PERFORMANCE REQUIREMENTS
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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.

International Standard IEC 62717 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This edition includes the following significant technical changes with respect to
IEC PAS 62717.
• all terms and definitions are aligned with IEC 62504 and relevant documents of CIE.
For example, general terms like “rated value” are shifted to IEC 62504.
• a statement on the applicability on a population is included.
• the normative references are completed and cleaned from standards that are not in
use.
• with regard to EMC, references to harmonic currents are given.
• the change, which has an effect on most parts of the standard, is the split of failure
mechanisms into abrupt failures and luminous flux depreciation. Consequently, new
terms and definitions, new requirements for lumen maintenance and a complete new
structure and contents of Annex C are introduced.
• transition from t to t is made, with the background that there is not one t ,
pmax prated pmax
but a choice of t (rated) values, in combination with lifetime.
p
• places where to mark (product, packaging, data sheets) are changed, and as a
consequence of the split of failure mechanisms, new parameters are listed. Further,
changes in the endurance test (ramping speed of temperature) are reflected in
marking.
• the concept of displacement factor instead of power factor is introduced. This led to
new definitions, requirements and Annexes E and F.
• the requirements on luminous efficacy are changed.
• the requirements, associated with the family concept are reviewed.
• statistics, based on confidence intervals are removed. This concerns requirements and
limits for LED module power and luminous flux and deletion of Annex E.
• new requirements for lumen maintenance are introduced.
• as part of the endurance test, the maximum light decrease after accelerated operation
life test is now fixed.
• with regard to the discussion on type test and sample size, the number of pieces in a
test sample is drastically reduced, see Table 7.
• Annex A on measuring methods is completely restructured and reviewed, for example
for ambient temperature and for shortening of stabilisation time when conducting
subsequent light output measurements.
• for electrical characteristics, the ageing time may be chosen as 500 h.
• for photometric data file formats, reference is given to IEC 62722-1.
• mistakes in the photometric code (Annex D) are corrected.
• Annex G on optimised test duration is removed; instead, an INF sheet shall be
published.
• from the luminaire standard, a new Annex H on “Test equipment for temperature
measurement” is taken over.
• finally, the Bibliography is updated.

INTRODUCTION
The first edition of a performance standard (precursor: IEC PAS 62717) for LED modules for
general lighting applications acknowledges the need for relevant tests for this new source of
electrical light, sometimes called “solid state lighting”. The publication is closely related to
simultaneously developed performance standard publication (which also started with a
Publicly Available Specification) for luminaires in general (IEC 62722-1) and for LED-
luminaires (IEC 62722-2-1). Changes in the LED module standard will have an impact on the
luminaire standards and vice versa, due to the behaviour of LED. Therefore, in the
development of the present standard, a close collaboration between experts of both products
has taken place.
The provisions in the standard represent the technical knowledge of experts from the fields of
the semiconductor (LED chip) industry and of those of the traditional electrical light sources.
Three types of LED-modules are covered: with integral controlgear, with means of control on
board, but with separate controlgear (“semi-ballasted”), and with complete separate
controlgear.

LED MODULES FOR GENERAL LIGHTING –
PERFORMANCE REQUIREMENTS
1 Scope
1.1 General
This International Standard specifies the performance requirements for LED modules,
together with the test methods and conditions, required to show compliance with this
standard. The following types of LED modules are distinguished and schematically shown in
Figure 1:
Type 1: integrated LED modules for use on d.c. supplies up to 250 V or on a.c. supplies up to
1 000 V at 50 Hz or 60 Hz.
Type 2: LED modules operating with part of separate controlgear connected to the mains
voltage, and having further control means inside (“semi-integrated”) for operation under
constant voltage, constant current or constant power.
Type 3: LED modules where the complete controlgear is separate from the module (non-
integrated) for operation under constant voltage, constant current or constant power.
IEC
The power supply of the controlgear for semi-ballasted LED modules (Type 2) is an electronic device capable of
controlling currents, voltage or power within design limits.
The control unit of the controlgear for semi-ballasted LED modules (Type 2) is an electronic device to control the
electrical energy to the LEDs.
A LED module with separate controlgear can be either a non-ballasted LED module or a semi-ballasted LED
module.
Figure 1 – Types of LED modules
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are under consideration.

– 10 – IEC 62717:2014+AMD1:2015 CSV
© IEC 2015
This standard covers LED modules, based on inorganic LED technology that produces white
light.
Life time of LED modules is in most cases much longer than the practical test times.
Consequently, verification of manufacturer’s life time claims cannot be made in a sufficiently
confident way, because projecting test data further in time is not standardised. For that
reason the acceptance or rejection of a manufacturers life time claim, past an operational time
as stated in 6.1, is out of the scope of this standard.
Instead of life time validation this standard has opted for lumen maintenance codes at a
defined finite test time. Therefore, the code number does not imply a prediction of achievable
life time. The categories, represented by the code, are lumen-depreciation character
categories showing behaviour in agreement with manufacturer’s information which is provided
before the test is started.
In order to validate a life time claim, an extrapolation of test data is needed. A general method
of projecting measurement data beyond limited test time is under consideration.
The pass/fail criterion of the life time test as defined in this standard is different from the life
time metrics claimed by manufacturers. For explanation of recommended life time metrics,
see Annex C.
NOTE When modules are operated in a luminaire, the claimed performance data can deviate from the values
established via this standard due to e.g. luminaire components that impact the performance of the LED module.
The separate electronic controlgear for LED modules as mentioned in Type 2 and Type 3 is
not part of the testing against the requirements of this standard.
Protection for water and dust ingress, see B.3.
1.2 Statement
It may be expected that integrated LED modules which comply with this standard will start and
operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage. LED
modules with separate controlgear are expected to start and operate satisfactorily in
combination with the specified controlgear complying with IEC 61347-2-13 and IEC 62384. All
LED modules are expected to start and operate satisfactorily when operated under the
conditions specified by the LED module manufacturer and in a luminaire complying with
IEC 60598-1.
The requirements for individuals apply for 95 % of the population.

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

International Standard IEC 62717 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This edition includes the following significant technical changes with respect to
IEC PAS 62717.
• all terms and definitions are aligned with IEC 62504 and relevant documents of CIE.
For example, general terms like “rated value” are shifted to IEC 62504.
• a statement on the applicability on a population is included.
• the normative references are completed and cleaned from standards that are not in
use.
• with regard to EMC, references to harmonic currents are given.
• the change, which has an effect on most parts of the standard, is the split of failure
mechanisms into abrupt failures and luminous flux depreciation. Consequently, new
terms and definitions, new requirements for lumen maintenance and a complete new
structure and contents of Annex C are introduced.
• transition from t to t is made, with the background that there is not one t ,
pmax prated pmax
but a choice of t (rated) values, in combination with lifetime.
p
• places where to mark (product, packaging, data sheets) are changed, and as a
consequence of the split of failure mechanisms, new parameters are listed. Further,
changes in the endurance test (ramping speed of temperature) are reflected in
marking.
• the concept of displacement factor instead of power factor is introduced. This led to
new definitions, requirements and Annexes E and F.
• the requirements on luminous efficacy are changed.
• the requirements, associated with the family concept are reviewed.
• statistics, based on confidence intervals are removed. This concerns requirements and
limits for LED module power and luminous flux and deletion of Annex E.
• new requirements for lumen maintenance are introduced.
• as part of the endurance test, the maximum light decrease after accelerated operation
life test is now fixed.
• with regard to the discussion on type test and sample size, the number of pieces in a
test sample is drastically reduced, see Table 7.
• Annex A on measuring methods is completely restructured and reviewed, for example
for ambient temperature and for shortening of stabilisation time when conducting
subsequent light output measurements.
• for electrical characteristics, the ageing time may be chosen as 500 h.
• for photometric data file formats, reference is given to IEC 62722-1.
• mistakes in the photometric code (Annex D) are corrected.
• Annex G on optimised test duration is removed; instead, an INF sheet shall be
published.
• from the luminaire standard, a new Annex H on “Test equipment for temperature
measurement” is taken over.
• finally, the Bibliography is updated.

INTRODUCTION
The first edition of a performance standard (precursor: IEC PAS 62717) for LED modules for
general lighting applications acknowledges the need for relevant tests for this new source of
electrical light, sometimes called “solid state lighting”. The publication is closely related to
simultaneously developed performance standard publication (which also started with a
Publicly Available Specification) for luminaires in general (IEC 62722-1) and for LED-
luminaires (IEC 62722-2-1). Changes in the LED module standard will have an impact on the
luminaire standards and vice versa, due to the behaviour of LED. Therefore, in the
development of the present standard, a close collaboration between experts of both products
has taken place.
The provisions in the standard represent the technical knowledge of experts from the fields of
the semiconductor (LED chip) industry and of those of the traditional electrical light sources.
Three types of LED-modules are covered: with integral controlgear, with means of control on
board, but with separate controlgear (“semi-ballasted”), and with complete separate
controlgear.
+AMD2:2019 CSV © IEC 2019
LED MODULES FOR GENERAL LIGHTING –
PERFORMANCE REQUIREMENTS
1 Scope
1.2 General
This International Standard specifies the performance requirements for LED modules,
together with the test methods and conditions, required to show compliance with this
standard. The following types of LED modules are distinguished and schematically shown in
Figure 1:
Type 1: integrated LED modules for use on d.c. supplies up to 250 V or on a.c. supplies up to
1 000 V at 50 Hz or 60 Hz.
Type 2: LED modules operating with part of separate controlgear connected to the mains
voltage, and having further control means inside (“semi-integrated”) for operation under
constant voltage, constant current or constant power.
Type 3: LED modules where the complete controlgear is separate from the module (non-
integrated) for operation under constant voltage, constant current or constant power.
IEC
The power supply of the controlgear for semi-ballasted LED modules (Type 2) is an electronic device capable of
controlling currents, voltage or power within design limits.
The control unit of the controlgear for semi-ballasted LED modules (Type 2) is an electronic device to control the
electrical energy to the LEDs.
A LED module with separate controlgear can be either a non-ballasted LED module or a semi-ballasted LED
module.
Figure 1 – Types of LED modules
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are under consideration.

– 10 – IEC 62717:2014+AMD1:2015
+AMD2:2019 CSV © IEC 2019
This standard covers LED modules, based on inorganic LED technology that produces white
light.
Life time of LED modules is in most cases much longer than the practical test times.
Consequently, verification of manufacturer’s life time claims cannot be made in a sufficiently
confident way, because projecting test data further in time is not standardised. For that
reason the acceptance or rejection of a manufacturers life time claim, past an operational time
as stated in 6.1, is out of the scope of this standard.
Instead of life time validation this standard has opted for lumen maintenance codes at a
defined finite test time. Therefore, the code number does not imply a prediction of achievable
life time. The categories, represented by the code, are lumen-depreciation character
categories showing behaviour in agreement with manufacturer’s information which is provided
before the test is started.
In order to validate a life time claim, an extrapolation of test data is needed. A general method
of projecting measurement data beyond limited test time is under consideration.
The pass/fail criterion of the life time test as defined in this standard is different from the life
time metrics claimed by manufacturers. For explanation of recommended life time metrics,
see Annex C.
NOTE When modules are operated in a luminaire, the claimed performance data can deviate from the values
established via this standard due to e.g. luminaire components that impact the performance of the LED module.
The separate electronic controlgear for LED modules as mentioned in Type 2 and Type 3 is
not part of the testing against the requirements of this standard.
Protection for water and dust ingress, see B.3.
1.3 Statement
It may be expected that integrated LED modules which comply with this standard will start and
operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage. LED
modules with separate controlgear are expected to start and operate satisfactorily in
combination with the specified controlgear complying with IEC 61347-2-13 and IEC 62384. All
LED modules are expected to start and operate satisfactorily when operated under the
conditions specified by the LED module manufacturer and in a luminaire complying with
IEC 60598-1.
The requirements for individuals apply for 95 % of the population.
