Hi roadkill1109. Not sure what your tint preference is, or even if you have one, but the little SC60w is one sweet light. I have several ZL's, including the SC600, but the SC60w is probably my favorite. I just love the how ZL does warm tints. Getting ready to order my 4th SC60w! That will make me 3, new in the box, in case the one I'm carrying now ever gives up the ghost. You simply can't go wrong with the SC60, or SC60w. 18650 is my favorite form factor because of the super capacity available in these cells. I won't even try to talk you out of the SC600, because it is also a really great light for it's size. Hell, I'd even suggest you get both! lol But if you're set on only one right now, grab an SC60 or 60w, while they're still available. You won't be sorry! Good luck!
