"This paper aims to assess and compare lifetimes and parameters of light sources, as they are presented in the professional literature and also by the producers. These values often don't match and there are some values, especially those presented by producers, which are rather theoretical and they haven't been yet practically verified. Within the research in this area we intend to realize several experiments, which should provide further knowledge about light sources lifetime from different perspectives. Another important factor, which may be related also to lifetime, is a modification of light quantity parameters during the indicated lifetime of light sources and also the influences, that affect these parameters. With this phenomenon, we want to deal in the paper too. We assume, that the paper will be mostly the literature search of yet published information with a view to suggest other ways of research, that should be made shortly." . "2010-06-23+02:00"^^ .
