Appreciate that.

That is what I was wanting to look for - to see if any gaps became apparent. 
I guess it wouldn't as otherwise it would become obvious to normal eyesight, 
and fluorescents do get used for movie filming (saw an advert done this way, 
and the film crew changed all the fluorescent tubes for ones they brought 
with them.

>but it's quite acceptable to most people.

agreed.
