Coast PX45 Focusing LED Flashlight - it comes with batteries, and can be adjusted from flood to beam/ anything in between.
Real-Kill 20.5 oz. Wasp and Hornet Killer - 25 ft spray, a long distance weapon intended for blinding.
Estwing Sportsman's Axe with 10 in. Leather Grip Handle - highest quality axe they have, and not too long to use as a weapon.
I also considered a combination of like a propane tank, lighter, and fire safe large enough to hide in. Kinda thought that idea was fun, but I had concerns about: a) getting out of the safe afterwards, and b) the fire safe not holding up long enough. Most seem to be rated for like an hour, and the parameters you mentioned weren't specific enough to tell me whether this is a viable strategy.
