LED Flashlights – General Info 18650 Flashlights

@Lux-Perpetua Thanks for those details! This forum is better than the product descriptions.

@RobinVC Where did they announce? I searched before posting but didn’t find anything. Great point on the Astrolux EC01, that is also a contender. The regular pricing seems pretty similar except that the EC01 is on sale now at BangGood. Another difference is the EC01 has an 5000K option.

@SKV89 Anduril as an open-source third-party firmware sounds really cool to play with, but as a muggle myself I like simplicity. The SP40’s UI seems perfect to me if it just added a moonlight mode accessible from off, plus maybe a nice “breathing” mode like the SC31(b).

IIRC the 6000K+ doesn’t have the tint rainbow like the NW emitters - wish NW was a bit nicer :frowning:

Please find the SP33 V3 manual on my sharepoint here:

I’m in their group on facebook, saw it there. But there is also a sofirn development forum post, might’ve seen it mentioned there as well.

10

How many amps is this thing pushing through the led?

And Why is the switch so abysmally…

11

Sofirn’s 26650 HD battery has too much voltage sag to even get close to 3500 lumens. Best to order the SP33 V3 without a battery and get something better. Even Sofirn’s 21700 has heaps of sag at 15A.

12

I regard the SP33 as a near perfect muggle light.
If the UI is similar, the built in charging will make it even better.

13

Am I the only one that is more happy with the older boost driver due to the more even output regulation vs FET? Also assuming PWM on the new driver?

14

Correct, but i prefer the quality and service of Sofirn
If only their design department could come up with more attractive designs though…

15

Yes, their designs are very plain. The IF25 looks terrible

16

I agree with you )

17

Slightly OT: I like the 26650 option as the greater diameter of the battery tube feels much better. Really hope to see such lights in the future, even after 26650 will be abandoned.

18

Nope, same here. I would've took the boost driver with the new UI changes, but.. ordered one regardless.

I also don't like the 150LM Low in the stepped mode, but that is passable, as I'll only be using ramping anyways. Still bugs me why they've chosen again such bright Low level.. :|

Cheers!

19

The TK70 levels are 1, 600, 1500, 2800, 6500. No Ramping. The low of 600 is way too high also.

20

1, 600.. Low.. Oh well.. :|

Greetings Gentlemen,I'm new to the forum.I ordered an SP33v3 from the AliExpress Sofirn Store on 11/13/2019 and it arrived 2 days ago.

I ordered it with the Sofirn 26650 5500mAh battery being that it was a very low cost addition and I own zero 26650 batteries at the time of ordering.The total cost was $32.79.

The box was a bit crushed but the contents were OK when delivered.In the Sofirn box was the SP33v3,1 x 26650 battery,1 x 21700 battery sleeve,1 x lanyard,user guide in 3 languages(English,German,Russian)and a business size thank you card.

Also in the box was a USB A to USB C power cable and 2 O rings that were in the zip lock bag with the lanyard.

The battery was at 3.75 volts and charged to 4.2 volts in an Xtar VC4 @ 1 amp.The volts was confirmed with 2 voltmeters.

A capacity test was performed with cutoff set at 2.7 volts resulting in a 5569mAh reading.After a second charge to 4.2 volts the capacity tested at 5603mAh.

I don't have no way to test lumens but the light in turbo is much brighter than an SF11;the high may also be much brighter.I feel the the light emitted is a bit on the warm side with a dash of yellow/green.

The Sofirn 26650 battery is not a tight fit,there's a bit of wiggle room.An 18650 is loose in the supplied battery holder so it will probably be much better with a fatter and recommended 21700

I have a lot to learn about this flashlight before I place it in my SUV.The size is good for the center console.

No way to add photos from my desktop?

22

No, you’re not the only one who considers a PWM FET DD driver to be a crappy solution compared to a CC boost driver.

23

Thanks for stopping by, whatsthepoint!

No you cannot add photos directly from your desktop.

Here are instructions on how to post pics:

I'm really liking this flashlight.It's very comfortable in the hand but gets quite hot when turbo mode for a few minutes.

This is a good thing that shows the heat disbursement is good?

Being diverse with ability to use 26650,21700 and 18650 batteries is a definite plus.

Flat tops seem to be best suited for the SP33v3 with it's springs on the anode and cathode but button top protected Panasonic18650GA have worked as were as unprotected button top Sanyo 18650GA.

The included sleeve is best with 21700 batteries but even though 18650 are looser they stay connected on the springs.

Turbo Mode with an unprotected flat top Panasonic 18650G was extremely bright and got toasty quickly.

Charging the SP33v3 using USB C to USB C is possible but a charger that will allow it my be hard to locate.

I have 6 USB C chargers and 14 USB A chargers.

All of my USB A chargers with all my USB A to USB C cables worked at charging the Sofirn SP33v3 including the USB A to USB C cable that was included in the SP33v3 box.

Only 2 of my USB C chargers worked and they both were the same model/brand of charger.

They are LG branded and were shipped in the box with Google Nexus 5X phones.They are my oldest USB C chargers.Attaching a U2 USB tester showed it charging at 5 volts and 0.9 amps.The LG charger lists an output of 5 volts and 3.0 amps

Inside the SP33v3 was a Sofirn branded 26650 5500mAh battery that was showing yellow button color before the UCB cable was inserted in the USB C port on the SP33v3.

The side power button on the SP33v3 flashes red when it is charging via USB C
