Ha ha, you said “slightly”.

If the single 70.2 version can reach 1000m, that is double the throw distance. Even my current L6 which has only about 75% more throw and 90% more lumens than stock is a night and day difference. Absolutely no comparison.

The parts alone to build my L6 was about $50 on top of the $65 light. That’s $115, plus you then have to physically do all the swapping over of components.

The SP70 should be like a factory version of this, but sold at well below $115. Plus not everyone can do all those mods, so a factory light with all these upgrades is much more appealing. It would be a HUGE upgrade over the L6 and S70s.

I dont like the idea of a dual emitter type, please make the SP70 the L6 or S70s from 2018 and it will be a hit.

Seems we are clear about the UI, brightness levels(It’s confirmed that 5000LM can be made with high current.).

The name would be better be Sofirn SP70 and we can mark “helped by BLFers” on the package box and manual?

Do you guys have any ideas about the looking? the fins, the knurling, the cap etc. Example as reference will be much appreciated. Our designer’s brain is going to explode since several

new lights need to be designed this month. Facepalm

The stopped K70 project has pretty nice design. Especially for tube and tailcap.

This sounds good. I think if the engineers made it only do 3500 lumen, people would be disappointed.

Sounds good, maybe even “Sofirn SP70 – BLF Edition”

I am not good at designing styles at all. We may need to look at several other current designs.

As far as head shape, I modified an image that shows the curved L6 shape on the top and S70/K70 shape on the bottom.

I prefer the curved upper shape because I hold my light by the head and raise it to shoulder level when using. I don’t ever hold it by the battery tube. Plus I think the curved shape looks better than the blocky lower shape.

I also prefer a streamlined tail cap on the L6 and S70 instead of the oversized, bulging tail cap on the Kronos K70 design.

I like that battery tube criss cross diamond pattern as well. Not so much the bulged out tail cap. Do people like the bulged tail cap?

Yes, the upper shape is better for sure, if they could remove that flat area from the reflector and make the body thicker at that point it would be basically as good as it can get thermally. The lowest fins could be slightly deeper but it is debatable how much it would help and too deep would hurt.

Could also add 1 more fin at the bottom as well.

My taste is a mixture. I like the more square look of the K70 but not the chunky tailcap, instead I really like the ‘tactical ring’ on the tail end of the L6. I really dislike the multitude of cut-outs of the L6 everywhere and in six different styles, and I dislike its crenelated bezel. I really the clean lines of the head of my LuckySun F3X (not the rest) and I’m a s*cker for SS bezels.

Btw, my L6 with smooth reflector, simple resistor mod and 80CRI 4000K XHP70.2 does 103 kcd (at 4500lm), but what is the throw of a stock L6? I searched BLF and all I get is ‘decent throw’ and ‘good throw for the size” and such, but no actual number.

Jos, i agree !

  • Please make it a nice small stainless steel Foybezel ™ like the K70.
  • Cutouts, please without all the extensive cutouts like the L6 has, (the reason i have the L6 because it was cheap, but i prefer the clean lines like the S70s has) For me it would be perfect with the curvature of the BLF/Kronos X5/X6
  • Tactical ring, please make it optional, so standard a clean ring with the additional tactical ring
  • Tailcap, should not be bulgy.

I like Kawiboy’s cleaned up L2, but as said, the finning should not have all the cutouts.

Personally I do not like perfectly smooth bezels at all, it is impossible to see if the light it on when put face down and I have forgotten they were on in more then one occasion.

To be honest I like the look of mild crenelations better myself as well but to each their own.

Stock throw of the L6 is about 450 meters. (3150 lumen)
Stock throw of the S70 is about 480 meters. (3500 lumen)

I like sleek (think M*g), so the less it looks like a random assortment of plumbing parts, the better.

Smooth, but maybe 4 small notches (as if to fit a bezel-remover tool) would let light leak out in strategic places.

Think of a VG10/SF36/etc., only not as wide.

That’s hilarious! (But true, i agree)

I can live with the BLF Q8 style bezel though

Had to go look it up to remind myself what it looks like, but yeah, that’s nicely done. Doesn’t look overly medieval.

Thanks, so mine is about double that with the mods (and a bit more if a cool low CRI led was used)
Hmm, contemplating shaving the led…

5000 LM is fine but even higher would be nice too if possible. Even your C8F measures 3,500 lumens with a TA lumen tube. Maybe your 3x emitter version can output more. Would you be able to release clear anodized version of this host/flashlight like the L6?

I like the idea of getting rid of the scallops thru the cooling fins, the S70 looks too much like the X6 Hunter.

As far as a smooth bezel, wouldn’t the lighted e-switch tell you if you left the light on/off? You could also make the bezel with small scallops in it….an extremely less aggressive crenelated bezel? Innocent

I do like both the smooth black and the polished stainless smooth bezel, but on a totally blacked out light, it adds just a touch of bling to it!

It might be stupid but I personally found that with different battery C8F can give different lumens. From what we tested is about max 2500LM but you guys get 3500LM from C8F. What is the trick?

I think most of us measure output with battery freshly charged to 4.2V. You have fet driver in the C8F and if the battery is even 3.9V you can measure lower numbers. In my measurement tables all the numbers measured right after power on and jump to turbo. Some people measuring it after 30 seconds but as the light heats up and battery sags voltage that numbers also lower than measuring at start.

And the battery is very important. I use barely used samsung 30Q-s and LG HG2-s for measuring.

Freshly charged Sony VTC5D. Maybe I got a cream of the crop C8F with the best emitters in its bin.

Okay cool we are here to help Big Smile

Once we get some idea of the specs we will start a new thread for a group buy.

As for price we will aim to please all! Make us an offer and we can discuss it in the group.
Say you want us to move 500-1000+ lights for this group buy make an offer based on the specs and that amount of sales that are expected? Plus any additional parts we can work out a new price if needed.

You may have to send a prototype to a BLF member to check if its okay and up to standard not sure where that falls with cost (who pays)?

Also will you be selling the light through a 3rd party vendor or your aliexpress store?

Will you stock spare parts? Is it possible to make an OP style reflector that will fit if we get enough interest?

As for the name we can have a discussion here in the thread. I like the BLF70 maybe even BLF70SP i am not that creative so some one else will have a better idea.

Also i am with every one if we have a hidden strobe it should be a triple click to access from the standard group set.

Now i will see what every one else in the thread thinks? Does this sound okay lads?

That’s very nice! Thank you! (and sorry I get back to your reply late. So much information to deal with…)

Now we are kind of cool with UI, brightness levels. And we will send to confirm later.

The looking design is supposed to start next week. Hence we can talk about it this week.

More than 500-1000 lights would be helpful to keep it budget.

No problem to send prototype to one of you guys to test first. We send via DHL or UPS which is more expensive but faster. Big Smile

To make sure the price is as good as possible, we would choose selling the light through our aliexpress store.

It’s not a problem to stock any parts if we get enough interest.

About the name, Sofirn SP70 – BLF Edition would be great. Thanks @JasonWW

UI, levels, Size, design, price. Did we miss something?

I don’t know what it feels like, but it has a nice look to it. It seems pretty much the same as the L6 tube knurling.

I like the L6 knurling look and feel so I think the Q8 knurling will be just fine for the SP70. Big Smile

Ps, maybe it can use the same threads as the L6 and L2 so the battery tubes can interchange. People already have short L2 tubes. It’s not necessary to have matching threads, but just a thought.

If they use a good FET, bypassed springs and good batteries I would imagine 6000+ lumen, but it’s best to be conservative and aim for 5000 lumen.

The triple version I would estimate at double the output. Maybe more, depending on batteries and such. It may require very high drain 26650.
