Both will not be repeated here. The harmonic content is defined as the R. 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.

For dated references, only the edition cited applies. Life is always published in combination with the failure rate see NOTE 4 and 3. For that reason this standards relies on approximation methods to determine the expected life Oec or L70 of any self-ballasted LED lamp. 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.

Dedicated information on the chosen percentage is to be provided by the manufacturer. Stable operation has been reached when the temperature of the LED lamp is not increasing more than 5 K per h. Lamps which are intended for retrofit purposes shall 626112 equipped with adequate means of cooling. 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.
Annex B has been reserved for a description of an improved method as compared to CIE For undated references, the latest edition of the referenced document including any amendments applies. Reference is made to document CIE NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure. A self-ballasted LED-lamp is considered having passed the test when the following criteria have been met: In addition the following definitions are given.
L70, F50 or L50, F Tolerances are based on the CIE MacAdam ellipses as normally applied for ic fluorescent lamps and other discharge lamps.
Comments and observations to the comments were considered at that meeting and are incorporated in the CD. In the case of a voltage range, measurements shall be carried out at the mean value.
General requirements and tests. For relevant standards see Bibliography. Recommendations for whole product testing or batch testing are under consideration. 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 The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor 3.
For non-professional purposes, column Aand for professional purposes, column B is applicable. 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 insight as to the reliability of the measured values. For compliance with EMC requirements reference is made to regional requirements. 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.
All tests shall be carried out at rated frequency.
At the end of this time, and after cooling down to room temperature, the lamp shall remain alight for at least 15 min. NOTE 2 The actual luminous intensity coupled to a specific beam angle 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 by the manufacturer.

The definition under 3. For normative references, see IEC A fast initial decrease in lumen output does not automatically imply that a particular LED will not make its rated life.
Additionally, the following references are applicable: All LED lamps in the test sample must pass these post treatment criteria. At the end of these tests a and b the LED lamp shall operate and 626112 alight for 15 min and show no physical effects of the temperature cycling such as cracks or delaminating of the label.
The actual LED behavior with regard to lumen maintenance may differ considerably per type and per manufacturer. Marking according to one of both columns is required.
Note Method of measuring the luminous flux of LED lamps is under discussion. Five such cycles shall be carried out. Both elements are tested. 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.
