Everybody, Sofirn messaged me recently and they said that the springs are indeed gold plated dual BeCu springs. They also thanked me for the advice :)

 

Awesome. I'd like to thank you as well Silly

It does look like it suffers from your reflector pet peeves. Thick bezel and you can see the entire edge of the reflector from the front. If that 90 is measured from the outside of the head it's much less ID.

Well maximizing reflector ID is for max throw - a 70 LED and OP kind of kills that idea, but it does look like an oversized bezel, Facepalm

Another good reason to like SS bezels - generally they are made thin to keep costs down, and also since they are stronger.

What’s gonna be the optimum cells to use for this light? Brand? etc?

Ahhh, looks to me like they are including 18650 adapter sleeves, not for 21700's. For 21700's, the tubes and spring would have to be set up properly to go between short 26650/18650'a and 21700's and that gets tricky because you double the variance. It's probably a boost regulated so not sure if high performance cells well get you much, accept possibly longer regulated output times.

Not much info, so dunno for sure, but this my my guess.

It’s a FET driver but until someone measures how much the springs compress and how much room there is idk how you could for sure recommend something. If they tested with 18650 button tops in series any high drain 26650 button top (non protected) should fit. For 21700’s to really work without over compressing I’m betting a solder blobbed flat top works best since you probably wont have much room to spare for true button tops. They are hard to find in 21700 anyways (non protected)

Its using a Fet on direct drive on the highest output Sofirn got almost 7000 lumens with okay cells from the SP70. I would personally just use 26650s makes the most sense its made to use 26650s they should give best performance and run times.

Ahh, ok - I got confused there, and missed something. Must have been earlier in this thread about the FET based driver.

Interesting if they got ~7000 lumens and list it at 5500 - wut? A manufacturer under spec a light? No....

I think the 5500 lumen figure is old when they where using standard non high drain cells.

I'm all discombobulated over the specs. Since I don't think Sofirn could do it, we need one post somewhere that summarizes the details. Looks like Lux-Perpetua has the inside contact, so maybe post #4 could be edited up to reflect the current status as we understand it?

Just an idea....Hhhmm, ok reading more on this, wow - the UI is very close to NarsilM/Anduril - I like it!

-> single click ON/OFF, press&hold to change modes/ramp, dbl click for turbo, 4 clicks for lockout. I like you can turn the light ON/OFF from the side switch, and not only the tail, but they call it being in STANDBY - wonder what the parasitic drain will be then.

Their reasoning was they made the specs according to what someone would expect if they bought the “kit” that included batteries. Their included batteries at the time happened to be pretty mediocre. Between possibly using better springs and possibly sourcing better batteries they may need to update that number to whatever it measures with the latest “kit”

Yea the specs are all over the place. The only major change we had was for the slight OP reflector instead of the SMO. Maybe they will still make a SMO who knows.

Also i dont know if they have confirmed what LED bin/tint they are using we had some talk about it.

I would like to see a group buy started with a discounted price for BLF members. I think we could get a few hundred members on board.

Sofirn’s 4000mah 21700 flat top cells fit, but just barely. The springs are fully compressed. So they are not officially recommending them. I imagine some brands will fit and some won’t.

Also, they said for their SP70 manual they would probably list the specs using their own 26650 battery. These are not high drain cells. They are closer to, or even less than, the performance of Panasonic 3500 GA cells. I think it would be a disservice to list such low official specs, but they have their reasons.

We use sofirn 26650 output data in the manual to reduce misunderstanding and bad feedback. Because we are going to sell bundle “SP70 with 26650 batteries” which will be chosen by common buyers. I don’t wanna receive bad reviews because the data is less than manual with 21700 output data.

For BLFers, most of them know HD batteries give better output. Hence it won’t be an issue.

I insisted on these points as I find them important.

We have not found out the parasitic drain. No one outside of Sofirn has tested the light yet. I can only hope it’s low. The S70S was quite high, but at least there is the tail switch to cut all power when storing it.

Wow, this turned to be a real BLF special, not just a slightly better S70S, as the original K70 was intended. I'm very impressed how Sofirn listened to us on this one. I know it's taken time, but look'n at the performance and UI, seems like a winner, best 2 26650 cell stock light out there.

Details I'd be concerned about are PWM rates, parasitic drain, efficiency, etc. If this is a somewhat new FET design, not sure if they have lower output secondary channels, etc., like we do in our BLF drivers. Not sure if anyone knows this stuff yet, or again, I'm just missing it.

A lot of time was also spent designing it for good heat dissapation.

Unfortunately, we don’t have real specific details on the driver design. I don’t think the average buyer needs those details, but I know certain BLF members want to know. The problem is I’m communicating through Tracey and it’s very hard for her to translate this information to and from their engineers.

I was really hoping we would get a sample light to run through its paces, get real specs, get driver pictures, beam shots, inspect for any issues, etc… but I’m not sure that will happen.

This isn’t really a true BLF light (like someone here designing the driver), it’s more a Sofirn light with BLF influence and suggestions.

Well, at least they are listing it as the "BLF SP70" for now, and like you said, there's a lot of BLF influence. Yea, sure would have been nice to get a sample or two out there...

I think they were supposed to call it the Sofirn SP70 – BLF Edition. Not the Sofirn BLF SP70.

Is there going to be a group buy or is the annaversary going to be the lowest price?

Edit- I re-read the OP. Facepalm

The last I heard is that the BLF price would be much lower than $72, but I’m still waiting to see what Sofirn has decided.

I also don’t know how they would give certain people the discount price. Aliexpress and Amazon does not use coupon codes, afaik. It might be similar to the Sofirn Q8 where you put it in your cart then contact them with a “code word” to get the discount price. I’m sure they will say once they have it all worked out.

It is still a ways from actually shipping.

I ordered mine earlier today - $61 after the anniversary discount, added a Q8 holster to bump it over $65, then took the $6 store coupon wink.

Yes, and their High Drain 25A batteries are here. Pictures are not ready so it shows the older black ones. The HD are button top.

So $56 for SP70 with anniversary discount and $6 coupon, I wonder if BLF price will beat this?

I am guessing we where aiming for around $50 USD. I have no idea what Sofirn wants to make on it.

If you buy it at this price its $10 USD more than the Q8 group buy price. From the factory it should be at least 2000 lumens brighter.

Hey BLFers,

Sofirn SP70 on aliexpress You can preorder on aliexpress now, the sale price is US $61.59 for flashlight alone, but you add it into cart, leave a note of your BLF ID, we will lower the price to USD$50. Orders will be shipped as soon as possilbe!

NOTE:

1. the light is supposed to has 2 versions: one is sofirn SP70 for muggles, the other is sofirn SP70 – BLF Edition for flasholics. Sofirn SP70 is released first

2. the light officially gives out 5500LM via normal 5500mAh 26650 batteries, while it gives almost 7000LM via HD 26650 batteries and more than 7000LM via 21700 batteries, you need to purchase the batteries seperately.

3. sofirn officailly suggest 5500mAh 26650 batteries for muggles. While flasholics can choose to use HD 26650 batteries which fit nicely, and 2* 21700 batteries can fit but really really tight, not good for the batteries and springs.

4. For those who are located in USA and Germany, we suggest you wait for amazon availability, same price and faster shipping.

5. A sample of Sofirn SP70 will be sent to Jason when the first batch is fulfilled. Then we can talk about a real BLF Edition. Maybe use smooth reflector, add retaining ring or move a bigger step forward for more leds and more powerful etc. It’s possible but not sure.

Thank you for your patience!

Great news, Sofirn!

Hope the HD 26650 batteries are FBA too!

When I'm spending on¥ foolishly, I like to do it i$el¥...

I have all the flashlights I need, but not as many as I want...
