Well, the T10 is a small OP light. Here: https://budgetlightforum.com/t/-/10972, post #3, Match measured throw at 1136 (1.1 kcd), so maybe the XP-L improved on that. Match measured throw with an Eneloop. My Enelopp Pro's won't fit this light - too wide. I thought the hot spot was definitely tighter before - sorry, really didn't pay much attention to the T10's throw. In theory, the XP-L is the dye size of an XML, so it shouldn't throw well.
