High Pressure Sodium Lighting Question

Okay, well, I have these 100 watt HPS sylvania medium base lights. I have my lights set up with just typical CFL socket lighting. I found these 5 Leviton Mogul Porcelain HID Lampholders High Pressure Sodium Light Socket's on http://www.fruitridgetools.com/storefrontprofiles/processfeed.aspx?sfid=136763&i=164153606&mpid=8171&dfid=1 <--------- That site.

I was wondering if those would work on hooking up my HPS lights into my homemade reflector that is already pre wired and running. The only thing that I was wondering is if I'm going to need a balast also to make them run correctly.

I run 4 150 watt hps lights instead of 1 400 watt it distributes light without light and heat all being in 1 spot to answer your question I have a ballast for each light.

you need a ballast for these so if you dont have a ballast its no good.

if you dont have a balast to run it then hid bulbs are just glass.....they sell 100watt hps lamps simple as fuck at home depot or lowes. 60 or 70 bucks for a 100 hps. i have 3 to supplement my 400 and 600 hps lamps.

Okay.. I'm still a little confused.. I have 4 100 HPS bulbs.. I found those sockets and I'm wondering if they would work or if I am gonna need to get a a balast for each one or if I'm gonna be able to just use those sockets.... or if I can possibly just get 2 200 watt balast since there are two bulbs in each of my reflectors.. I'm new to all of this HID system shit and I'm just trying to go the cheapest and most efficient route.. If anyone can give me a better answer on where I can find these and how much it is gonna cost me I would really appreciate it.
