I know in another post I said that you didn't need to use the nicer heat sinks (at least with Bridgelux strips) like the build sheet suggests. The Bridgelux build is 15 strips vs the proposed Samsung build you are looking at that uses 5 strips, both running the same amount of juice. That would suggest to me that those Samsung strips will probably get hotter and I'd definitely want to make sure I had the nicer heat sinks. They look sexy too, which is a bonus.
