[Canceled] Sofirn SP70 BLF Edition

[Scallywag]

@4492011

Interested, in max throw with a fair amount of lumins so not a flat white, don’t really like the throw from L6 and 70.2 looking at most of the throwers they are built around XHP 35 however they decide to get there.

You may wish to have a peek at a 21700, XHP35-HI thrower Sofirn has upcoming in another thread: Sofirn C8G

For multi-cell XHP35 HI lights, Astrolux MF02, Astrolux MF04, and BLF GT (also GT70, using XHP70.2).

I know it’s definitely the case in Germany

You are right, but not only in germany :

Those british definitely were bad influences : imperial system, dot instead of a coma, etc.

So how do they interpret whether 4,885 (four thousand eight hundred eighty-five), which is read as 4.885, is actually 4.885 (four and eight hundred eighty-five thousandths)?

488.555 would be even more confusing

Is having 1s or 2s battery configurations with extended tube like Convoy L2 is out of the question?

[BlueSwordM]

Yes, out of the question.

@Lux-perpetua: I like to follow this thread but you make it difficult by keeping editing the second and third post. Clicking the “new replies” always brings me to the edited 2nd and 3rd post, and after that I have to search manually for the first new posts in the thread. Editing the original post does not affect “new replies”, moving the content of #2 and #3 to the OP makes it easier, clicking on the “new replies” then actually gets you to the new replies.

Sorry Jos, I was not aware of this issue. I moved everything from post #2 and #3 to the OP. Hopefully, this will resolve any future problems with new posts.

@DB Custom

Lux-Perpetua, I notice that you like to use a decimal point in the tint descriptor… the problem with this is that the K is not for thousands but for Kelvin, so your 4.885K actually would mean less than 5 Kelvin and THAT would be atrocious! 4885K is an actual temperature of light that we would like to see, based on the Kelvin temperature scale. Thank you, that little detail was bugging me.

Sorry Dale, I didn’t expect to cause that much confusion when talking about CCT and Kelvin as the base unit. However, I do agree with you that using points and commas as decimal separator can sometimes be confusing. ;-)

@oweban

A lot of Europe uses a punkt for a thousands separator and a komma for decimals - so natively to them, 4.885 is what we’d read as 4,885, and they’d say “3,0GHz CPU” when we’d choose 3.0. I know it’s definitely the case in Germany Ich spreche nur ein bisschen Deutsch.

That‘s exactly the root cause. I‘m used to separate the decimals by a point, not by a comma. That reminds me asking the cocky question what the internationally agreed standard is. Point or comma? :-D

@DB Custom

Right, and I reckon we all pretty much know that… I tend to stumble on stuff like that because I take things literally, that fine line between black and white, right and wrong. I have never been good at reading between the lines. I got it, after looking at it a few times, so I guess everyone else will too. If Lux Perpetua ever asks me to build him a light I’ll try to source 4.885 Kelvin emitters… Edit: Oh NO! I get it now! I’ve been PUNKT! :person_facepalming:

Haha...I‘d love to get a DB Custom 'one of a kind' with 4,885...sorry, 4.885K. :-P

I just wonder if my eyes would even notice a CCT that low. :-D

Dale, from this day forward I promise to keep in mind using no decimal separator anymore. Result: No confusion for anyone. How’s that? :-D

[DB_Custom (Dale)]

LOL, do what ya gotta do man, I’m stuck in the dark ages… will figure it all out sooner or later.

[Lux-Perpetua]

Dale, you got quite some light for someone who‘s stuck in the dark ages. :-D

Cheers, Thomas

So is it possible this special edition may come out in 2019? seems like it’s still pretty early stages?

[Barry0892]

I think it will come out in 2019 no matter it’s a SP70 BLF version or a compeletely new light if only you guys reach an agreement soon.

[WTF]

“retaining ring, smooth reflector, different tint, no switch tail cap, Anduril firmware”

This was Barry’s list from the other thread, it looks good to me.

Not sure how much time Toykeeper has available to get the configuration files right with the lantern and FW3A on the go.

Meanwhile the version of Narsil Tom E has in his MT07 is proven and probably perfect for this light.

Dale mentioned going to thicker glass to prevent cracking.

Is the plan to reshape the existing reflector and give it a smooth coating?

Maybe find an existing reflector and change the front of the head to match.

This looks interesting, wonder where Ban found it. http://kaidomain.com/Flashlight-DIY-and-Tools/Reflectors/S022485-86_2mm-D-x-84_7mm-H-SMO-Reflector

Not sure if Sofirn is willing to do that. I’d pay $10-$20 extra for thicker glass and a bigger reflector, would anyone else?

[oweban]

Okay so are we thinking wider or deeper reflector? Both would require re-machining of the head piece of the body…

70.2 is just sticking with “wall of light”, right?

[JasonWW]

I really don’t think Sofirn wants to make the head larger or longer.

The reflector is usually made for a specific head. It’s highly unlikely a different reflector would work in the SP70 head.

I think they want to stay with the 70.2, as well. A 50.2 would not handle the amps and it would be weaker.

I would not call the SP70 a flooded or wall of light nor a thrower. It’s like a general use light. A good mix of flood and throw.

I don’t think a sliced 70.2 is an option either for the reasons already listed.

So a different tint is the most likely change to the led.

[Nicolaas]

My 2 cents on this?

2 x 21700 with a 26x10 connector would be great, otherwise just stick to the 2 x 26650 version.
XHP 70.2 shaved (otherwise throw is garbage), still more then enough lumens output.
Clear reflector (again, throw)
SS bezel.
Thick coated glass lens
Good UI

And - PLEASE - NO glue, nowhere any kind of glue.

If glued: No God, NO!

Cheers,

Springs? Will they make much difference? What about a spring bypass? I would definitely prefer a nicer tint, I’m hoping a smooth reflector will extend the reach. My only concern is will it make the hotspot smaller?

Bypass springs, gain 1000 lumen according to someone who did it.

The hot spot does not get smaller, but the corona may.

[Scallywag]

Springs need to be bypassed or GOOD BeCu double springs.

I would not like a sliced LED. I'm fine with a good SMO reflector, but they need to get the inner diameter to match the OP reflector.

To be honest, there's two things I hate about my SP70 and I love everything else.

• I hate the UI/driver, and moreover I hate the lack of retaining ring.
  • This is so annoying because I'm not confident I can make a replacement driver fit.
• I hate the crappy steel springs. I finally checked, and mine are strongly magnetic. My Olight S1 can hold the entire tailcap by the spring.
  • This is an easy fix though, I can bypass or swap for my Blue springs.

Personally, I'd want to keep the tail switch, but have it only be a lockout function. That's probably just me, though.

[Relampago]

I like the tail switch too, and I miss the strobe function. I was using the SP70 last night and I love the amount of light it puts out but I found myself reaching for the SP33 because it was easier to carry. Tonight I’ll take the SP70 to a darker environment and see how it performs against my TC500. I’ll post some shots from last night. I actually use the strobe because we encounter psychos at night and its a quick diffuser of tense situations. Makes the meth heads think twice.

Looks like you might be using auto camera settings. I could be wrong, but if so, it makes it hard to distinguish anything other than the shape of the beam. Relative brightness and tint get corrected a bunch with auto
