Frozen flashlight and then turn ON to melt torture test

Which flashlights are tanks? This Fenix PD35 v3.0 is one I keep attached to the gutter and is 24/7 out in the elements to see how long it can last OUTSIDE.

As a side test, I froze the Fenix PD35 in a cup and kept it frozen for a week. I then took it outside of the freezer, turned it on Turbo mode (1700 lumens) and allowed the heat to melt away the ice. It did turn on after frozen for a week, and handled the melting like a pro. Any other suggestions on torture tests for the Fenix?
