How Compact Fluorescent Bulbs Work

HOW CFL BULBS WORK:

1. An electrical charge is released from the ballast 
2. The cathode releases chemical materials to trigger the electric arc.
3. The electric arc is released and begins to pass between the cathodes.
4. Mercury and other gases inside of the lamp reach an excited state producing radiant energy also known as UV light. 
5. The UV light strikes the inner walls of the lamp which are covered in phosphor, which converts the energy to visible light.
