I haven’t watched the video, but it’s probably from the LT1 Lantern that DBSAR has been working on for a few years. The Lantern uses two different CCT of LEDs, a few of each, and a newly designed driver with firmware by ToyKeeper.

Probably from a Q8 with 3000k+5000k LH351Ds and the Lantern Build.

Sofirn’s New Tech: variable temperature of light

That’s interesting.

I’d like to know more about what that video shows. It looks very similar to what the BLF Lantern does.

That went fast Shocked . Even before the Lantern is out, ToyKeeper’s New Tech has become Sofirn’s New Tech Flat Stare . Let’s see that as that they like what you are doing Smile Facepalm

I’m actually surprised that manufacturers don’t put “ToyKeeper firmware!” on their boxes as a selling point. It’s an instant sign of quality to anyone in the know Smile

Does Sofirn have an intention to give buyers a choice of CCT? For a long time there was no news on this issue.

Sorry for my poor english.

the so called new-tech driver is designed before BLF lantern driver was made. the driver is waiting for a good shell desing.

the only same thing is both of them use multiple leds (half cool white half warm white) to fulfill temperature changing.

But UI, firmware, driver are different.

Yeah, there’s no such thing as a color change led. It’s always two extreme color leds that are mixed. Same as the Zanflare T1 lantern.

I don't think so as this one uses white, red and UV independently. I don't think it would look good to mix these. Wink

However, Barry I would be interested how far the design process for this triple independent emitter light is completed already. Is the last word spoken already or can we (BLF) still give you some suggestions to improve it? Those tiny reflectors could be enlarged like the ones in your C8F triple reflector.

  • Will you offer the driver separately for sale?
  • Will this driver fit into the C8F 21700 host?
  • Can you please check if it makes sense to offer a C8F 21700 with white, red and UV? I think that would sell well, too.

Any news about the AT35 prototype? I hope this one will still be produced.

That AT35 is still badass. Some serious heft.

The AT35 could be comparable to the Convoy M3 or even better if equipped with

  • SMO reflector
  • dual switch design (tail + side switch, like C8F/C8G/SP31 V2.0 and SP70)
  • the C8F or SP70 UI or Andúril if it comes with e-switch only
  • high efficiency boost driver with XHP70.2 in P2-3C (5.000K) and P2-5C (4.000K) bin.

I mostly agree with above. The only questionable point from the list is IMO dual switch in such a flashlight.

I think it would be brilliant to have cool light for throw (zoom?) and warm for flood in one flashlight on demand.
How about a speciality polariser?

The Beam Shaper might be copyrighted technology that Sofirn is not even aware of. Is it even real or just theory and computer animation? What are the down sides, big losses in lumens? We don’t know, but it’s a cool idea.

Hi Barry, I have some suggestions about your recent flashlight launches (e.g. SD05, SP70) that use Sofirn's UI instead of Andúril/NarsilM.

Maybe you can forward and discuss them with your engineering team? I'm sure these updates will not be too hard to implement but they will certainly make your successful flashlights even more successful and more popular.

  • Please remove timer-triggered stepdowns from future drivers/flashlights. I do not see any reason to have both thermal and timed stepdowns at the same time.
  • Please allow a user defined choice of ATR thresholds (e.g. 45°C, 55°C, 65°C) just like HaikeLite did with their SC26

Thermal protection setting can be accessed by 10xclicks:

The light flashes once => turn it off to select 45 degree step-down temperature

The light flashes twice => turn it off to select 55 degree step-down temperature

The light flashed 3 times => turn it off to select 65 degree step-down temperature

 

Eventually, Sofirn can make 45°C as the default setting that will allow a safe and comfortable usage while flashoholics, experts, evangelists and enthusiasts can raise the threshold to a higher value they deem more reasonable, maxing out the full potential of Sofirn's powerhouse flashlights like SP70, Q8 and SP36. There will not be any trade off for customers who prefer a simpler UI than Andúril or NarsilM as they still get the chance to push their flashlights (and skin Big Smile ) to their very limits.

See SD05 that has a 3min and 55°C stepdown.

See SP70 that has a 30min stepdown from High to Medium, even though ATR triggers automatically at 60°C.

There will also be another new Sofirn flashlight that will have a 2min and 55°C stepdown.

Right, so cold winter nights be damned Smile an interesting oversight IMO, but I’m sure they have their reason.

@Barry

Is there any plan to release soon any light with USB charging and E21A emitter(s)?

My suggestion: altered SC31 (as SE21A Wink ) with first low starting at 3 lm

I’d like to see a single emitter light like the SP32A V2 but with Anduril. Seems like it’d just need a driver upgrade.

Sofirn’s stock UI’s usually keep me from buying their lights. I just got the SP36 BLF Anduril and it’s awesome. I even defeated sofirn’s favorite glue to get the driver out and flash the latest firmware build.

Fitting an E21A in a commercial flashlight requires some skilful designing: you can not use a centering piece because the led is small, shallow and fragile, the force of the reflector via the centerpiece easily kills the led. And still the small E21A requires precise centering, even in a reflector as small as in the SC31. I have not seen a commercial solution for that yet.

We need centering rings with pegs in them like a TIR Smile

Remind me again what the advantage of a E21A is over other emitters on the market?

Extreme high CRI and a bit less shift I think. Everything else about it makes it very hard to practically use

Folomov appears to have done it… If only they’d stop inventing goofy battery types and use normal cells.

This is the EDC C2. The one that takes that stupid little 14300 battery.
