I am currently modding my 2 SF U2 clones from Kai to accept:
- 7xRebel100 and flower holder and
- mr11 4x cree holder from cutter => I just finished this mod, see post 4 for description and pictures
Both version should be able to push around 1000 lumen powered by a shark. Of course this could be regulated down in cases longer runtime would be needed. But I am more into “bright as possible” lights as I don’t use them for a long time continuously.
The only thing I am missing now is the heatsink.
The easiest way would be to use pieces of aluminum or copper with the dimension of 1cm in height and 2 respective 3cm in diameter.
Does anybody know where I can get these from?
