I recall reading the DT8 has poor water resistance. That really turned me off from buying one, despite it having some interesting features that appealed to me.

Hanks water rating can and should be taken with a pinch of salt.

My dt8s screws on the bezel were not as tight as they should be and can come loose over time, ideally he should use some low tensile strength loctite and a slightly higher viscosity lube like super lube and ensure the screws are at a reasonable tension.

I do prefer the new screw on bezel for the switch. One of my D4V2s had a visible 1mm gap, fortunately I was able to pop it in the vise and sort it out but shouldn’t have shipped like that.

I personally would never submerge my hanklights in water.

This is valuable info for the community. Thanks for sharing.

Not surprised about the DT8 (though it is disappointing considering the “rating”).

I would’ve thought the D2 would be pretty well sealed though, that’s more surprising.

I actually just discovered this as well with my KR1. I took the pocket clip off of it though, so I’m not sure if that was a factor. It still has a separate o-ring for the tail cap so I wouldn’t have thought so. It was doing a tail stand in my shower when it started acting oddly like you say. Took it apart to find the tail cap had flooded. Still love it, though will be wary from now on.

This is discouraging re: Hanklights. :-(

Meanwhile, my much much cheaper TS10 was actually able to resist immersion for many minutes with absolutely no water ingress nor any ill effects: https://old.reddit.com/r/flashlight/comments/10vm19z/my_wurkkos_ts10_is_now_with_the_fish/
