And one more thing is subject you are photographing is laying you can of course apply vertical position to fluorescent lamps and/or use some vertical diffusion screen to get wider "reflection stripes".
Closeups on rounder parts like head, eyes, boobs may benefit from arch shaped (good for shoulders area) and ring shaped lamps (you can take pictures trough the ring).
