I'm considering picking up a Surefire E2L. Aside from not owning any Surefires or any lights with optics, I also really want a 17670 body tube to use with my Nitecore Extreme. I noticed however, that according to light-reviews.com 17670's will not fit in the E2L body. I now I've read about people using 17670's in their E2L's though. Has there been a change in the E2L or does it just take some modding to make a 17670 cell fit?
