Nitecore Tube keychain flashlight teardown. (Half watt LED)

A test of, and look inside the little Nitecore keychain flashlight that packs quite a punch. I'm guessing this might be a real unit, but it was bought in eBay, so there's no knowing. However, it's pretty well designed inside with a beefy 5mm LED with a higher power rating than normal and a well protected lithium cell (Which seems to test at 70mAh).
