RECOMMENDATIONS FOR SMALL RENEWABLE ENERGY AND
HYBRID SYSTEMS FOR RURAL ELECTRIFICATION –

Part 12-1: Selection of self-ballasted lamps (CFL) for rural electrification
systems and recommendations for household lighting equipment


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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 62257-12-1, which is a technical specification, has been prepared by IEC technical
committee 82: Solar photovoltaic energy systems.

INTRODUCTION
The IEC 62257 series intends to provide to different players involved in rural electrification
projects (such as project implementers, project contractors, project supervisors, installers,
etc.) documents for the setting up of renewable energy and hybrid systems with a.c. voltage
below 500 V, d.c. voltage below 750 V and power below 100 kVA.
These documents are recommendations:
• to choose the right system for the right place,
• to design the system,
• to operate and maintain the system.
These documents are focused only on rural electrification concentrating on but not specific to
developing countries. They must not be considered as all inclusive to rural electrification. The
documents try to promote the use of renewable energies in rural electrification; they do not
deal with clean mechanisms developments at this time (CO emission, carbon credit, etc.).
2
Further developments in this field could be introduced in future steps.
This consistent set of documents is best considered as a whole with different parts
corresponding to items for safety, sustainability of systems and at the lowest life cycle cost as
possible. One of the main objectives is to provide the minimum sufficient requirements,
relevant to the field of application that is: small renewable energy and hybrid off-grid systems.
The purpose of this part of IEC 62257 is to compile specifications and recommendations for
lighting materials, involved in decentralized rural electrification.
This document is also linked to other parts of IEC 62257 series namely IEC 62257-1, IEC
62257-2 to IEC 62257-6 and IEC 62257-7 to IEC 62257-13.

RECOMMENDATIONS FOR SMALL RENEWABLE ENERGY AND
HYBRID SYSTEMS FOR RURAL ELECTRIFICATION –

Part 12-1: Selection of self-ballasted lamps (CFL) for rural electrification
systems and recommendations for household lighting equipment



1 Scope
Decentralized Rural Electrification Systems (DRES) are designed to supply electric power to
sites which are not connected to a large interconnected system, or a national grid.
As described in the IEC 62257-1, these systems include:
• an electrical power production subsystem;
• a secondary grid for sharing/distributing this power, when the system is a collective
electrification system (microgrid);
• a subsystem for utilizing this electrical power as a demand subsystem including the in-
house wiring and user’s electrical appliances.
In many situations, lighting is the most expected application of the rural electrification process

and the first application that the users may afford.
For a given lighting performance, the electrical characteristics of the lamps may vary,
particularly the power factor and the harmonic content.
On large grids, the impact of these characteristics is generally not a major issue. In the
context of the electrification systems considered in the IEC 62257 series, the main
applications are lighting and TV. In these small systems, the power factor and the harmonic
content of the supplied appliances have a high impact on the design and the sizing of the
production and distribution subsystems as well as on the quality of the service provided.
Project implementers cannot afford an over-sizing of any part of the system. For this reason,
they have to make sure that the selected appliances have characteristics which do not
adversely affect the cost of the equipment necessary to provide the quality of service required
by the General Specification of the project.
Some relevant products are available on the market (high power factor and low harmonic
content).The purpose of this technical specification is to help project implementers to
discriminate, in a potential sourcing panel, the models of lamps which could have the lowest
impact on the whole system (generation and distribution subsystems).
This specification deals with integral compact fluorescent technology lamps:
• power less than 60 W;
• with an Edison screw E27 or bayonet B22 cap;
• with nominal voltage from 100 V to 250 V a.c.
IEC 60969 specifies the performance requirements together with the test methods and
conditions required to show compliance of tubular fluorescent and other gas-discharge lamps
with integrated means for controlling starting and stable operation (self-ballasted lamps)
intended for domestic and similar general lighting purpose. This specification must be
considered as the reference for the manufacturers.

TS 62257-12-1 © IEC:2007(E) – 7 –
This technical specification proposes comparative tests that could be particularly useful for
project implementers to test in laboratories of developing countries the capability of products
to be used for their project. The tests can be performed locally, as close as possible of the
real site operating conditions. This technical specification does not cover other lamp
technologies (e.g. d.c. lamps, leds, etc ) however similar principles can be used for such
comparative testing.
Additionally some recommendations are suggested in Annex A in order to enhance the
performances or effectiveness of the lighting sources using a luminaire.
This specification is not a type approval standard. It is a technical specification to be used as
guidelines and does not replace any existing IEC standard on lamps.
