Both will not be repeated here. Reference is made to document CIE Annex B has been reserved for a description of an improved method as compared to CIE Lamps which are intended for retrofit purposes shall be equipped with adequate means of cooling.
Marking according to one of both columns is required. In the case of a voltage range, measurements shall be carried out at the mean value.
The harmonic content is defined as the R. This will give additional insight as to the reliability of the measured values. At the end of this time, and after cooling down 62162 room temperature, the lamp shall remain alight for at least 15 min.

All LED lamps in the test sample must pass these post treatment criteria. For relevant standards see Bibliography.
See also the text under Clause 11 with regard to the indicated percentage of tested lamps of a total batch F50 or F10 that may fail the requirements of the test. All tests shall be carried out at rated frequency.

Tolerances are based on the CIE MacAdam ellipses as normally applied for compact fluorescent lamps and other discharge lamps. You may not copy or “mirror” the file or printed version of the document, or any part of it, for any other purpose without permission in writing from IEC. For normative references, see IEC For that reason this standards relies on approximation methods to determine the expected life L50 or L70 of any self-ballasted LED lamp.
Recommendations for whole product testing or batch testing are under consideration. L70, F50 or L50, F 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.
B Product datasheets 1 or leaflets x x x c Rated life and the related lumen maintenance factor Lx e Failure rate Fxcorresponding to the rated life f Lumen maintenance category Cat A to E, see Clause At the end of these tests idc and b the LED iecc shall operate and remain alight for 15 min and show no physical effects of the temperature cycling such as cracks or delaminating of the label.
Both elements are tested.
Life is always published in combination with the failure rate see NOTE 4 and 3. A fast initial decrease in lumen output does not automatically imply that a particular LED will not make its rated life.
In addition the following definitions are given. Additionally, the following references are applicable: The definition under 3. For undated references, the latest edition of the referenced document including any amendments applies. For compliance with EMC requirements reference is made to regional requirements. Comments and observations to the comments were considered at that meeting and are incorporated in the CD.

For non-professional purposes, column Aand for professional purposes, column B is applicable. NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure.
Stable operation has been reached when the temperature of the LED lamp is not increasing more than 5 K per h. It is permitted to download this electronic file, to make a copy and to print out the content for the sole purpose of preparing National Committee positions.
