the inside of my pack is probably pretty dark. I don't fit in it, so I can't be sure, but unless there is a gremlin with a flashlight I keep missing anything that needs light to glow isn't going to be glowing when I need it.
Ahhhh Ironraven. I really look forward to comments like these. They always do to make a person grin.
I can’t fit inside my pack either, and even if I could it would be really hard to carry it that way. It would eliminate the need to carry shelter though.
If this tape is charged, it will glow very bright, even enough to read with if you get it close enough to the paper. During the day, it will collect ambient light and glow very well at night. If stored in a dark pack and taken out in the dark it still has an ever so faint glow. This is better than nothing in a bad situ, and if dropped it still makes stuff much easier to find.
