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

I should be getting my SP70 in the next few days. They couldn’t send it express because it’s got batteries. I think they are the HD batteries plus they sent the SMO reflector. So I’ll be testing all these soon.

SMO reflector Is it going to be an option too? If so, I’m gonna wait on my purchase until I see your test although the original photo of the SMO beamshot was a bit ringy. At this point I will probably just stick with the stock OP reflector but your review will be interesting nonetheless.

I hope the HD batteries turn out decent. I already bought some from the Aliexpress Sofirn store along with a few C8T lights - received them in California in less than 2 weeks. Pretty fast shipping and comparable to regular Amazon shipping times.

I think they sent the Prototype SMO reflector that they used for testing.

When my 26650s arrive, I will do a comparison with my L6 as well.

I'm happy with everything except the tail switch function. I think I may need to mod it because of this...

Has anyone had the side switch apart yet? If not, I'll get to it eventually.

Decent SP70 video with beamshots:

I just ordered mine from US amazon.BTW, Thank you for the code…chiming in to say I have my hand up for a smo reflecter as-well :slight_smile:

I remember back when I got the L6 it was said that 2 cells in series must both be protected

So butting up 2 unprotected 26650s is now ok with this SP70?

Yes.

Just rotate the cells on every charge cycle for equal wear.

My SP70 seems to heat slower on turbo than my L6. I also can't really visually tell when/if it steps down.

That was bogus then just as it is now. Protected cells are for newbies who do not check cell voltage before charging or capacity after recharging.

If you are a more experienced user, you will check these things to make sure both cells are healthy. You also want to marry the cells so they are always used together. This allows them to wear at the same rate.

Once you get above 10A or so most protected cells will not even give full output to might trip the protection circuit. Some protected cells just limit all current to 10A. So unprotected high drain is what you need for the highest amperage and output.

BTW, the stock L6 is limited to about 5A-6A so protected cells work just fine.

There is no need for this. You are thinking the cell closest to the head gets warmer?

Once you recharge the cells you put them back in randomly, right?

Stock or modded L6? The SP70 was designed to heat up slower due to the extra mass.

The amps seem to drop slowly as it gets really hot. I don’t think it does a sudden drop. I need to do more testing.

Yes.

In a series setup, the cell closest to the head generation will get slightly hotter.

Swapping the cells when putting them back in can help with small capacity degradation.

Thanks for the clarification guys!

In my sig, fet+1 and XHP70.2

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…

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.

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…

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