Special code for BLF from Sofirn. New arrivals— C8A 2 light group and max up to 1747 lumens.

I also want to thank Tracy for the help on the SF11 Issues. She actually PMed me before I had a chance to send them a message or go through Amazon. My replacement light arrived last week and is working as it should. Very happy with the light now, should make a great emergency AA light.

Hy Tracy

Sent a PM, also experiencing odd behavior.

Is there any way to identify which batch — flaky, or reliable — that a light came from?
I mean, besides sitting and watching to see if it turns itself on …

Looks like I dodged a bullet on the SF11. The aliexpress store listing has 14500 in the title, in the url , and in the description.

I thought “COOL! A light that will use 4 NiMh AAs or 4 Lithium 14500’s!” and placed an order. Then I looked more closely at this thread and the description page, and the seller verified that it won’t use 3.7v 14500 batteries.

So, I’ll be getting a refund for now. I realize 14500 is, technically, the size of a AA, but that seems pretty shady and misleading to so prominently display that in the description since the commonly accepted meaning of 14500 is the lithium rechargeables. But maybe I’m wrong.

Does the tailcap lockout work on your lights?

Is that a way to tell the old flaky batch from the revised batch?

I applaud Sofirn making improvements — but I want something clearly visible showing which batch a flashlight comes from, even if it’s only a painted “v1.1” version number, or a paint dot, or something distinctive.

Sofirn, consider getting some glow-in-the-dark paint to put dots on revised lights. That would be a find-in-the-dark feature worth having, too.

I seem to remember reading somewhere it could use one 14500 but not four of them.

I bought mine at the start of November from the Sofirn store on Aliexpress and don’t have any of the problems.

No half-turn lock-out. There was no listing of it on the store page as a feature so I’m not complaining. The printed manual still mentions it.

No lockout. That’s about my only real gripe with this light. I have one of the bad ones, purchased in May. Tracy had a replacement sent within a couple of days. I’ve had both apart, and there is no difference in the driver. Same model/ revision number. I think they pulled them from Amazon, when they started having issues. It isn’t an issue that will just appear one day, either. It will show up as soon as the light gets heated up. (Or at least thats what everyone, including myself, experienced) Never did figure out exactly what was causing it.

One thought for Tracy/Sofirn — check your driver circuit for susceptibility to “electronic smog” like a cell phone operating nearby.

I have seen other electronics from China that would turn on or off if a cell phone or walkie-talkie radio operated nearby, for example.

I also noticed I could trigger a neighbor’s car alarm by changing modes on a flashlight as I was walking near it (a few years ago, I no longer have that light— not one of yours)

Will Sofirn start selling on Amazon Australia?

Eww. I don’t even trust 2 Li cells in series, so why would you want 4 in series??

All the headaches with matching them, balancing them, etc., just seems like too much of a risk to put the “fire” in “UltraFire”…

I got the Thorfire TK4As, and they’re damned nice for the price. Didn’t find out until after that there was a Sofirn equivalent. :smiley:

Get it, run eneloops in it, you won’t be disappointed.

Thank you very much for you guys kindly feedback of Sofirn light.

SF11 was something wrong in June but we have completely destroyed that products on Amazon and made improvement.

If you met any problem or question, please feel free to contact the sales servers and they will do their best to assist you to solve your problem as soon. We 100% stand with our customers.

Have a nice time on BLF :partying_face:

Would a new version of the SF11 be coming out soon?

I’m getting to like that form-factor, and it’s just a nice simple but elegant design. Very clean.

Improving on the TK4A would make the SF11(A?) a winner. Keep the same UI as the TK4A, but make doubleclick turbo/100% instead of strobe, so this way you’d have instant access to both its lowest and highest settings.

The reflector of the TK4A seems to have some very fine leftover machining marks, making the beam slightly ringy. Smooth it out, and you’d have a perfect beam!

And it definitely needs 2 screws to hold down the emitter. :smiley:

And 4000K-4500K would be perfect!

Tracy, do you only provide these deals with codes by Amazon? I get get anything shipped to Sweden from Amazon. Can you offer discount codes on AliExpress or similar?

Hi Tracy
I would like to buy a sp10b from amazon. Do you have a discount code for this ??
Thank You

PM me if you can.

See post #1 here. Got all colors, too!

Going to be posting a review tomorrow for the SP10B, and holding a giveaway for 3 lights. 2 to the US (Red and Black), and 1 (choice of color) to anywhere else in the world. I will also post the same coupon codes for Amazon (US, non-affiliate code) all three colors.

Thanks for your interested in Sofirn light.
Maybe you can buy these light on Amazon.UK, right? Which one do you want to purchase? Please pm and we would love to offer a code for you. Thanks

Amazon UK can ship to Sweden, but then it’s much more expensive than ordering directly from AliExpress.
I’m really interested in the new Sofirn C8F Triple XP-L W2. I just sent you a PM.

Same here, would there be a discount offer for orders from AliExpress?

Amazon doesn’t ship to the Philippines, or the shipping fee will be very expensive.

Thanks Lightbringer and RobertB!
