Good looking shot!
For the flourescent light fixture i would suggest using a simulated "area light", a light that is constrained to traverse a spline that approximates the area of the light in a multi pass render.
I don't think it will be any more time consuming than the bulbs, maybe much less so if you use shadow mapped klieg lights (set very wide) and it's easy to scale downh the effect for quick tests by setting the multi pass number to a low value.
