noob lighting question

im thinking of doing a vertical light grow and purchasing these ballasts....and i wont need any hoods.

my question is what else do i need assuming i have the ballasts & bulbs do they sell like a socket for the hps bulb or something or would that come with the ballasts?

if it dosnt come with the ballast your local grow store should sell a knuckle for the bulb
