Abstract
A low component count and lightweight ballast usable with fluorescent lamp loads of widely different wattage has first and second inductors and first and second capacitors connected in a bridge circuit and can provide current regulation within a few percent for lamp loads between 14 Watt and at least 40 Watt. The two inductors can be wound on a single toroidal core for maximum compactness.
