Just got the Frog. Pulled the rest out of the desk.

That’s pretty cool. I rather like the Frog with the extension tube. I have a 10180 light, amazing output really, not so good in the hand though, a bit too short. But can work on a set of keys.
I have 2 - Lumintop GT Nano and Sofirn SC01. The GT Nano is nice though not great utility as a tiny, tiny thrower. The SC01 is a great key chain light with 2 settings, 10 lumens and 330 lumens of SST20 4000k 95CRI light.
Maybe look at Folomov C2 next? About Frog-sized,but much bigger battery.
