    FOREWORD

    This Indian Standard (Part 2) was adopted by the Bureau of Indian Standards, after the draft finalized by the Electric Lamps and Their Auxiliaries Sectional Committee had been approved by the Electrotechnical Division Council.

    This standard specifies the performance requirements for self ballasted lamps for general lighting services for supplies > 50 V a.c. up to 250 V a.c at 50 Hz.;

    This standard is published in two parts. The other part in the series is: Part 1 Safety requirements

    This standard was first published in 2012. Revision of this standard has been undertaken to align it with latest development in this fileld.

    There will be and are already LED products in the market which substitute existing lamps, either as retrofit mains voltage incandescent or self ballasted fluorescent lamps or as replacement for tungsten halogen lamps below 50 V.

    This standard is based on IEC 62612 Self-ballasted LED lamps for general lighting services for voltage above 50 V Performance requirements issued by the International Electrotechnical Commission (IEC) with following modifications:

    a) Made applicable for supplies > 50 V a.c. up to 250 V a.c. at 50 Hz.;

    b) Schedule of type test and acceptance test has been incorporated; c) Ambient test condition changed to 27C;

    d) Selection of samples incorporated;

    e) Conditions of compliances incorporated; f) In Table 2 data related chromaticity co-ordinates and CCT values for 5 700 K added;

    g) Requirements of harmonics and p.f. have been added; and

    For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 Rules for rounding off numerical values (revised). The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

    Draft Indian Standard

    SELF-BALLASTED LED LAMPS FOR GENERAL LIGHTING SERVICES

    PART 2 PERFORMANCE REQUIREMENTS

    (First Revision)

    Last date for receipt of comments is 25-09-2015

    1 SCOPE

    This standard (Part 2) specifies the performance requirements for self-ballasted LED lamps with supplies > 50 V a.c. up to 250 V a.c at 50Hz , together with the test methods and conditions, required to show compliance with this standard, intended for domestic and similar general lighting purposes, having,

    a) a rated wattage from 1W to 25W ;

    b) a rated supplies > 50 V a.c. up to 250 V a.c.at 50Hz and

    c) a lamp cap according to IS 16102(Part 1) : 2012 Self-ballasted LED lamps for general lighting services: Part 1 Safety requirements.

    This standard does not cover self-ballasted LED-lamps that produce tinted or coloured light.

    This standard covers LED lamps that intentionally produce white light, based on inorganic

    LEDs.

    The only feature provided by this standard, when applied for replacement purposes, is

    information on maximum lamp outlines.

    These performance requirements are additional to the requirements given in IS 16102 (Part 1).

    NOTES

    1 When operated in a luminaire the claimed performance data can deviate from the values established in this standard e.g. Due to

    luminaire components that impact the performance of the lamp.

    2 Higher wattage lamp is under consideration.

    The life time of LED lamps is in most cases much longer than the practical test times.

    Consequently, verification of manufacturers life time claims cannot be made in a sufficiently confident way, because projecting test data further in time is not standardised. For that reason

    the acceptance or rejection of a manufacturer's life time claim, past an operational time is out of

    the scope of this standard.

    Instead of life time validation, this standard has opted for lumen maintenance codes at a defined

    finite test time. Therefore, the code number does not imply a prediction of achievable life time.

  • 2

    The categories, represented by the code, are lumen-depreciation character categories showing

    behaviour in agreement with manufacturers information, provided before the test is started. In order to validate a life time claim, several methods of test data extrapolation exist. A general

    method of projecting measurement data beyond limited test time is under consideration.

    The pass/fail criterion of the life time test as defined in this standard is different from the life

    time metrics claimed by manufacturers.

    NOTE When the lamps are used in the luminaire, the ambient temperature inside the luminaire is expected to be higher than the room ambient temperature. The procedure for design and measurement is covered in IS 10322 (Part 1).
