Well I can't answer if they'll work underwater -
but I can tell you that my Dim 20 for $20 LED from CountyComm (using a single 2016 battery) managed to survive TWO full wash cycles in my washing machine.........
Yes, TWO full cycles - both with 2nd rinse and spin.
Why did I use such a severe torture test?
- well DoH! /ubbthreads/images/graemlins/blush.gif it was an accident -
I managed to leave my dim 20 for $20 in my pants pocket when I washed it - and didn't notice/find the light until after I completed the next/another wash load - so 2 full cycles - both with 2nd rinse and spin.
When I saw the light at the bottom of the machine when I was unloading the second wash - I pull it out and switched it ON
and it worked!
So I opened it up to dry things out (so, yes, it was wet inside) - and took the opportunity to take a photo/scan -
along with the left-over materials I used to make the dummy battery cell so the light would work with a single 2016 (to salvage the strobing/bad LED and give a dim white light)
that's a less successful plastic disc I tried cutting by drawing an outline of the 2016 battery - I found it much easier and more successful simply cutting directly around the 2016 as the template.
The dummy battery is using 3 layers of these home made platic discs wrapped with aluminum foil - emphasising coverage around the edge that faces the contact/"switch" area.
