Get something so it can be turned on. I believe they're called ballasts.

While you're at it, you'll want a reflector as well, and, perhaps, a cool tube.
 
So your saying you have the bulb and thats it?

If you you will need something for your bulb to screw into and a ballast to run the bulb.

Do a quick google search for 400w HPS system. It will show you everything you need.

Doing a quick google search is your best friend when it come to grow questions
 
Not trying to be a jerk but you need to do some searching your self. People on this site cant do everything for you. That last link I found with those prices took me less then a minute to find.

I will say it again. Google is your best friend
