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.
The correlated color temperature (CCT) designation for a light source gives a good indication of the lamp's general appearance, but does not give information on its specific spectral power distribution. Therefore, two lamps may appear to be the same color, but their effects on object colors can be quite different.
