This is the fifth revision of this Standard. Since its introduction in 1986 (IES LM-63-1986), this Standard has proved to be very useful and powerful. This revision further clarifies the standard to make its use as simple as possible. This update is intended as the final update to LM-63, which will put this file format into a long-term stability mode, ensuring it remains available as a reference. This Standard will eventually be replaced by a new XML-based file format, ANSI/IES TM-33-18, Standard Format for the Electronic Transfer of Luminaire Optical Data (see Informative References). However, both Standards are valid until this transition is complete and this Standard has been deprecated.
This document describes the standard data system and how to build a file using this system. The document addresses photometric data file formats specifically for data transfer, data storage and retrieval, and other data usage purposes.
