Freezing my lights...

[IcantC]

So I got bored and decided to test the waterproofness and cold performance of my lights.

I used 2 lights
1) Jetbeam C-LE V2(clicky)
2) Fenix E0
I wanted to try the A2, but didn't have spare CRs on me(just ordered some with lighthound).

I took a Gatorade bottle for each, filled it with water, turned the light on low and dropped it in. Closed the lid and left in the freezer for 3 hours.

After 3 hours, both were frozen solid in ice with the light still on and functioning. I should have let them sit for perhaps a few more hours to extend the test.

I melted the ice by running hot water on the bottles and took the lights out. Both were dry on the inside and were still running.

Not really sure what I accomplished or hoped to accomplish haha.

I would leave them for a few days, but then the batteries will run out on low :-/.

Cool.

That certainly does sound like an interesting test. :thumbsup:


A much better "torture test" than simply
dunking it in a water glass at room temperature.


And a Great Idea doing this with the light turned ON !

Very cool. I wonder what would malfunction first, the led bulb or the li ion batteries that freeze at -40 C if you were to do a freeze test.

Thanks, I wanted to try with the Incans to see what would happen. Sadly the only Incans I have do not have long enough runtime to be frozen and still be running. Perhaps I will freeze water in the bottle, break it and then throw in the Incan.

Only incans I have that might fit are the A2 and Z2.

Oh as for betteries, I used an Eneloop in the Jetbeam and the E0 had a E2 lithium, BUT I replaced with some cheapie AAA for the test.

You accomplished something, a real-world torture test for these two popular lights. I'm sure there are some lesser lights that would have failed. Anyone want to try the hose test next.

Here are two pictures of my HDS frozen in solid ice. It was in the HDS section before the section was removed.

This was done last winter when it was -20 outside. I left the light on the 10lm setting in a margarine container and left it outside for over 24 hours.
