I used such flashlights, and they often let me down at important moments. I think I should tell everyone that it's no longer worth using standard lanterns that turn on when moisture gets into them. New models of lanterns are always waterproof now. Previously, such water protection could add a few dollars to the cost of a flashlight, but now it's a common thing. So every time I take with me such a waterproof flashlight, https://www.amazon.com/...sories/dp/B089T8HDBV. I took it to the caves a few times. Also, I took it for fishing. Several times, I had to look for weight to weigh the bait on a fishing rod in the lake water with a flashlight. I can claim it works great in water, even if you leave it underwater for 20 minutes.
