First of all, just based on looks, this is some serious James Bond lookin design. Yes, thank you very much Q, I'll take 5...

"Lumen has relatively simple work principle - you touch TEG (Thermoelectric Generator) - small ceramic bar that can produce electric current when we provide temperature difference between upper and lower parts of TEG."

"How to help you to find it in a complete darkness? You can order Lumen with tritium vial - glass tube with a phosphor layer in them and tritium gas inside the tube. This tiny vial will produce light for over a decade. "-source

So as long as ya don't go corpse-cold (in which case you've got other bigger problems) you're good to go! I'd love one of these in a survival go-bag.

Also the best part is there's no batteries to recycle or lithium to mine!
