In Pennsylvania, only employers of seasonal farmworkers are required to provide breaks. These employers must give employees a 30-minute break after five hours of work, during which employees must be relieved of all duties. This time may be unpaid. All other Pennsylvania employers have no obligation to provide either meal or rest breaks.
Overview. 1  A cold cathode fluorescent lamp (CCFL) is a lighting system that uses two phenomena: electron discharge and fluorescence. CCFLs are mainly used as light sources for backlights, because they are smaller and have longer lifetimes than ordinary fluorescent lamps.
In this mode, the voltage present across the lamp's terminals may be anywhere between 70-300V, depending on the lamp and application. A similar ballast is used for CCFL lighting found in LCD panel backlights (laptops, camcorders, digital cameras, and what have you) and some newer CCFL flashlights.
