmospheric pressure. Consequently, a lamp could shatter. Cettain lamps may also emit some amount of ultra
28、violet radiation. Therefore, a suitable protective shield, screening technique, or both shall be used with the luminaire to protect people and surroundings from both hazards. 2. Always read and observe the information contained in the lamp manufacture& caution notice. 7 Physical Characteristics Base
