Welcome to BLF

I don’t have either of those lights you mention but do know some threads about small lights that might interest you

List of 18350 flashlights (currently available)

After "reconnecting" with my DQG Tiny 18650 (1st version) last night, and marveling that it's still one of the smallest 18650 flashlights ever made, I began thinking about smaller lights and that I've recently noticed a few more entrants in the 18350 format. Thinking about the latest higher capacity cells such as the Vapcell 1100 (Aspire) I began a search to see how many 18350 lights I could find, and decided to make a thread listing currently available models priced under $100. I'm not listing…

Smallest 18350 light?

Dec 2021 bump - have any new (small) 18350 lights been released? Super small 16340-based lights like the Olight S-mini or new Klarus Mi1C are nice to have sometimes. But the (edit: no longer new) Aspire 1100mAh 18350 really makes me want an 18350 mini-light, to take advantage of the Aspire battery’s excellent capacity and high-drain capability. Yes, I’m aware you can put an 18350 tube on an S2 or a D4, but those lights still aren’t designed around being the smallest light possible. Options me…
