Packing

Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office.

By agreement we will take packing material back, if it is sorted. You must bear the costs of transport. For packing

material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any

costs incurred.

Glossary

Typical Values: Due to the special conditions of the manufacturing processes of LED, the typical data or

calculated correlations of technical parameters can only reflect statistical figures. These do not necessarily

correspond to the actual parameters of each single product, which could differ from the typical data and calculated

correlations or the typical characteristic line. If requested, e.g. because of technical improvements, these typ. data

will be changed without any further notice.
