Self-ballasted LED lamps for general lighting services with supply voltages > 50 V - Performance requirements

IEC 62612:2013 specifies the performance requirements, together with the test methods and conditions, required to show compliance of LED lamps with integral means for stable operation, intended for domestic and similar general lighting purposes, having:
- a rated power up to 60 W;
- a rated voltage of > 50 V a.c. up to 250 V a.c.;
- a lamp cap as listed in IEC 62560. This first edition of IEC 62612 cancels and replaces IEC/PAS 62612. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC/PAS 62612.
a) The standard explicitly states that real life time tests are not part of the test regime. Instead, a period of up to 6 000 h is chosen in order to assess manufacturers' claims of maintenance.
b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules) as far as possible. Examples are the family approach and the temperature measuring point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.
e) First requirements are given for setting the colour for colour adjustable lamps and the luminous flux level of dimmable lamps.
f) The structure of tests is clearly divided between requirement and compliance.
g) Statistical compliance is separated into individual and average.
h) Light output requirements are extended to luminous intensity distribution, peak intensity, beam angle and efficacy.
i) The use of the terms "correlated colour temperature" and "chromaticity coordinates" is corrected.
j) The number of tolerance categories is reduced from 8 to 4, and split between initial and maintained values.
k) Colour rendering is differently assessed at initial and maintained state.
l) Three lumen maintenance categories are given instead of five.
m) The endurance tests are completely re-established.
n) The verification (formerly: assessment) clause is completed.
o) Information for luminaire design is added.
p) Stabilisation is more precise (Annex A on the method of measuring lamp characteristics) and extension is made for the additional photometric and colorimetric parameters.
q) Annex B on measuring luminous flux is contained in Annex A. New Annex B provides the photometric code.
r) Further annexes are added: Annex C and D for displacement factor, Annex E for life time metrics/reliability and Annex F for examples of LED dies and LED packages. The contents of the corrigendum of October 2016 have been included in this copy.

Lampes à LED autoballastées pour l'éclairage général avec des tensions d'alimentation > 50 V - Exigences de performances

La CEI 62612:2013 spécifie les exigences de performances, ainsi que les conditions et les méthodes d'essais, requises pour assurer la conformité des lampes à LED à dispositif de stabilisation incorporé, destinées à l'éclairage domestique et à l'éclairage général similaire, ayant:
- une puissance assignée pouvant atteindre 60 W;
- une tension assignée comprise entre 50 V c.a. et 250 V c.a.;
- un culot de lampe tel qu'indiqué dans la CEI 62560. Cette première édition de la CEI 62612 annule et remplace la CEI/PAS 62612. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à la CEI/PAS 62612.
a) La norme indique explicitement que les essais de durée de vie réelle ne font pas partie du régime d'essais. Au lieu de cela, on choisit une période pouvant atteindre 6 000 h pour évaluer les déclarations de maintien données par un fabricant.
b) Des caractéristiques techniques ont été adaptées autant que possible à la CEI/PAS 62717 (performances des modules de LED). Des exemples incluent l'utilisation de familles et le point de mesure de la température.
c) Les exigences de marquage s'appliquent au boîtier et non au produit.
d) Le nombre de lampes à soumettre aux essais est spécifique aux essais.
e) Les premières exigences sont données pour régler la couleur des lampes à couleur ajustable et le niveau de flux lumineux des lampes à variation d'intensité.
f) La structure des essais est divisée entre exigences et conformité.
g) La conformité statistique est divisée en individuelle et moyenne.
h) Les exigences sur la lumière de sortie sont étendues à la distribution d'intensité lumineuse, l'intensité de crête, l'angle de faisceau et l'efficacité.
i) L'utilisation des termes "température de couleur proximale" et "coordonnées trichromatiques" est corrigée.
j) Le nombre de catégories de tolérance est réduit de 8 à 4 et divisé entre les valeurs initiales et valeurs de maintien.
k) Le rendu des couleurs est évalué différemment à l'état initial et à l'état de maintien.
l) Trois catégories de maintien de flux lumineux sont données au lieu de cinq.
m) Les essais d'endurance sont entièrement rétablis.
n) L'article sur la vérification (auparavant appelée évaluation) est complété.
o) Des informations pour la conception de luminaires sont ajoutées.
p) La stabilisation est plus précise (Annexe A sur la méthode de mesure des caractéristiques des lampes) et des paramètres photométriques et colorimétriques supplémentaires ont été ajoutés.
q) L'Annexe B sur la mesure du flux lumineux est incluse dans l'Annexe A. Une nouvelle Annexe B fournit le code photométrique.
r) D'autres annexes ont été ajoutées. L'Annexe C et l'Annexe D sur le facteur de déplacement, l'Annexe E sur les valeurs et la fiabilité de la durée de vie et l'Annexe F qui donne des exemples de puces de LED et de boîtier de LED. Le contenu du corrigendum d'octobre 2016 a été pris en considération dans cet exemplaire.

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.
International Standard IEC 62612 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This first edition of IEC 62612 cancels and replaces IEC/PAS 62612. This edition constitutes
a technical revision.
This edition includes the following significant technical changes with respect to
IEC/PAS 62612.
a) The standard explicitly states that real life time tests are not part of the test regime.
Instead, a period of up to 6 000 h is chosen in order to assess manufacturers’ claims of
maintenance.
b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules)
as far as possible. Examples are the family approach and the temperature measuring
point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.

INTRODUCTION
This International Standard is the first edition of a performance standard (precursor:
IEC/PAS 62612) for self-ballasted LED lamps for general lighting applications and
acknowledges the need for relevant tests for this new source of electrical light, sometimes
called “solid state lighting”.
The provisions in this 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.

62612  IEC:2013 – 7 –
SELF-BALLASTED LED LAMPS FOR GENERAL
LIGHTING SERVICES WITH SUPPLY VOLTAGES > 50 V –
PERFORMANCE REQUIREMENTS
1 Scope
This International Standard specifies the performance requirements, together with the test
methods and conditions, required to show compliance of LED lamps with integral means for
stable operation, intended for domestic and similar general lighting purposes, having:
• a rated power up to 60 W;
• a rated voltage of > 50 V a.c. up to 250 V a.c.;
• a lamp cap as listed in IEC 62560.
These performance requirements are additional to the safety requirements in IEC 62560.
The only feature provided by this standard, when applied for replacement purposes, is
information on maximum lamp outlines.
The requirements of this standard relate to type testing. This standard covers LED lamps that
intentionally produce white light, based on inorganic LEDs.
Recommendations for whole product testing or batch testing are under consideration.
The life time of LED lamps 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 manufacturer's life time claim, past an operational
time as stated in 7.1, 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, provided before
the test is started.
In order to validate a life time claim, several methods of test data extrapolation exist. 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 E.
NOTE When lamps 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 lamp.

For the purposes of this document, the terms and definitions given in IEC/TS 62504 and
IEC 60050-845 as well as the following apply.
3.1
rated value
quantity value for a characteristic of an LED lamp for specified operating conditions
Note 1 to entry: The value and the conditions are specified in this standard, or assigned by the manufacturer or
responsible vendor.
3.2
test voltage
voltage at which tests are carried out
Note 1 to entry: Specification of test voltage is made in A.2.

62612  IEC:2013 – 9 –
3.3
lumen maintenance (of an LED lamp)
luminous flux maintenance
ratio of the luminous flux emitted by an LED lamp at a given time in its life to its initial
luminous flux, the lamp being operated under specified conditions
Note 1 to entry: This ratio x is generally expressed in per cent.
Note 2 to entry: The lumen maintenance of an LED lamp is the effect of decrease of the lumen output of the LED(s)
or a combination of this with failure(s) of LED(s) if the lamp contains more than one LED.
[SOURCE: IEC 60050-845:1987, 845.07.65, modified — the term "LED" and the note 2 to
entry are added]
3.4
initial value
photometric, colorimetric and electrical characteristics at the end of the ageing period and
stabilisation time
3.5
maintained value
photometric, colorimetric and electrical characteristics at an operational time, including
stabilisation time
Note 1 to entry: The operational time is stated in 7.1.
3.6
life (of an individual LED lamp)
L
x
length of time during which an LED lamp provides at least claimed percentage of the initial
luminous flux, under standard conditions
Note 1 to entry: An LED lamp has thus reached its end of life, when it no longer provides claimed percentage of the
initial luminous flux. Life is always published in combination of life (L ) at lumen maintenance (x) and the failure
x
fraction (F ) (see 3.8)
y
Note 2 to entry: Any built-in electronic controlgear, however, may show a sudden end of life failure. The definition
3.6 implies that an LED lamp giving no light at all, due to an electronic failure, has actually reached end of life,
since it no longer complies with the minimum luminous flux level as declared by the manufacturer or responsible
vendor.
3.7
rated lamp life
length of time during which a population of LED lamps provides at least the claim for luminous
flux percentage x and less or equal the claim for failure fraction percentage y, as declared by
the manufacturer or responsible vendor
Note 1 to entry: For sample size see Clause 7.
Note 2 to entry: Notes to entry 1 and 2 of 3.6 apply.
Note 3 to entry: Rated lamp life is expressed in hours.
3.8
failure fraction at rated life
F
y
percentage y of a number of LED lamps of the same type, that at their rated life designates
the percentage (fraction) of failures
Note 1 to entry: This failure fraction expresses the combined effect of all components of an LED lamp including
mechanical components, as far as the light output is concerned. The effect of the LED could either be less light
than claimed or no light at all.

– 10 – 62612  IEC:2013
Note 2 to entry: For self-ballasted LED lamps normally a failure fraction of 10 % or/and 50 % are being applied,
indicated as F and/or F .
10 50
3.9
photometric code
colour designation of an LED lamp giving white light as defined by the correlated colour
temperature and the CIE 13.2:1974 general colour rendering index
Note 1 to entry: The definition of photometric code is given in IEC/TS 62504 as light colour designation.
Note 2 to entry: The definition of photometric code may be further reviewed with regard to IEC/TR 62732.
3.10
stabilisation time
time, which the LED lamp requires to obtain stable photometric conditions with constant
electrical input for each measurement
Note 1 to entry: An LED lamp may be regarded as stable at stable thermal conditions.
3.11
ageing
preconditioning period of the LED lamps before initial values are taken
3.12
type
LED lamp, representative of the production
3.13
family
group of LED lamps that have same design characteristics, distinguished by common features
of materials, components, and/or method of processing

6 Dimensions
The LED lamp dimensions shall comply with the requirements as indicated by the
manufacturer or responsible vendor. If an outline as per IEC 60630 is claimed, then the
maximum outlines shall not be exceeded.
If the luminaire itself or any covering (if applicable) does not interfere with the dimensions of
LED lamps, such lamps are also suitable as replacement.
Compliance is checked by inspection.
7 Test conditions
7.1 General test conditions
Testing duration is 25 % of rated life time up to a maximum of 6 000 h.
Additional LED lamps within the same family (see 3.13) may be subjected to decreased
testing duration. For identification of a family see Table 2, for details on sample sizes for
family testing see Table 6.
62612  IEC:2013 – 13 –
Test conditions for testing electrical and photometric characteristics, lumen maintenance and
life are given in Annex A.
All tests are conducted on n LED lamps of the same type. The number n shall be a minimum
of products as given in Table 6. LED lamps used in the endurance tests shall not be used in
other tests.
LED lamps with dimming control shall be adjusted to maximum light output for all tests.
LED lamps with adjustable colour point shall be adjusted/set to one fixed value as indicated
by the manufacturer or responsible vendor.
7.2 Creation of lamp families to reduce test effort
7.2.1 General
Lamp families have been created with the aim of guiding LED lamp manufacturers towards
platform designs and thus allowing the possibility to use data of the existing baseline product
that has already been tested for an operational period as stated in 7.1. The baseline product
is considered to be the first LED lamp complying with this standard and designated to be part
of the family.
7.2.2 Variations within a family
Each family of LED lamps requires a case-by-case consideration. The range of LED lamps
should be manufactured by the same manufacturer, under the same quality assurance
system. The type variations of the range (e.g. Correlated Colour Temperature (CCT), see
10.1) should be essentially identical with respect to materials used, components and
construction applied. Type test sample(s) should be selected with the cooperation of the
manufacturer and the testing station.
Requirements for the identification of a family of LED lamps for type testing are given in
definition 3.13 and used in Table 2.
The testing time may be reduced within a family down to 1 000 h in case variations of part
characteristics are within the conditions given in Table 2.

SELF-BALLASTED LED LAMPS FOR GENERAL
LIGHTING SERVICES WITH SUPPLY VOLTAGES > 50 V –
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 amendments has been prepared
for user convenience.
IEC 62612 edition 1.2 contains the first edition (2013-06) [documents 34A/1662/FDIS and
34A/1679/RVD] and its corrigendum 1 (2016-10), its amendment 1 (2015-10) [documents
34A/1824/CDV and 34A/1854/RVD] and its amendment 2 (2018-08) [documents 34A/2086/FDIS
and 34A/2097/RVD].
In this Redline version, a vertical line in the margin shows where the technical content is
modified by amendments 1 and 2. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this publication.

+AMD2:2018 CSV  IEC 2018
International Standard IEC 62612 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 62612.
a) The standard explicitly states that real life time tests are not part of the test regime.
Instead, a period of up to 6 000 h is chosen in order to assess manufacturers’ claims of
maintenance.
b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules)
as far as possible. Examples are the family approach and the temperature measuring
point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.
e) First requirements are given for setting the colour for colour adjustable lamps and the
luminous flux level of dimmable lamps.
f) The structure of tests is clearly divided between requirement and compliance.
g) Statistical compliance is separated into individual and average.
h) Light output requirements are extended to luminous intensity distribution, peak intensity,
beam angle and efficacy.
i) The use of the terms “correlated colour temperature” and “chromaticity coordinates” is
corrected.
j) The number of tolerance categories is reduced from 8 to 4, and split between initial and
maintained values.
k) Colour rendering is differently assessed at initial and maintained state.
l) Three lumen maintenance categories are given instead of five.
m) The endurance tests are completely re-established.
n) The verification (formerly: assessment) clause is completed.
o) Information for luminaire design is added.
p) Stabilisation is more precise (Annex A on the method of measuring lamp characteristics)
and extension is made for the additional photometric and colorimetric parameters.
q) Annex B on measuring luminous flux is contained in Annex A. New Annex B provides the
photometric code.
r) Further annexes are added: Annex C and D for displacement factor, Annex E for life time
metrics/reliability and Annex F for examples of LED dies and LED packages.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
In this standard, the following print types are used:
– requirements: roman type;
– test specifications: italic type;
– notes: small roman type.

INTRODUCTION
This International Standard is the first edition of a performance standard (precursor:
IEC/PAS 62612) for self-ballasted LED lamps for general lighting applications and
acknowledges the need for relevant tests for this new source of electrical light, sometimes
called “solid state lighting”.
The provisions in this 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.

INTRODUCTION to Amendment 2
This amendment includes:
a) Adjustment of Table 1 markings;
b) Bypassing thermal device during test ( 11.3.4);
c) Inclusion of LM-80 data;
d) Maintained CRI.

SELF-BALLASTED LED LAMPS FOR GENERAL
LIGHTING SERVICES WITH SUPPLY VOLTAGES > 50 V –
PERFORMANCE REQUIREMENTS
1 Scope
This International Standard specifies the performance requirements, together with the test
methods and conditions, required to show compliance of LED lamps with integral means for
stable operation, intended for domestic and similar general lighting purposes, having:
• a rated power up to 60 W;
• a rated voltage of > 50 V a.c. up to 250 V a.c.;
• a lamp cap as listed in IEC 62560.
These performance requirements are additional to the safety requirements in IEC 62560.
The only feature provided by this standard, when applied for replacement purposes, is
information on maximum lamp outlines.
The requirements of this standard relate to type testing. This standard covers LED lamps that
intentionally produce white light, based on inorganic LEDs.
Recommendations for whole product testing or batch testing are under consideration.
The life time of LED lamps 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 manufacturer's life time claim, past an operational
time as stated in 7.1, 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, provided before
the test is started.
In order to validate a life time claim, several methods of test data extrapolation exist. 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 E.
NOTE When lamps 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 lamp.
It can be expected that self-ballasted LED lamps, which comply with this standard will start
and operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage and at
an ambient air temperature between –20 °C and 40 °C and in a luminaire complying with
IEC 60598-1.
If a supplier claims suitability for operation at different conditions (for instance, at higher
voltage, temperature or humidity) then:

+AMD2:2018 CSV  IEC 2018
a) Lamps shall be tested under claimed different conditions; and
b) Lamps shall start and operate satisfactorily under claimed different conditions; and
c) Lamps shall meet the performance claims under the claimed different conditions, which
may differ from the general conditions for measurement specified in A.1.

For the purposes of this document, the terms and definitions given in IEC/TS 62504 and
IEC 60050-845 as well as the following apply.
3.1
rated value
quantity value for a characteristic of an LED lamp for specified operating conditions
Note 1 to entry: The value and the conditions are specified in this standard, or assigned by the manufacturer or
responsible vendor.
3.2

Note 1 to entry: Specification of test voltage is made in A.2.
3.3
lumen maintenance (of an LED lamp)
luminous flux maintenance
ratio of the luminous flux emitted by an LED lamp at a given time in its life to its initial
luminous flux, the lamp being operated under specified conditions
Note 1 to entry: This ratio x is generally expressed in per cent.
Note 2 to entry: The lumen maintenance of an LED lamp is the effect of decrease of the lumen output of the LED(s)
or a combination of this with failure(s) of LED(s) if the lamp contains more than one LED.
[SOURCE: IEC 60050-845:1987, 845.07.65, modified — the term "LED" and the note 2 to
entry are added]
3.4
initial value
photometric, colorimetric and electrical characteristics at the end of the ageing period and
stabilisation time
3.5

7 Test conditions
7.1 General test conditions
Testing duration is 25 % of rated life time up to a maximum of 6 000 h.
Additional LED lamps within the same family (see 3.13) may be subjected to decreased
testing duration. For identification of a family see Table 2, for details on sample sizes for
family testing see Table 6.
For LED lamps using LED modules where compliance with IEC 62717 has been
demonstrated, the test duration of 25 % of rated life time up to a maximum of 6 000 h may be
avoided, provided that the LED module operates in its temperature and current limits as
tested according to IEC 62717. The data for chromaticity and the lumen maintenance at 25 %
of rated life, maximum 6 000 h from the IEC 62717 test report, shall be taken and used to fulfil
the maintained value requirements of 10.1 and 11.2, respectively.
Alternatively, test data from ANSI/IES LM-80-15 shall be used for the derivation of maintained
values at 25 % of rated life, maximum 6 000 h, together with related compliance criteria, as
specified in Annex G.
Test conditions for testing electrical and photometric characteristics, lumen maintenance and
life are given in Annex A.
All tests are conducted on n LED lamps of the same type. The number n shall be a minimum
of products as given in Table 6. LED lamps used in the endurance tests shall not be used in
other tests.
LED lamps with dimming control shall be adjusted to maximum light output for all tests.
LED lamps with adjustable colour point shall be adjusted/set to one fixed value as indicated
by the manufacturer or responsible vendor.
7.2 Creation of lamp families to reduce test effort
7.2.1 General
Lamp families have been created with the aim of guiding LED lamp manufacturers towards
platform designs and thus allowing the possibility to use data of the existing baseline product
that has already been tested for an operational period as stated in 7.1. The baseline product
is considered to be the first LED lamp complying with this standard and designated to be part
of the family.
7.2.2 Variations within a family
Each family of LED lamps requires a case-by-case consideration. The range of LED lamps
should be manufactured by the same manufacturer, under the same quality assurance
system. The type variations of the range (e.g. Correlated Colour Temperature (CCT), see
10.1) should be essentially identical with respect to materials used, components and
construction applied. Type test sample(s) should be selected with the cooperation of the
manufacturer and the testing station.
Requirements for the identification of a family of LED lamps for type testing are given in
definition 3.13 and used in Table 2.

+AMD2:2018 CSV  IEC 2018
The testing time may be reduced within a family down to 1 000 h in case variations of part
characteristics are within the conditions given in Table 2.
Table 2 – Variations allowed within a family

allowed (see Note 2)
Housing/chassis, t (location and value given by the LED lamp supplier) and other components
LED
heat sink/heat
remain at the same or at a lower value, if the rated life time is the same or higher
management than the baseline product, as indicated and specified by the manufacturer or
responsible vendor (see also Note 1).
Optics (see Note 1) The test results showing the effect of optical material change shall be documented in
the manufacturer’s technical file.
LED package t remains at the same or at a lower value, if the rated life time is the same or
LED
higher than the baseline product. as indicated and specified by the manufacturer or
responsible vendor
Controlgear t remains at the same or at a lower value, if the rated life time is the same or
LED
higher than the baseline product, as indicated and specified by the manufacturer or
responsible vendor.
A statistical failure rate calculation based on an MTBF (mean time between failures)
calculation by the manufacturer shall show equal or lower failure rate of the
electronic controlgear.
NOTE 1 Optics include for instance secondary optics (lenses), reflectors, trims and gaskets and their
interconnections. The results relate to changes in luminous flux, peak luminous intensity, luminous intensity
distribution, beam angle, shift in colour co-ordinates, shift in CCT (see 10.1) and shift in colour rendering index
(CRI) (see 10.2).
NOTE 2 Any change on part tolerances are documented in the manufacturer’s technical file.
NOTE 3 Examples are under consideration.
7.2.3 Compliance testing of family members
The following performance characteristics of members within a family at initial and after
reduced testing time shall be in line with the values provided by the responsible manufacturer
or vendor of the lamp:
– chromaticity co-ordinates,
– colour rendering index,
– lumen maintenance code,
– results of accelerated operational life test.
Documentation of data shall be provided to the testing station in the manufacturer’s technical
file.
Compliance:
For all of the tested units in a sample, the measured values of an LED lamp (the initial and
maintained value) shall not move beyond the values indicated by the manufacturer or
responsible vendor. The measured values shall be of the same category or code as the
provided values or better. All the LED lamps in a sample shall pass the test.

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.
IEC 62612 edition 1.1 contains the first edition (2013-06) [documents 34A/1662/FDIS and
34A/1679/RVD] and its corrigendum 1 (2016-10), and its amendment 1 (2015-10) [documents
34A/1824/CDV and 65C/1854/RVD].

modified by amendment 1. Additions are in green text, deletions are in strikethrough red text. A
separate Final version with all changes accepted is available in this publication.

 IEC 2015
International Standard IEC 62612 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 62612.
a) The standard explicitly states that real life time tests are not part of the test regime.
Instead, a period of up to 6 000 h is chosen in order to assess manufacturers’ claims of
maintenance.
b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules)
as far as possible. Examples are the family approach and the temperature measuring
point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.
e) First requirements are given for setting the colour for colour adjustable lamps and the
luminous flux level of dimmable lamps.
f) The structure of tests is clearly divided between requirement and compliance.
g) Statistical compliance is separated into individual and average.
h) Light output requirements are extended to luminous intensity distribution, peak intensity,
beam angle and efficacy.
i) The use of the terms “correlated colour temperature” and “chromaticity coordinates” is
corrected.
j) The number of tolerance categories is reduced from 8 to 4, and split between initial and
maintained values.
k) Colour rendering is differently assessed at initial and maintained state.
l) Three lumen maintenance categories are given instead of five.
m) The endurance tests are completely re-established.
n) The verification (formerly: assessment) clause is completed.
o) Information for luminaire design is added.
p) Stabilisation is more precise (Annex A on the method of measuring lamp characteristics)
and extension is made for the additional photometric and colorimetric parameters.
q) Annex B on measuring luminous flux is contained in Annex A. New Annex B provides the
photometric code.
r) Further annexes are added: Annex C and D for displacement factor, Annex E for life time
metrics/reliability and Annex F for examples of LED dies and LED packages.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION
This International Standard is the first edition of a performance standard (precursor:
IEC/PAS 62612) for self-ballasted LED lamps for general lighting applications and
acknowledges the need for relevant tests for this new source of electrical light, sometimes
called “solid state lighting”.
The provisions in this 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.

SELF-BALLASTED LED LAMPS FOR GENERAL
LIGHTING SERVICES WITH SUPPLY VOLTAGES > 50 V –
PERFORMANCE REQUIREMENTS
1 Scope
This International Standard specifies the performance requirements, together with the test
methods and conditions, required to show compliance of LED lamps with integral means for
stable operation, intended for domestic and similar general lighting purposes, having:
• a rated power up to 60 W;
• a rated voltage of > 50 V a.c. up to 250 V a.c.;
• a lamp cap as listed in IEC 62560.
These performance requirements are additional to the safety requirements in IEC 62560.
The only feature provided by this standard, when applied for replacement purposes, is
information on maximum lamp outlines.
The requirements of this standard relate to type testing. This standard covers LED lamps that
intentionally produce white light, based on inorganic LEDs.
Recommendations for whole product testing or batch testing are under consideration.
The life time of LED lamps 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 manufacturer's life time claim, past an operational
time as stated in 7.1, 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, provided before
the test is started.
In order to validate a life time claim, several methods of test data extrapolation exist. 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 E.
NOTE When lamps 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 lamp.
It can be expected that self-ballasted LED lamps, which comply with this standard will start
and operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage and at
an ambient air temperature between –20 °C and 40 °C and in a luminaire complying with
IEC 60598-1.
If a supplier claims suitability for operation at different conditions (for instance, at higher
voltage, temperature or humidity) then:

 IEC 2015
a) Lamps shall be tested under claimed different conditions; and
b) Lamps shall start and operate satisfactorily under claimed different conditions; and
c) Lamps shall meet the performance claims under the claimed different conditions, which
may differ from the general conditions for measurement specified in A.1.

Note 1 to entry: Specification of test voltage is made in A.2.
3.3
lumen maintenance (of an LED lamp)
luminous flux maintenance
ratio of the luminous flux emitted by an LED lamp at a given time in its life to its initial
luminous flux, the lamp being operated under specified conditions
Note 1 to entry: This ratio x is generally expressed in per cent.
Note 2 to entry: The lumen maintenance of an LED lamp is the effect of decrease of the lumen output of the LED(s)
or a combination of this with failure(s) of LED(s) if the lamp contains more than one LED.

7 Test conditions
7.1 General test conditions
Testing duration is 25 % of rated life time up to a maximum of 6 000 h.
Additional LED lamps within the same family (see 3.13) may be subjected to decreased
testing duration. For identification of a family see Table 2, for details on sample sizes for
family testing see Table 6.
Test conditions for testing electrical and photometric characteristics, lumen maintenance and
life are given in Annex A.
All tests are conducted on n LED lamps of the same type. The number n shall be a minimum
of products as given in Table 6. LED lamps used in the endurance tests shall not be used in
other tests.
LED lamps with dimming control shall be adjusted to maximum light output for all tests.
LED lamps with adjustable colour point shall be adjusted/set to one fixed value as indicated
by the manufacturer or responsible vendor.
7.2 Creation of lamp families to reduce test effort
7.2.1 General
Lamp families have been created with the aim of guiding LED lamp manufacturers towards
platform designs and thus allowing the possibility to use data of the existing baseline product
that has already been tested for an operational period as stated in 7.1. The baseline product
is considered to be the first LED lamp complying with this standard and designated to be part
of the family.
7.2.2 Variations within a family
Each family of LED lamps requires a case-by-case consideration. The range of LED lamps
should be manufactured by the same manufacturer, under the same quality assurance
system. The type variations of the range (e.g. Correlated Colour Temperature (CCT), see
10.1) should be essentially identical with respect to materials used, components and
construction applied. Type test sample(s) should be selected with the cooperation of the
manufacturer and the testing station.
Requirements for the identification of a family of LED lamps for type testing are given in
definition 3.13 and used in Table 2.
The testing time may be reduced within a family down to 1 000 h in case variations of part
characteristics are within the conditions given in Table 2.
