OK, the current story is that you got an order confirmation with 15 days lead time, not a shipping confirmation. I'll believe labsafety shipped you those things when you post here that they're actually in your hands.
As for the brightness, yes, you should be able to see around a dark room with the bigger ones, once you are night adapted. It's not that they're insanely bright but rather that night vision is amazingly sensitive. There is a type of "flashlight" called a betalight which is basically a small circular version of those tubes in a portable package.
