§ 22.17.2 of IEC 60598-2-22 states – “after these cycles (500 on-off’s) the supply shall again be reduced
& Y+ Q3 e) }% _1 ito 0,6 times rated voltage and the luminaire shall provide the rated lumen output after 60s or respective
lamp current after 0,5s for high-risk task area lighting luminaires”. Further, § 22.17.3 states – “after the
- A: S( r4 f3 M. F1 Ifinal lumen output measurement in accordance with § 22.17.2…”. It is fairly evident that the rated flux of
9 p3 D+ C$ f- r* B% ]the luminaire shall take into account the flux measurement after these 500 changeover operations. § 20 of
IEC 61347-2-7 states – “the changeover from normal supply to emergency mode and back shall be in
accordance with 22.17 of IEC 60598-2-22”. Does this mean that BLF should be measured after the 500
on-off’s changeover operations, exactly the same way as flux output for emergency luminaires specified
