Direct bonding to copper: p60 triple nichia build + p60 XML build

Just got back from class and looks like you guys had some good discussion going on haha. Ideally I wanted to start this build ASAP but will probably have to wait til may to start.

Yea, the idea is to raise the LED so I still have access to the bottom contacts. I’ll use a method mentioned in OLs thread about making stars to gain access to the contacts with copper pads.

Let me know how the turning down the 20mm star goes. Sounds like it could work out. I only worry about the +/- contacts making contact with the pill if I were to install it in the p60 drop in. Is it possible to grind off part of the outside of the contact so that it stays fairly physically isolated? Hold on to your sinkpads for now as you will probably have better use for it. Ideally I wanted to start this build ASAP but will probably have to wait til may to start and the 16mm sinkpads might be out by then.

I mainly want to make these builds because there isn’t a drop in currently that fits what I want.
For the XML I want:

- XML-2 T6 3C

- Direct copper bonding (reduce thermal sag)

  • Some extra mass/better heatsinking (reduce thermal sag)

For the triple:

- 3x nichia219

- triple driven with 1 amp to each led

- direct copper bond

  • DrJones Lupodrv driver
