LED PACKAGES – LONG-TERM LUMINOUS AND
RADIANT FLUX MAINTENANCE PROJECTION

AMENDMENT 1

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 63013:2017 has been prepared by subcommittee 34A: Electric light
sources, of IEC technical committee 34: Lighting.
The text of this Amendment is based on the following documents:
Draft Report on voting
34A/2233(F)/CDV 34A/2253/RVC

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Amendment is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available

at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications/.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

___________

1 Scope
Replace the existing paragraphs with the following new paragraphs:
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.

2 Normative references
Replace the existing second, third and fourth references with the following two new references:
1
ANSI/IES TM-21-19 , Technical Memorandum: Projecting Long Term Lumen, Photon, and
Radiant Flux Maintenance of LED Light Sources
ANSI/IES LM-80-20, Approved Method: Measuring Luminous Flux and Color Maintenance of
LED Packages, Arrays, and Modules

___________
1
 A revision of ANSI/IES TM-21-19, and a new ANSI approved IES calculation tool are under preparation by the
Illuminating Engineering Society. Publication of ANSI/IES TM-21-21 and the ANSI/IES TM-21-21 Calculator are
expected prior to 2021-12-31.
