Abstract
A lighting system using a PL fluorescent lamp which is capable of screwing into a standard electrical lamp socket utilizing a base member possessing a mechanism for mechanically supporting a PL fluorescent lamp. A male fitting is connected to the base member and includes an outer surface which may be threaded in configuration. An adaptor is also used in the present system and is capable of mechanically and electrically connecting to a standard Edison electrical lamp socket. The adaptor includes an external threaded outer surface for threadingly engaging the standard Edison lamp socket, and also includes an inner surface in the form of a lamp socket. The inner surface lamp socket of the adaptor is capable of mechanically and electrically contacting the outer surface of the male fitting. The adaptor inner lamp socket and male fitting are of a non-standard size. The adaptor locks into the standard Edison electrical lamp socket, preventing its usage by standard incandescent lamp bases.
