Just received my Arc LS - now I understand what all you flashaholics in the USA are raving about! Makes my 2 lithium AA reactor look very sad (and green) indeed. My question is how can I tell that I've received the LS1 rev. 2 version? The only identification code on it is "LS1 - 2659". I don't suppose it matters all that much, but seeing as it was advertised as being the rev. 2 model I'd like to think that's the one I'd received.
