SELF-BALLASTED LED-LAMPS
FOR GENERAL LIGHTING SERVICES –
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 62612 has been processed by subcommittee 34A: Lamps, of IEC technical
committee 34: Lamps and related equipment.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
34A/1318/PAS 34A/1325/RVD
Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.

publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.

SELF-BALLASTED LED-LAMPS
FOR GENERAL LIGHTING SERVICES –
Performance requirements
1 General
1.1 Scope
This PAS specifies the performance requirements for self-ballasted LED lamps with a supply
voltage up to 250 V, together with the test methods and conditions required, intended for
domestic and similar general lighting purposes, having:
– a rated wattage up to 60 W;
– a rated voltage of up to 250 V AC or DC;
1)
– a lamp cap according to IEC 62560 .
The requirements of this PAS relate to type testing.
This PAS does not cover self-ballasted LED lamps that intentionally produce tinted or
coloured light neither does it cover OLEDs.
Recommendations for whole product testing or batch testing are under consideration.
)
1
These performance requirements are additional to the requirements in IEC 62560 (safety
standard for self-ballasted LED lamps).
NOTE When operated in a luminaire, the claimed performance data can deviate from the values established via
this PAS.
1.2 Statement
It may be expected that self-ballasted LED lamps which comply with this PAS will start and
operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage and at an
ambient air temperature of between –10 °C and 40 °C and in a luminaire complying with
IEC 60598-1.
For compliance with EMC requirements, reference is made to regional requirements. For
relevant standards, see Bibliography.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition

3 Terms and definitions
For the purposes of this PAS, the following terms and definitions apply.
For terms and definitions in the field of LED and LED modules, reference is made to
IEC 62504, which is currently in preparation, and IEC 60050-845. Both will not be repeated
here.
3.1
self-ballasted LED-lamp
unit which cannot be dismantled without being permanently damaged, provided with a lamp
cap conforming to IEC 60061-1 and incorporating a LED light source and any additional
elements necessary for starting and stable operation of the light source
3.2
type
LED lamps that, independent of the type of cap, have an identical photometric and electrical
rating
3.3
rated value
quantity value for a characteristic of a LED-lamp for specific operating conditions
The value and the conditions are specified in this PAS, or assigned by the manufacturer or
responsible vendor.
3.4
test voltage
voltage at which tests are carried out
3.5
lumen maintenance
luminous flux at a given time in the life of a LED-lamp divided by the initial value of the
luminous flux of the lamp and expressed as a percentage of the initial luminous flux
3.6
initial values
photometric and electrical characteristics at the end of the ageing period and/or stabilization
time
3.7
life (of an individual LED-lamp)
length of time during which a complete LED-lamp provides more than 50 % (or 70 %
alternatively; see Note 3) of the rated luminous flux, under standard test conditions
A LED-lamp has thus reached its end of life when it no longer provides 50 % (or 70 %
alternatively) of the rated luminous flux. Life is always published in combination with the
failure rate (see Note 4 and 3.9).

PAS 62612 © IEC:2009(E) – 7 –
NOTE 1 LED lamps have a different end of life characteristic than conventional lamps, because they are not
subject to sudden lamp failure but will typically dim over time in a gradual way.
NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure. The definition under 3.7
implies that a LED-lamp giving no light at all, due to electronic driver 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.
NOTE 3 The maximum lumen maintenance reduction figure may vary depending on the application of the LED
lamp. This PAS uses a value of 50 % (L ) as an example, which is often used for consumer applications. For
50
professional applications, a lumen maintenance figure of 70 % (L ) can be chosen. Dedicated information on the
70
chosen percentage is to be provided by the manufacturer.
NOTE 4 End of lamp life is normally determined when 50 % of the lamps has failed, indicated in combination with
the chosen lumen maintenance value: L ,
