A fast initial decrease in lumen output does not automatically imply that a particular LED will not make its rated life. 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.

Recommendations for whole product testing or batch testing are under consideration. Additionally, the following references are applicable: The actual LED behavior with regard to lumen maintenance may differ considerably per type and per manufacturer.
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. 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.
A self-ballasted LED-lamp is considered having passed the test when the following criteria have been met: Annex B has been reserved for a description of an improved method as compared to CIE Reference is made 66212 document CIE At the end of these tests a and b the LED lamp shall operate and remain alight for 15 min and show no physical effects of the temperature cycling oec as cracks or delaminating of the label.

Both will not be repeated here. Five such cycles shall be carried out. The harmonic content is defined as the R. Marking according to one of both columns is required. Comments and observations to the comments were considered at that meeting and are incorporated in the CD.
Unless otherwise specified for a specific purpose by the manufacturer or responsible vendor, lamps shall be operated in free air in a vertical base-up position for all tests including lumen maintenance tests. Lamps which are intended for retrofit purposes shall be equipped with adequate means of cooling. The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor 3. For compliance with EMC requirements reference is made to regional requirements.
These performance requirements are additional to the requirements in IEC for self-ballasted LED lamps NOTE 1 safety standard When operated in a luminaire the claimed performance data can deviate from the values established via this standard. Life is always published in combination with the failure rate see NOTE 4 and 3. In addition the following definitions are given.
This will give additional insight as to the reliability of the measured values. For undated references, the latest edition of the referenced document including any amendments applies.
For non-professional purposes, column Aand for professional purposes, column B is applicable.

General requirements and tests. In the case of a voltage range, measurements shall be carried out at the mean value. The definition under 3. NOTE 2 The actual luminous intensity coupled to a specific beam angle is not an element of this performance standard, but the idc luminous flux from which the beam intensity and angle are originated is subject of further testing; via calculation it can be determined whether the rated luminous intensities are realistic within the beam angle specified by the manufacturer.
For normative references, see IEC Note 26612 of measuring the luminous flux of LED lamps is under discussion. Dedicated information on the chosen percentage is to be provided by the manufacturer.
All tests shall be carried out at rated frequency. 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 Isc.

L70, F50 or L50, F At the end of this time, and after cooling down to room temperature, the lamp shall remain alight for at least 15 min. For that reason this standards relies on approximation methods to determine the expected life L50 or L70 of any self-ballasted LED lamp.
For dated references, only the edition cited applies.
All LED lamps in the test sample must pass these post treatment criteria. 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 ief is not increasing more than 5 K per h. Tolerances are based on the CIE MacAdam ellipses as normally applied for compact fluorescent lamps and other discharge lamps.
