Can somebody please answer the following questions? I am having trouble understanding what equipment you need when it comes to HID's.

1. What does ballast have to do with lights?
2. How do you know what ballast to use with what light (HPS/MH)?
3. Where can you learn more about ballsts and lights?

Thanks for the help in advance!
