Lights?

So i was in Lowes today pricing out the stuff im getting for my stealth grow box, and i came across the lighting section. im most likely gonna be using CLF's because i need to be discrete as possible, but i saw Lowes carried 400w Metal Halide , 400w High Pressure Sodium bulbs with a mogual base. I was wondering if anyone on here has used these bulbs from lowes in their grow? and if they are any good or not? Also if you used a ballast or not for them?

If you use one of those bulbs you're still going to need something to screw it into and a ballast. It will also run a lot hotter which means you need to worry about ventilation.
