Horizontal bars

[gilleklabin]

Hi RedUsers

I'm once again struggling to find the answer to this on the red forum so i'm posting out of necessity.

I just shot a little interview piece and used mainly strip lights with fluorescent bulbs to light the room, as i play the footage these weird darker horizontal bars appear on the screen. it's ruined all my footage. Any advise as to what ive done wrong, or is this a case of taking my camera into RED?

Thanks in advance
