What is PROGRAMMED START?
A fluorescent lamp-ballast circuit that uses a custom integrated circuit (IC), which monitors lamp and ballast conditions to ensure optimal system lighting performance.
PS ballasts heat the lamp cathodes to 700 degree Celsius prior to lamp ignition.
This puts the least amount of stress on the lamp electrodes, resulting in maximum lamp life regardless of the number of lamp starts.
Programmed-start ballasts are typically wired in series.
