Myself I do not see any problem using lithiums in a regular mimimag, those bulbs are more foregiving in current and voltage than a LED version, besides lithiums have advantages that I know of here in Alaska, we use them all the time in the winter when its as cold or colder than minus 40°F.
Also is the ability to store it for years even, case in point is that many trappers way up north in the Alaskan bush (thats parts of the state WAY far from civilization)have what is called "caches", these are little mini-cabins built on poles up in the air away from bears and wolves to store furs, emergency fuel, food,clothing. So lithiums are definately a plus in that environment.
