Default "correct" HID bulb for plant growth?

I have been wondering about the lighting issue for sometime now, and what I have been wondering is : If I go to Home Depot and purchase a 400W HID fixture, and one 400W HID bulbs (for around $25). Will this be the "correct" HID bulb for plant growth? Or is this bulb only suitable for illuminating parking lots? The same question posed except for hps lights.
Thanks a few hundred (Inflation, you know!)

Hi jeff
Just make sure it says metal halide and not mercury vapor or some other kind. Just because it gives off light doesn't mean that it has the right light spectrum for plants.
