wiring for florescent fixture

I have to change out a 4 florescent fixture and install a new one. There are 2 red and 2 black wires coming from my ceiling and only a white, a black and a green wire in the fixture. I am absolutely clueless as what to do without burning the house down
Any help would be appreciated
thank you

Are you sure there aren't any more wires ? There should be white wires present.

What colors are connected to what now ?

There are 2 red from the ceiling that are twisted together and 2 black that are twisted together. When I took out the old balast there were 4 wires coming from each end of the balast box. I went to the hardware store to buy another balast but none had 4 wires from each side coming from the balast so I bought a whole new fixture not realizing it only had but the black, white and green wires.

I am adding this - it is 2 greyish green wires, not black, sorry
No whites

As Pete asked, how were they connected on the old fixture? There must be a white set of wires somewhere in the mix. Can you take a picture of the ceiling box with the wires pulled down so we can see them? http://www.doityourself.com/forum/el...your-post.html

Do you have a volt meter?measure voltage between red and grey you should get 120 volts with the switch on, I would say that the black from the ballast goes to red and white from the ballast goes to the grayish color conductors.

Gray is an alternate color for neutral when the system is wired in conduit.
