ok i just solve my centering and fixing problems

now is my only question about the conductivity of the ground
ther are three metal covered areas

The large center area on the underside of the CREE is the thermal path for heatsinking the LED The other two areas are the anode and cathode of the LED. You must either sever those connections to the bottom of the LED, or insulate them. Snipping off the four corners of the LED will work. Or, you can use a Dremel tool and grind off the connection points. You can see them if you look at the four corners. (It is a small dot in the corners.)

When you get the LED's prepared, test them with a multi-meter to ensure that you have actually severed the connections.
