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

How old is the firmware on the light?

Can anyone tell me what kind of thread Sofirns sp10 pro have? square cut thread or diamond cut thread?

Is the present (fixed bug) SP10 pro sell on lazada or shopee?
Any know about this? i don’t want to buy the first run has bug.

Diamond cut

did you read post 1935?

you will have to buy to find out.

If the light has a blink at top of ramp, it is the NoBug version

I finally got mine in the second try (first one was lost in shipping). Was also surprised by the blink at max but it doesn’t bother me that much. Simple mode gives a workable low but I like to have lower settings so advanced mode it will be. It’s actually one of my biggest AA-lights but I’ll edc it a while, does need a better clip thou so looked in the lights-drawer and found the one from the Utorch UT01 best fitting so will use that one for a while.

Thank you,
i read the review in sofirn sp10 ver 3 here:Sofirn SP10 V3 Flashlight Review - ZeroAir Reviews
He said the sp10 ver 3 have square cut, so it is better finish than the pro version, i think.

Thank you

Do these work with flat or button top protected batteries?

I’m guessing these use high frequency pwm?

You need button top batteries because of the mechanical reverse voltage protection. Not sure if protected batteries would fit.

Tried my protected Eagletac’s, they fit and work fine so it seems any buttontop will do. Btw: you’ll never find a 14500 for the price of ordering one in the light and that one will fit.

Appreciate it. I have some keeppowers already and no light. Thanks

I have both lights and just looked at the threads side-by-side.

Both lights use diamond-cut standard threads. There are no square cut threads in either light.

Also, the hosts (ie the aluminum parts: head, bezel, body tube, and tailcap) are 100% identical. All parts including the threads are interchangeable between the two lights. This is not surprising since the SP10Pro is just an SP10v3 with a different driver and different name stenciled on the anodizing.

Thank you so much for such detail information :heart_eyes:

The threads on SP10 are what many call square cut.

To be precise, I don’t think they are actually square cut. It seems to be trapezoidal thread. Regardless, it is not triangular cut threads you see in many cheaply machined lights.

Edit: I cleaned the lube off and looked at it more closely. I think the threads of SP10 Pro are indeed square cut threads.

I stand corrected. I thought they were triangle-cut threads, but I didn’t look close enough. They’re actually very small square-cut threads.

In any event, both the SP10v3 and SP10 Pro have the same threads.

Thank you guys, that picture help to see very clearly.

I would buy this light with Nichia 519A installed and without any type of blink on the ramp. Hope this will be correct soon

These are not square cut threads - photos above are not sufficient to really tell, though. They are trapezoidal threads with the crests maybe a little flatter/wider than some. Not all that different than what’s on the Convoy T2/T3 and many other lights.

It can be tricky to see these clearly sometimes especially if they are shiny from grease or have direct light on them. Mildly backlit against a light background and with a low power magnifier you can clearly see that they are not true square cut at all. But that’s fine…they’re well machined and finished, feel great and work very smoothly, cap goes back on effortlessly, which is what’s important.

At least the thread’s fell like there gonna last on the sp10pro. A sp21pro that I bought, only catches on the last turn.

With the stock 33.9mm long battery, my SC21 Pro has more than just the last turn.

Are you maybe using a longer battery?
