Abstract	The aim of the LUMEN co-operation, supported by INFN, is to obtain ful experimental characterisation and deep expertise of heavy scintillator for high energy physics. The advantage of this collaboration was mainly in the complementary character of the experimental techniques available in the partner laboratories and in the availability of highly experienced scientists indifferent fields. Furthermore close feedback to technological laboratories preparing on request PWO samples appeared extremely helpful. The present paper reports on the most important results obtained during the LUMEN activity in 1996-97. The aim of the report is to provide also enough useful information for the PWO application and novel ideas to stimulate further interest for new detectors as well as application in different fields.
