Hi bigC,
there are some "versions" out of direct coper bonding. If you takle a look at saablusters deft-x :

you can see a copper star (seems to be a sinkpad) on a heatsink (probably also copper). he talks here from direct copper bonding. this is true, no question. but you can also solder a led direct to the big copper heatsink (the heatsink must have a pedestal). this will be the better version in my opinion, cause you don´t have the transision from the star to the heatsink. but this is really hard to realize, cause the centering from the led is essential.
so, from my side there are no questions about direct copper bonding. this is an absolute MUST DO for all my Black Bullets and my Black Bullet X. Without this it is not possible to overdrive the LED to such high levels with continuous Lux output.
