Andúril 2 coming to Sofirn - The general Sofirn development thread

Gearbest did quit. Don’t know why this project cancelled and don’t know how many people still want this light. But Sofirn do wanna make a new light of >10K lumens.

I personally prefer 4* XHP50.2 emitters.

Correct me if I am wrong but did not Sofirn plan to build a Q8 with 4x XHP50.2 some months ago, did they? That should be feasible without too many changes except for the driver and the extension carriers (2s2p instead of 4p IIRC).

A driver for 4 xhp50.2 might be tricky since I don’t think you can use a FET design. The xhp50.2 are known to be quite sensitive to current consumption and are easily burned up by 2 x 18350 cells. Maybe there is a way to use a FET and still limit the max current? I think Texas_Ace was able to do this with 4S 18650 and 3 x xhp35. Careful selection of MOSFET and springs in the carrier were able to keep the LEDs in the safe zone.

I’m not sure about a Buck or Boost driver designs. Producing 10,000 lumen might require a very expensive driver design. Lexel probably knows for sure since he designed a 30,000 lumen buck driver for 10 x 18650 cells (21v IIRC). His lower powered bucks are still quite pricey.

SP32 V3 maybe with hi cri led, deep pocket carry black clip(silver clip looks cheap), shortcut to moonlight. shorten the length of the light and lastly ability to indicate batt voltage. :slight_smile:

Yea, me too. A small sized but feature pack like Emisar D4. I don’t need 4k lumens but
2k will be good enough without the extreme heat.

I would like to wish the driver is built on the principles of drivers Sofirn SP33 (XHP50) - with stabilization modes, thermal control, only without stepdown by timer.
Turbo mode 6000-8000Lm would be enough.
Light of >10K lumens is certainly interesting, but less massively it seems to me and may require more emitters XHP50, which will increase the price. I think such a special monster should go second in turn.
Thank you for communicating with consumers!

I even pointed out that, re the SC31. It’s a really strong clip, no complaints, but the same typische silver clip just has a cheap look to it.

The 1buk DC clip from FT fits perfectly on lights with a narrow groove (eg, the Nitefox UT20), but on lights with a wider groove, it’ll go (more) lopsided when clipped onto anything, and probably eventually wear out the ano in that location.

Yes.

Get the Sofirn SP32A V3.0 with the SST-20 4000k 95CRI.

We’ll get be getting more throw than the XP-L2, and it’s cheaper for manufacturers too :slight_smile:

You should checkout the purple on the Convoy S2+. They chose the perfect purple tint. My wife likes it.

do you mean body color or led color?

Suggestion — as someone asked above:

I suggest putting a sticker on each light identifying the software installed on it.

So if you change the programming of the driver, change the sticker as well.

One reason why NarsilM blinks out a version #

Body color

change Q8 to 4*XHP50.2 10K lumens version need to change the driver as well as the reflector due to the voltage and size difference. All those tests again…

So what I am think is why not try a new design? But you guys know Sofirn team is not good at good looking design.

At this time some say hope Sofirn can take over the Utorch UT03 groupbuy.

I noticed this project was started one year and a half ago, that’s why I’m asking how many people still want it.

Do you want to count those who want to buy Utorch UT03 in this thread or create a new one? Or other survey methods?
I’m definitely interested! I am in!

21700 lights with protected cell fitment for those who will not allow unprotected cells anywhere near what they value.
Differentiation is the key to success in this already crowded category of budget lights.

I remember the Utorch UT03 and was bummed when it was shelved. I’m glad that it is being looked at once again.

I recall the price being a bit more than what I was willing to spend, but I had the feeling that it was a quality light. The machining looked amazing.

Could you give us an estimate about the price it might be?

Also, please consider offering it in NW!

For me, the UT03 is not that interesting anymore. Since there’s a bunch of high powered soda can sized flashlights already. The MT03, M43, and ROT66 is already adequate. However, I would be interested if it had USB-C recharge and functional cooling fins to allow it to sustain high output in order to be practical. I wish there was USB recharge with the ROT66 because I hate taking out the batteries to recharge so often. It’s a big hassle.

Speaking of sustaining high output. Maybe Sofirn can come up with a new flashlight/host with excellent heat dissipation capabilities to sustain 3,500 lumen output from a XHP70.2 or 4x or 7x emitters from 21700 cell. This would make it a very practical and unique light that does not yet exist. Here are some examples of functional designs that maximize surface area for heat convection and radiation.






Upgrades to these lights:
SP10A
*Built in USB C charging
*Narsil or ramping UI like current SP32 V2
*Side switch like SP32 V2
SP32 V3
*Deep pocket carry clip black
*Built in USB C charging
*Power bank function
*Optional 21700 battery version as well
C8F 21700
*Built in USB C charging
*Power bank function
*Narsil or ramping UI like current SP32 V2
*Side switch like SP32 V2

Let’s do some tweaking on what you proposed:

SP10A

*Ramping UI like SP32 V2
*SST-20 emitter option(5000k/4000k)
*Side switch like SP32 V2

SP32 V3
*Deep pocket carry clip black
*Built-in USB-C charging
*Optional 21700 version
*SST-20 5000k/4000k

C8F 21700
*Same UI
*SST-20 5000k/4000k
*FET tailcap switch only instead of E-switch+tailcap switch

That’s about the only thing they should change.
Their lights are already great, and these changes are extremely easy to implement, unlike USB charging/powerbank function and a smaller NarsilM driver, and less costly.
