A fast initial decrease in lumen output does not automatically imply that a particular LED will not make its rated life. A self-ballasted LED-lamp is considered having passed the test when the following criteria have been met: The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor 3.
You may not 662612 or “mirror” the file or printed version of the document, or any part of it, for any other purpose without permission 6262 writing from IEC. All tests shall be carried out at rated frequency. Five such cycles shall be carried out.
For that reason this standards relies on approximation iwc to determine the expected life L50 or L70 of any self-ballasted LED lamp.
Additionally, the following references are applicable: 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. At the end of this time, and after cooling down to room temperature, the lamp shall remain alight for at least 15 min. Lamps which are intended for retrofit purposes shall be equipped with adequate means of cooling. NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure.
General requirements and tests. Note Method of measuring the luminous flux of LED lamps is under discussion.
NOTE 2 The actual luminous intensity coupled to a specific beam eic is not an element of this performance standard, but the related 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 iex the manufacturer.

Marking according to one of 62621 columns is required. Annex B has been reserved for a description of an improved method as compared to CIE Both elements are tested. In the case of a voltage range, measurements shall be carried out at the mean value. The actual LED behavior with regard to lumen maintenance may differ considerably per type and per manufacturer.
IEC System of Conformity Assessment Schemes
For compliance with EMC requirements reference is made to regional requirements. 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. This will give additional ieec as to the reliability of the measured values.

Stable operation has been reached when the temperature of the LED lamp is not increasing more than 5 K per h. Both will not be repeated here. Life is always published in combination with the failure rate see NOTE 4 and 3.

The definition under 3. For non-professional purposes, column Aand for professional iiec, column B is applicable. Tolerances are based on the CIE MacAdam ellipses as normally applied for compact fluorescent lamps and other discharge lamps.
Comments and observations to the comments were considered at that meeting and are incorporated in the CD. L70, F50 or L50, F All LED lamps in the test sample must pass these post treatment criteria.

Reference is made to document CIE In addition the following definitions are given. These performance requirements ief additional to the requirements in IEC for self-ballasted LED lamps NOTE 1 safety standard When operated idc a luminaire the claimed performance data can deviate from the values established via this standard. Dedicated information on the chosen percentage is to be provided by the manufacturer. Recommendations for whole product testing or batch testing are under consideration.
For normative references, see IEC For relevant standards see Bibliography. 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. 6612 undated references, the latest edition of the referenced document including any amendments applies.
