Excellent magnets.....highly recommended.
Used two magnets recessed into a wooden base to hold a 10W LED. Recessed magnets flush with wood, mounted LED bracket, araldite/glued magnets and nuts into place and then covered with rubber. Wired 4 LED lights in a row, attached to outside of 4X4 ( rubber base leaves zero scratches :) ) and connected to battery inside battery box. BRILLIANT and holds very nicely indeed. I also used 2 magnets on the back of my miners pick for when I go metal detecting....pick up crap magnetic targets on the pick to save time digging. Love neodymium magnets....1000 uses indeed :)
