This project needs a little bit more know how than the average small electrical job. You need to consider total loading and thermal effects of fitting recessed lights. I would suggest that you get a qualified spark for advice or purchase a d.i.y book. I have come across many downlight "have a go" disasters that could have been avoided. Don't be discouraged, with a little knowledge it is possable. Hope this helps
