I’m preparing a review posting of the SP32, I am trying to determine the difference between the SP31 and SP32. I think the only difference (that I can see) is that moonlight on the SP31 is 1lm, and is 3lm on the SP32.
Anyone else know?
Yup, I was using 14500 batteries on both when I took the picture! And I agree with you: with a 14500 it gets more “pinkish” (the first one I get, not the one that arrived today).
With a Ni-MH or an alkaline, the tint gets closer to a neutral white, although there are some nuances of pink, mostly on the outside edge of the beam.
The one I got today, in the real center it is a bit yellowish, and then white, and then yellowish again, and then neutral white!
(the picture on the left was taken in HIGH mode with Ni-MH battery, about 40cm away from the wall; the others were taken about 1,5 meters away from the wall, HIGH mode with 14500 battery)
I also noticed that with a 14500 battery, both lights have PWM in ALL modes (at least in the photos)! With alkaline or Ni-MH, only HIGH mode doesn’t have it!
Sorry, i have the SP32 but I cannot determine how many lumens it puts on ML mode! Nor in any other one :person_facepalming:
We felt sincerely sorry to hear that Sofirn SF10 caused troubles for you. And we would like to assist you solve issues if you would like to email us to Aliexpress or Amazon or sofirnw@szjinb.com.(I am not login in BFL everyday, so it is easy to miss some PM messages. Sorry again ) My colleague Cissy had arranged a new one for you 14 days ago when she got your message on Aliexpress, so please keep eyes to the second parcel.
Moreover, I want to say “thank you” to MascaratumB. The New black package of SF10 was used at the first time. We did ignore elements from the feedback. But We have made some adjustment on package since the feedback came. Honestly speaking,it is not so easy to avoid all damage in shipment. However, we would like to improve the package continuously, either of all products. Everyone is precious for Sofirn, no matter customers or friends in BLF. It is our honor to get your feedback or suggestions.
What’s more, we hope that we are able to incorporate some of the features your guys had talked about.
Have a good time in BLF. If there are anything else that we can do, please feel free to contact us on Aliexpree or Amazon.
Tracy from Sofirn
Tracy!
Has you said, I contacted your services in AliExpress and a solution has been given.
I exposed the situation here when the first arrived, and I did the same when the second arrived so people here on the forum know that it was solved.
My new flashlight arrived last week, as I pointed out above in this post: Sofirn SF10 and SF12 review - #24 by MascaratumB .
I’m very happy with the solution and also with your costumer services! The situation was solved quickly, and I guess that Sofirn has also learned from this situation. Long shipping sometimes results on package damaging, so better boxes or wrapping can make the difference.
Ex: this new box was a bit bruised, but a it is a stronger cardbox it held more pressure and protected the flashlight! Also, it had bubble plastic protecting it.
It is good and important to see that manufacturers “listen” to us, costumers, and improve with our suggestion and ours/yours mistakes.
About things to be improved (some already mentioned) in my opinion:
a) better and more protective flashlight boxes
b) better and more protective wrapping of envelopes for the flashlight boxes (and batteries and chargers)
c) the logotype printing (not scratched and well aligned, as I have seen some lights - my SP32 included - with scratched and not aligned logos)
d) the user interface (from Low to High with hidden strobe through double click)
Thanks Tracy for the support and for stepping in to check this situation!
I hope Sofirn can evolve and keep on bringing us nice flashlights!!
Or better yet, doubleclick to highest and no strobe. 
Eheh, it could be that option too :smiling_imp:
Yes, the driver is definitely the weak link on these lights. Simple drivers should, IMO, be always L>M>H with no memory. Anything extra like strobe and SOS should come after high
Today i received SF10. It is a very good AA EDC flashlight but not a 14500. Very good construction. I think tint is about 5000 - 5500k and power is about ~100 lumen on AA .
SF10 looks nice, today with special price only $6.95, just bought one :person_facepalming:
! Sofirn SF10 AA/14500 battery with special price for 5 days !
Ok. I removed the pill of the SF10 to change the emitter, but I forgot about the placement of the O-ring in front. Is the O-ring between the lens and reflector or is it outside, similar to Convoy S2+ ?
The O-ring fits between the lens and the bezel, not the reflector!
Some weeks ago I put it between the lens and the reflector and while screwing it in, I broke the lens!
So, o-ring between the lens and the bezel 
Noted, but do you mean while screwing the pill in? It’s the SF10 we’re talking about, right? The SF10 has a removable pill and a fixed bezel. Didn’t know that the glass lens is more susceptible to breaking if the O-ring is placed between the reflector and the lens.
Yes, the SF10 is the same of the picture posted above on post #35 I called it bezel because I don’t know what to call it! But it as a removable pill + reflector + lens+ o-ring
What I mean is that I was once screwing in the pill and made more pressure than I should. As the o-ring was between the reflector and the lens, and not between the lens and the “bezel”, the strength applied was too much in a part of the lens, so it broke. The O-ring, besides sealing, may have that “shock absorber” funtion. The hard surface of the lens vs the hard surface of the bezel made it crush.
When the reflector is just below the lens, it will apply the same pressure in all parts of the lens and the o-ring above the lens will absorb it and hinder the lens to have friction in the bezel
Conclusion of this: I had to order another lens that arrived yesterday ! In some weeks I’ll have a new driver, a new emitter, and Sofirn SF10 will no longer be what it was :smiling_imp:
Exactly what I have in mind. The SF10 is compact and feels very solid because of its hefty battery tube and good knurling. More importantly, it can take a 17mm driver and 16mm LED base. I just wish mine came with a brass pill instead of cheap aluminum.
Speaking of the lens, mind if ask the diameter and thickness of the new lens that you ordered? I’m thinking of getting an Acrylite 18.00 mm x 1.60 mm. Do you think it will fit snugly?
Nice! If I weren’t hip-deep in AA lights, I’d be tempted to get one or more.
’Though if the SF11 goes on sale, I’m totally there…
I think all of my flashlights have the o-ring as the first think after the bezel/head piece, otherwise it wouldn’t work as a means to keep water/dust outside the flashlight
Just a tease on how mine is looking right now :sunglasses:
The Emisar D4, as far as I remember, has Bezel > Lens > O-Ring > TIR !
I bought clear glass lens, super cheap but effective, on a AliExpress store. It has 17.6 x 1.4 mm! I guess that 18x1.6 will fit properly! The stock lens is 18x1.5
Mine has a brass pill, but it is thin! I’m thinking about putting a “good” driver, but I ain’t sure it it will work! Maybe putting some thing inside the pill helps on heat dissipation 
Gotta work on that!
By removing the hard coating, you effectively made the scratch/dent barely noticeable.
Finding a “good driver” shouldn’t be hard. You just have to decide if you still want AA NiCd battery or go lithium all the way.
