Examination of T8-T5 Electronic Ballast Adaptor

This paper presented an examination of conversion from T8 conventional fluorescent lamp into a T5 lamp with electronic ballast. Without changing the T8 fixture, a T5 fluorescent lamp can be fitted into the fixture with a T8-T5 electronic ballast adaptor, which provides both power factor correction (PFC) and high frequency switching. The power factor of the overall lighting system was regulated to be 0.98, and the electrical efficiency was 95%. All these features cannot be achieved with the conventional magnetic ballasts.
