Abstract
The present invention provides a base socket that fits into incandescent fixtures and allows one or many 'stick' type compact fluorescent lamps to be inserted. The fixture allows the user to insert as many CFL's as desired without changing or rearranging, in any way, the ballast. The ballast circuitry is designed for series or parallel electrical connections of the CFL's. When in series each socket has a bypassing microswitch that provides for electrical circuit continuity.
