That Inova X1 single AA powered LED, have you ever EDC'd it? I have an ARC AAA now on my truck keychain but I wouldn't mind something a little brighter and would prefer AA over AAA as I don't have a lot of non AA gear left. The ARC AAA the only thing holding me from droping AAA's in my gear completely so if the X1 wouldn't be too much bigger then I could switch over.
