The 3xC is about ~3.6 - 4.5 volts, and the single 18650 or 26650 is also ~3.7 - 4.2 volts, so voltage ranges are the same for both configurations.
Current, which I think is probably more important as far as brightness, would be determined a lot by what type/brand of batteries are used.
So, all in all, I think that the brightness range would be the same, based on which type of C or 18650/26650 battery is used.
I didn’t do it for better brightness, but mainly to have a smaller, less wieldy light, plus, I’d rather use a single, rechargeable battery, rather than 3 batteries. If brightness is the same or better, I’d go with the shorty configuration.
I think that when I first came on this thread, someone mentioned that there was some thread where someone figured how to configure two 18650s in a DST to be in parallel. I don’t remember what that was, but maybe someone else might.
I’ve been thinking about modding a DST. I found this thread:
and, I was looking at the picture of the pill (5th picture). I haven’t started disassembling mine yet, but the positive contact in my DST does not have a spring, but rather a kind of metal “flap”.
So I’m wondering are there different versions of the DST, some with a pill with a spring like that, and some that don’t?
Embarrassed :(… Just saw that in this other thread:
Thanks :)!!

Edit: P.S. This may have been said before, but I was messing around with the DST that I have that has the body from the A8 clone, and I notice that that body is able to screw in directly to the head part, without the switch section, which makes the “shorty” DST even shorter. Also, when you do that, you can use the tail clicky switch on the A8 clone body to turn the light on/off. When you do that, that “shortier DST” is really almost pocketable, and definitely more EDC-able. I’m thinking that you also grind down the bezel a bit, maybe 1/8”, to the point the crenellations are gone, and reduce the length even a bit more.
I did say “almost pocketable” and “more EDC-able”, plus I was trying a little “tongue-in-cheek” humor :)… But, I think that it’d fit into like cargo pants type pockets (which I don’t have).
Hi m007, I forget at the moment. I’ll dig through my orders to find out though. From I-O, IIRC. Did I link it in my mod post?
Edit: It is in the mod post, click link in my sig to find it. Enjoy.
