If i check the SSt-40 test from Djozz Luminus SST-40, a N4 BA bin tested we can expect something arround 2200 lumen 7A.
I can not say what the final numbers are. When they tested they eliminated some resistance in comparison to a assembled light (no switch, no springs and no electrical contact points like tube to tailcap. . . .)
Also i have no idea about flux bin of the 5700K SST-40. They are relativly new. Until now you only could get the colder 6500K and above.
