that looks spot on from the one i got today in the post.
Mine too, was from spain, maybe they make the best ballast's eh?
Anyways, your wiring looks sound, exactly like mine, except for the fact, my light didnt have an earth.
Ballast did, but my light didnt.
I would say, its wired up EXACTLY the same as mine, I too contacted a sparky, and he confirmed my setup before I switched it on.
Mine works perrrrrrrfect.
