Sofirn SP70 Alone $50, PM for AMZ US CODE(LIMITED)

How many fully functioning dual switch lights are out there? Zero? Personally I don’t care which way Sofrin go’s, I’m just putting it out there.

I already have several that I built and with lighted tail cap and or switch. It would be cool to be able to select or program the light with Narsil at the e-switch only or program for selected levels at both switches. I just think it’s cool and so do most people I show my lights too, and I don’t know of any manufacture out there that has a fully functional dual capable switch light, but I would buy one if you know of one….

KawiBoy, I totally understand man. It would definitely give driver modes an entirely new depth of group modes and programing.

My apologies if my comment came off as dismissive. I just learned about NarsilM, electronic side switches, and the ability to NOT have a tailcap switch… and you’re over here living in the year 2059 waaaay ahead of me :laughing: hahahah!

Nah no apology necessary, I didn’t take it that way at all…like I said just putting it out there….WE COOL! :+1:

I would Love to see TK take it on and work her Magic! :heart_eyes:

I think ramping takes up a lot of the storage space and that’s why it only has one other mode group.

So with storage space at a premium extra things have to be carefully examined. If we get rid of the strobes, it might free up enough space for something like a battery indicator. That would be something everyone can use compared to a beacon or SOS mode which hardly anyone will use. Know what I mean? It will be noted, though. Who knows, maybe they can incorporate more than I realise.

Mainly I’m hoping Sofirn can get the 2 mode groups from post 72 sorted out and polished. That is a lot of work and there are a lot of details to sort out.

BTW, I have heard that boaters say the GT is a good light to have. The extreme range and NW tint can really cut through the fog, etc… It has strobes and beacon, but no SOS.

I like these ideas because it needs something to differentiate from the already popular L6. But I think I want to see 3x XHP70.2 or XHP50.2 along with the 3x XHP35 HI. Always on illuminated switch that is protected by LVP would be very nice. That way we won’t kill the batteries. I think I read Anduril has LVP for led switches. I hope we get Anduril or Narsil but Sofirn makes some of the best non BLF UIs out there so I’m fine if they use their own UI. The only think I don’t like about C8F is the hold to turn off. I do hope we get side and rear switch with tail stand ability. USB recharge would be nice and makes great gifts for non flashaholics.

BTW, I just measured my Sofirn C8F with my TA lumen sphere and got these numbers w/ fresh VTC5D cell:
3,490 startup lumens
3,250 30s ANSI lumens

Considering Sofirn rates their turbo at 2,580 lumens, this is just amazing. It’s the first time I see a manufacturer under rate their lumen output this much! Also TA lumen sphere with Maukka calibration gives accurate lumen readings that are lower than most DIY lumen spheres. So I am excited to see a supersized C8F coming.

Considering, what thoughts are shared recently, I would vote for some details as below (and would suggest name alternatives as well):

- Factory emitter dedome would be awesome (add a T letter suffix to the name, if the emitter is dedomed)
- If emitter is not dedomed, I'd prefer these tints: 80CRI 4500K/5000K or 90CRI 4500K/5000K/5700K
- If dedomed, original tint of the emitter may change (it is a guess, not experience, would need some backup), so probably a cooler white emitter would be better then

Edit: factory dedome does not worth it.

SP70-70:
- single XHP70.2
- dual 26650 with 21700 adapters (I hope, this would be a great opportunity for using cells like Samsung 21700-40T)
- reflector diameter would be best in 87-100 mm range
- 12A max current on turbo, 8A as top level of ramping

SP70-50:
- same CCT and CRI, same battery configuration, same reflector as above, but single XHP50.2 instead
- as I remember, if properly heatsinked, that emitter would be capable of fairly high candelas especially, if dedomed
- proportionally, a little bit harder driven, 9A max current on turbo, 6A as top level of ramping
- less output, but more runtime for the same candela numbers

SP70-35F:
- same CCT and CRI, same battery configuration
- this could be the one, which Sofirn has mentioned with multiple XHP35 HD emitter
- this would need a shorter, but larger diameter head design to keep the reflectors for each emitters as separate, as possible




I think, your thoughts about the UI are much preferable.

I would just add these:
- in Group 1, after activating strobe, press and hold could loop additional special modes (1 change per completed 1 second while holding the press, just like changing normal output levels), as someone here voted for additional special modes - I think, that would not be a bad idea, if they are hidden enough
(fast strobe /10Hz or 18Hz/ would be the entry point, followed by SOS signal, 0.5Hz (once per 2s) beacon and 0.2Hz (once per 5s) beacon)
- I'd chose triple click in Group 2 to enter to/exit from momentary on/off mode with the last used output setting. That would be sort of awesome, I think ;)
Edit: Yes, probably blinky modes won't be used too frequently (I accept Sofirn's opinion on this). A momentary on/off could be still handy, though.

Regarding switches, I would choose single side switch or dual side switch. Please, no tail switch for me.



Very much agreed.


P.S.: For the current flashlight development, please ignore a few of my previous posts in this thread, as they were meant for another model, which I would happy to see manufactured by Sofirn.

There is no chance of that because the light has to be in the off position.

We will have to see if Sofirn has room for any extra blinky modes which can be put off to the side and hidden. At this point, it’s a matter of getting the basics right. After that, maybe things can be added.

It is a bit early to be discussing the monster versions. There will probably be a whole new thread for those variations.

Yep… I know exactly what you mean. And totally agree too… :wink:

As a fisherman i don’t actually think tints plays a big part in fog? I know we all have our own views on this but for me a NW tint doesn’t help. My house is rarely foggy but we do get heaps of sea spray and mist and that is a pain to get thru. I think the cold white tints do create more glare in fog but still work just as good as a NW tint. Even at my girlfriends parents place on the lake its always got heavy fog but i still get better throw from a cold white tint.
I have noticed heaps of people live inland on BLF and use there lights in different situations to me which could cause different results. I only use my lights around water/coastal areas.

Thanks for the feedback Jason on your light maybe we can highlight the information so people can reference it for throw numbers.

I personally don’t need 1km of throw in this light i would prefer a more linear beam with good width. Id be happy with the stock reflector size in the SMO variant. People now have heaps of options of XHP70 throwers on the market that they can buy right now so throw isn’t much of an issue.

I dont think we will get any where near 270KCD (1km throw) unless the dome is sliced and the light is running DD.

As for the SP70 itself

  • Custom driver maybe 9+amps or DD ( No amperage numbers indicated as of yet)
  • Two 26650 in series
  • 90mm head diameter
  • SMO reflector
  • Dual switches rear clicky and side switch
  • XHP70.2
  • Multi mode UI with ramping and a second group set with standard modes (e.g low, medium, high)

I think Sofirn is in charge of this thread? But are we going to use the numbers from the K70 build as people in or start a new group buy?

Cool

I don’t have any experience with fog. It’s only what I’ve heard. Maybe it’s just a rumor.

Surely the long range is crucial for spotting other boats and land marks, though. I’m no boater, obviously.

When the time is right, I’m sure a new thread will be started for any group buy. Assuming they do one. They may just give BLF members a discount code. I really dont know. I don’t remember any group buys done by Sofirn.

Just an update, it seems Sofirn has decided to not do any blinky modes on the new UI. It seems it’s not a high demand feature.

On the other hand, they are working on a cool battery level indicator feature. There will be colored leds under the side switch cover.

What’s really cool is the led indicator will also function as a locator to find the light and switch in the dark. Very neat!

When you turn on the main led, the switch leds will stay on for 10 seconds to show battery status, then turn off.

The switch led indicator stays lit when the main led is off, but the tail switch is on. This will make it easy to find in the dark.

The switch led indicator will go off when tail switch power is cut off, obviously.

I have no idea what the parasitic drain might be, but that will be sorted later on. It is influenced by many things that have not been decided on yet. Hopefully you guys like the direction things are going.

That cool :+1:

And I vote for factory dedome to gain some (may be double) throw without excessive large head which not only impractical but also costly for most.

Factory dedoming will rise costs and time per light to make. I think if somebody going for it, can make themself.

Super awesome! :+1: :smiley:

I prefer 2 x 26650 and 3 x XHP 70,2 10000 lumen

I totally agree, dedoming should be a mod done by each individual if they want it.

Also, it cannot be automatically assumed that Sofirn can or could dedome properly.

Sounds like this would be a great light, a heavy duty thrower. Whatever comes out of this, I would prefer either single XHP70.2 light or 4-5x XHP35 HI light. Definitely not another boring XHP70.2. triple flooder.

As for design, here are my two cents:

  • Deeper steel bezel for reflector protection
  • Proper LANYARD HOLE, dont you dare to cheat us lanyard lovers.

Thanks for the update Jason, it’s sounding good!! :+1:

Lot of people can’t do proper dedoming like some of skill moder here it is hit or miss (that mean some new LED cost),factory done may add some cost but surely less than larger the head for the same throw effect.
