Thanks for the warm welcome!
This Arc says First Run #793, but the person I bought it off of sold it as a Second. IF a warranty still applies to someone other than the original owner, then that would be great. But I can only assume that I have no warranty on this, unless someone on here proves me wrong.
Anyway, I am amazed at the amount of light that this puts out. Dark hallways are no longer a problem to see down when it's long! I have an Arc AAA LE that works well, but needless to say, the Arc LS . . . . . . . .. .like I said, needless to say.
Only 'mod' I have done was to wrap paper around the 123 cell so it wouldn't rattle in the tube. I have purchased many (too many, perhaps) flashlights in the recent past, and fortunately, this one will be the last for a good long while!
