Combine lighting spurs or new CU?

I know, we'll have an inspection table but generally want the light to be as good as it can be, without getting specialist.

I meant a specialist to advise you on the lighting, not (necessarily) specialist lighting.

Dagoof,
If high value printing then a specialist lighting advisor is a good idea.
If on tight budget, then this is a good American article that might help you in sourcing and purchasing the correct tubes.

The following article has links to suppliers at the end:

and (I think) here are more tubes that that article is referencing:
