Also for reference, the previous gen TD16 with XM-L2: https://budgetlightforum.com/t/-/21057
1,000 lumen measured, barely above 24k CD.
From what I’ve seen so far, the XP-L HI is short of doubling the CD, so 50k CD as advertised sounds optimistic, though still reasonable, but 70k is too much of a stretch.
Another reference, the Eagletac S200C2 with XPL-HI V3, 47mm head, 961 lumen OTF, 58,400 CD advertised.
