Stupid question, metal lamp shades?

Hi guys, ive seen these aluminium lamp shades used on CFLs but I cant find them ANYWHERE in the uk. Anyone find me a link?

Cheers,
Tom

they are reflector clamp fixtures:

^^ this one is expensive to me...they are only about $6-8USD here for the cheap ones...

You can get them from pet stores, hardware stores, etc...lots of places have them

That is pricey! as i'll need 3 or 4 of them!

I'll browse around on some petshop sites, thanks
