How much Ampere does an average 1x18650 flashlight drain?

Hey, when it comes to 18650s and vaping you should always make sure they are high drain batteries like the LG2 (i heard). How is that with flashlights? Like for example an klarus xt2c, blf a6 or thunite tc2? How much do they drain when in the turbo mode?Thanks via /r/flashlight http://ift.tt/2tajqFv
