No problem mate, yeah it's exactly the same. I'm not sure if I kept the spare acrylic 'cradle' that I screwed to the fixing and slot the lights into, I'll have a look tonight, if not I can easily make you another next week or you can find your own way of fixing them in there, it depends what lights you get I suppose. You'll need the cables and fixings to hang it up and that should be all.
Maybe someone with two grobeams can advise you better about what you need, someone had two of those aquabars on here (can't remember who) and they looked pretty good and better value for money.
