Hope you got an answer by now but if confused the Mule (no reflector; beam pattern like iPhone "flashlight") and Nichia219 are exclusive to Oveready. I understand that LED is available in other heads besides the mule from OR. They also seemingly have an XPL in cool avail in the larger "turbo" head which uses a Logan sized optic. The XPL is like an XML but used the footprint of an XPG. More lumens but more floody. So Peak terminology is already a nightmare without Oveready making up their own names . The most throw you will get for Eigers is the Ultra (large head) X (10440 only, more lumens than normal) and XPG cool (most efficient tint) with the narrow optic. The Nichia is going to be less lumens than a cool white XPG and comparable to an XPG neutral; at least at normal AAA power. IMHO tho you won't notice the difference between 60ish and 80ish lumens (if it's even that close) so go with your preferred tint. If I had to suggest a combo for anyone it would be the normal head and N219 in the normal driver (AAA or 10440). If it was available in the larger ultra head that would be cool too as I love the look and throw plus it's easier to turn. The N219's tint is almost impossible to not like. Some may prefer a touch cooler or warmer but it's never "offensive" while being efficient and high cri.
