The fluorescent lamps has a ballast placed in series with a load to limit the current in a electrical circuit. Thats limit the amount of current passing thru the fluosrecent lamp.  It is used to start providing the high voltage to the lamp and them limiting the amount of current .  These electronic ballast are used in series with compact fluorescent lamps (CFLs) and High Intensity discharge lamps (HID lamps).     

5 symptoms of a bad fluorescent ballast:
- Flickering
- Buzzing
- Delayed Start
- Low Output
- Inconsistent lighting levels

In general, Ballast can be classified as PCB (Polychlorinated biphenyls) and "no-PCB".

PCB enclosure can leak if damaged. Coming in contact with PCBs does not mean you will get sick or have health problems. Getting sick from being exposed to PCBs depends on the amount of PCBs that entered your body, how long you were exposed to PCBs, and how sensitive your body is to PCBs. (idph.state.il.us)

Why You Should Recycle them?

 Recycling the PCB and no-PCB ballast will help the environment, land and soil, and human beings because would not eat contaminated fish, meat or any food been exposed to PCB.

Why is so important to Recycle PCB and no-PCB's Ballast?

  Can not be ​thrown into the land fields, toxic elements will affect water, soil, human beings and animals.

 ​ Local and Federal regulations requirements.  ​Businesses are reliably responsible for their waste even after disposal.

 ​To protect the environment and health, because of the toxic elements contained.
