Sofirn SP10 Pro (AA/14500/Andúril 2) - now available!

Perfect. If there were any issues with contact and filling the gap, perhaps a washer could be included with the clip? At any rate, glad to see this light happen and appreciate all of the smarts and work that went into it!

For those who do not want to use the clip I had this in mind, same as Hank‘s ring with a small lanyard hole.

I find it most important that the clip opens wide at its end. The original KR1 clip is wonderful. The clip Jared has shown seems to be of this kind, at the same time allowing deep carry.

Thanks for the updates on this Lux-Perpetua :wink:

I will not focus more on the pocket clip, since you already addressed that issue :wink:

I will, however, focus in one aspect I mentioned before: length! Of course, this is a Sofirn light, with a “Sofirn style design”: long screwed-in bezel.

But, how feasible would it be to diminish the size of the bezel (and eventually reflector) to make the flashlight slighty more compact?

I’ll take this photo as example:

The SP10 is the longest, due to that bezel. The Manker E11 (has a magnet, making it taller) and the Skilhunt M150 (all side switches) are more compact than the SP10, and it is mostly due to the bezel lenght. Trimming it down a little bit would:

a) make the flashlight more compact
b) not have impact on heatsinking (hoping that the head structure does its’ job well)
c) make it more “pleasant” to the look and attractive .

Of course, I will not be picky about this, since the train is in march, but I would not be ok with myself if I didn’t mention this aspect!

And once again, thank you very much for all your work :wink:

Here’s another example of what I mentioned before.
I tried the FWAA bezel on the SP10B host for illustrative purposes (the bezel doesn’t fit).
Skilhunt M150 > SP10A > SP10B “shorter” > FWAA

It would be nice to have these 2 AA/14500 lights as the “shortest” in their category :innocent:

I’m all for making a light shorter, but not at the expense of the quality of the beam. The SP10S is already fairly floody, and shortening the reflector doesn’t seem like a good idea.

Not having the SP10S, I only have the SP10A/B, and they are not that floody. Actually, when I first hot them, both the SP10A and the SF14 were quite throwy for AA lights! The thing is, mine have XP-G2 while the new one has Samsung LH351D.

I do get your point :+1: but now we may start entering personal preferences, about floody or throwy.
Given that the SP10 Pro will be an EDC light, I would prefer it floody for looking and short/medium distances. If I want throw, I can pick the GT Nano. But again, this is about personal preference in the beam.

Overall, in terms of design, I would prefer and carry a shorter light quicker than a longer light! :sunglasses:

If I remember correctly, deeper reflectors has less spill and larger hotspot and shallow reflectors has wider spill and smaller hotspot. Same hotspot intensity and range.

Kind of. Shallow hotspots are actually probably wider from a fwhm perspective. Deep reflectors get more of a ‘cone’ beam with a bright, tiny ‘hotspot’ and then many ‘coronas’. Shallow reflectors will give a clean, sharp spot and deep are more ‘fuzzy’. I find just under 1:1 (depth:dia) is about the happy place for most applications.

Update (August 15, 2021):

  • OP is cleaned up and updated with latest news.
  • Final custom SP10 Pro Andúril 2 UI diagram posted on the OP.
  • Sofirn has finished creating a prototype driver. The final driver will offer flashing pads to have direct access for a pogo pin adapter to flash new/alternative firmware to the MCU.
  • Next step is to release two prototype flashlight samples to gchart and Tom E for full examination and testing, followed by a trial phase before ramping up mass production.
  • gchart created a custom Andúril 2 hex-file to be used for SP10 Pro:
    • Default mode is stepped ramp with 5 brightness levels
    • Simple UI has full power (ceiling 150/150)
    • Advanced UI ceiling per standard 120/150
    • USE_2C_MAX_TURBO command implemented, i.e. Turbo in the Advanced UI works like in Andúril 1 via 2C
    • toggle stepped/smooth ramp via 3C from ON in Simple UI
    • all latest code updates until August 12, 2021 are taken into account, i.e. firmware revision 2021-08-12

Lumen output as per gchart's prototype testing sample:

(actual numbers may vary in the final product and depend on the used battery and the emitter type/tint)

Mode NiMH Li-Ion
Eco 0.2 0.5
Low 6 16
Med 32 75
High 133 270
Turbo 308 729

Next steps:

  • Lux-Perpetua: create manual for SP10 Pro incl. separation and simplification of the the UI diagrams for Simple UI and Advanced UI
  • Sofirn: check possibilities for alternative (deep carry/captive ring) clips
  • Sofirn: check possibilities for alternative anodizing colors or bare aluminum design (clear coated / sandblasted)
  • Sofirn: build prototype samples
  • BLF community: check for hardware requirements to realize a cheap and reliable pogo pin adapter to be used with future drivers with AVR-1 MCUs.

Obrigado pelas tuas sugestões. :-) :THUMBS-UP:

I talked about this with Sofirn but they have already committed to this design and they are eager to finally bring this model to life. If they had to redesign the entire head it would cause more delays, e.g. testing a new reflector geometry, beam shapes etc.. I assume the SP10S head design was successful/popular enough to keep it this way. However, I do agree with you that a shorter length would be nice with regard to EDC aspirations. A shorter, lighter TIR lens version could certainly be considered in a future upgrade of SP10 Pro.

Agree with your points. A TIR would be a space saver. Not sure if this is a standard size, but if it is, people could even choose their beam characteristics.

Point c is also important: This light needs to be de-uglyfied.

Maybe in another version.

Great updates, Lux-Perpetua!

Regarding the flashing adapter, historically I’ve used a Xnano-416 dev board or a AVR JTAG ICE programmer. But they aren’t super cheap and they do bring some complications (Windows vs Linux, custom avrdude stuff, etc).

So I decided to checkout the pymcuprog project and a super simple and cheap adapter. I think this should be a good universal solution for programming these AVR 1- Series chips. I’ve got the parts ordered. I’ll update when I have more info.

Fantastic!

Ok, next project...get Sofirn to create a high quality rotating angle head light like the Nicron N7/Rofis R2 with dual battery support, good emitters, quality driver, etc. Both of those lights are ok and super handy to own, but the quality is not there on the Nicron and the Rofis (other than having disappeared now...) was rather expensive and a little overdone while not giving great firmware options.

Please add me to the list…INTERESTED!

one more deep carry, captive ring, concept image:

Good to see that this supports NiMH. You might need to slow down the party strobe’s on time - 4 to 5ms should be OK.

Any info on price yet?

Woah, good catch! I don’t spend too much time in strobe modes. I just tried party strobe with NiMH and sure enough, it didn’t light up on NiMH (but is fine on Li-Ion). I tried setting it to 4ms, no dice. So I went ahead and skipped to 6ms and that seemed to work. Thanks for the tip!

Update (August 17, 2021):

  • Updated hex-file (correcting the NiMH glitch in Party Strobe) as been sent to Sofirn.
  • New UI diagram draft to be used in the upcoming SP10 Pro manual
