How to render office lights?

[Richard7666]

I'm trying to achieve something like this.


I'd like to get the nice falloff. I've tried the "brute force" method of putting a VrayLightMaterial on some cylinders and a refractive material for the frosted plastic cover, but render times are far too high

Any ideas?
