LED star base heat sinking?

Folks, To make a decent bright bicycle rear light I'd have to ideally remove a 1W LED from it's aluminum star base. If they are heatsinked like in this video it looks like some thermal grease is used: Not sure if that's the normal method with these small LEDs. I am concerned that such thermal grease will work itself out of there. This is for my mountain bike which is used on rough turf. Is there any other glue that can be used? I'd like to glue or somehow otherwise mount the LED to a home-made copper carrier which much better fits the innards of a retrofitted old style bike light (one where the bulb is removed). "Modern" lights that already have LEDs are mechanically too flimsy, too dim, or both. The LED is going to be operated at about 50% of rated power but then often for 4-5h. -- Regards, Joerg
