I published my test of
XPLBWT-00-0000-000BV540E - XP-L2 V5 40E (min. 70 CRI, 4000 K) and
XPLBWT-00-0000-000UU640H - XP-L2 U6 40H (min. 90 CRI, 4000 K)
There are weird differences in performance between both types. In general, in some cases the XP-L2 is not the best choice. The inconsistent color distribution in clear optics is also a problem.
