"Don't get me wrong - they are cheap to buy - but they are cheaply made. There is very little metal at all - even the reflector is painted plastic. I have just installed 9 of these today.WHEN THEY ARE UP, THEY LOOK FINE, but I will be interested in seeing how long they will last. If I was fitting them in my own shop, I would be slightly concerned as to how long they will last. They are also very slim (which is why I chose them). If any fail, I will update the review."
