scope:

This standard specifies performance requirements for non-integrated LED lamps intended for general lighting purposes, having : - a rated wattage up to 60 W - a rated voltage up to 120 V ripple free d.c. - a lamp cap as listed in IEC 62663-1 These performance requirements are additional to the safety requirements in IEC 62663-1. The requirements of this standard relate only to type testing. The requirements of this standard relate to type testing. This standard covers LED lamps that intentionally produce white light, based on inorganic LEDs. Recommendations for whole product testing or batch testing are under consideration. The life time of LED lamps is in most cases much longer than the practical test times. Consequently, verification of manufacturer's life time claims cannot be made in a sufficiently confident way, because projecting test data further in time is not standardised. For that reason the acceptance or rejection of a manufacturer's life time claim, past an operational time as stated in 7.1, is out of the scope of this standard. Instead of life time validation, this standard has opted for lumen maintenance codes at a defined finite test time. Therefore, the code number does not imply a prediction of achievable life time. The categories, represented by the code, are lumen-depreciation character categories showing behaviour in agreement with manufacturer's information, provided before the test is started.
