I guess the take away here is the 4000K bin is better than any “D” version 4000K bin i’ve seen. I would rate it as good for “dome on” even though it’s slightly above BBL. Considering the current state of the “green LED” epidemic I would say the others (minus the crappy bin 5K) would still rank average against most commercial LEDs and would probably all be exceptional shaved, as most of the “D” versions have been.
None of them are the next amazing LED but considering the price they probably have a use somewhere, especially if you shave them.
