Hello,
I have the YLP Panda 3R and it is my favorite headlamp although I’m currently picking up some AA headlamps for EDC so one of those may come to replace it.
If I were you, I would get the YLP Panda 3R and a Manker E03h. The Panda for when you need power and/or runtime and the Manker for when you want something lightweight. The Manker takes a AA which can be “borrowed” from all kinds of devices if you forgot to charge your YLP.
As for the runtime claims, I would say it is one of two things. Either it’s a simple typographical error and it should read 2.2 hours or Fenix is taking full advantage of the ANSI Standards for runtime which State that the light only needs to maintain 10% of the max output during the test. Meaning a 1000 lumen turbo can quickly step down to 100 lumens and maintain that for 22 hours. See this post about Maglite using this practice
