Depends on the LED but a typical single cree XML LED flashlight is only going to need about 2-3 amps max so 8 amp cells should be fine unless you are using them in a very powerfull single LED light.

First question is what brand are they. There are a lot of crap CHEAP 18650 out there that are more dangerous than useful.
