Normal Ballast Factor

PROStart T5HO ballasts operate from 120V through 277V, 50/60 Hz, eliminating “wrong voltage” wiring errors and reducing the number of models in inventory by half. PROStart ballasts provide optimum starting conditions to provide up to 100,000 switching cycles for use on occupancy sensors and building control systems.
