ABSTRACT:
Composite base member for operatively retaining a compact, single-ended fluorescent lamp which has an elongated but retroflexed or curved envelope. The base member has a hollow body with a mounting means which divides the hollow body into two sections. A ballast inductor is mounted on one side of the mounting means and a ballast capacitor is mounted on the other side of the mounting means so that the two components are separated, with the ambient atmosphere facilitating ballast component cooling. The mounting means also has the lamp mounted thereon. The composite base member is compact and relatively light and the ballast components operate in series circuit as a lead-type ballast, with the efficiency of operation being good.
