Overview

IEC 62722-2-1:2023 - "Luminaire performance – Part 2-1: Particular requirements – LED luminaires" is the international performance standard that specifies test methods, conditions and performance requirements for LED luminaires used in general lighting. This second edition (2023) replaces the 2014 edition and is a technical revision that clarifies temperature requirements for maintenance testing, aligns requirements with IEC 62717 (LED modules), and introduces a new Annex C on methods to calculate and measure parameters for extending electrical and photometric data.

Key topics and technical requirements

• Scope and applicability: Applies to LED luminaires for general lighting; semi-luminaires and luminaires designed for LED lamps (covered by IEC 62722-1) are excluded.
• Test conditions and types: Defines general test conditions and distinguishes luminaires using LED modules proven to comply with IEC 62717 (Type A) from those that are not (Type B).
• Electrical performance: Input power measurement procedures and electrical characteristics required for compliance.
• Photometric performance: Measurement and reporting of luminous flux, luminous intensity distribution, peak intensity, beam angle, and luminaire luminous efficacy.

INTRODUCTION
This standard is the conversion of IEC PAS 62722-2-1 into a full IEC performance standard for
LED luminaires for general lighting applications. This document acknowledges the need for
relevant tests for luminaires using this new source of LED as an electrical light source 1. This
document is seen in close context with the publication of simultaneously developed
performance standards for luminaires in general and for LED modules. This document does not
consider luminaires designed for LED lamps, which are covered in IEC 62722-1. Changes in
LED luminaires standards have an impact on LED module standards and vice versa, due to the
behaviour of LED. Therefore, for the development of this document, the mutual consultancy of
experts of both products has taken place.
The provisions in this document represent the technical knowledge of experts from the fields of
the semiconductor (LED chip) industry and of the traditional electrical light sources and
luminaires.
As this document has been simultaneously developed and edited with the standard for LED
modules (IEC 62717), where appropriate, the compliance of the LED modules with the
provisions of IEC 62717 can be transferred to the whole luminaire.

LUMINAIRE PERFORMANCE –
Part 2-1: Particular requirements – LED luminaires

1 Scope
This part of IEC 62722 specifies the performance requirements for LED luminaires, together
with the test methods and conditions, required to show compliance with this standard. It applies
to LED luminaires for general lighting purposes.
Semi-luminaires are not covered under the scope of this document.
For some types of luminaires (e.g. decorative or household) the provision of performance data
under the scope of this document is not appropriate. 2
In this document, the following types of LED luminaires are distinguished.
– Type A – Luminaires using LED modules where compliance with IEC 62717 has been
proven is given.
– Type B – Luminaires using LED modules where compliance with IEC 62717 has not been
proven is not given.
– Type C – Luminaires using a LED lamp and covered in IEC 62722-1.
Luminaires using an LED lamp are covered in IEC 62722-1 and are not within the scope of this
document. 3
The requirements of this document only relate to type testing.
This standard does not cover Type C luminaires.
This standard does not cover LED luminaires that intentionally produce coloured light, neither
does it cover luminaires using OLEDs (organic LEDs).
These performance requirements are additional to the requirements in IEC 62722-1, Clauses 1
to 9, except where in this Part 2-1 alternative methods of measurement or limits are specified. 4
As this standard has been simultaneously developed and edited with the standard for LED
modules, where appropriate the compliance of the LED modules to the provisions of IEC 62717
may be transferred to the whole luminaire.
This document covers LED luminaires using LED modules, based on inorganic LED technology
that produces white light. It does not cover luminaires using light sources based on OLED
technology (organic LED technology). 5
The lifetime of LED luminaires is in most cases much longer than the practical test times.
Consequently, the verification of manufacturer’s lifetime claims cannot be made in a sufficiently
confident way. For that reason the acceptance or rejection of a manufacturer’s life time claim,
past 25 % of rated life (with a maximum of 6 000 h), 6 is out of the scope of this document.
___________
To be published.
– 8 – IEC 62722-2-1:2023 CMV © IEC 2023
Instead of lifetime validation, this document has opted for lumen maintenance categories at a
defined finite test time. Therefore, the category number does not imply a prediction of
achievable lifetime. The categories are lumen-depreciation character categories showing
behaviour in agreement with the 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.
For explanation of recommended life time metrics see IEC 62717, Annex C.
It may be expected that LED luminaires 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 within the declared range of the manufacturer.
Evaluation of LOR (light output ratio) for LED luminaire is under consideration.

5 Not used General requirements 12
Performance requirements given in this document are additional to the requirements in
IEC 62722-1, except where, in this document, alternative methods of measurement or limits are
specified.
Luminaires are considered within the same family if they have:
– LED modules with the same method of control and operation (semi-integrated, integrated);
– LED modules with the same classification according to the method of installation (reference
is made to IEC 62031:2018, Clause 4) and using an LED module of the same family as
specified in IEC 62717:2014, 6.2 and the same class of protection against electrical shock;
– the same design characteristics distinguished either by common features of materials and
components, or by a method of processing and heat management or both.
Annex B provides an explanation of recommended lifetime metrics.
6 Test conditions
6.1 General test conditions
Test conditions for testing electrical and photometric characteristics, lumen maintenance and
life are given in Annex A. For a luminaire in a family of luminaires as described in Clause 5, the
electrical and photometric data can be calculated. When calculations are used or when
alternative colorimetric data is derived, the methods and conditions given in Annex C shall be
used. Annex C is only valid in the case of luminaires where a single LED module is used or
where all the LED modules are identical. 13
NOTE The applicability of Annex C to light sources where the light colour is obtained by mixing different spectra
emitted by different light sources can require more consideration than those provided by Annex C.
All tests are measured on "n" LED luminaires of the same type. The number "n" shall be a
minimum of products as given in Table 3. LED luminaires used in the endurance tests shall not
be used in other tests.
Each sample luminaire shall comply with all the relevant tests except for the tests of 10.3 where
one sample is required for each of the three separate tests mentioned in Table 2 and Table 3.
In order to reduce the time of testing, the manufacturer or responsible vendor may can submit
additional luminaires or parts of luminaires provided that these are of the same materials and
design as the original luminaire and that the results of the test are the same as if carried out on
an identical luminaire.
LED luminaires with dimming control shall be adjusted to maximum output for all tests.
LED luminaires with adjustable CCT shall be adjusted/ or set to one fixed value, as indicated
by the manufacturer or responsible vendor.
LED luminaires of linear geometry and variable length shall be tested at a length at which the
parameters are given (e.g. performance per x cm).
6.2 Luminaires using LED modules where compliance with IEC 62717 has been

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.

INTRODUCTION
This document acknowledges the need for relevant tests for luminaires using LED as an
electrical light source. This document is seen in close context with the publication of
simultaneously developed performance standards for luminaires in general and for LED
modules. This document does not consider luminaires designed for LED lamps, which are
covered in IEC 62722-1. Changes in LED luminaires standards have an impact on LED module
standards and vice versa, due to the behaviour of LED. Therefore, for the development of this
document, the mutual consultancy of experts of both products has taken place.
The provisions in this document represent the technical knowledge of experts from the fields of
the semiconductor (LED chip) industry and of the traditional electrical light sources and
luminaires.
As this document has been simultaneously developed and edited with the standard for LED
modules (IEC 62717), where appropriate, the compliance of the LED modules with the
provisions of IEC 62717 can be transferred to the whole luminaire.

LUMINAIRE PERFORMANCE –
Part 2-1: Particular requirements – LED luminaires

1 Scope
This part of IEC 62722 specifies the performance requirements for LED luminaires, together
with the test methods and conditions. It applies to LED luminaires for general lighting purposes.
Semi-luminaires are not covered under the scope of this document.
For some types of luminaires (e.g. decorative or household) the provision of performance data
under the scope of this document is not appropriate.
In this document, the following types of LED luminaires are distinguished.

– Type B – Luminaires using LED modules where compliance with IEC 62717 is not given.
Luminaires using an LED lamp are covered in IEC 62722-1 and are not within the scope of this
document.
The requirements of this document relate to type testing.
This document covers LED luminaires using LED modules, based on inorganic LED technology
that produces white light. It does not cover luminaires using light sources based on OLED
technology (organic LED technology).
The lifetime of LED luminaires is in most cases much longer than the practical test times.
Consequently, the verification of manufacturer’s lifetime claims is out of the scope of this
document.
Instead of lifetime validation, this document has opted for lumen maintenance categories at a
defined finite test time. Therefore, the category number does not imply a prediction of
achievable lifetime. The categories are lumen-depreciation character categories showing
behaviour in agreement with the manufacturer’s information which is provided before the test
is started.

5 General requirements
Performance requirements given in this document are additional to the requirements in
IEC 62722-1, except where, in this document, alternative methods of measurement or limits are
specified.
Luminaires are considered within the same family if they have:
– LED modules with the same method of control and operation (semi-integrated, integrated);
– LED modules with the same classification according to the method of installation (reference
is made to IEC 62031:2018, Clause 4) and using an LED module of the same family as
specified in IEC 62717:2014, 6.2 and the same class of protection against electrical shock;
– the same design characteristics distinguished either by common features of materials and
components, or by a method of processing and heat management or both.
Annex B provides an explanation of recommended lifetime metrics.
6 Test conditions
6.1 General test conditions
Test conditions for testing electrical and photometric characteristics, lumen maintenance and
life are given in Annex A. For a luminaire in a family of luminaires as described in Clause 5, the
electrical and photometric data can be calculated. When calculations are used or when
alternative colorimetric data is derived, the methods and conditions given in Annex C shall be
used. Annex C is only valid in the case of luminaires where a single LED module is used or
where all the LED modules are identical.

NOTE The applicability of Annex C to light sources where the light colour is obtained by mixing different spectra
emitted by different light sources can require more consideration than those provided by Annex C.
All tests are measured on "n" LED luminaires of the same type. The number "n" shall be a
minimum of products as given in Table 3. LED luminaires used in the endurance tests shall not
be used in other tests.
Each sample luminaire shall comply with all the relevant tests except for the tests of 10.3 where
one sample is required for each of the three separate tests mentioned in Table 2 and Table 3.
In order to reduce the time of testing, the manufacturer or responsible vendor can submit
additional luminaires or parts of luminaires provided that these are of the same materials and
design as the original luminaire and that the results of the test are the same as if carried out on
an identical luminaire.
LED luminaires with dimming control shall be adjusted to maximum output for all tests.
LED luminaires with adjustable CCT shall be adjusted or set to one fixed value, as indicated by
the manufacturer or responsible vendor.
LED luminaires of linear geometry and variable length shall be tested at a length at which the
parameters are given (e.g. performance per x cm).
6.2 Luminaires using LED modules where compliance with IEC 62717 is given
(Type A)
Only the tests for measurement of initial performance as detailed in 6.4 shall be conducted,
when the LED module is operated within its temperature limit t .
p
The information for luminaire design given in IEC 62717:2014, Clause B.1, requires LED
modules to be operated within their t temperature limit. The t temperature shall be measured
p p
in accordance with the thermal test procedure defined in IEC 60598-1:2020, 12.4, (normal
operation). When the luminaire is operating at its own maximum rated ambient performance
temperature value (t ), the t limit (for the declared performance – IEC 62717:2014, Table 2
q p
and IEC 62717:2014/AMD2:2019, Table 2) of LED modules operating inside the luminaire shall
not be exceeded. The test voltage for the luminaire shall be 1,00 times the rated voltage of the
luminaire. In luminaires intended to be supplied with constant current, the test current shall be
1,00 times the rated current of the luminaire.
For luminaires for road and street lighting and floodlights intended for outdoor use only, the
reduction of the measured temperature according to IEC 60598-2-3:2002, 3.12.1, and
IEC 60598-2-5:2015, 5.12.1, respectively, shall not be applied for the t temperature of the LED
p
module.
The ambient performance temperature t is measured in a draught-proof enclosure, as the air
q
temperature, at a position near one of the perforated walls on a level with the centre of the
luminaire, see IEC 60598-1, Clause K.1, item e).

tested n LED luminaires shall have passed the performance requirements. The parameter given
in Table 2 represents a replacement of the corresponding parameter given in IEC 62722-1.
NOTE As indicated in Clause 5 of this document, the performance requirements given in this Subclause 6.4 are
additional to the requirements in IEC 62722-1. Additional parameters or requirements not listed in Table 2 but given

Testing requirements for Type A LED luminaires will depend on the requirements of IEC 62717. It is not the
intention to re-measure the values of a product complying with its own standard. However where luminaires
combine different LED modules in one luminaire, or where secondary optics are added to the luminaire, certain
parameters can be required to be measured, e.g. if there is a mixing of colours, the final CRI and CCT shall
be measured in the luminaire.

The values of 9.1, 9.2 and 9.3 relate to the light source.

7 Input power
The provisions of IEC 62717:2014, Clause 7 apply to the LED luminaire. Power is measured at
the supply to the luminaire, see Figure 1. In case the power is not constant, the average of the
power is measured over an appropriate time by taking into account the nature of the variation.
NOTE The luminaire can contain components (e.g. digital controllers or sensor) which do not consume constant
power, but can be in the sleeping mode and then work and take power.

Measurement method of LED luminaire characteristics
A.1 General
The provisions of IEC 62717:2014, Clause A.1 and IEC 62717:2014/AMD2:2019, Clause A.1
apply to the LED luminaire, except that the luminaire shall be tested at the ambient temperature

manufacturer, a correction factor shall be established to correct the measured luminous flux
value at 25 °C to the luminous flux value at the declared ambient temperature. This shall be
done using relative photometry in a temperature controlled cabinet.
In addition, for LED luminaires, international and regional requirements for measurement
methods and provision of data can apply. The format of the data is optional.

Annex B
(informative)
Explanation of recommended lifetime metrics
B.1 General
The lifetime of LED luminaires can be far more than what practically can be verified with testing.
Furthermore the decrease in light output differs per manufacturer, making general prediction
methods difficult. This document has opted for lumen maintenance categories that cover the
initial decrease in luminous flux until an operational time as stated in 6.1. Because of this limited
test time, the claimed life of an LED luminaire cannot be confirmed nor rejected in most cases.
NOTE The useful life of a luminaire refers to the lumen maintenance projections of the LED light sources integrated
into that luminaire or to the number of hours that an LED luminaire will deliver a sufficient amount of light in a given
application.
Luminaire life, on the other hand, is linked with the reliability of the components of an LED luminaire as a system,
including the electronics, materials, housing, wiring, connectors, seals, and so on. The entire system lasts only as
long as the critical component with the shortest life, whether that critical component is a weather seal, an optical
element, an LED, or something else. From this point of view, LED light source
