The necessity of clean energy resources development has increasingly become the focus of attention of
the world. An important contribution to this topic could be given by minor waste in the illumination system.
This paper presents results obtained by qualification tests implemented on electronic ballasts, with
particular attention to on/off, thermal tests and EMC tests. Being the device under test an innovative electronic
power supply system designed for application in energy saving, it is fundamental also an evaluation
and analysis of the reliability performances. To this aim some results obtained with reliability
prediction method are also presented in the paper.
