haha, thats the exact name of my own thread i made some months ago:
Theres alot of 18650’s listed in that thread a couple of posts down all listed with lenght x width in MM so you dont have to go searching through chinese websites trying to find that info. Was hoping some day that thread would help someone else.
I did alot of research. there are some 14500’s brighter than an e03 (but not much), but they are far more expensive and they dont run for very long.
As for the quality of the DQG 18650, from all the things ive read about their other flashlights, they are top quality. I didnt hesitate once i found they werre making the DQG 18650, i pulled that trigger the minute they were available. Only thing is that its a twisty, and not a clicky. Cant get a clicky that small becuase of the size of a switch. So im delving into the realm of twistys to see how I like them.
