HPS = high pressure sodium, it gives off a red spectrum imitates the sunrise/set during fall/winter. Use for flowering.
MH = Metal Halide, this gives off a blue spectrum imitates daylight. Use for vegetative growth.
Flourescents gives off blue spectrum that is why some people use this for vegetation.
And no they don't have a ballast at the base its just a simple socket, and the bulb is a tube with gas inside and when given power those gases light up.
