ROSSLYN, VA, October 25, 2006-The National Electrical Manufacturers Association (NEMA), on behalf of the American National Standard Lighting Group (ANSLG) has published ANSI_ANSLG C78.41-2006, American National Standard for Electric Lamps-Guidelines for Low Pressure Sodium Lamps.
This standard describes the physical and electrical requirements of the principal types of single-ended low pressure sodium lamps. The electrical data provides the specific basis for ballast requirements for these lamps. ANSI_ANSLG C78.41-2006 is a revision of ANSI C78.41-2001, and supersedes it.
The 2006 edition of ANSI_ANSLG C78.41 consists of three parts.
