I was thinking about the low pressure water resistance tests which some people perform. This usually entails a sink, bathtub, and occasionally the deep end of a pool. This is all fine and dandy for most uses, but what about the more robust lights which should be able to handle much, much more?
So, I thought of a more extreme water resistance pressure test. But first, there is just one point I need to make clear:
**WARNING, DO NOT ATTEMPT THIS AT HOME**
Okay, now with that out of the way, this is how you attempt it at home.... :devil:
Take your average 2 liter soda bottle (preferably clear) and remove the wrapper. Turn on your light, drop it in, drop in a handful of dry ice chunks, fill it about half way full with FILTERED water (very important it's filtered), and quickly and cap it off. Set in a safe place where the impending will be safely contained.
Now, what good is this other than being extremely entertaining??
Well, as most people know, putting dry ice (frozen CO2) and water in an enclose container builds up pressure and explodes. In your typical 2 liter soda bottle, the minimum rated burst pressure is 150psi. So even though you only put a few inches of water in it, the increased pressure mimics deeper depths. Just how deep? Well, 150 psi is equivalant to 312 feet deep in salt water or 346 feet in fresh water.
Why filtered water? Well, if the light does leak, that doesn't mean it's doomed to die. Contrary to popular belief, water doesn't fry electronics, it's the minerals dissolved in water which make it dangerous to electronics. If the light does leak, you simply have to dry it out and it should work again. Filtered water minimizes the risks of permanent damage.
Couple key notes:
1) Keep in mind that the light may go flying. Might want to tie an orange lanyard onto it.
2) This is extremely dangerous and loud, plan accordingly.
3) Not responsible for any permanently damaged lights.
