New Sofirn SP33 V3 !!

And then there were none. :wink:

Thanks for the heads up, smvs!

How about making this light available on Amazon? Then shipping problems, and especially the wait, go away and problem solved.

It is on sale now till 1 april 2020. Lamp + battery for 28.07 euro. https://nl.aliexpress.com/item/4000283536927.html?spm=a2g0z.12010612.8148356.3.454727b9rvQwFf

Anyone tested this light of it have PWM?

Do you mean good PWM or bad PWM? Seeing as it is a FET based driver and no one has mentioned slow or visable PWM, it must use good PWM.

Any kind of PWM. And in what condition is they are detectable. It will take a very bad pwm before anyone comment anything usually.

And different people have different sensitivity to PWM

Well I use mine as bike lights and they don’t have any strobe effect on the spokes in my front wheel the way bad/slow PWM lamps do.

Also when I take beam shots at various settings the pics come out fine, without any bars across the screen.

Hope this helps.

Most flashlights have PWM. The question is, as JasonWW said, bad PWM or good PWM. The PWM frequency in SP33 v3 is approximately 16 KHz (16000Hz). This is a good PWM.

Has this driver been looked at yet? I think someone posted pics, but I can’t remember.

Yes

I thought that was the thread, I just didnt look back far enough, thanks. How do you know the PWM frequency is 16,000 hertz? Did you use an oscilloscope?

Thanks everyone. I think it’s good enough. My SP33v3 is on the way already though.

Sorry for the late reply.
The exact frequency is 15.96 kHz. For measurement, I used a solar cell and an oscilloscope.


Cool. 16 kHz is about what the NarsilM and Anduril drivers use so I doubt anyone can complain.

SP33v3.0 has ‘good’ (fast) PWM. Can detect it only when pointing the light through a portable fan blades.

Here a positive story: I ordered my SP33 V3.0 (5000K + battery version) from China on march 29 and I received it on april 10 in the Netherlands.

Ordered a couple of the new 5000K without batteries on 13 March and tracking still says

“Despatch from Sorting Center

2020-03-25 20:06:02”

Also, AE has moved the goal posts. Originally was supposed to arrive before the end of this month, then suddenly they added two more weeks so now says

“Your order will be closed in: 20 days 8 hours 2 minutes”

@#$%&!

Had to open a dispute.

Seller made a new proposal
Proposal:
Refund US $ 0.00
Comments:
sorry,friend,due to the virus,many airlines closed,so the logistics update will be slower than usual,please understand.hope you can cancel the dispute.

AE settled in my favor.

AliExpress’ Judgment
Purchase Protection is running out, but package is still in transit Valid

Feel really bad about this because I’d placed five orders before with the Sofirn Official Store on AE for seven flashlights and never had a problem either with shipping or manufacture, was extremely satisfied with them all.

Weird thing, ordered a bunch of magnetic charging cables on eBay the other day and they shipped out almost immediately from the same place as the Sofirns originated, Guangzhou International Center — Tracking even listed the flight they’d be on.

Hope Sofirn sorts out their shipping problems.

I’m in (another) dispute with them right now through Paypal. An order from their website that made it to the shipping center on March 20th and hasn’t moved. They give the same response about shipping times.

I keep getting sucked back in trying to order from them because they make great lights at a great price. But almost every order has been problematic. Some have eventually made it to me, but half have never arrived (and that’s not an exaggeration). When will I learn?

My experience with them is you get a phony tracking number. It never shows your package leaving China . Sometimes you eventually get the order and sometimes you don’t .
But for some reason I keep making purchases .
