Because my cerebral cortex developed inside-out during gestation, that is, the second layer of six layers of cortical neurons migrated through the first layer, leaving neural connections as they want, and the third layer migrated through the the first two, and finally, the sixth layer of neurons migrated through the other five, my brain has decided that this light, and the Nitecore TM9K single cell 21700 at 9,500 lumens desperately need to be side-by-side review compared with each other. If I can't search and find where this has already been done before I get a chance to do so, I will be first.
