okay so i got a new 600W assembly (ballast, socket, bulb, etc..)
and i hooked it all up and it does not work...wtf i connected the ground, black and white wires to the socket (white on sliver screw black on gold) and i put the bulb in Tightened it appropriately, connected the wire to the ballast, plugged the thing in and no light! the ballast is buzzing so im guessing its working, since i bought 2 setups like this i tried using the other bulb, ballast and socket NO luck, i switched around the wiring still no luck! any one no what the problem is !!!!!

You can hear it buzzing. How long did you wait. HPS take a minute to warm up.

i waited like 10-15mins does it take longer?
