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

Yep, that’s the non-BLF edition :slight_smile:

Very interested.

Definitely interested.

yes please count me in

Very much hoping for nimh support.

Yup, I would definitely be in for this as I quite like the host light already.

Interested!

Heh! First post.
Count me in, for a 14500. I would like to have one with clear or no anodisation.

I’m in.

Welcome to BLF!

AFAIK, the project is still alive. kikkoman, Tom E, Toykeeper, gchart and Lexel are figuring out the optimal design and components to invent a driver that can handle both Li-Ion (3.7V) and NiMH (1.2V). Currently, some of these people may be on summer vacation or busy with real life™. ;-) Once the design is set Sofirn needs to check if they can source the appropriate components to build the driver.

Don’t know if it has been sugested: machine a poocket-clip/slot so the clip can be reversed.
I’ll take two either way!

Very interested Thank You.

Interested! :D

:BEER:

I am sorry if these are dumba$$ questions - and please note that I really thank appreciate the work being done by all the involved - but…will this light (with the Anduril FW) give it’s “full power” if running an Ni-MH/Alkaline battery and also being able to take 14500s Li-Ion?

I mean…I know that most of us seek to have the possibility to run the light with both types of batteries, and many of us don’t use 14500s, but will it be worthy the effort to make a “double battery type” driver?
Wouldn’t it be better to try to have 1 running only 14500s Li-Ion and another AAs?

Sorry if this question is dumb or if it “ruins” all the original idea for this light! I just feel that it may took a real “while” to get to a conclusion on this, and maybe meanwhile we could have, at least, a SP10S running only 14500s with Anduril.

Sorry and thanks in advance! And good work to all :wink:

There is no such thing as dumb questions MascaratumB. There are only dumb answers. ;)

While I fully understand your questions and the intention about it to get things done faster, I need you to wait for some of the "driver experts" to answer. AFAIK, building AA 1.2V NiMH or 14500 Li-Ion support is quite easy. The real challenge is to get the best of both worlds in one flashlight. And that's were the details begin that Lexel, kikkoman and the others are working on. It requires a quite sophisticated boost driver with a stable regulation and little standby drain to make this one a story of success. Personally, I expect the flashlight to run less bright with 1.2V NiMH cells but that's just a lay opinion based upon my experiences with other boostdriven flashlights like SP10B or SF14 V2.0.

So, why do most people look for a dual-use flashlight that can run both with NiMH and Li-Ion? I must admit I don't have any answer here. For children and for the sake of a better feeling about safety people like to use NiMH or alkaleaks. Some people might look for a flashlight with a great and complex UI while still being able to feel carefree using harmless NiMH/AA cells. I don't think it would pay for Sofirn to make two versions. I presume this project will either end with a 14500 only version or - hopefully - with a dual-use version that can handle both battery types.

Seems cool. Interested

The problem with dual-chemistry drivers is that quite often the mode-spacing is fine for one but garbage for the other.

One will be visually linear, whereas the other will either have horrendously wide spacing between 2 modes, or will be compressed between 2 modes as to almost look like the same brightness for both.

Worse when the cell’s voltage (either chemistry) starts dropping.

Oh yeah. When using alkaleaks, quite often the light completely craps out when the cell’s still got like half its juice left inside. I’ve even got 2×AA lights that start blinking then just turning off when there’s plenty of oomf left in the cells.
