How can I power this?
I have a 2' 2 light fluorescent commercial light that has one black and one white wire coming out of tha ballast, how can I power it? I would like to have it plug into a wal outlet if possible, thanks : )

Simplest thing is to buy a 14ga extension cord long enough to reach your receptical (a decent "shop" cord not a lamp cord). Cut the female end off and discard, then strip the wires back. Remove the knockout in the light fixture and insert the appropriate cable clamp (commonly called romex connecter), then, using wire nuts, connect white/white, black/black, green to grounding screw on fixture . Support the cord with a few staples, and plug in.

ohh yeah one more thing, what is the grounding screw in the fixture?

Check the ballast for voltage. If it is a commercial fixture it could be a 277 or 347 volt fixture.

its 120V - 60 Hz

also there are three wires in the extension cord i purchased, the middle wire is greena dn the other two are not colored... what do i do? and is there an alternative to wire connectors because my store was out of them : (

Use a meter to find which wire is connected to the narrow spade. The narrow spade is the hot wire.

yeah i found out which was hot and nuetral i jsut need to know if there is a special spot on the fixture or it can go in this spot which looks like the only possible spot for a screw? thanks for all your help guys : )

The ground would be the metal chassis of the fixture. If no green screw on it, pick anyplace that would allow you to attach a lug or spade which is crimped to the ground wire on the cord.
