    Hi everyone, I want to know if anyone has tried brazing leds to a heatsink?
    I want to try to cast my own heatsink with the lost-wax method and machine it flat, and then permanently attach led stars for best conductivity.
    If one blows I will simply detach the led from the star base.

    When those stars are exposed to salt and salt water moisture for long enough, the black covering with the contact points for the led starts to peel off. I would not fix them in place permanently.

    I think the heat of the brazing will destroy the LED. While soldering, you do not want a red hot solder iron either to overheat the LED.
