Best Flashlight Botton Line:

When searching for the best keychain flashlight you have to remember that this is not going to be as powerful as the AA Flashlights or even as powerful as the best AAA flashlights here. The main reason is the LED and secondly the size. Although those other lights are great options, they are not really designed for a keychain and thus are just too big for the job. So like I have said in other posts, “pick the best flashlight for the job at hand and don’t try to pick a one size fits all kind” you will just become frustrated and might not even use the thing.
