I got it with the 21700, and I also bought a Vapcell m11 18350. I was looking for a small and very bright light, and that’s what I got!

This small thing has no problem lighting up the entire street. It’s like having car headlights in the palm of your hand.

With the 21700, the battery life is very good, and with the 18350, it’s a quarter of that, at 30 minutes on high (2000lm for 5 minutes then 1300lm) and 1h30 on medium (550lm). The light output appears to be the same with either battery, at least when fully charged. With the 18350, the light does dim at around 30% of battery.

I 3D printed caps for the 21700 tube so that I can store the 21700 battery inside its tube. It also works with the 18350 in its tube when I use the 21700.

The beam and tint are not too bad for me, it’s mostly white except for a greenish donut, but it’s uniform, so unless you are lighting white wall it’s not noticeable. Now it does have a low CRI, but that’s fine because it’s so bright!

But I may have to get another light for CRI… maybe a D4K MAO or an Anodized Ti Midnight Echo Mini Pineapple or a Maeerxu XT3 Anodized Sandblasted Ti… So many options!

Thank you all for your help in choosing a light.
