Bottom side of Ledil square lense with sticky stuff. Made to fit right over the skinny side of the Cree emitter. This bottom surface required some alteration to fit over the solder and wire on the face of the star.

Bottom side of star inserted into bottom of optic. (Left the sticky backing on for fitting purposes). In fact, I glued the stars on like this so that they would be centered in the sections of the housing.
I filed the bottom of the star to make sure it was flat since it is a stamped piece of aluminum. You want it to mate nicely with the mounting surface for maximum heat transfer.

Getting ready to fasten the stars with Arctic Alumina Adhesive. AAA provides, adhesion and good thermal conductivity while not being electrically conductive (or capacitive). Use a very thin layer.

They're on now! I can still pull the lenses off... in fact I still have to drill holes for the wires and solder them to the stars. I marked the bottom side of the lenses because they have to fasten over the Cree in a certain way.

Stars in tact. Middle one looks crooked, but it seems to fit together well this way!

Close up. It might be better to apply the layer of AAA to the back of the stars, but I just spread it across the mounting surface. I probably used more than I should have. A thin layer is best.
