For a recent tender we were asked about the sub zero capability of Wolf Eyes torches. We know are torches are very capable in sub zero conditions having been used by many specialist units in the Australian Alpine region and overseas. We wanted to show the batteries and torches capabilities in cold temperatures, so decided to photograph one of our torches in an ice cube. The process was to turn the torch on low, then place it turned on in a freezer for 4 days till the water became an ice cube. The torch was going the whole time! We then removed the ice cube and photographed it. This is possible due to the rechargeable Lithium Ion battery technology used in Wolf Eyes torches.
Some other photos from when the cube was starting to melt:
