I just got a green SP10 Pro in the mail today. I wasn’t going to get one, as I have three SP10s’s. Getting to pick it up for just under $23 all in with battery/charger pushed me to go for it.
I do like the older host better. As has been said before, it’s a little shorter and has a better tail cap. The new clip isn’t great, but it is better than the old one.
Anduril 2 was actually a deterrent at first, as I didn’t want to learn all the new procedures compared to Anduril 1. But the few extras it has are worth it (I dig the timer on the hybrid memory and the ultra low moonlight). What blows me away is this thing’s performance on NIMH. I don’t know how long a battery would last, but its output is pretty amazing. It’s decent with a 14500 too, though it doesn’t outshine the competition (sadly, pun intended) like with NIMH.
It will definitely be my EDC for a few weeks to see if the happiness of the honeymoon phase fades.
Those threads I’ve seen elsewhere (can’t recall which post/thread) and seems a hybrid of Trap/Square. An album of such and the nitty-gritty of thread form from Machinery’s Handbook.
It would seem like a stub Trapezoidal thread with a wider root than the standard (cutting tool plunged deeper than the 1/3 pitch). Perhaps to accommodate a square thread also (wouldn’t that be clever?) or some flashlight designer rewrote the book on thread form (the handbook is the definitive author on machining standards - else of special in-house needs).
I don’t have an SP10 Pro but my SP10S and the SC21 have square threads. Sofirn’s machining is correct on those 2 lights. So I might deduce some voluntary screw thread form was made or they allowed more clearance than what is standard.
Acme threads have been superseded for many years now. Same as the Whitworth. (29º and 55º respectively; inclusive angles). The term Acme is a misnomer for Trapezoidal as simpler to remember and write. Some artifact items are still made BSW (British Standard Whitworth).
That ACME company is vintage. Wonder if Chuck Jones was inspired when creating the popular Wile E. Coyote character? (wiki)
So, thanks to thefreeman (nice adapter) and gchart, I was finally able to reflash my SP10 Pro .
This light will get a 5000K 519A if I can get one. Installed gcc-avr und the Atmel files on my Pi, hopefuly I can get Andúril to compile on this system. One thing to do: Kicking out the reversed direction after ramping up.
There’s not much space in the battery tube. None of my 14500 fits. They’re all protected, Olight, Klarus, and Wuben. So I’m stuck with Eneloops. Could be worse.

There are two raised pads on either side of the driver’s positive contact to prevent reverse polarity issues if the cell is installed backwards, thus flat top cells won’t work. I’m running a Keeppower P1450C2 protected 1000mAh 4A cell in mine. It’s a little long (51.5 mm), but no problem. Have Vapcell Gold 3A button tops as well (50.5 mm). Great cells and run them in a few of my lights.
