Looks nice.

As the lamps are visible in the scene itself, you need them. As there 
are many of them, you can probably use regular point lights, at least 
for most.
Keep those simple.

How large will it be in the final scene? How visible will it be?
It's possible that a largely simplified version would be OK.
As it is now, it use media, complexe geometry, transparency, and maybe 
photons.
Some simplifications:
The center part could be replaced by a simple lathe or sor object with 
two spiral patterns, one scaled <-1,1,1>, white with high ambient and 
transparent.
If you still use media, only use emissive inside the core.

In that one, adding a few faint lights could improve things.

The judicious use of spotlight or light_group can possibly improve 
performance.
