Abstract: A modular ballast system particularly suited for strip lighting installations has ballast modules on opposite ends of each fluorescent lamp tube, each module having lamp connectors for receiving the end pins of the fluorescent lamp, capacitance and inductance elements connected to the lamp connectors in each module, and jumper conductors interconnecting the capacitance and inductance elements of the modules to define a bridge type ballast circuit for powering the fluorescent lamp. Each ballast module can be made small and lightweight with a single inductor and capacitor forming two legs of a four leg bridge type ballast. Pairs of ballast modules can be connected back-to-back to transmit electrical power without external wiring to successive fluorescent lamps along the strip.
