At least there do seem to be more people jumping on with them so there should be more anecdotal evidence from actual independent sources eventually.

The cost has come down a huge amount compared to the early generations of LED's, so this is a positive step, to me though I still see them as an uneconomical option for larger tanks. There's a way to go in this regard still.
