ENERGY PERFORMANCE OF LAMP CONTROLGEAR –
Part 2: Controlgear for high intensity discharge lamps
(excluding low-pressure mercury fluorescent lamps) –
Method of measurement to determine the efficiency of controlgear
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 redline version of the official IEC Standard allows the user to identify the changes made
to the previous edition IEC 62442-2:2018. A vertical bar appears in the margin wherever a
change has been made. Additions are in green text, deletions are in strikethrough red text.

IEC 62442-2 has been prepared by subcommittee 34C: Auxiliaries for lamps, of IEC technical
committee 34: Lighting. It is an International Standard.
This third edition cancels and replaces the second edition published in 2018. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the title of Part 2 has been modified;
b) this edition has been harmonized with IEC 62442-1 and IEC 62442-3;
c) the reference to and use of the measurement methods for non-active power consumption in
accordance with IEC 63103 have been added.
The text of this International Standard is based on the following documents:
Draft Report on voting
34C/1546/FDIS 34C/1549/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.

described in greater detail at www.iec.ch/standardsdev/publications.
A list of all parts in the IEC 62442 series, published under the general title Energy performance
of lamp controlgear, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or

ENERGY PERFORMANCE OF LAMP CONTROLGEAR –

Part 2: Controlgear for high intensity discharge lamps
(excluding low-pressure mercury fluorescent lamps) –
Method of measurement to determine the efficiency of controlgear

1 Scope
This part of IEC 62442 defines a measurement method of the power losses of electromagnetic
controlgear, the total input power and the standby power of electronic controlgear for high
intensity discharged discharge lamps (excluding low-pressure mercury fluorescent lamps). A
calculation method of the efficiency of controlgear for high intensity discharged discharge
lamp(s) is also defined.
It is assumed that the controlgear are designed for use on DC supplies up to 1 000 V and/or
AC supplies up to 1 000 V at 50 Hz or 60 Hz.
This document applies to electrical controlgear-lamp circuits comprised solely of the controlgear
and of the lamp(s).
NOTE Requirements for testing individual controlgear during production are not included.
This document specifies the measurement method for the total input power, the standby power
and the calculation method of the lamp controlgear efficiency for all controlgear sold for
domestic and normal commercial purposes operating with high intensity discharge lamps.
This document does not apply to:
– controlgear which form an integral part of lamps;
– controlgear circuits with capacitors connected in series;
– controllable electromagnetic controlgear.
