No, not On at all times, (that would indeed be wasteful) but just the regular Sofirn Indicator LED - powers On for about 5 seconds with the color that would indicate the power level: Green = Full or charged, Yellow = Mid, Red = Low, Flashing Red = Charge or Charging, then after the 5 or so seconds had passed, it goes Off (well, not for charging or "please recharge" blinking Red). This would really be a nice feature to have in Anduril as well (especially in lights where you can only have one indicator light in the switch, just like the SP10 - It could be a mode of the RGB AUX LED's as the Anduril Indicator or Button LED code is only for monochrome)
The one I ordered from sofirnlight.com has arrived. No battery but additional magnetic tailcap is how I can tell it’s not the one I ordered on the same day from AliExpress. My first thoughts are about bright it is on an AA vs one of the cheap zoomies that are AA/14500. I’ll get to test it in darkness a bit later.
That was fast, congrats.
Now that some of these are starting to show up in peoples’ mailboxes and I haven’t heard anything yet from Sofirn about providing a flashing kit… If there is interest, I may be able to put some kits together. I’m guessing price with shipping to US would be a total of $10. Is there interest at that level? Note: as has been mentioned before, the flashing process isn’t exactly the same as the t85 and t1634. Basically, it’s different than any Anduril flashing you’ve done before.
That’s a very reasonable price.
I already have Attiny416 XNANO and your adapters, is this setup future proof for upcoming builds or should I get your flashing kit.
I don’t foresee any of the flashing methods I’ve used going away any time soon. Especially not that t416 XNANO as that’s using Microchip’s own board and flashing utility. And the pymcuprog method seems to be backed by Microchip as well, so either should be good too. The jtag2updi is a community project and it’s future is unknowable, but I think at this point probably only TK (and occasionally myself) are using that at least as far as BLF is concerned.
Okay great. 
Wut!? Already?! I ordered on day 1 and it’s still in Yanwen’s sorting center :person_facepalming:
Enjoy being one of the 1st on the planet 
I’m in the UK. I ordered on the 21st and it was “on the way” on the 23rd and “Your parcel is at our national hub” by the 30th. I’m surprised too as the AliExpress order was made first but I think that’s still in China. Can’t really tell from the Ali tracking.
Just tested quickly in darkness and the SP10 Pro on an AA is a bit brighter than a cheapy zoomie with the same beam spread on a 14500. The only thing I’m unhappy with so far is the button. It’s super hard to find by feel and I honestly wish there was a tail button.
thank you for taking the time to post those pics… 
Anduril could definitely do more with aux LEDs. The main reason it doesn’t is because of its focus on portability across many different hardware designs. It generally keeps important functions on hardware every device has, and uses the optional hardware only for optional functions.
That could be changed, of course, but it would need some major refactoring to keep the complexity manageable. RGB LEDs weren’t part of the original conceptual model it was built on, so they have always been sort of an awkward fit.
Despite the awkward fit, Anduril does support RGB button LEDs. They’re used in the Noctigon K1. It changes color during use to indicate battery voltage real-time.
I’d like to see that feature used more often, but it makes the wiring difficult… and would likely not fit into a SP10. It may also not work well electrically on a dual-chemistry light, especially with a relatively small cell, due to the overhead and complexity required to convert voltage.
RGB buttons also aren’t used much because most supported lights so far use multi-LED designs with TIR optics… and those typically have front-facing aux LEDs instead of a colorful side button.
Nice. It sounds like it could be a good upgrade.
My favorite beams so far though… have been what I get when I tint-mix ~6500K and ~2700K emitters and set the CCT somewhere around 4000K to 5000K. This pulls the duv down so far it makes everything else look green. One of these days, I’m going to have to order a KR4 with XP-L HI 1A+8A so I can spoil myself with a rosy EDC beam. Of course, then I’ll probably complain that 219B is too green… 
Got a kick out of this pic from the Aliex album….hope it’s not THIS big…or the hand model is an infant ;–0
There’s plenty of reviews of the SP10 V3, but I posted some personal photos of that light with beam shots here. I really liked the first sample I received, and the LH351D 5000K was right up my alley tint wise. Hope the PRO doesn’t disappoint like the V3 did from a quality standpoint.
This looks like the 21700 version that I’m dreaming of!
SP10Pro mass production will make Black, Red, Green, Blue available.
If you need diffuser, and magnetic tail, you can find on our website!
Will there be matching magnetic tail caps or just black?
Yes, Barry, can we get matching colour tail caps?
I just ordered a set with the additional black tailcap but it would be really nice to get one that has the same colour as the body.
yeah, matching magnetic tail caps will be available in the future. But currently only black caps is available.
Wow very nice, thank you Sofirn
Will it come flashed? If so I would be interested.
I am confused about the black version. Sofirn’s website doesn’t have a magnetic tailcap included but the Ali store does?
