Yeah that's fine mate SMD is a great LED, only thing I will say buy cheap buy twice, 50W LED flood with PIR for that price I can't see it lasting a great while but never know, if it does go faulty then it will most likely be the PIR as its not often LED goes, I sell them at work which come with a few year gaurentee but are over double what that price is but worth giving it a try, what wattage was your previous halogen fitting because 50W may be a bit too bright depending how high u put it & the area it's covering
