I think you’ve completely missed several points. I don’t have time to correct all of them.
I'm actually a big fan of the light, except for the driver/ui. I like my OP reflectors on my 70.2s.
What's strange to me is the SP70 drawing so much less power on turbo.
Has someone gotten the driver out yet? I'm still considering returning it and waiting for the blf special edition, so I don't want to open mine up.

It’s not strange to me. Most all factory FET drivers seem to perform a bit less than BLF drivers. Lexel, Tom E and Texas_Ace, etc… know how to extract the most power. They also use the best components which may not be available in China.
As far as why the SP70 driver is not pulling the same high amps as my L6, who knows. It might be related to the FET it uses or maybe there is extra resistance in the springs. 12A to 13A is nothing to sneeze at and it gets hot pretty quick.
I might swap the FET out with one from MTN E and see what effect it has. Maybe, I don’t know yet.
As for driver pics, Tom E just posted some. Maybe you missed it.
I haven’t missed anything Jason, I know very well what the target was and what we were promised. The only thing I don’t get is why you yourself are so set on glossing over the glaring deficiencies.
You can’t build a light to throw and then scrap the reflector based on white wall shots up close. Glaring rookie mistake. The further it can throw the more a dark spot will show on the wall at close range, that dark spot won’t focus out for at least 10-15’ if the light has really good throw potential coming from a big die like this.
Simple facts learned the hard way, by building hundreds and hundreds of lights.
Please don’t waste any of your time responding, I’d rather you go build something…
How does this light compare to Acebeam T27?
I think, you think, it was built based on the Kronos K70 targets. It was not. This is probably the source of your confusion.
Hang on, you didn’t even read what I said. Plus you also make assumptions about the distance.
For the record, one more time, this light was not built for maximum throw. If it was, we would have put an xhp35 hi in it. This is basically designed to be a factory hot rod version of the S70/L6. Higher output, better UI, more throw (not maximum) all from the factory, no modding necessary. Plus at an affordable price. We have met all these goals.
Jason, Dale...I don't mean to interrupt the little disagreement of yours but maybe we all can acknowledge and agree that the SP70 is Sofirn's first (successful) attempt to build a big XHP70.2 light. Thus, their experience might evolve in time when they develop the BLF edition that hopefully fulfills all of our highest expectations such as a big leap in terms of throw and more efficient components (e.g. Infineon FET, SMO reflector, dedomed XHP70.2, BeCu springs, AR coated glass, and so on...). I could also imagine Lexel to invent a nice buckdriver for the SP70 for a more regulated output. Personally, I was in hope Sofirn would have spent more time for testing the SMO reflector and the optimum alignment of the emitter to reduce tint shift and rings in the spill. Maybe this can be done with the BLF edition. For the discounted price of $ 50 or € 50 it's still a very decent result we now get to buy.
It looks like everyone missed post 2000.
I'd love to see anduril or narsilm on this.
Jason, thanks. I thought I remembered seeing some, but didn't know if I was getting it confused with other lights. Nice to see the switch is a separate pcb, and not attached to the driver as some lights do. Would be easy enough to swap something Lexel builds into it.
Also, for the led color temperature, the Cree Fried Egg™ is strong enough in the corona that I don't notice how cool the cct is unless I'm really paying attention to the spill.
These 2 remarks, made right next to each other, sound conflicting to me.
How can you tell that Sofirn made the right choice of reflector if you did not check yet if they did the focussing right on the smooth reflector, especially if both you and Sofirn found a hole in the center of the beam while we know here on BLF that the XHP70.2 makes a fine hotspot in a smooth reflector.
I do not think that a non-parabolic reflector can be a reason, never heard of any manufacturer making non-parabolic reflectors, there is no reason to do that other than screwing up CNC settings.
This is in no way an attempt to dismiss Sofirn’s first big thrower, I think that the SP70 does many things right, and the good price more than makes up for the shortcomings that it still has (finning could be more effective, reflector deeper and smooth, a real BLF-UI would be more attractive).
I know I posted these earlier, somewhere:
Oops, here, post #1957, and more info: https://budgetlightforum.com/t/-/52135/1957
Yes, Jason also linked it. Thank you both.
I forgot to reply to this part. Yes, 12A is nothing to sneeze at, and we're looking at something like 90 watts there. Although I'd disagree that it heats quickly. Between the power reduction of possibly up to 50% as well as what we're hoping to be better thermal mass, my SP70 is not a hand warmer like my L6 is.
I'm really excited to see your efforts with a new FET and Tom's efforts with an ATTiny. I just need to decide if I want to mod it, or if I trust Sofirn enough to get the BLF edition right. Well, not even right, because many would probably prefer slightly different features than me.
Other notes:
I just noticed the tactical ring thing by the tail spins freely. Weird!
My dual springs appear to be compressed enough to both make contact with Shockli 5500mAh button-tops.
The tactical ring is not threaded, it’s held in place by sitting on o-rings.
The way Sofirn explained it to me was that they could not play with the reflector height because the centering rings had already been made and having a new batch made would have created a big delay. So they had to chose an ugly beam or a pretty beam.
If adjusting the reflector height makes for a nice looking hot spot, then Sofirn probably has the time to have new centering rings made. I also hope they can make the SMO reflector the full 75 millimeter inner diameter. There needs to be a noticeable jump in distance between the two or what’s the point of the SMO.
I can actually think of a reason to use a non parabolic reflector shape. Since the parabola is based on a single point source, I can see were a really large emitter like the 70.2 might cause some anomolies. I’ll use the picture below.
Notice how a large emitter could potentially create anomolies in the hot spot? A very slight alteration in the reflector shape might eliminate the anomaly. If it does, why not incorporate that tweak to the shape?
Or maybe a parabola is fine, but this particular one is not focused properly? IDK.
My Lumintop Tool AA also has a colored spot in the center of the hot spot, but it’s yellow instead of purple.
Certain things are really strange to me. Like why is the SP70 SMO spot purple? Where is that color coming from? It’s beyond my understanding.
That the led is not a point source does produce imperfect imaging, but that does not make a difference, the parabola will still be the best shape for producing throw. No magic possible here.
I do hope that Sofirn can sort out the smooth reflector, indeed full size and well-focused.
My 2 cents, for what it’s worth (probably less than 2 cents 
)
I, for one, greatly appreciate Jason’s efforts in bringing a new light to market, that performs pretty darn well. Let’s be honest, anyone on Amazon that is not a flashlight enthusiast is going to be blown away by the performance. As well as many of our fellow constituents who already enjoy the light.
What I dislike is the manufacturer’s willingness to push a product onto the market before it’s perfected. We keep seeing this with other manufacturers where a design is made, a few prototypes are sent out, and before the prototypes get in the hands of enthusiasts, its already on Amazon (or pretty darn close.) Astrolux and Amutorch just did a similar thing of having a group buy before the lights were even made! I think Sofrin jumped the gun on this one. While it’s a great flashlight, it could have been a fantastic light with a little more tweaking (reflector design while using the same head, better UI, higher quality driver components)
Sofrin, I will not be buying a light until I see a dedicated BLF edition which remedies the reflector design, and utilizes a better user interface. Single click ON to the last setting used (which is usually high) is a huge factor. I would be willing to pay a premium price to get the light I (we) like.
Hopefully we can keep the conversation going, constructively and objectively, because I would love to see a light that really achieves the objectives which were originally set forth.
Just to be clear, it does do this. (In case you thought it didn’t and needed to be added)
Does or does not? I thought Tom E said it goes to last used?
If my info is incorrect, I’ll happily correct it. I thought it went to last intensity used in ramping mode.
Edit: as I understood it, from OFF, press and hold goes to moonlight, and it will not ramp up to high like Narsil or Emisar’s UI. The only way to get out of moonlight is to turn it off, then single click ON which goes to the last used setting. For me, that seems like a shortcoming.
