This document is applicable to LED packages for general lighting services and LED packages
for horticultural lighting.

It specifies procedures and conditions for measuring the luminous flux maintenance of LED packages. It also provides the procedures and conditions (criteria) of projecting the long-term luminous flux maintenance based on limited luminous flux maintenance test data collected. Within the context of this document, wherever luminous flux measurement data is specified, radiant flux measurement data and photon flux measurement data can also be used.

These projection methods employ data collected as per ANSI/IES LM-80-20 (LM-80).

The long-term projection is based on the exponential-fit-function procedure of ANSI/IES TM-21-19 (TM-21) and gives an alternative border function procedure in the case where the exponential-fit-function of ANSI/IES TM-21-19 is not applicable.
