Sofirn SP10 Pro (AA/14500/Andúril 2) - now available!

[m03da (a bear.)]

Apologies if this has been answered but I can’t seem to find this mentioned anywhere- what’s the driver topology? Is it buck-boost or does it switch to a linear mode with a Li-ion cell installed?

See my reply in another topic :

@thefreeman

The SP10 driver isn’t strictly speaking regulated (on AA) i.e constant current since it’s a constant voltage converter with PWM dimming, the current appears regulated on AA because at constant voltage the LED current vary only a bit with heat (lowers the Vf). A LED with different Vf would draw a different amount of current.
With li-ion it behaves like a FET driver, i.e the current varies with the input voltage.

I knew one of you driver folk must have mentioned that! Thank you

i have just bought the sofirn sp10 pro today. Can you tell me the lumens of the lowest in ramping of Simple UI and Andvanced UI. I am using 14500 battery.
The maxium i think it will be 900 lumens.

And i want the check my version with 15C from off, but i don’t understand the blink, can you tell me?

Thank you.

Congratulations on your new SP10 Pro.

Please look at Post #1, it includes detailed output info.

i want the check my version with 15C from off, but i don’t understand the blink

Version check instructions are in the Anduril Manual. I encourage you to read through the Manual, even though you may not need all the features, it will help to let you know all that is possible.

I hope you enjoy your SP10 Pro… it is a great little light, and the only one that offers Anduril on AA batteries

[daogiahieu]

thank you,

Do you means this output info?

Mode	NiMH	Li-Ion
Eco	0.2	0.5
Low	6	16
Med	32	75
High	133	270
Turbo	308	729

But i think the turbo is 900 lumens, not 729. The eco just said 0.5, but i want to know which the the eco in Simple and Andvanced UI is? I don’t know if anyone test this.

[daogiahieu]

Please some time tell me the lumens of those, thank you guys

" * Default UI: Simple, in stepped mode from 15 to 150 in 5 steps: 15, 48, 82, 116, 150"
→ i think it is 1 lumens, 10 lumens, 70 lumens, 280 lumens and 900 lumens in the Manual of sofirn, right?

" * Advanced mode stepped ramp: 1 to 150 in 7 steps: 1, 25, 50, 75, 100, 125, 150".
I don’t know which lumens are if i set this 7 steps, please tell me.

thank you

I do not remember the default floor setting in Simple, but they are different for smooth vs stepped ramping, and also different than advanced

the lowest possible floor is in Advanced Smooth Ramping, it is 0.01 lumens.

Advanced Stepped Ramping uses a higher floor, I dont recall what number.

all 4 floors can be changed to be the same if you like

[daogiahieu]

thank you, OMG 0.01 lumens, is it the lowest we can set in the andvanced UI? i don’t image it can be lower than this.

i doesn’t change any thing in Andvanced UI, will i have 0.01 lumens at floor level or i need to change some setting?

[Brokearrow]

Hey Jon just curious about comparing the Sp10pro to the Skilhunt 150? The Sp10 is my current favorite but that Skilhunt looks interesting…

[daogiahieu]

Can you mesurment the lumens with 14500 battery, thank you.

[jon_slider]

@daogiahieu

in Andvanced UI, will i have 0.01 lumens at floor level

yes, in smooth ramping

@Brokearrow

comparing the Sp10pro to the Skilhunt 150

the SP10pro has a lower possible floor, but the H150 has no PWM
the SP10pro has Anduril, but I dont like that I cannot find the button by feel. The button is what made me sell all my SP10pro.

@daogiahieu

Can you mesurment the lumens

I do not have any SP10pro now

In case you aren’t aware, it’s not easy to measure lumens. You’d need to build something like this or buy one.

Also, lumens are perceived logarithmically, where you need 4x the lumens to perceive 2x the brightness. So a 100 lumen difference at 1000 lumens is perhaps imperceptible compared to a 100 difference at 200.

Additionally for turbo max lumen modes, some flashlights drop a fair amount within the first 30 seconds or so , not everyone measures or reports at the same time, etc. And then after that, most will step down after a few minutes. Measurement wise, some use the ANSI and measure at 30 seconds, others report the max lumens at turn-on. Battery condition, temperature, and manufacturer variation, etc. can all effect this as well. Many view the “few minute turbo” as not all that important, but rather the sustained output, which can be seen with runtime graphs. Here is the SP10 V3, which should be similar, though a bit brighter than the SP10 Pro, at the cost of all the flexibility that Anduril 2 gives you.

Anyways, I’ve found one other lumen measurement for the SP10 Pro: The YouTuber Smothered Chrome measured lumens at turn on of the SP10 V3 and SP10 Pro, which got 1075 and 896 respectively (877 with a less fresh battery).

Measured a peak of 781lm turbo, and a floor of <1lm (as low as my tube’s luxmeter goes. I do have a different luxmeter with a higher precision but do not yet have a calibration factor for the tube with it. Eyeballing it, probably around 0.5lm or so, but this light does not currently have the latest firmware which should make the lows a bit lower.

Tested with a freshly charged Vapcell H10 and a 4.5 inch Texas Ace lumen tube - see @PetToilet’s reply; I would consider this level of equipment accurate to +/- 10% - to get significantly more precision than that costs several thousand dollars.

If you want me to do a 30s test or a full runtime test, let me know and I can tomorrow, but at the moment I am moving stuff around so I can’t currently use my tube for an extended time during the evening without disturbing my sleeping partner. I can also update the firmware and test again then as well.

[daogiahieu]

thank you, can you test a pick lumens of thoses mode sp10 pro (or 30s) ? , i don’t need full runtime test.

It depends on the battery and the voltage of the battery.

Stock firmware, factory reset, fully charged Vapcell H10.
Simple UI stepped mode: <1lm, 18lm, 92, 297, 795

Advanced UI stepped mode: <1, 2, 22, 70, 184, 416, 850

I do not have a ring for the tube that perfectly fits the SP10 Pro (I am planning to make some new rings soon but so far have not got round to it) so these are probably on the low side of perfect.

Current about 1s after turn on in turbo (relative brightness in percent).

             |   SP10 V3    |  SP10 Pro
-------------+--------------+----------—--
Eneloop      | 6.4 A (34%)  | 7.4 A (34%)
Sofirn 14500 | 4.7 A (100%) | 3.0 A (78%)

Interesting that the Pro has lower current and output on Li-ion, but higher current and identical output with NiMH. This doesn’t feel right, but I’ve double checked all measurements. Both batteries were freshly charged.

Did the root cause of this ever get figured out? Just a hardware driver efficiency difference for anduril compatibility?

[daogiahieu]

Thank you so much. I was surprised that the turbo of Advanced UI is much more than the Simple UI.
You measure those in 30s after the light turn on right? I think may be the turbo is 900 lumens at first but decrease to 850 lumens in 30s.

Ohhh, thanks for that! It might explain why my visual judgement of the output isn’t as expected on a couple of LEDs i tried, my expectations were based on relative output at the same current where i should have been looking at relative output at the same voltage.
I feel a Cslpm1 install coming on

Although i’m now confused as to how @jon_slider 's red XP-E2 transplant works given the much lower Vf of that LED.
Shouldn’t it just be maxed out all the time?
