Lamps which are intended for retrofit purposes shall be equipped with adequate means of cooling.

For non-professional purposes, column Aand for professional purposes, column B is applicable. For relevant standards see Bibliography. Annex B has been reserved for a description of an improved method as compared to CIE NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure.
Unless otherwise specified for a specific purpose by the manufacturer or responsible uec, lamps shall be operated in free air in a vertical base-up position for all tests including lumen maintenance 6612. For undated references, the latest edition of the referenced document including any amendments applies. Tolerances are based on the CIE MacAdam ellipses as normally applied for compact fluorescent lamps and other discharge 66212.
In addition the following definitions are given. A self-ballasted LED-lamp is considered having passed the test when the following criteria have been met: NOTE 2 The actual luminous intensity coupled to a specific beam angle is not an element of this performance standard, but the iiec 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.
NOTE 1 LED lamps have a different end of life characteristic lec conventional lamps, because they are not subject to sudden lamp failure but will typically dim over time in a gradual way.
A fast initial decrease in uec output does not automatically imply that a particular LED will not make its rated life. 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.
For normative references, see IEC For compliance with EMC requirements reference is made to regional requirements. Additionally, the following references are applicable: General requirements and tests.

Life is always published in combination with the failure rate see NOTE 4 and 3. 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.
The harmonic content is defined as the R. Dedicated information on the chosen percentage is 66212 be provided by the manufacturer. The definition under 3. 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. 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. 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 actual Iecc behavior with regard to lumen maintenance may differ considerably per type and per manufacturer.
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. Comments and observations to the comments were considered at that meeting and are incorporated in the CD.
Reference is made to 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 ifc the temperature cycling such as cracks or delaminating of the label.
For dated references, only the edition cited applies. Marking according to one of 66212 columns is required. This will give additional insight as to the reliability of the measured values.
Both elements are tested. 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.

The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor 3. All LED lamps in 66212 test sample must pass these post treatment criteria. Note Method of measuring the luminous flux of LED lamps is under discussion. Recommendations for whole product testing or batch testing are under consideration. In the case of a voltage range, measurements shall be carried out at the mean value. All tests shall be carried out at rated frequency.
L70, F50 or L50, F Five such cycles shall be carried out.
