I was disappointed when I lost my SureFire L4 LumaMax while I was moving some items into an outside storage area in early winter, and I gave up hope of ever seeing it again...until today. When I returned to the storage area this spring, there was my L4, frozen in the ice. The flashlight had survived being frozen under snow and ice in -50º C weather in the Canadian arctic, and it worked perfectly when I chiseled it out. When I looked inside of it, it was dry, and the batteries were in great shape. I am now wearing it on my belt again.
