I use the 168A extended "3x 18650 cell" set up exclusively with the EO-13. I find this to be one of my "if not the best:thumbsup:" all around useful lights I own, It's a great "light up the whole road flood beam" with easily 200 yards of throw. As far as a lot of people on hear complaining about heat, well I think they are either over exaggerating, or have never used a small high power LED light. I easily get 45 minuets of run time with this light and on MANY occasions I've ran it for the entire 45 minuets straight out:twothumbs. Non of this 5 minuets and then worrying about overheating. A good way to judge heat danger levels is this: As long as you can hold the metal section of battery tube directly over the cells then the heat is not endangering the cells, the same goes true for well heat sinked LEDs, if you can hold the head then the LED is fine. The heat only after maybe 20+ minuets get slightly uncomfortable near the neck of the light while the head is very hot, but there is nothing in there that can become damaged "incans don't care about heat:thumbsup:". LF only has to have that statement so people don't sue when they burn themselves with the head of the light, it's the batteries that you have to worry about, and as long as you hold the light it should be fine. Also I saw someone post about a oval beam shot. That's what came with my WE, and it drove me nuts. The EO-13 "mine at least" is the most perfect beam I've ever seen with no flaws including being perfectly round "I'd be quite upset with a oval beam "though some people like them:thinking:."
This is a great camp light "#1 I use" but you have to be aware it's extremely bright and people around you "especially in crowded areas" won't appreciate it to much:mecry:!
