The led chip seemed super glued onto the board, the +/- are soldered on. I haven't seen reefbreeders' fixture up close so I don't know. I guess if you have a heat gun it's possible to remove it without destroying it. If this is the case I take back what I said. Replacing the whole board is quite the work because you have to take everything apart and put them back. I guess what I am trying to say is that it's disappointing that just because of 1 bad led you have to replace the whole board. This was the one bad led on my fixture.
Ah yeah I can’t guarantee it of course as I didn’t ever replace an led on orphek but plenty of the old value fixtures and they needed plenty of convincing to detach and using a heat gun to melt the connections. I *think* these would be the same and replaceable in the same way. Either way much more do-able than a cluster type setup.
