NEMA Publishes ANSI_ANSLG C78.390-2006, Method Of Designation For Electric Lamps, Miniature And Sealed-Beam Incandescent Lamps

ROSSLYN, Va., September 14, 2006. NEMA, on behalf of the American National Standards Lighting Group, (ANSLG) has published ANSI_ANSLG C78.390-2006, American National Standard for Electric Lamps-Method of Designation for Electric Lamps, Miniature and Sealed-Beam Incandescent Lamps.

This standard describes a voluntary system for the method of designation of miniature and sealed-beam lamps. The method is intended to provide lamp manufacturers a means to request a designation. The purpose of the designation system defined by this standard is to provide the global lamp industry a convenient lamp identification that may be used for both manufacturing and product usage. The designation will provide, for the user, the interchangeability of lamps that bear the same designation.

"This standard was updated as part of the ongoing effort to make these standards relevant to current industry needs and practices," says Dennis Holt, Technical Coordinator of the C78 Work Group 07 (Miniature Lamps), which is the expert group to the Accredited Standards Committee on Electric Lamps. "The 2006 edition incorporates changes to accommodate new light sources, e.g., light emitting diode (LED) technology. Included in this edition is an update of the administrative practice relative to this lamp code designation system."
