Triple A (*2) flashlights aren't normally in my wheelhouse, but I do love my BLF-348 which is fairly similar. I was interested to see how I'd like my first penlight!
Here's a 26650 light that's about the most EDC'able 26650 light available. I tested the runtime, and carried it for a while to see how it fared.
After an ongoing discussion here about the smallest 18650 light available, I talked Kathy at GearBest into sending one of those DQG Tiny 18650 lights. At the same time, she included the DQG Fairy. I've reviewed a similar light before - the CooYoo Quantum. These are fun little lights, but let's put it through some paces to see how it looks.
