Do we know how hard they can really be driven? Zebralight won't drive them hard of course, but they don't drive anything else hard either.
Djozz tested some that Simon sent him on BLF and they permanently failed above 3A. Mcbob said the same thing in the comments in regards to his own testing and said he doesn't think they should be driven above 2.5A.

Above 2.5A CRI drops under 90, Duv and CCT go way up.
