I was reading the thread on flashlights exploding from accumulated hydrogen gas. While I imagine having a truly air-tight light takes some rather deliberate designing, I wonder if making a "well-sealed" light could present similar problems? I don't want to give anyone an exploding flashlight. Lol, it's bad enough that the battery chamber is going to look like a 7-shooter. /ubbthreads/images/graemlins/smile.gif
So, I was trying to think of a simple and inexpensive way to provide for some gas exchange without making the light overly-vulnerable to water intrusion.
Now, if you take apart a simple stick-pen you'll notice near the end of the plastic ink-tube there is a little something stuck near the end of the tube. I figure it must be gas-permeable to prevent a vacuum from forming which would make the ink stop flowing, but maybe would stop liquid well enough. I'm thinking having one of these press-fit into a small orifice in the light body might be just the trick, perhaps with a stepped hole that would be very tiny on the outside.
