Convoy made XHP70.2 version L6 with SMO reflector on Aliexpress. I think driver is the same or a little boosted. Factory claims 4300 lumens. I hope this SP70 will be much brighter

The SP70 is using a FET driver, so…
Sofirn already measured over 7,000 lumen with some good batteries.

Sounds pretty darn good….. Thumbs Up

Wish convoy was building this light, we would have tint choices up the wazoo! Anything over 5k is poop, 4k perfect. My sofirn Q8 is great for showing off, the oringin BLFQ8 is far superior in tint and real useage. Any humidity in the air renders the Sofirn Q8 as useless.
This (your second post in this thread) is nothing more than your opinion & preference.
Here is mine…. 4000K sux. Most anything under 4700K is pure crap…
……..yeah pure crap, as far as I am concerned.
And again, this is nothing more than my preference & opinion.

But the CCT of this light was decided months ago to be between 5350K & 5700K.
To gripe & whine about that now is nothing less than stupid.

And the builder of this light, Sofirn; was decided from the start.
To gripe & whine about that now is worse than stupid.

Don’t like it, don’t buy it. Plenty of people will……

Merry Christmas…… Thumbs Up


I would just say to swap in whatever tint you want. If your very particular about tints, then this is probably a common mod to do. The L6 uses the xhp70, btw. Most folks might end up swapping it for a xhp70.2, anyway. Assuming they want higher output, of course.

I thought everyone knew this was a FET driver. Maybe some people are just joining the thread?

The driver and tail spring is supposed to be BlueSwordM’s beryllium copper spring for high conductance. No bypass needed there. I believe they are double springs. This is something BSM arranged with Sofirn, so I don’t know all the details.

Jason, does this pretty much sum up what the Sofirn SP70 will be as far as we know at this point??
…….

SOFIRN SP70

  • 1. size: 9cm big head, aluminum bezel
  • 2. Smooth or Very Mild OP reflector, AR coated lens
  • 3. LED: one XHP70.2, 5350-5700K emitter
  • 4. 2 × 26650 long tube /(sleeve for 18650), 21700 not supported
  • 5. tactical ring
  • 6. Switch: tail forward clicky switch + side switch (with indicator as Q8)
  • 7. FET Driver
  • 8. Overheating Protection. Low Voltage Protection.
  • 9. Tail switch to power on / cut off
  • 10. UI:
    Group 1 ( default )
  • When the light is on(the indicator on for 5s to show the battery power), press and hold the side switch, the brightness levels circle through low(50LM)-Med1(300LM)-Med2(1000LM)-High(3000LM), double click to Turbo(5000+LM), when encounter the brightness you need, release the side switch. Single click to Standby(the main led is off and the indicator is on), click again to turn on the main led. When on Standby, click the tail switch to cut off (indicator is off ), click tail switch again back to Standby, click side switch to turn on the main led. When the main led is on and you click the tail switch to cut off, click tail switch back on goes to the remembered brightness levels.
  • Group2 (Ramping)
  • When the light is on, long press to ramp, 2LM-5000+LM(150 levels, ramp from lowest to highest in 3 seconds, blink to remind reaching lowest or highest). Ramp again within 1.5s, reverse direction. Ramp again after 1.5s, keep the direction(same as Q8). Click to turn off the main led (Standby)

When the light is on or on Standby,double click to Turbo(5000+LM), click back to previous brightness or Standby.

  • When on Standby, long press(1s) to Moonlight(2LM), click back to Standby.
  • When on Standby, 4 fast clicks to lock out, another 4 click to activate.
  • When on Standby, 6 fast clicks to convert group, 2 blinks to confirm.
  • When on Standby, 8 fast clicks to Beacon (Lights up at 1000LM for half a second, pauses for 2 seconds, then repeats.) click goes back.

Indicator:

  • 1.When light turn on, the indicator led shows Green or Orange or Red for 5 seconds to show power status. If the power is running out, indicator fast strobe in Red continuously.
  • 2.When in Standby, the led is Green as locator in the dark. Click tail switch to cut off.

I think all your info is from 8-13. Some newer updates are:

The reflector will be slightly OP. Close to SMO.

The sleeves might be for 18650 as 21700 is not officially supported. I’m not sure on the sleeve size.

I have not heard of any changes to the UI recently. I assume it’s all correct. We won’t know for sure until a prototype light gets tested and all the functions are verified.

Yeah, most of it was from the 14 August Update in post 1. I added the possibility of a ‘Very Mild OP Reflector’ & the FET Driver.

I have now updated the reflector & battery sleeve as you indicated. Thumbs Up

I just thought it might be handy for anyone just recently joining the thread to be able to see the summary of what was going on with the SP70.

Thanks & Merry Christmas!! Innocent

Adelina (Sofirn) told me 21700 would fit but are not recommended. So, they are not officially supported but they might actually work eventually. I assume springs will become fully compressed with 2x 21700 and a small neodym magnet in between. I have no idea if that would be harmful to the flashlight or its batteries, though.

 

Merry Christmas to everyone!

I extend the battery tubes on Convoy L6 and Jaxman X6 lights with these…http://www.ebay.com/itm/10pcs-26×32×2mm-Copper-Flat-Washer-Spacer-Gask... when I want to run my 21700/20700 in them. I ream out a couple26650/18650 plastic converter tubes to fit snug and slightly solder blob or of lately stamp .500-.750mm copper slugs out of copper sheet using a Precision brand shim punch to make the anode contacts and solder them on for my dedicated 2×26650 lights…..yeah yeah I know copper oxidizes, I do not care, I have cleaned/polished and lightly coated (all copper components) with No-OX-ID special “A” and had no issues, ever, but that is what I do..ymmv…

Can’t wait for this light. NW tint is good news. Best place to buy 21700 to 26650 sleeves?

This depends. Can you add solder blobs or do you need batteries that already has a raised positive end?

Those are bit harder to find locally.

The Aspire 4300 from IMR makes contact in series. It’s a good cell. It pulls 19 amps on my L6.

Then there is the Basen 4500 from Liion Wholesale. I haven’t tried it, but I believe it’s a good cell.

There is the Evva Tech 4500 from MTN.

Maybe someone knows of another?

The top 3 pictures look like some type freezer unit at -35C

Bottom 2 pictures are power supplies, integrated sphere, & measuring devices.

That’s my story & I’m sticking to it……. Big Smile

Thank you & hope your Christmas was MERRY also!! Smile

I don’t know much about it either. I sent a link to Maukka. Maybe he can tell us more about the HP8000Z.

I think it has to wait after Chinese New Year Vacation…

We are thinking about the SP70 Pro: XHP35 HI in the middle for more throw, several XHP35 or XHP50.2 surround the XHP35 HI for more power, maybe 15000LM

How is that? The challenge will the very high current.

By the way, we found high discharge 26650 cells: 4800mAh, max 24A current. Now Under test in SP70.

I can wait but what about single XHP35 HI version for real thrower drive it to 2-2.5A that easier before go to multi LED

I’m guessing you mean they are 24A continous?

SP70 Pro sounds nice and the idea of an XHP35/XHP50.2 array sounds much more useful than Acebeam's X70 which is just another extreme bright floodlight with questionable range. However, looking at the actual reflector size of the SP70 it might be challenging to align several XHP emitters around the center LED without negative effects on the throw. I'm afraid it could lead to some cannibalization effect, i.e. the gain in brightness/power could lead to a loss in throw as the center reflector needs to be made smaller.

I would also love the idea if Sofirn were to develop a budget-friendly competitor to Imalents R90C (9x XHP35 HI) but without a proprietary battery pack. It should be feasible to run a light like this with 3x or 4x 21700 batteries.

Concerning 26650 batteries: The best high drain 26650s I could find so far are PLB-55A cells (also rewrapped as in "Keeppower 6000mAh" or "Shockli 5.500mAh"), see also here:

https://www.powerlongbattery.com/battery-cells/li-ion-battery-for-electric-vehicle/3-6v-3-7v-5500mah-nicomn-battery-cell-for-evs.html

Maybe Sofirn could find a way to make a deal with PLB and offer these cells rewrapped as "Sofirn 26650" batteries, both in a SP70 Kit-version but also separately on their AliExpress shop. I'm pretty sure these would sell very well as they are hard to get in Europe, almost sold out all the time (see NKON) or only available at high shipping cost.
