ENERGY PERFORMANCE OF LAMP CONTROLGEAR –

Part 1: Controlgear for fluorescent lamps –
Method of measurement to determine the total input power
of controlgear circuits and 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.
IEC 62442-1 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) this edition has been harmonized with IEC 62442-2 and IEC 62442-3;
b) the reference to and use of the measurement methods for non-active power consumption in
accordance with IEC 63103 have been added.

responsible vendor and established under standard test conditions
Note 1 to entry: To express the "rated value" of a particular quantity, the term "value" is replaced by the quantity
name; for example, rated power, rated voltage, rated current, and rated temperature.
Note 2 to entry: For the different kinds of operation, rated electrical values are given on the lamp data sheets as:
− rated electrical values under "electrical characteristics", if the lamp is defined for 50 Hz/60 Hz operation only;
− rated electrical values under "electrical characteristics", if the lamp is defined for high frequency (≥ 20 kHz)

4.1 Ballast lumen factor
For every controlgear-lamp combination submitted for the test, the ballast lumen factor shall be
measured. The ballast lumen factor is defined in 3.11 and expressed as:

where
Light is the light output of the reference lamp connected to the reference ballast measured
ref
by photocell meter reading;
Light is the light output of the reference lamp connected to the controlgear under test
test
measured by photocell meter reading.
The ballast lumen factor shall be in the range of 0,925 to 1,075. A controlgear with a lower
ballast lumen factor is not suitable for testing. The upper limit of 1,075 may be exceeded, if the
value for maximum lamp operation current and maximum current in any lead to cathodes comply
with the rated value in IEC 60081 and IEC 60901.
4.2 Dimmable controlgear
A sufficient cathode temperature shall be produced by the heating circuit at any possible
dimming position within the available dimming range of the controlgear as specified in the
relevant data sheet in IEC 60081 and IEC 60901.
Dimmable controlgear shall be measured at 100 % and 25 % lumen output of the operated
lamp(s).
4.3 Multi-power and/or multi-number-lamp controlgear
Multi-power and multi-number-lamp controlgear shall be measured with all the possible lamp
power and number of lamp combinations. The manufacturer shall declare the relevant BLF for
each combination.
