I recently got the ThruNite T10 II and I love it. I got the CW version but I see they are sold as NW as well.
Ticks all your boxes and for $20 you can’t go wrong.
My other preferred small lights are:
Klarus Mi7 - decent power but I don’t like the UI so much.
Klarus XT1A - amazing light but too large for 14500.
Also none of them has NW afaik.
Get an S2+ with a shorty tube. Infinitely moddable, can be fitted with a TIR lens (flood to spot, your choice), ask Simon when ordering and he can pretty much make it to order (LED, driver, UI).
Hint: The generic XM-L2 in 4C tint behind a TIR lens is quite nice, “warm sunlight” I keep calling it. And the new colors as well as the old standbys (teal/violet/orange/red/green/blue) all have shorty-tubes as well.
Sofirn SP40. It’s a 18650 flashlight but comes with the 18350 tube right in the box. It fits all of your requirements and you will get a really versatile flashlight for many different uses.
Well, other than the fact that it doesn’t meet many of your criteria, the ON THE ROAD i3 Mini Zoom looks intriguing. Does anyone have either the i3 or u16?
