These lights are just as bright as the LED fan lights - the actual fan, I would just buy a few fan's and remove the actaul LED's this way you got a working fan with no LED's - I'm not too sure how hard the LED's are too remove though, and as far as "I only need afew" well one 80MM fan contains around 4LED's so 4LED's are bright'ish.
Hope this helps.
