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

Commercial Sellers' Spot
2047

I can confirm that the stock SP70 reflector is indeed lightly OP as stated by Sofirn. The L6 OP reflector is noticeably more bumpy. It can be really hard to tell from a picture, but I think I captured it in this photo.

I also noticed that the SMO reflector was 71mm across its inner diameter while the lightly OP is 74mm 75mm across its inner diameter. So the SMO is slightly smaller than necessary.

Using the Sofirn HD 25A cells I found the candela very similar between these two reflectors.

SMO - 192kcd - 876 meters
Light OP - 188kcd - 867 meters

Maybe there is room for improvement in the SMO by making it 74mm and maybe change the height or parabolic shape. I got the same purple dot in the center of the hotspot. I haven’t had time to play with reflector height, yet.

Between these two specific reflectors, Sofirn definitely made the right choice. The lightly OP beam looks great and is still pretty tightly focused. At a distance, the hot spot looks the same as my SMO L6.

The most distance I’ve got out of my L6 with SMO and 19 amps is 830 meters, the SP70 with OP and only 12.3 amps is already beating it.

Here are the new HD 25A battery labels. I wish they looked more different compared to the older 26650 black cells. Maybe a different color.

They performed almost as good as my black Liitokala 5000mah. The Aspire 4300 still has the highest amps. I tested them in my L6 at 5 seconds and at 30 seconds.

Black Liitokala - 16.8A, 16.1A
Aspire 4300 - 19.1A, 18.2A
Sofirn HD 25A - 15.5A, 14.5

So not bad. I still need to do capacity tests.

In testing the current in the SP70 I used Black Liitokala 5000, Aspire 4300 and the Sofirn HD 25A.

I measured at 5 seconds and 30 seconds with a short led cool down in between.

Liitokala - 11.9A, 11.5A
Aspire - 13.0A, 11.5A
Sofirn - 12.3A, 10.8A

So it’s not pulling the big amps like my Lexel built FET driven L6, but it’s still a lot.

I can also see the amps start to steadily decline as the temperatures get hotter. That 10.8 reading would probably be a little higher if the light weren’t so hot due to previous tests.

Jason, something is awry…

2049

Jason,

Thank you for the info. It’s looking like the light and HD batteries are a really good deal. I’m feeling a lot better about Sofirn’s reflector choice too.

2050

Your reflector does appear rougher. Maybe if you duplicate Jason’s photo angle and distance since your photo is quite a bit closer? Who knows…

2051

Nope, from that angle, my reflector looks identical to your picture.

2052

Right, not a light orange peel. And while it does indeed work pretty nicely, it is certainly not the smooth mirror finish they promised in the OP. And the 70.2 doesn’t need any at all, unlike the 70 that came in the L6. I have modified quite a few L6’s with smooth reflectors and upgraded 70.2’s and they are very well received. Even the L2 with smooth reflector and 70.2 is an outstanding thrower with nicely focused beam. So that’s the one thing I wish they’d done here, given us the smooth reflector they said they were going to.

I have the light, it works nicely, but due to this one factor it’s not the light they said they were going to build. It’s really that simple. No orange peel needed. Certainly not this thick heavy OP they’re passing off as light….

Original Post, number one, as stated by Sofirn….

  • UPFDATE 08/14/2018 *

Once again to confirm other information. It’s much appreciated if anyone could help optimize for better reading.

1. size: 9cm big head, aluminum bezel
2. Smooth reflector, AR coated lens
3. LED: one XHP70.2, 5350-5700K emitter
4. 2*26650 long tube(sleeve for 21700),
5. tactical ring
6. Switch: tail forward clicky switch + side switch (with indicator as Q8)
7. Overheating Protection. Low Voltage Protection.

We got neither the AR coated lens nor the smooth reflector. A 74mm reflector opening is a HUGE difference from the quoted 90mm head. So there it is. It is a nice light, but it should have been a Great light.

2053

I think you’ve completely missed several points. I don’t have time to correct all of them.

2054

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.

2057

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…

2058

How does this light compare to Acebeam T27?

2059

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.

2060

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.

2061

It looks like everyone missed post 2000.

2062

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.

2063

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).

2064

I know I posted these earlier, somewhere:

Oops, here, post #1957, and more info: https://budgetlightforum.com/t/-/52135/1957

2065

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.

2066

@Scallywag, can you check if the springs are magnetic?

Thank you.
