The above Type Numbers represent the order groups which include only a few brightness groups (see page 5). Only one group will be shipped on each
packing unit (there will be no mixing of two groups on each packing unit). E. g. LY R971-HL-1 means that only one group H, J, K, L will be shippable for
any packing unit. In order to ensure availability, single brightness groups will not be orderable.
Die oben genannten Typbezeichnungen umfassen die bestellbaren Selektionen. Diese bestehen aus wenigen Helligkeitsgruppen (siehe Seite 5). Es
wird nur eine einzige Helligkeitsgruppe pro Verpackungseinheit geliefert. Z. B. LY R971-HL-1 bedeutet, dass in einer Verpackungseinheit nur eine der
Helligkeitsgruppen H, J, K, L enhalten ist. Um die Liefersicherheit zu gewährleisten, können einzelne Helligkeitsgruppen nicht bestellt werden.
