What is the Comprehensive performance about this flashlight?
Someone who used it give some suggestions ,thanks in advance !
I don't know of any other 8xAA battery lights out there, so it is brightest AA by default. It is expensive, but Fenix has a good reputation. The light was released a year ago and Fenix was exaggerating lumens a little at that time, but it has been measured at over 500 lumens. There are reviews here:

Other than it's brightness, here's something that shows how tough the TK40 is.

Wow! Great read. I do have new respect for Fenix now.
It's pretty impressive. I just found that our local Army Surplus store carries Fenix flashlights and since I opened up the TK40 case and tried it out, I haven't been able to get it out of my mind.
No its not 630. Its been measured at 550 OTF. Its the brightest mass produced AA light. My 9-AA mag 1185 beat it by 50 Lumens though... so its not the brightest AA overall.
My brother has had problems with his switch, and the parasitic drain bugs him sometimes.
