Can you get 800 lumen out of something small like this?
This light only has 1 mode, but I’ve been looking for a single CR123 /16340 cell flashlight that would have 5 modes ( L-M-H-F-S ) and put out something like 800 lumens at the bright setting and is cheap.
For $6.36 and free shipping, is this a good deal?
Nope! On first question
Maybe, on the last question.
It probably doesn't have 800 lumens out of the box, but it's very possible to get 800 lumens out of a light that size after modding.
It definitely doesn’t have 800 lumens, it’s impossible with XP-G. It problably has up to 200 lumens on CR123 and maybe 300 with RCR123/16340.
800 lumens on an aluminum star without a direct bond is impossible with XP-G. Try it with a direct bond.
This will help more if you plan to mod.
While it tests the newer XP-G2, even the newer emitter can't do anywhere near 800 lumens without a direct bond, but easily does it with a direct bond.
It say XG-P 
May be a newly released cree led
800 Chinese Lumen…hahahaha
